What is better for a private booth - single-phase or three-phase input

Electricity savings in living booths growing unceasingly. Kozhen, a resident of our country, in perepahunka per capita today saves a lot of energy in times more, lower data, for example, five decades ago.

In the middle of the twentieth century, in a private skin booth, there were all the electric appliances, such as an electric stove, a sprat of light bulbs and, in short, a TV set and a radio receiver. Today, pobutovyh elektropriymachiv just temryava at whether-yakoy zhytlovymіshchennі, and in private booths have become more and more often vykonuvati three-phase cable input. Type of traditional single-phase mesh a lot of people are guided.

Ale, why triphasic measures? I chi varto insanely overwhelmed?

Bagato who cares what three-phase mesh allow more tension to be relieved, so that there are more fittings. We don't call it that. The maximum possible tension is indicated by technical minds on the connection. As a rule, for a three-phase measure, 15 kW per household, and for a single-phase - 10 or 15 kW. It is obvious that the profit for the strain is small, and it may take a few days.

However, do not forget that with the same tightness for a triphasic line, you can vicorate input cable there is less overlap. The reason is known literally on the surface: tightness, and, later, the strum is divided into three phases, a smaller world navantazhuyuchi phase okremo. The face value of the entry for a three-phase line, obviously, will be smaller.

Ale tsi perevagi does not have an exact meaning. It's so important, what kind of wire is at the input cable and rating at the input machine? Much more important is the fact that rose shield for a three-phase mesh, the dimensions are large.

Rest pov'yazano z tim, scho in advance more than any single-phase. Before that, the entry-level automatic wimakach will take three or more modules (like null explorer tezh rozryvaetsya). tezh vіdrіznyayutsya pіdvishchenimi dimensions, so scho vstupny rozpodіlny shield on kіlka tiers for "trifazki" - zvichayna picture.

Tse short triphasic introduction into private booth . And the axis of the possibility of a non-intermediate connection in a merezh of three-phase electrical receivers, asynchronous electrical drives - this is an uninterrupted priority. If you are a happy keeper of a private booth with three-phase introductions, you are willing to greet yourself with a "handicap". Aje asynchronous motors, included in the three-phase line, pratsyut with the shortest energy і mechanical parameters. And the exhausted electrical appliances - boilers, electric stoves, heaters - do not cry out "phase imbalance".

"Phase imbalance" for whom the topic is even more delicate. Since the main line is always three-phase, and it is practically impossible to ensure the same voltage in all three phases, then the voltage in the phases will not be the same. Vikonanny of the triphasic introduction will not help change the situation to a better one - even if you have a lot of different lives. And at the edge of the fence, I’ll fit the appearance, it’s necessary to expand the vanity as evenly as possible. Tse put dodatkovu vіdpovіdalnіst elektrika, kaky vykonuє installation.

In single phase electric lines"Phase peroxide" often becomes the reason why people slow down, switch to a phase that is not far off, and rage at a lower level. mesh tension. The experts of the three-phase introduction do not have similar problems, the stinks of the stink can be connected importantly, in the case of single-phase electrical supplies to the third phase, they did not recognize the passage through the "skew".

The working voltage of the three-phase line is 380 volts. The price is obviously higher for the 220 volts. To that, during the work and operation of the three-phase measure, it is necessary to give more respect.

3 positions of norms fire safety three-phase introduction is also more unsafe, oscalki strum short hum at a voltage of 380 volts, it will be rich.

in such a manner, up to a few three-phase introduction to a private booth can be carried:

1. Necessity to remove permission technical minds on a connection with a local energy and gas company. On the right, to finish the clod and you can get on your nerves, otherwise I’ll end up in failure.

2. Promoted Nebezpeka strikes electric jetі pozhezhna nebezpeka through more high voltage. All the progress of the nebezpeka is no less great and memorable. However, we will not install an additional tripolar automaton of a great denomination without intermediary before the introduction of a house, especially as a wooden house. Tse vryatuє in the form of a short flicker on the input.

3. Large dimensions. For the rulers of the great zamіsk residences, this short period of time is not critical - it is the place of vistachai. The last step is to take this factor to the point of respect.

