Attachment of automatic shutdown of the boiler when the energy is reduced. Recommendations for the installation of UAT for a boiler. ELV for a water heater: prices for the outbuilding of the heating connection and the reasons for it.

It is recommended to test the attachment of the connection once a month, testing is carried out for the additional test button, which is placed on the attachment itself. To finish pressing її and at the same moment the situation is created for a round of strum, the attachment is guilty of mittevo to spratsyuvati and to join.

One of the largest possible reasons, vibivannya ELV pid hour of operation of the water heater Termex or Ariston є:

• Ten's insulation collapsed. The problem lies in the fact that its surface has become unbearable, as a result of which the nichrome spiral, as it was in the middle, came into contact with the water in the tank. How to reverse, what problem caused the breakdown of what? If you pull the TEN and clean it from the scale, with a visual inspection, there may be commemorative cracks. To solve the problem, it is necessary to replace yoga with a new one.
• Possibly, there is a coil of struma at your electric meter. The reason could be the old age, in which the insulation broke down, and the dart became naked. Another reason may be inaccurately wired when replacing wiring. It is also possible to damage the integrity of the wiring when the structure is fixed on the wall with flowers, dowels.
• Wrong ELV connection, because of what you posterіgaєte incorrect yoga work that often spratsovuvannya.
• Possibly, with the provision of ELVs you have taken the device for an inconspicuous tension, in the wake of which it is necessary to periodically spratsovuvannya
• Viyshov out of tune with the mechanism itself, it is possible to trap the button to the test, or else the mechanism of the descent, which is spratsovuє in the form of vibration.
• Incorrect placement of DWT in the electric circuit.
• Dotik of bare wiring with a water heater housing so it can itself be the cause of why the machine is vibrating. Tsya injustice lies in what is on the darts, what is in the boilers, the insulation has collapsed, there is a danger of breaking the struma and spratsovuє ELV. To fix a malfunction, choose a boiler and turn it over to the boiler. In the event of a dart with damaged insulation, replace it with a replacement, or replace the insulation with an additional insulating line.

When choosing a defense, there are two options - PZV or a difavtomat, we can try to look at the pluses and minuses of both.

Difaavtomat є Z'єdnannya ELV with a machine gun. Vykoristovuєtsya for zabіgannya coil strumu, and preventing rewiring, її damage under the hour of zamikannya.

How to connect ELV correctly.

Recognize the same information when choosing, operating and maintaining boilers (water heaters) of all manufacturers of manufacturers, you can, if you want to go.

There is specific information on the site, so you can find out specific problems of other people on this topic, if you have already bought a boiler (storage water heater) and in this way you can get rid of them. You will find a list of such problems that pop up regularly, and you will know their solutions.

Іsnuyu two possible options connection:

• Connected to an outlet. Tsya connection scheme is possible for extensions with a small nominal intensity. Another important mind can be manifestly grounded in this rosette, and when installed at the bathroom, it can be watery. If the attachment will be sufficiently large, the socket will become hot, as a result, the gap between the plug and the socket will become weak, there will be a gap in the contacts and spark.
• Connected via additional copper cable, connections directly to the electrical panel and ELV equipment. For such a scheme, a plug and a socket are included, and a switch is required for help automatic vimicach(machine gun), for the help of such a water heater, the defender will be put on the hook for the guard.

The main managers of the ELV (attachment zahisnogo inclusion) є zahist vіd electric shock. The robot is operating in a steady state stream of phase and zero conductors, with an increase in their differences

vіdbuvaєtsya rozryu lanceug. When choosing which one to install, two values ​​are reversed: the power of the struma (it is recommended to choose three more for the value, lower the automatic) and the value of the second turn, which does not exceed 30 mA. To install a boiler, add a type A or type G. In Denmark, a lot of products are presented on the market, but the next thing is more important, such as Legrand, ABB, AEG, even if not varto save on safety.

The main mental safe and reliable service of the boiler is the correct connection to the electric power supply, with the smallest number of con- stant elements. Must be connected to the accompaniment of the accompaniment to the minimum water intake, krіm pіd'еdnannya drot without intermediary to the water heater. Himself the best place arrival electrical panel all the elements are installed in the new one.

