The voltage in electrical circuits rarely becomes stable at 220 Volts, most of the time it fluctuates with the allowable values plus or minus 10%. Pobutov, that computer technique copes with the values of 200 or 240 Volts, but in times of guilt, let's get a short haircut - a technique with great power and vide out of tune.

What are the voltage drops and what are the stench of unsafe

The voltage drops are blamed on typical rich-apartment booths. Livelihood is brought through three phases and, behind the help of a rose-shaped shield, the strum is taken to the skin apartment through one working phase and zero wire. It is important to note that “zero” recognizes the greatest ambition and what is nasty - the guilt of all the bad ones. Apparently, if the baggers turn on a lot of butt fittings at the same time, the electric circuit will know the changeover. Often a manifestation - tse burnout zero dart bіlya base in the shield. Moreover, at the same time, the living quarters of the apartment become connected in phase and the voltage rises to the sign of 380 Volts, which will inevitably lead to the exit from the fret of quiet adjustments, so as not to suffice to zahist.

There are a lot of reasons that could lead to such a situation, but it’s characteristic - the stink of the bed can be dreadful. Substations, like rozpodіlyajut elektroenergіyu, often long ago morally and technically obsolete, moreover, even though they have the power and support at the working station, but often the power for this change did not last for ten years. Constantly growing number butovy electric appliances, and, obviously, growing demand at the substation. Vrahovyuchi the fact that at the time of the last demand, the reserve was replenished at a rate of 4.5 kW - energy savings at that hour and immediately become a daily supply.

The electrical wiring camp is also the best. In addition, considering the situation with unfortunate repairmen, who are building a connection to the global system of electric welding, which means to increase the potential for electric power, through which in some people the situation is caused by switching to the shield. Good, as if in this way it was put in charge, but if there weren’t any and it was hopeful at a calm “maybe” - that’s the situation from replacing the burnt by-button technology and commemorate the budget at the edge of the temple with a crowbar. Luckily, there is a large number of variously manipulative possessions on the market, called for the ability to save equipment in the face of voltage drops.

What are the main tools available for the protection of equipment in the event of voltage drops

Unprepared people are easily versed in the types of outbuildings in those applications, so before buying it is important to learn the theory, so that the mother is informed about those that you yourself need to add. Modern outbuildings divided into sprat types:

zahisnі relay,
transformers, what to lower,
transformers that move
voltage stabilizers,
richly functional add-ons to zakhistu,
automatic vimikachi,
mesh filters.

Let’s take a closer look at the recognition of the possibility of skin attachment, in order to kindly show the overall picture of the security of protection against voltage drops.

Zahisne relay

Be yourself automatic attachment, what should be done when inflowing into a new voltage drop at the railing. Vono turns on electric lanceug vіd mezhі at times, if the control microcontroller registers the increase in indications of the voltage against the established norms. The tension is automatically connected back to the lancets, if the pressure indicators come back to normal.

Її the value of the coristuvach is set independently, for the help of the control system and on the other hand, the controller is guided by itself on the value of the value. The relay oscillators do not vibrate more than 8 kW, at the same time, as the indications for apartments reach 25 kW for an hour, the relay switches off at the pair with an automatic switch, which is the main switch.

A good butt of such an add-on is a VP-16AN relay like a DigiTop picker, which, in fact, is an individual adapter, building protection without intermediary connections to a new electrical appliance short hum that vanity. I will build such a variant to become $12

Lowering and moving transformer

The main purpose of transformers, yakі є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є є ії elektricі ї ї ї, polagaє v zmіnі naprugi snake struma. Dani pristroi work for the mind variable voltage to make a sprig of inductive windings, tied one by one. In the fall, depending on the spivv_dnoshennia of the voltage of the stream, the transformers should be divided into raising and lowering:

The moving primary winding is characterized by a low voltage and a smaller number of turns, and the secondary winding is high. As the name suggests, the Danish attachment increases the voltage and stops the transmission of electricity to significant stations.
At the bottom of the pack, the primary winding is demonstrated high voltage and more turns, and the second one is low. Transformers of this type serve for the distribution of electricity, which is suitable for the needy.

What is characteristic, the transformer, whether of some type of vicorist, is like a lowering one, so it moves, if it is started, having applied a voltage to the return bik. At such a time, the lowering becomes such that it rises, and navpaki.

For their design, transformers are divided into two types:

olives,
dry.

The first variety is a tank, in which there is transformer oil. It should serve as a good insulator and an overnight cold mouth for a magnetic core with windings. As a rule, the same type is most often vicorated at the substations.

Dry transformers can be passively cooled and installed at residential premises and at industrial facilities. Repeated cooling eliminates the problems associated with damaged oil tank tightness, but this method is less effective.