4. The need for installation at the entrance shield. Zagalo such an approach and for a single-phase introduction will not be occupied, but in the "three-phase" it is still more relevant. And if your individual working zero with great ease can break, but if you threaten with overvoltage at least in one, least stressful phase.

The benefits of a three-phase introduction are:

1. Possibility to re-arrange the transition between phases, unique to the effect of "phase imbalance".

2. Possibility of non-intermediate inclusion to a measure of three-phase straining electrical devices. The most important thing is the triphasic introduction.

3. Decrease in the nominal value of the opening zahisnoy equipment and cut the input cable.

4. In some cases, with a loyal attitude to the side of the energy company, the possibility of increasing the maximum allowable pressure on the reduction of electricity.

In this manner, in practice, the introduction of a three-phase introduction becomes docile for private houses from a living area of ​​100 square meters. meters and more. However, single-phase electrical receivers are more rich, and the advantage can be divided as symmetrically as possible. Also, a three-phase introduction is pidide for those who plan to include three-phase electric receivers in the measure.

For others, the transition to the "triphasic" - the world is not obov'yazkova, it can become more than the cause of an epic headache.

Do you need 380 volts and how to connect 3 phases?

When you are working, you have to think about how the voltage and number of phases need to be started. More and more relevant is becoming 380V in the private sector.

Everyone knows the phrase - voltage 220 volts, 1 phase and 380 volts, 3 phases. And the axis of the stench is revolting, yak surviving and shortfalls during independent planning of electrical wiring in a booth in this article, let's talk.

First of all, discuss the need for a second connection, in this case, 380V, we guess, 220V are taken. Follow our article about phase zero. This article is correct for all apartments without a fault, but for a private house today everything is up-to-date power supply, take 380 volts with 3 phases and how to connect such a measure correctly. Qi nutrition and look at our look.

What is the need for 380 volts for a private booth?

First, a small analogy. Tell me, what's better than that swidshe? Pour a teapot out of three sledges, changing them in the world of desolation, or pour a glass of three sledges until the teapot fills up? The food is not empty, the shards of the same in which case the main power of the home is 380 volts 3 phases in the standard - 220V 2 phases.

Too thin process:

Why in apartments 220, and not 380 volts from 3 phases?

Rest assured, our information does not shock you too much. On the right, in the fact that the introduction of 380 volts is not necessary, then, and the power supply is like a plug, it is not.

Didn't you believe? This is understandable - є introduction of 4-wire (3-phase) and є single-phase input (2-wire). Ale! Zabezpechivshi connection of 380 volts and 3 phases to a private booth. Do you take what? That's right - three independent bets on 220V leather. Got lost?

Let's talk about the physics of electricity. We do not pretend to the Nobel Prize, we will try to win the TOE, in a butt supplement, by looking at the aspects of the snake strum. We can't do without a linear voltage.

Otzhe, in simple words: line voltage - the whole line, what is the name, the same as the change - the whole “wrap”, that is the circle.

Vzaimozv'yazok mizh line that stake can be inserted trigonometric fallows. Irrespective of those that the voltage cannot be related to geometry, all the fallows are well shown by the very trigonometric formulas.

Wrap around the simplest, shtovhayuchi її in three points. roztashovannyh pіd kutom 120 deg, stars and three phases. Yak and staleness of the dovzhina line in the vіd dovzhina of the stake, yak (roughly) є square root h 3( updated, square root of 3), which is approximately 1.73. Otherwise, apparently, with three-phase mesh at 220 volts, we take 127 volts from the booster, and at 380 the booster will have 220 volts. Other voltage standards (GOST) are also subject to this rule. To this very reason, the stagnation of trigonometric formulas in electrical engineering has become commonplace.

Now let's turn to the subtitle, and then back to back a little bit of theory. Start the generation three-phase darts(under tension) that quarter - neutral wire, hot for all three (analog plus and minus in batteries). The voltages can be larger, the smaller the voltage, the less you spend on the transmission of energy.