Z єї problems and not only, you won’t know anywhere else, what specific people ask, yak anywhere they couldn’t take more support and advice (what stinks themselves tell us). And in a different way, these problems of the flooring are foldable, that for an hour our expert Oleksandr Kholodov deals with people for 10 and more days.

And now the SKIN nutrition is coristuvacha and it’s good for a new one, so that penny stains are lost due to improper operation or repair of the boiler. And here it is not important that the equipment of a virobnik company takes a part in nutrition. Less important is that unique situation, after all food chain vinik, for how to say one good order: "like a delay, it means an outbreak."

During the operation of water heaters, the protection of the water supply plays the most important role in the safety of security and the protection of people in the battle electric jet.

At this hour, water heaters are divided into two types for the amount of water heating:

• storage water heater;
• flowing water heater.

The skin of these two types may have its own peculiarities, but the energy saving principle will be important from the point of view of the electrician.

Now to set ELVs

The scheme of heating the water without intermediary pours into the amount of saved electricity and the power of the electric jet that passes through the boiler system, and as a water heater without ELV, then the risk of injury in the event of a malfunction is significantly increased.

ELV for a water heater must be selected according to the requirements:

• Water pressure heating element;
• Sealy Strumu's electric lines;
• V_dstan v_d water heater to the water supply system.

In the circuit for connecting a water heater to an electric meter, the ELV plays the role of defending people against an electric jet, but if the water heater is grounded, it will be a good supplementary aid to defend. It is not recommended to install a boiler without grounding fahivtsi.

Assigned to the annex of a zahisny connection, it is simply - the streak of a closed lance of electric power with the appearance of a short hum or a coil of a stream in the middle of the lance of the lance.

Take care of the cost of the post-warning of the inlet strum with the strum to go out of the fittings. As soon as the sizes become different, the threads are cut off automatically. Tse secure the protection when the electric jet enters the body of the electric appliances. However, even if a person is struck by a strum, a coil does not emerge from a closed lance, the ELV does not work, even if the force of the strum does not change, and therefore the coil is not detected.

I'll add it to you

Select the ELVs for the boiler following the improvement of the main characteristics of the water heater and the electric line. In this way, if the ELV is correctly selected, the operation of the water heater will be safe and reliable. Sliding to the next step, it was possible to choose zakhisnogo annex:

Installing the device

Under the hour of connecting a water heater to an electric meter, installation of an outbuilding of a cold connection can be done in two ways, and itself:

• Connect the attachment directly to the outlet;
• Connect the attachment to the electric socket under the auxiliary three-wire copper cable.

When the plug is connected to the socket, it is important to remember that it will only be possible to power through it with a small nominal power. As soon as you turn on the hotter electrical appliances, the socket heats up more often, which in an hour will lead to the body and the socket of the plug and the nest of the socket will become smaller. It is also important that the rosette had a grounding system. And when installing sockets at the bathroom, it is necessary to choose the model of the socket with a raised level of water protection.

Connection of ELV to the shield behind the auxiliary three-wire honey dart reduce the risk of poshkodzhennya merezhі, oskіlki plug and socket vіdsutnі. Also, turning on that boiler shutdown will be automatic without interruption. The defender of people in the face of the strum attack should be put on the ELV.

ELV for water heater storage type

This type of boilers may have a slight pressure, and the heating of the water will vibrate in steps by stretching the song for an hour.

Heating water is used for additional tubular electric heaters, installed in the middle of the tank with advanced thermal insulation. Unfortunately, the design of the heating elements is built in such a way that, under the constant influx of an electric jet, corrosion and temperature drops, this element begins to dry out.

It should be done before the water begins to contact with the electrically conductive parts of the boiler design. In such a situation, the body of the water heater becomes under pressure, and as a boiler without grounding, a person can take a blow with an electric jet.