To put it bluntly, the transformer, which is lowered, is necessary for 220 Volts to come to the booths, for the improvement of the penalty. It is unacceptable to apply a slow, high voltage to the substation, and for this purpose, a transformer should serve.

Lower transformers for secondary purposes are not charged at a high price. The variability of the YATP-025 model, which reduces the input value from 220 to 12 volts, becomes $30;

Voltage stabilizer

Tsey attachments of appointments for the support of the singing line of the voltage at the exit. The work of the stabilizer makes it possible to protect the property from an unstable supply of electricity and a surge, as well as failures at the edge.

Podіbnannya zastosovuyut, if there is a sense of protection of electric devices and computer equipment in the form of voltage drops and voltage. Turn on the stabilizer at a different time inner mesh and connect to it, adjust until quiet fir, until the value of the voltage returns to normal.

Zastosuvannya stabilizatorіv allows otrimati nі vnі vаgi:

zahist vіd stribkiv and voltage drops,
usunennya electromagnetic shifts,
zahist in the form of a short chime,
protection of telephone lines, opening and noise on lines,
more low price in por_vnyannі s іnshimi zahisnymi obladnannyam.

The current stabilizers of the changeable voltage, which zastosovutsya at the butt, are mentally subdivided into such differences:

mechanical with servo drive,
electronic,
relay,
hybrids,
compensatory,

Models vibrate in two options: single-phase and three-phase; important homemade rice yakіsnogo stabilizer become yogo shvidkodіya zmіnu іvnja vpruga. As a rule, the response takes about a decade of milliseconds. Another important factor in the work of the stabilizer is the accuracy of the output voltage. The value is not guilty of piling up in the boundaries of more than 10% of the nominal value.

Optimal in the choice of models of stabilizers, building vitrimuvat ten times the tension, and for some of them, you need to increase the reserve of tension.

Priya zakhistu richly functional

In the first season, there are appointments for switching on the possession in that case, if the load voltage exceeded the allowable value of the minimum indicator of 160 V or the maximum value of 280. magnetic relay and voltage control. Before them, there is a connection and a varistor, which at times caused high-voltage impulses in the shunt line up to the preset safe value. Particularly, I will add it to the robotic mode and diy, yakі viroblyaє prilad:

At the time of the increase in voltage and the output for the allowable distance, it is necessary to turn on the life. One hour from this timer starts, which is the hour of re-affirmation. In that case, as soon as one more haircut occurs, then the timer is reset and restarted again.
At the time of the appearance of a reduced life, the attachment to the zahistu begins in the wake of the shutdown of the inclusion. In that case, as soon as the term is over, the voltage will not return to normal - it will turn on, as the decrease was short-lived - then it will continue to control the balance of stress.

A similar solution allows you to ensure the safety of the external charge from the injection of impulses, as well as to control the voltage level, as it is supplied to the power supply.

It is important to remember those that the UZM cannot replace by itself, otherwise you can defend yourself, and more often than not, vicorists are like a complex solution to the problem.

Automatic vimikachi

These are one of the most wide-ranging types of solutions for securing an apartment or office space against power surges. Vimikach, which is also called "automatic", controls the strength of the struma in the lance, not allowing superstrings to appear, the strength of which exceeds the value allowed for the conduct. As a rule, it should be used when the connection is switched on, which exceeds the norm on the line, or if it is short-circuited.

Add spratsovuє zavdyakovu vykoristannya in yogo design rozchіpluvachіv, yakі bavayut two kinds:

thermal,
electromagnetic.

The heat is folded from a bimetal plate, which clearly reacts to the changing struma, which flows through it. When overheated, the plate fires a special spring, which turns on the machine.

The electromagnetic principle can be the same principle, with the same difference, that a coil with a magnetic core is victorious, which, when overwhelmed, winds a spring.

The best vikoristovuvaty automatics in combination with an outbuilding zahisnogo inclusion, scho control at tsimu i strum turn. The ELV is also known under the protection of the machine gun and will be automatically installed after zahisnogo vimikacha. Similar to the ringing of a differential machine. As a result of installation, I will add more simple installation schemes and save money on a separate shield.

Filters

Tsі pristroї є podovzhuvachem z a large number of sockets and a button on. As a matter of fact, it is most common to win as a podovzhuvach that space for connecting a personal computer. Zavdyaki varistor presence mesh filter building security protection of the switched on to the new electrical power and suppressing the high-frequency transitions.

When a high-frequency impulse of the opir varistor appears, it drops, due to which the excess electric impulse is converted to heat. Such a solution is to allow the security of the dodatkovy zahist for possession, but not to rely on the mesh filter. Yogo pridbannya dotsily before us as a podovzhuvacha, for the security of the security of possession, it is necessary to give respect to the full extension of the zahist.