To reduce the voltage, there are transformer substations, which are distributed to the population. Skіlki? That's right - 380 volts, 3 phases and ti, who supplies the same way, no more problems.

Trochi about 127, 220, 380 volts and more.

Nutrition, why do you often need to get such a load in the net? Tse food varte okremnogo scientific achievements. But we need more power, we have been overpowered, what better for 380 volts, how to connect? It's easy to finish, as you say about darts:

For some reason, if you connect a private booth to an energy-saving supply chain, you will have to wait:

• I will allow the tightness;
• Number of phases (tobto 220 or 380 volts);
• Type of introductory line and attachment to the form of energy (below is a comment why you won’t choose a power supply);
• Tariff to the public (these lien depending on the stage of registration of a private house and the number of tariffs, like a vrakhovu lichilnik - for the lock-up day and night);
• Scheme of connection of the fallow in the capacity of the insulation of the Budinkovo ​​electric line;
• Reliability of grounding of the electric power lines of your donkey. How to properly ground the earth, we already wrote.

It is better to use it to the maximum to the maximum - according to the demanded tension (not less than 15 kW before the three-phase introduction). Dalі zalezhno vіd tsіni nіnі nіtnja nіtnja n_tsevih's minds it is possible to lower vimogi.

Now to the voltage supply. 127 volts - same carelessly tension, as if for a standard force, you don’t drive a struma, but rather “strush” the victim. To reduce the strength of the strum, more "tovst" darts are placed in such nets. Another plus is the ability to draw 127 volts from two-phase generation to 220 volts.

Approximately so pratsyuє power engineering deyakyh kraїn, but all the same theme. And if you talk about numbers, then that’s trigonometry itself, it’s said more about yak:

220 volts is a near-cordon "safe" tension at standard struma forces, which is accepted as a standard.

Come on, you know, that the main one is not enough 380 volts. they didn’t know how to tune, how to connect, but they brought clean 3 phases. When struck by a strum, such a fence can be driven in, wound for obviousness automatic vimics. Please come in safely.

Dekilka rules when connecting 380 volts to a private booth

Persh for everything, safety, as if I never slept on the thought of the idea of ​​connecting everything with my own hands, and the electrical wiring meets the standards.

It’s not necessary to supersede the front paragraph, but the connection of 380 volts to a private house is accompanied by richly heavy security switches, below the standard one-by-one line. Practice has shown that there are significantly fewer problems with fires in such home systems, and less in large electrical networks.

Krym tsygo vlasnik triphaznoi merezhі otrimu sche low perevag:

1. Accuracy to the appearance of electricity. You will not have to pay for a sus_da-zvarnik, scallops with sharp voltage drops in the measure of 220V, the lichilnik should be paid for by those who did not win.
2. If the line is not stranded, then if one or two phases of life are turned on, it will not light up in the booth.
3. Connecting 380 volts to a private booth allows you to switch all types of versatility and tools of an industrial and professional type without switching transformers and worrying about turning on automatics.
4. Be it a tool, powered by 380V, not only tighter, but economical, lower butt, don't pay for extras.
5. 380 volts and 3 phases in mains allow you to forget about starters and streaming in electrical wiring.
6. Mayuchi 380 volts at the entrance, knowing how to correctly connect whether or not another object (a shed, a veranda, a bathhouse, etc.)

The first bonus of such a connection is the number of openings from the energy supply company for the hour of scheduled re-checks. A simple demonstration of a three-phase shield for 380 volts, from the allowable documentation, greatly cools the fuse of the perverted "flicker of the eyes." Such a fence and such an introduction leave little room for manipulation with electricity (and so the economy is decent), so it is worth having a great guest visit.

Therefore, the power supply "what to choose" is not varto - obviously, 380 volts 3 phases, having specified how to connect it correctly and honestly.

Obmezhennia for Vlasniks of full connection

“The greater the freedom and the more important we are for the people, the more we are guilty, we will be responsible for the fencing for the sake of winning them these privileges” (c).