Popular reasons for spaying

Shards, be it technology, are impromptu to serve forever, and it is necessary to periodically review any faults. Particularly worth the cost of electrical appliances. In this case, it is necessary to check whether ELVs are used on water heaters approximately once a month. It is possible to do this when pressing the “Test” button, as I create a controllable situation at the attachment to the coil of the strum and as an addition to the references, the wines are automatically switched off.

Situations, if ELVs are vibrating periodically, and the reasons for which may be rich, but up to the widest ones can be seen:

• Poshkodzhennya іzolyatsiynogo ball tubular electric heater. It depends on the hour of operation of the water heater, electric jet, water and high temperature to repair the insulation of the heating element step by step, and the water begins to contact without intermediary with electrically conductive parts. To re-check a tubular electric heater, it is enough to pull it out of the boiler tank, clean it from scale and conduct a final inspection. Like on yoga surface there are small cracks, which means insulating ball becoming irrelevant and heating is necessary to replace.
• Vitik strumu. Tse mozhe buti viklikano kіlkom reasons. For example, the boiler was connected to the old electrical wiring, the insulation was zapped for a year and through the bare wires there was a short flicker. Or when installing other outbuildings or elements of furniture with a mechanical path (flowers or dowels), the integrity was damaged insulation cover wiring. Also, the reason may be not clear, or pardon the inclusion of ELV.
• The flickering of bare wiring on the body of the water heater. If in a boiler without grounding, the exposed wire starts to contact with the body - it can lead to the fact that the machine will be spratsovuvat, and also increases the risk of an electric shock from an electric jet.
• The ELV was not adjusted to the point of tension and tension. In this case, the ELV when the water heater is turned on can be periodically adjusted, the chips cannot cope with the pressures.
• Incorrectness I will build a zakhisnogo connection. The trigger mechanism can be shifted for the least amount of vibration. Abo the test button began to sink.

Deyakі vyrobniki vodnagrіvachіv complete their attachments PZV - a small block, which is connected to the opening of the lace cord (mostly). It's a pity that some of the extensions go out of tune. About those who need ELVs, which ELVs are attached and how you can replace the staff ELV of a water heater and refer to our article.

Operating principle ELV and recognition of ELV (EPV principle)

PZV (appliance of a shutdown) of appointments for automatic switching on of an electric appliance in the field after moving a differential stream of a singing value. ELV need to be ventilated in the event of an attachment to the guard against the overhead streams (used by the automatic guard). Automatic wimming attachment when short flicker(appear a jet), and ELV turns on attachments when a coil of jets appears on the body (non-current-carrying parts) and on the electric cables (jet-conducting parts) of the water heater. Also, use the attachment that will go in your own great automatic machine and ELV. Such an attachment is called a diffavtomat.

The principle of work I will build a zahisnogo connection is even simpler. Pryvnyu strum, scho to enter the new one, from the outside view of the new strum. І yakscho due to the stock price of 30 milliamps, ELV is automatically rozimkne lansyug. In this rank, the ELV protects people from a possible attack with an electric jet to the hull. electric water heater. Sound the strum of the water heater ELV standard - 30 mA.

Reasons for using the ELV of the water heater

ELV of a water heater, as well as be-yak іnshe ELV, can be used in such situations:

- dotik people to the parts or the body of electrical appliances, who stooped down the line under the strum.

- at the contact of people from the "earth"

- in case of poor insulation and at contacts of the jet-conducting parts and the body

- When replacing grounding and zero conductors

- when replacing the zero and phase conductors and the farthest bunker of people to the parts of electrical appliances, which stumbled under the strum, at once with the bunker with the "earth"

- When cutting zero ( zero explorer) and to a distant zіtknennі people with current-carrying parts and "earth" at once.

Breakdowns of ELVs and the cause of frequent use of ELVs

The hour of operation of the water heater from the ELV is rich in coristuvachіv tsikh priladіv karzhatsya on the part of the ELV. Who can but have the reasons for the ELVs:

- Incorrectness of the most attached. At the water heaters of the Chinese manufacturer (Termex, Polaris) there are Chinese ELVs of unequal density, which often break.