Dzherela uninterrupted life

Podіbnі priladi vikorivuyutsya in pershu cherga for quiet outbuildings, raptov vіdklyuchennya zhivlennya on yak, zdatne zadat shkodi operations, scho vykonuyutsya, tobto, to computers. Tse obladnannya poklikane to ensure uninterrupted life, at that hour, as if the stench of the building was blown into the battery, to secure the robotic computer in one hvilin to a decade.

We are buying them in order to “win an hour” with the rapt electricity turned on, in order to allow us to save all the necessary data and operations on the computer. Internal attachment without interruptions similar to stabilizers, the difference can be seen only in the presence of a lead battery.

Tim is not less, fahіvtsі recommend buying DBZH in case of need for saving data, in case of everything else, stabilizers are given. The head of a small amount of IPL is switched on with a decrease in pressure and lack of sensitivity when moving. Before that, attachments cannot be left without sight, so with the work attached to the computer, yoga is also necessary to turn off. At the same price for a stabilizer and without interruption of the same tightness, it can be different for a sprig of times for the melancholy of the first - the choice is obvious. To save information and safe connection of a computer, download budget models at a price of $45, an hour of work, which is estimated at an average of 15 hvilin - which is enough for a correct completion of work.

Anyway, our electric companies are not able to provide a stable supply of electricity until the end. It’s always going to be broken - sometimes it doesn’t stop, sometimes it’s too much to bring the house home to breakdowns. Zagalom, the middle of 220V gold is rarely seen in the region - ce and є the reason for all our bids, connected with the exit from the fret of the butt fittings. Vryatuvati vіd tsієї adversity may be less than two accessories - tse zahist vіd voltage drops and a stabilizer. Itself about them and timetsya at tsіy stattі, in yakіy world we will understand with the principles of the installation of that voicing electric power supply.

Pristrіy zakhistu vіd prіpіv vprug

This attachment is not more convenient in operation - the principle of yoga robots lies in the fact that, when the tension is screwed up, the voltages of the veins are simply misplaced, in this way they protect the butt technology from burnout. There are two kinds of such devices for protection - a global, building-based one about the safety of all electrical devices, which are near the apartment and the premises, the obv'yazok of such goiter is protected, including one buttress.

The global attachment to the protection of voltage drops is installed directly into the apartment electrical panel, which is selected for the principle of easy connection to make it simple and turn around with a yoga installation, it can be practical leather.

Vіn navit zvnі chimos nagaduє zvichayny podvіyny avtomatichny vimikach, і the principle of this installation is the same. For an additional terminal, phase and zero are connected from one side, which comes from the central machine, and from the other - phase and zero, which goes to the rescue. At the time of stribkiv, the whole apartment is left without electricity.

Deyakі automatically zakhistu viroblyayut z tromamami podklyuchennya (for example, Bars). In this way, the phase is passing (it connects to the new one and comes and leaves), and zero, which connects to the third terminal, does not go anywhere.

Mіsceviy automatic machine zahistu due to voltage fluctuations in which the trochs of loyalty are used - take it in case of yogo spratsovuvannі and do not run out of power without energy. On the right, in the fact that the vin is plugged in without a middle, and even in the new one, more precisely, in the socket installed in the yogo case, the electric appliance is plugged in. In such a way, you can protect the road from the possession of an apartment, as a practical solution - for example, a refrigerator, a gas or electric boiler.

The automatic machine for protection in the event of voltage drops has a simple control principle, it is protected by only two buttons and a touch screen, which are placed on the body of the accessory. As a rule, the left button sets the minimum allowable voltage in the gauge, and the right button sets the maximum. The pressure of the two buttons will be immediately regulated between the hours of the moment and the increase of the attachment, after which the attachment changes the voltage in the measure, and as soon as it is in the frames you have installed, I will re-apply the voltage to the spozhivachiv. Here next to guess the boundaries admissible voltage- As a rule, our industrial fittings are painlessly tested in a measure with a voltage of 180V to 240V.

voltage stabilizers

Tsey way to protect against butovyh spozhivachіv vіd vіd vіd vrugі vіd vіd vіdіv і pіdіlіnіm - vіn іn't znestromlyuє all wiring, but virіvnyuіє prіvnuіє narugu to nebhіdnih parametrіv, rob ії її її stable. The only shortfall of this accessory is the same price. Buy a voltage stabilizer for the gut, not for the skin.

Looking at the expansion, the whole complex of the occupied property is not installed in a small apartment electrical panel - as a rule, the windows are installed in the same place. It’s like real, so it’s a voltage stabilizer for a booth.

It's easy to reach the lansyuga wine. At the body of the stabilizer there are two clamps - two inlets and two outs. Until the entrances, the voltage is applied without interruption to the main automatic switch, and from the outputs, the voltage is stabilized without interruption to the switch.

An even more important moment when choosing a home stabilizer is the correct way to save electricity. You will have to tighten up the tightness of all the accessories, which can be done at once, and add a small margin of 20% to the expansion. For example, if the intensity of the tension is reduced by adjusting your booth to 3 kW, then you need the device for the prevention of tension.