You, singsongly, zdivuetsya, if you know, what are the words of Caesar. It has been a long time since then, but little has changed since then. So, 380 volts і 3 phases - ce і freedom and privileges, but ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї ї іїlyako namagayutsya nemzhit:

• Fit the appearance of a hard standardized one with your own hands You don’t connect them. Moreover, you can choose from the requested list (3-4 names), you cannot buy it on the side. You can do it more precisely, but you can pay cheaper to power engineers;
• Orientovna vartistnost uzgodzhennya pіdklyuchennya pіdmoskov'ї naprikintsі 2014 roku became 80 to 100 thousand rubles. It’s good for him at 220V cost from 35 to 50 thousand rubles. In this way, the surcharge can become from 45 to 50 thousand rubles. Warehouse overpayment payback approximately 9 years, as energy tariffs will be frozen and not increased;
• If you want a great effort with a full connection, then for the tariff you can spend in the distribution industrial enterprises, before the ear of the weather, you will know the list of tariffs and categories of support.

And approximately so, your lichilnik will be sealed - PHOTO 3.

So think, take the right decision, and we, nasamkinets, guess.

If you are 24 years old without interruption sawing on a circular saw, powered by a saw at 220V, then you will pay twice as much for electricity, lower, as well as the same amount of sawing boards on a circular saw, which works in a measure at 38

І tse zovsіm not hot and the figure of the movie. Tse cunning mathematics is sinusoid, the basis of which lies change strum that neutral wire.

Hello everyone!
I’ll come back to the courts and tell you about the other side of the strong foolishness.
"Ha-ha" will not be rich and closer to the end. I would like to bring some koristi.

We lived through the winter without gas. Electric heaters did little to help. There was clearly no tension on all the houses. At the 220-volt outlet, 180 volts lived, and on especially cold days, even less. The power lines stretched across the whole village and went through the zhalyugidny camp. Our booth will remain on the line, wanting the transformer to cost 300 meters from us.

You can actually conduct 380 volts in the booths for exactly 550 rubles, but few people know.

First visit to the branch of IDGC-Center.
Dear lady, we accept documents and two receipts for payment. One for 550 UAH. And a friend for 27,000. Type of connection "under the key" + materials for our account.
Asked chi can be cheaper? Talk like that. If all the robots work themselves, then it’s not 27, but 10,000.
After a deaky hour they took away Tech. think, for some, it is possible to grow mi, and IDGC. Say that I'm fucked up, don't say anything. We are to blame for everything, the electricians do nothing.
A couple of days went to the signing of the agreement.
MRSK is crazy about such a paper. They didn’t stink in their eyes, they asked me to send them to the head office. I had a chance to hand over a signature.
At the 5 days established by law, the hedgehogs were forced to forward the paper from the legal entity. vіddіl, i tі saw a cunning agreement.
Another mat. Having asked the head of REM to come to him, he urged him strongly, chatted, saying that he couldn’t do it any other way, everything was going to pay.

To be honest, I don’t want to prey on you with the legal aspects of standing up. Ale, sing-song, whoever will cicavo and need information. Tim, I give myself permission on my own. vodmovi. Likewise, spend in a similar situation - be healthy! Do not forget the steps for the relevance of the laws, for which you ask.

My head sent to those who do not want to fight for their rights. I did help to spare close to 30,000, wait a minute, chimalo.
With a smooth stroke of the pen, the bandages changed into slips. And the price became consistent with the law - more than 500 rubles. Electricians are now to blame for everything, and we - just put a lichnik at the booth, which with success and was beaten.

They killed everything on a budget and for a minimum.
They sent notifications about the viscons being quiet. minds. For 14 days, the stench is responsible for connecting us.
What's going on here...
Two brigades of fitters arrived. They practiced every day. We installed a spear of stovpiv, stretched 300 meters of the line without the middle of the transformer. Figures, vygіdnіshe novіdnіshe dig digging, nizh on the kilometer of the old line minyat.
They caught it, they began to connect.
They installed a shield with a control light on the foot of their string - "not to be evil." Ok, my people are honest, don't let me steal - let's say we won't.