- as can be seen from the previous paragraph, the reason for the special ELV is the substitution of zero and ground conductors. Our minds often have a substitute for grounding vicorist sov. grounding - quasi-grounding. Under grounding, it is possible to get on the ground of zero and grounding conductors. Tsey way vvazhatimutsya grounded. Ale, sorry, ELV is not clear about incorrect zeroing and including electrical appliances.

How to repair ELVs

PZV - foldable electronic attachment, which can be repaired for availability of spare parts for qualifications of an electronics engineer. Most ELVs are not repaired, but changed. Before speech, you need to change the ELV once a month, for which there is a button for the piece generation of a coil on the case. The ELV is shorter than the replacement for the regular attachment of the water heater. And for the availability of such an outbuilding, it is possible to change the standard ELV or a dif-automatic device to a DIN rail. In times of frequent use of ELVs through the presence of neutral grounding, it is necessary either to block normally grounded, or to turn on ELVs.

The admin of the site Vodonagrivach.ru provides services for the repair of boilers in Odessa. Phone for the order at the banner by phone.

The water heaters fit in perfectly with the reality of our life, like a handful of warm water. But stinks can be unsafe for a person, so don’t worry about an electrozakhist.

Functions and principle dії.

1. Zakhist in the form of electric shock at the dot (indirect chi without middle) to the elements of the fitting;
2. Prevention of sleep in case of faulty differential strum.

The principle of operation of foundations on the measurement of the value of the input and output differential streams by the sensor. In a normal state, the blame must be equal, if the balance is disturbed, it means that the wind has risen to the ELV (for example, to the people) and the equipment needs to be repaired. The sensor is the greatest transformer of the struma, the sounding of a toroidal ring looks like a ring. VDT with a relay control element (electromechanical) is more sensitive and superficial than a robot, it functions silently for many years. Recently, electronic ELVs were found, de control is not a relay, but a special electronic circuit. About the reliability of these outbuildings varto speak after the їhnёї trivaloї ekspluatatsії.

Selecting a zakhisnogo annex for the type of water heater

Boilers are charged for the heat of the day by heating the water, which, at their own pace, assigns a working nominal value to the building of the power supply.

Accumulative water heaters, such as Ariston PLUS INOX PW 30, can be installed in any room, heat the water adequately and may have a slight pressure. It is necessary to use them in the most secure way, which allows you to zastosovuvat zahisnі devices with a nominal value of 16A-10mA or 16A-30mA. Index 10 mA - means that in case of faulty struma with a force of 10 mA, contacts will be opened.

Flow-through boilers, for example Polaris Aqua 5.3, become the greatest concern for people. Deyakі models povinnі rozmіshuvatisya without intermediary at the bathroom kіmnati, as close as possible to vlasnik at midnight. In addition, the qi units are too hot, up to 5-7 kilowatts, so for protection from an electric shock, a ZOU 32A-10mA is required.

PZV or diffavtomat

In some accessories, such as the Termex water heater, ELVs are installed directly on the wire cable. The circuit is protected by a jet with a power of 10 mA to 30 mA. Zastosuvannya vbudovanogo sensor reduces the cost of installing additional (wine) protection, saving time for installation and easier operation. Most of the time, in one building with ELVs, there is an automaton installed. Such an attachment is called a differential automaton, it takes significantly less space, it is an electrician, but it is more expensive for a price, a lower one.

Ale still positive side appear at the times of the yoke accessory. Nesumlnnі vyrobniki vikoristovuyut nіkіsnі komplektuyuchi, scho prizvodut z fret like the very diffavtomat, and water heater, scho protect. Also, since the ELV is still installed, then it is electronic and not reliable.

Breakdowns and repairs

Malfunctions of the system can be attributed to two types:

1. I’ll build it out of the way myself. As it was appointed more, zastosuvannya of inaccurate materials to cause damage, even if the product is not insured and certified. Incorrectness is badly manifested before it becomes an unfortunate fall.