This one, and the other kind of shock due to voltage drops, has a special screen, so that you can control the robot by adjusting it. As a rule, this screen displays input and output voltage. In such a rank, you are not only famous for the power station of the Russian energy system, but also for your house.

Stribki naprugi in elektromerezhі - expanded the problem of zamіskih settlements. It is most often blamed for the hour of cold weather, if there are too many people with electric heaters. Breakdown of the butovy equipment, accidents on the line - it’s better to secure yourself in the future. In our material, we tell you how to save your house from afar, and to help cross the world.

Change the voltage to mischief us in front of them with butovim accessories, for which there are electric motors and compressors - refrigerators, air conditioners, right machines etc. In the event of a lack of exhaustion, the engines warm up, but do not spin, which is allowed to cause the windings to burn out. low voltage drastically reducing the efficiency of heating appliances, micro-furnaces and heating lamps.

Ale all tse - less pіvbidi. Postiyni prosіdannya to talk about those who are working in emergency mode, with shifts. Tse means, early in the morning at the merezhovu statkuvanni it is possible to burn. The most unsafe situation is in the early days of "zero". At tsomu, the voltage on the “phase” can rise sharply up to 380 volts. Todі, zvichayno, burn the mustache of the electrical appliances that work.

It’s necessary for mothers in the country, because the urvish of “zero” is far from being a legacy of revantazhen. Accidents trap and through bad weather: green wires, falling trees strong wind and etc.

Voltage relay (RN)

Tse іntelektualnі prilady, zdatnі razrivati merezh, yakscho napruga in nіy vіyshla for mezhі tasks koristuvavym znachen.

The widest range of electronic relays. The stench will sound like a digital indicator, which will show the current voltage and the robotic mode will fit. Electronic PH for up to 5 thousand rubles, as a rule, stench works out of a strum with a power of up to 16 amperes. The price is approximately equal to the pressure of electric appliances of 3 kW (electric kettle + micro-kilometers and everything). So that such a relay could protect the entire house, connect it through electromagnetic contactors (plus up to 600 rubles and an additional space for 3-4 modules).

Electromechanical relays The voltages are supplied by the lower voltages, they can be used with strums up to 63 amperes (the total voltage of electrical appliances is up to 14kW). There are no digital displays on such relays, and indicator lamps.

Please note that the voltage relay is responsible for the higher rated strum robot, lower automatic switch, after it is installed. For example, if the “automatic” is 32 A, then select a 40 A relay. With electronic - folded. It is necessary to plan well, like groups of survivors, with such accessories they will be stolen.

One more aspect. If you put a single relay for the whole booth, then when the voltage drops, you will lose the power without electricity. Protecting the refrigerator from overheating, the relay turns on the jet, and you turn on the light in the rooms. Therefore, for different groups of supporters, there can be a relay spout - with different adjustments.

The voltage relay is not a fixture that has been found. Prices are charged at 2,500 rubles for Chinese badges of small house pickers. However, in some cases, the replacement of the relay can be replaced with simple fittings.

Rozmikachi minimum/maximum stress (PMM).

This attachment is installed in the electrical panel on a standard DIN rail with an automatic switch. Rozmikach appointments itself in order to turn on the "automatic", as if the voltage is outside the boundary. For which rozmikach may be of special importance, which is inserted into the groove on the body of the "machine". Vimikach and rozmikach are guilty one by one, like a key to a lock, so you can bathe them more quickly at once.

Rozmikachi cost from 150 to 700 rubles. But the inexpensive solution has its own minuses. The threshold for specifying tasks is not regulated by the picker. The widest on Russian market rozmikach RMM-47, the lower threshold of spratsovuvannya is 170 V, the upper one is 270 V. With such an attachment, you can protect no less sensitive equipment - electric furnaces, boilers too thin.

Attach a protection against impulse overvoltage (UZIP).

UZIP of appointments for the defense of the merezhi in the wake of the impact of the bliskavka. If the bliskavka is consumed in the LEP, or if it is discharged here, it’s even close to it, then in the measure, the strain cuts are settled. With a stretch of some milliseconds, it grows dozens of times higher for the same 220 volts.

It could be fatal for "reasonable" technology, as to avenge electronic blocks of keruvannya. Before speech, more voltage relays can easily be brought out of harmony with the same discharges of flashes. Less deyakі mayut spetsіalny zahist.

Two types of UZIP are produced for installation in electrical panels. The first type of building resists direct hits from the bliskavka at the LEP. However, the wines do not extinguish the striae of the tension to the fullest, but zrіzaє, figuratively seeming, only half of the sickness. UZIP of another type is vryatu, so that the order will be charged here. Then you can repay more of the stress of the voltage after the first type of fitting.