Before speech. Tsey stovp on the border of my plot. Behind him overgrown the ditch and that very road. Dali - a house of susides.
They threw a stovpa wire to the booth. The electricians brought their own, having tried to open me up ahead of time.

In the background, you can see one of the new stovpiv, which was put on a plot of suds.

We went to the booth, and here I sang my joy at the chief's choir. And you need to say that you have come to join the deputy chief for the implementation of services)) Having arrived, maybe, wonder who didn’t get far to realize the connection for 27K. І obviously maw, with your own introduction, do not connect under any kind of drive.
-And I can’t connect you, - it’s my fault.
- Why why? - I'm amazed.
-And you have an introductory knife switch that cannot be sealed! - Roztіkaєtsya in the joy of the boss.
-Would you like me to see an act about the non-violence of quiet minds?

Awesome!
-And tell someone that TU is not vikonnі in part of the viability of the possibility of filling?

Well, I'll write.

Do you know that tomorrow you will come again and plug it in?

What the fuck?
-And I am not responsible for technical minds for ensuring the possibility of sealing. - I'm starting to laugh.
-Yak not guilty, yakscho zavzhd wine?

I see yoma TU, saju bіlya vіkna, it was bright already vіdrubali and old darts knew.
For sprat hvilin vibigaє nadvir, hvilin p'yat bovtaє on the phone.
Turn around from summaries.
-Connect!

Monteri marvel at the new and see:
- And we won’t introduce you at the booths;

Paragraph 10 of the TU, - I see from memory - but I navit otvіr pierced at the wall and the sleeve was broken, so they didn’t pierce me into Europe.
- Pull drіt. There are no such TUs.
- Well, so it's old ... - I sighed.

At this hour, another saboteur comes out of the street. It's amazing to look at the lichnik. Here it is necessary to say that in the whole village the lichniks stand on the stovpah, but I don’t need it for nothing with my vessels, not for their own rahunok, as it’s customary here.

And what for you another lichnik? Having empty pennies, he hangs on the stovpі. - the child wonders.

That's yours, control. And the tsey - for the documents, the rozrakhunkovy, for him I pay for the light. So you donated pennies for free.
I don't know what you know. Mabut, not knowing what is possible.

At the end of the day, they connected to the entrance machine. The seals were replaced with stickers, so that the bolts could not be twisted. Virishiv quarrel, I say:
- All the same, spit once again.
-Ni, you won’t get to the bolts, we were glued.

I see youma kіlka ways.
- Well, Yakshcho only zatskachami .... Well, you don’t need it?
- It's not necessary.

Gave it a boost. The lichnik was tested. The chief put the food, as we got into the distance jur. warmed up. More precisely, yak jur. Viddilu did not get away to heat us)
Vikhali.

Nasampered, counting on what phase to sit my judges. Remembrance of love until it's ready with flashing light bulbs, having planted a garage and a workshop for the first phase. I know goat.

Lately, the mister of the delyanka arrived, who, having begun to put steps, ale pishov at the entrance. Front man, and brigade in the new front. So the axis of the wines has been expanded, which has come to the right place to practice, virishiv to carry out the modernization of the merezh. Having porahuvav, it is necessary to repair 100 meters of the line, having repaired the material. We bought 100 meters of a single-core dart, which was pulled out exactly on 25 meters of the line. From that hour no more pennies were seen, nearly 10 years passed.
So the axis of the wines is happy, saying that the winds of the wines are on our 300 meters, we are calm in the different phases of the roaming.

At dry surplus. IDGC-Center otrimav 550 rubles. On the shield with a lichnik, I have added 5000.

Do you know what really started everything?
Remember the wiring, and at the same time with it a shield with a nameplate, that entry cable is like a stoup.
We came to the IDGC, and there, on the right, it cost 2500 for the lichnik, and if it was still possible to fight, then 2500 for the input cable happened to be paid, plus all the same 5000 for the lichnik itself and the shield.

So the three-phase connection axis turned out to be cheaper.

For the whole hour of intercourse with IDGCs, there was no call for a worker, who knew that he wanted to work practically free of charge. Yak? Why? What, polls wash the brain?