You can ask for such reasons:

• breakage of the "Test" button;
• out of the fret of the trigger mechanism;
• strum coil in the middle of the apparatus;
• short-hour strum coil - winkaє through the inclusion of tight chi impulse devices;
• the connection scheme is incorrect;
• old spent in the accommodation.

2. As a rule, ELVs are often used on water heaters, which is better for everything, the boiler itself is fine. Have a chance to live without hot water, the docks of the wines at the maisterna.

Due to the necessary knowledge, it is not recommended for beginners to repair on their own whether they are electrical appliances, including those that have been damaged. Describing the outbuildings behind the structure, the fakhivtsi will be responsible for the repair. Ale, it should be said that the majority of vipadkiv need to replace the device. Ale tse also can signify a qualified person. Self-diagnostics can be done by simply pressing the "Test" button.

Prices

Fallow in terms of tightness of the outbuilding, the number of poles, the type of rozchіpluvach, the functions that are used, as well as the price of the plant on the back of the capital in the capital, are in the following range:

Zastosuvannya looked at devices is not an ideal 100% zahist, the possibility of damage by electricity is still overwhelmed. It is necessary to follow the rules of elementary electrical safety.

Set the ELV to 10mA nominal strum not lower than 16A (so your ELV can be set).
Why set the ELV to 10mA read in the tables at the bottom of the post. Having read it, you can set it to 300mA - you can’t save anything.
After 5 years, in order to better clean up the uzo, read the table below again and replace the ELV or repair the washing machine / boiler / wiring.

I support, dopomig with a choice)

The nature of the injection of electrostrum on the body of a person:

0.6-1.5mA

Zminny strum- Weak stinging, tingling of the skins under the electrodes
Constant strum- Don't get carried away

2.0-4.0mA

Zminny strum- Seeing the struma rose up on the wrist, slightly moving the hand
Constant strum- Don't get carried away

5.0-7.0 mA

Zminny strum- Bolovі vіdchuttya posilyuyutsya in the wrist, accompanied by vessels. Weak pain - in all hands. Let’s try to fix the vessel’s shortness of the m’yaziv and squeeze your hand, into a squeezed electrode
Constant strum- Weakly noticeable heating of the skins under the electrode

8.0-10 mA

Zminny strum- Severe pain and judgment in all hands. Important, but you can cut your hand off the electrode
Constant strum- Stronger visible heating of the shkiri

10-15 mA

Zminny strum- Pain, that the ice is transferred, at all times they are overcome by an hour. It is impossible to tear your hand from the electrode
Constant strum- Even more powerfully, I will heat up like under electrodes, and in the adjacent areas of the shkir

20-25 mA

Zminny strum- Hands paralyze mittevo, it is impossible to destroy them. Severe pain, breathing difficulty
Constant strum- Even more powerful heating of the shkiri, due to the appearance of internal heating. Insignificant shortness of my hands

25-50 mA

Zminny strum- Even stronger bіl in the hands of that breasts. The breath is very difficult. With a trivial overshoot of the strum, paralysis of the breath can occur, or weakening of the heart's activity with ease
Constant strum- Seeing a strong heat, I hurt that judgment in my hands. When the hands are blown into the electrodes, they blame the pain that the ice is transferred, after the judiciary speed of the m'yaziv.

50-80 mA

Zminny strum- The breath is paralyzed in a few seconds. The robot's heart is broken. With a trivial overrun of the struma, heart fibrillation may occur
Constant strum- Seemingly strong superficial and internal heating, strong pain in all hands in the area of ​​the breasts. Difficulty breathing. Hands cannot be broken through the electrodes through a strong bіl at the moment of breaking the contact

100 mA

Zminny strum
Constant strum- Paralysis of breathing with a tribal overrun of the strum

300 mA

Zminny strum- Same day in less than an hour
Constant strum- fibrillation of the heart in 20-30 s; in just a few seconds - respiratory paralysis

Over 5000mA

The breath is paralyzed negainno - in a few seconds. Fibrillation of the heart does not stop, it is possible for the timchasovy zupinka of the heart to pass through the struma. With a trivial overrun of the strum (a few seconds), important opiks, ruynuvannya fabrics. Usually fatal