An ideal option for a zam_sky booth (especially pobudovany on high) - mothers in the shield UZIP of both types. Well, as a minimum, it is necessary to put an attachment of a different type. At direct hit bliskavki at LEP wines burn itself, but vryatu technіku vryatuє.

Prices for UZIP start at 300 rubles.

Filters

Tse, perhaps, the most popular attachment for the protection of butt technology in the form of voltage strips. And before that, the most beautiful.

The direct recognition of the mesh filter is to extinguish the crossings in the mesh, which is blamed for the hour of the work of some outbuildings. Before such outbuildings, zokrema, blocks of living computers lie.

Transitions that are generated by computers can affect robotic stereo systems and televisions (modern technology, as a rule, is not sensitive to these transitions, so that filters are introduced into them).

Deyakі models of mesh filters can be replaced by fuses, or automatic vimikachi, yak react to overheating. Ale, it is unlikely that the connections are connected to the voltage cut. It’s better to see the room on the shore, and even then, after that, as soon as the electric appliance starts to flicker.

And only one mesh filter can replace the voltage relay. Moreover, this model is no less, lower relay, as it can protect the entire booth.

voltage stabilizers

The most effective extensions for liquidation of drops. The stench of the building "repair" the strain: move what to reduce її for the needs. But they have a low nedolіkіv - the stench is bulky, important, you see the noise characteristic of transformers and dosit expensive. What do you need to know when choosing a stabilizer?

Qi attach buvayut relay and electromechanical. Relays can be installed in a non-salted area. Yakіst їhnёї roboti lie down in the amount of kotushok, so called "steps". Inexpensive models have few cables, and remember that there are voltage drops. Electromechanical work more smoothly, then make more noise and move unstable in the cold.

When choosing a stabilizer, it is important to pay attention to the fact that it can protect against the increased voltage. However, in front of the stabilizer, it is possible to install a voltage relay.

The peculiarity of the stabilizer is that the wine itself will require energy. I chim less input voltage, tim more struma vіn "vіd'їdaє" vіd zagalnogo pie. In this rank, they spend more money on electricity. But it's not the biggest problem.

If in the villages you often run out of power and a lot of summer residents have acquired stabilizers, then they start to work right war. It’s not the summer residents themselves who are fighting, of course, just fit it. When the voltage is reduced, the stabilizers start the daedal brothers with more energy. As a result, the voltage drops even more, and the appetite of the stabilizers increases. Zreshtoy, part of the fittings are overheated and turned on. It’s sacred to decide: the tensions begin to vistachati. Ale, it’s not for a long time, for now, fix it, you’ve come out of the fight, don’t re-vandage. Todi war for energy begins anew. I realized that in such a mode, the stabilizer is unlikely to serve for a long time. For "important" vipadkіv it's better to transfer offline dzherelo electrical supply.

Gasoline power station, or gas generator

Attachment, obviously, is not easy. To make noise, to make noise, to make a fuss, to periodically replace the oil, to preventive work ... And let me not fall for the mercy of electricians and bring light, warmth and the Internet into the mother's booth.

The main criterion for choosing a generator is the need for exhaustion, moreover, it is necessary to take 20 kW from the reserve.

To win respect: fittings with electric motors can reduce energy at start by 3-4 times more than the nominal intensity. For example, a 500-watt refrigerator might need 2 kilowatts to start up. So rozrahunki, to the point, it is necessary to work when choosing not only a generator, but a transformer.

Alée have another vipadku with generators important moment. Absolutely more generators can have two external sockets. And the tension is shared by them equally. To take 4 kW on one line, you need a generator for 8 kW.

You can, obviously, take a strum from both sockets. Ale, ring the wiring in the booth for which it is not attached. From the same time, if there are only a few buds, then you will immediately distribute the calming energy on two lines, so that you can beat the intensity of the generator to the maximum.

Dzherela uninterrupted life(DBJ)

DBZH can be used for autonomous power supply of computers and other office equipment. However, some models can run into tension with hairpins.

The simplest DBZH, they are also called backup, run after the voltage and when you go out of the lane, transfer the computer to live from the batteries. As soon as the voltage is constantly jumping, then the qi flickering often. As a result, the battery quickly comes out of tune.

More slip models - linear-interactive - to put a transformer in their case. When cutting, the voltage of the veins smooths out the wind and does not turbulate the battery. The battery vikoristovuєtsya only as soon as the strum is known. Therefore, when choosing IBR, it is necessary to determine the nature of the voltage at the sockets.

Let your house be safe!

Drop the voltage in electric linesє to finish with a broadened problem. In order to ensure the safety of their own butovih fittings, there is a protection against overvoltage (UZIP) at the booth of the apartment.

See zahishnye outbuildings

Іsnuє kіlka types of zahisnih outbuildings, yakі will help you save your family and how to fix it in case of breakdowns through drops in electric lines. A leather accessory for zahistu in the form of an overvoltage may have its own advantages and shortcomings, we can look at them:

Voltage stabilizer;
Automatic vimic;
Merezhevy filter;
Transformers (lowering and moving);
EPV and stabilitron.

voltage stabilizers are designated for raising the voltage on a normal level. This is especially important in case of unstable robotic electric lines, voltage fluctuations, overvoltage and overvoltage.

ELV- tse zahisny attachment of the inclusion of a fence, which helps to shave an hour, a coil of struma. Golovnym yogo vіdminnіstyu vіd dіfavtomatа i thаt wіth thе voltage drop, PZV pоvnіstu vіdklyuchає elektrika, then diflіk іn phase. This device includes a special squirt sensor, a transformer and an automatic machine, so that it has a lot of functions. The main work of the robot is not controlled by a relay, but by a special microcircuit. You will check the input and output signals of the stream, and then, fallow in the result, turn on the electrical energy, or continue to work with the system of constant monitoring.

DBJ or UPS pratsyuє for the principle of the battery. Tsey butt fitting not only protecting the border of the apartment and the houses from overvoltage, but also helping to protect your utility outbuildings when the electricity is turned on according to plan. This attachment is often used for the protection of a computer, a refrigerator, and a heating machine for the ignition of a microcontroller. If you are afraid of shifting in the measure, then for the help of a built-in transformer DBZH stabilizes the strum, and in case of a sharp turn-on, you can secure the energy by adding it until it is completely discharged. With a different transceiver, the telephone line strum is often regulated.

Block surge arrester– tse vіdminny zakhist vіd short-hour overvoltage (impulsіv) near the fence. Zgіdno z PUE, it is recommended to install them in the shield on the facade of the house, or in any other place, where the live wire enters the house. Danish attachments protect against short and strong voltage drops, which are the most safe for by-butovy electrical appliances (lamps, stationary computers, right cars).

Merezhevy filter(special socket for simistor) sprays a straightening jet at the right energy. Krіm tsgogo prilad prilad prilad prilad and vysokі vantazhennya, yaki often cause damage to the computer and TV.

It is necessary to indicate that at the same time there are a large number of such outbuildings on the market, and there are not many of them mesh filters. They have more than a variator and a special metal dress to carry out a strum. To put it simply, it's a wired socket - a whole electronic switch for home equipment for a relay relay. The main advantage is the simplicity of the robot and the quick response to the transition.

Robot has the largest folding transformers. The stench is more important than vikoristovuyutsya for industrial possession. Їx head components, which are used, є іnduktivnі windings, yakі pov'yazanі one z one behind the auxiliary wiring. Spivvіdnoshennia shribkіv podіlyaє tsі pristroї to increase and decrease. The fallow type of zv'yazku can be counted as a pratsyuє leather from them. For example, in step-down transformers, the primary winding may have a high voltage and a large number of turns, and in quiet ones, which move navpak.

Transformer with expansion tank for oil.

For the help of the transformer, the control of the work of the electrical substations and the installations of the automatic telephone exchange is carried out, which is necessary to control the voltage of the singing electrical lines at large stations.

Also, oily and dry transformers can be vicorated in the same way. The first type of practice is the presence of a special tank, in which oil is known. Tsya homeland is chilling with rotten parts, I will add an hour of work. For distillery: dachas, garages, budinkiv, zastosovuyt simple dry transformers. The stench cools the magnetic conductor for the help of a cold wind.

Under the hour of installation, check that the HNN is an unimportant case. At the moment, there is no special block for the installation of these outbuildings. For reporting instructions we recommend checking out our cover photo. The process may look like this:

In order to avoid strong drops in the hour of lightning strikes, or to induce a new discharge of the attachment (for example, DBZH), it is necessary to change as much as possible between the overvoltage and the ground cable. It is also possible to tweak the add-on to GNN or DBZH scheme Attiny or add-on PIC-controller.

Price overview

You can buy supplies from any electrical goods store. We appreciate your respect that the price may change in the fallow required type I will build a fence with overvoltage and a specific brand (Zubr, Albatross and others).

Let's take a closer look at the versatility of automation:

Most of the time, when you buy sets, you get a discount due to overvoltage.

ACCIDENTAL PROTECTION OF SINGLE-PHASE SINGLE-PHASE MEASURES 220V

Electricity supply for most modern apartments, offices, houses and cottages is based on the apartment shield or the shield for the appearance of electricity. As a rule, the crim of an electric light installed in this shield is allowed to be found in it zahisna equipment at viglyadі zapobіzhnikіv, automatic vimikaіv, PZV, difavtomatіv.

All zahisna equipment, zgіdno z PUE, is recognized as a front for zahistu zvnіshnyoї elektromerezhі vіd nadstrumіv (strumіv short zamikannya) or strumіv perevantazhennya, dzherelom є є spozhivach himself. Differential zahist, to serve as a zahist spazhichacha in the wake of the strumov turn, in which the body can be found guilty of a high potential, the unsafe life of a person. A special protection for the voltage, unsafe for the normal functioning of a large number of electrical receivers, is not transferred to the shields, a priori it is important that the voltage is 220 V, that it comes to us from the fence, do not go beyond admissible norms + 10%.

Vihodyachi z tsogo and vrakhovuyuchi majestic dosvid, savings by the company z rozrobnytstva zahisnih outbuildings, for industrial spozhivachіv, rozpochali release of the original zahisnih outbuildings for butovyh electric lines.

1-phase circuit voltage relay RN-111M for voltage supply up to 3.5 kW (16 A at AC1),

relay RN-113 for power consumption up to 7 kW (32 A at AC1) by mounting on a standard 35 mm din-rail;

relay RN-102 for power supply voltage 7 kW (32 A at AC1) for wall mounting

relay RN-101M type "plug-socket" for zakhistu end switch up to 3.5 kW (16 A at AC1),

voltage relay RN-104, RN-106 "Volt Control" is recognized for the protection of consumer equipment (ownership) (refrigerators, air conditioners, cleaning machines, TV, video and audio equipment, etc.) power up to 9 kW for RN-104і 14 kW for RN-106 in the event of unacceptable cracks, the stresses in the mesh and the shave of the neutral.

relay RN-116і RN-117, - "Plug-socket", which can be switched on without interruption in a merzhevu outlet.

All attachments are based on a modern elemental base, the core of the attachment is the Atmel microcontroller, which allows you to implement folding algorithms for processing the signal, calculating the value of the voltage that should be generated during launch landings, and cancel pardons.

Relays are driven by high pressure, all elements are specially selected and adapted for domestic firrings, to maintain a high reserve of electrical capacity due to overvoltages and operating minds.

Relay RN-111Mі RN-113 can be recruited for direct integration into apartment shields new everyday life, as well as for the reconstruction of the main power supply system,

RN-102 it can be stuck there, de robots involved in the installation and dismantling of the shield are not possible, but economically impractical.

RN-101Mє highly effective additions to the essential protection of the visible mesh filters, voltage stabilizers, DBZH.

The location of the installation of the relay should be determined after the purchaser of electricity, special arrangements for installation with energy companies, it is not necessary. At the same time, electronic devices of electric energy, “electronic sounds” of some kind, like an electric appliance, also require protection from overvoltages. Therefore, due to weather conditions in the energy supply area, the installation of the voltage relay can be transferred to the lichnik.

RN-101M - universal attachment for zahistu pobutovoi tekhnіka and elektronіki potuzhnіstyu up to 3.5 kW.

RN-101M - in case of all accidents in the electric line:
- unacceptable voltage drops
- last shaved neutral
- jet advancement
-Merezhovyh pereshkod.

RN-101M reliably protects electrical devices from faults, turning them on during power cuts and strum shifting.

RN-101M - effectively smoothes high-frequency and high-voltage impulses.

RN-101 M - ensures automatic activation after normalization of the voltage.

RN-101M - the ultimate zahist audio and video, computer and other electronics.

Attachment is not only zahist for tension, but th:

Maє zahist strumom (strumovy automatic vіd revantazhen or short zamikannya).

High-frequency crossover filter (HF filter), which protects equipment from high-speed high-frequency crossovers (important for a thin PC).

A voltmeter is installed, which allows you to look at the magnitude of the voltage in the gauge.

Adjustment of the hour of re-raising from 0-900s. All compressor installations (refrigerators, air conditioners) do not transmit a sharp re-enablement after a voltage drop during the hours of operation and turn off the heaters for at least 3-7 hours, otherwise the stench may burn out.

The helper can set the thresholds for voltage control for additional regulators on the accessory panel.

Attachment can recognize untruthful alarms from unsafe technology. Tse allow for the first time not to turn on the equipment, even in the next few seconds there will be an impersonal change.

Also, it is automatically accelerated spratsovuvannya with sharp haircuts, the voltage is equal - 0.1 sec.

At the RN-101M relay there is a changeover switch - so you switch on the relay more lower than 3.5 kW, turn on the switch, use the strum automatic. The function is not unimportant, even if it is necessary to include in the relay more than 100% commutation pressure before heating, which will preheat the relay contacts. In my line of work, before heating the body made of plastic, the wines can begin to melt, in. wait. For this device, such a possibility is turned off for the account of the visibility of the strum machine at 16A.

In other words, the attachment simply does not let the voltage through, so as to go beyond the framework, installed by the coristuvach. For example, Wee was given 215-237V. As soon as the voltage is viide for the qi value, the relay will turn on the equipment, thereby saving the practicality. And if the voltage turns to a normal camp, I will turn it on again automatically. As if after an hour of repeated activation, the voltage did not return to normal, the relay did not apply voltage to the equipment.

With a streak of ambition, what is acceptable 16 A for RN-111M or 32 A for RN-113 and RN-102, The circuit can be supplemented with miniature electromagnetic relays (contactors), for example, ESB type contactors from ABB, switching jets up to 63 A.

RN-113 RN-112 RN-111M RN-101M RN-117

Group apartment or overhead shields can be used for bazhanniy with other accessories: maximum stream relay RMT-101, which ensures the inclusion of priority (non-priority) recruitment, so that the activation of the entry machine is unaccounted for; OM-110 cold exchange relayі OM-310 for obmezhennya spozhivacha on pouzhennosti, scho allowed.
For the help of these and other relays, different schemes of energy-saving shields, ATS shields, automation and control can be implemented.

Voltage relay RN-104 (RN-106)"Volt Control" is recognized for the protection of auxiliary equipment (ownership) (refrigerators, air conditioners, cleaning machines, TV, video and audio equipment, etc.) voltage up to 9 kW for RN-104 and 14 kW for RN-106 due to unacceptable voltage surges in the measure that last shaved neutral.

RN-104/106:
- safe switching on of the setting, which is protected, as the value of the voltage of the measure goes beyond the boundary, the task is short (after setting the parameters in the measure, it will be automatically re-enabled (reclosed));
- lowering the level of high-frequency shifts;
- Indication chinne meaning input voltage, alarm state and output relay state.
РН-106 can protect from internal overheating through the trip par strumu navantazhennya or nasty contact in the terminal block.

Purpose of UZM-51M

Priya zakhistu richly functional USMпризначено для захисту підключеного до нього обладнання (у квартирі, офісі та ін.) від руйнівної дії потужних імпульсних стрибків напруги, викликаних електромагнітними імпульсами близьких грозових розрядів або спрацьовуванням близьких і підключених до цієї мережі електромоторів, магнітних пускачів або електромагнітів, а також, для відключення possession when the voltage is released beyond the permissible range (170 - 270V) in single-phase lines. The increase in power is automatically switched on when the voltage is restored to normal, after the re-closing is completed.

For the installation of an apartment electrical installation with increased or reduced voltage at the entrance to the apartment panel (at the time of the lichnik) it is advisable to install a voltage control device with an overvoltage control threshold of 250 ... voltages from zatrimkoy 1 ..3 hvilin. The admissible strum of contacts in the annex is not less than the maximum strum of the current apartment - 25 ... 40A (5.5 ... 8.8 kW).

How to protect an apartment from overvoltage, shave zero, confuse phases and zero just too much?

Fahіvtsі recommend putting USM, as it protects from impulse shifts and from increased, reduced voltage.
On food, how to protect the zamіsky budinok (dacha) from overvoltage, shaving zero, interfering phases and zero, at life with a three-phase voltage, fakhіvtsі also recommend putting USM on the skin phase, to that when one of the phases is turned on, the grid will be left switched on.

Robot UZM-51M

When the voltage is applied, the green light comes on. If the voltage is within the allowable ranges, the voltage is switched on from a delay of 6 hvilin or 10 seconds, the relay switches on and the light of the yellow color lights up. It is possible to turn it on by hand as soon as possible until the end of the six-width zatrimka (for example, the voltage of the fence in the boundaries). Under an hour of work, as if the voltage went beyond the permissible limits, the tension is automatically reduced. When the voltage is restored to normal, the USM will automatically break out of the jam for 6 minutes or 10 seconds.
When the voltage is moved in the line over 270V, the UZM turns on the relay from the cutoff 0.2s, when the voltage is moved in the line over 300V, it will turn on sooner<20мс. В случае понижения сети менее 170В УЗМ отключает нагрузку с задержкой 10с, а при понижении напряжения менее 130В происходит ускоренное отключение <100мс.
In the normal operation mode (the relay is switched off), when pressing the “TEST” button, the attachment turns on the voltage, which means that the attachment is functioning normally.
The “TEST” button of the manual winding allows you to turn on the liveliness for the advancement, not checking the end of the trimming hour, or turn it off, as if you need to slow down.
With the appearance in a measure of straining impulses of the voltage, the varistor shunts are shunted to a safe value.

Information :
- fixed blocking for the hour of switching on (re-turning on) on compressors (installed in similar gyros), it is recommended to apply a voltage from the cut-off of 5-6 times from the moment the voltage is turned on;
- UZM-51 is equipped with a tighter polarized relay (maybe two stable ones) so as not to be under a constant voltage, and the voltage is applied to the electromagnetic relay winding at the moment of switching, incl. the climate is changing, the internal heating is moving and the fitting is moving.
