How to ground yourself in a private booth with your own hands

For all current help, a private booth can be organized for grounding. What is so necessary for grounding and what is needed?

Electricity in our booths is supplied by two darts. One of them is neutral, and you can stick around with your bare hand up to a new point. On another, there is no voltage and chipati її is not possible - to hit with a strum. Neutral wire at the lifeline substation from the ground.

Such a connection method in professional stakes is called a neutral system, which is deafly grounded, and is designated TN-C. Vіn the simplest and found, zastosovuєtsya for a long time, but not in vіdpovіdaє suchasnym vomogam schodo safe operation elektropriladіv.

For more than a few years, if our grandmothers had a 300-watt prask with the most powerful tool, such a scheme proved true to itself, because it was simple and cheap. No need for an additional additive, cream of plugs with 6 ampere fusible guards.

But at the same time, the quantity, the tightness and the folding of the electrical appliances, which are victorious, gigantic grown up, and for safe operation, the need for special methods of protection is needed. One of these methods is the construction of an outbuilding of a sluice grounding.

The traditional version has a construction with vertical metal rods., driven into the ground on a pevnu clay that zadnah between themselves with horizontal metal smugs Provid arguably fit at the entrance shield, where it comes to the main grounding bus (GZSh). Now the shield has three darts: phase, zero and zahisny.

Tse allows you to transfer the TN-C system to the TN-C-S system, the most safe for the patient. The distribution in the middle of the booth is carried out by a cable of three wires, which allows you to properly ground the housings of electrical appliances and the wiring of euro sockets. What do you give?

First of all, smarten up the robots of modern electrical appliances. All accessories, which are equipped with a plug with three contacts, must be equipped with a grounding terminal for its safe operation.

Sound the blocks of living computers, food processors, micro-furnaces, grills, boilers, cleaning machines, sawmills and other industrial equipment. In these annexes there are pulses of blast, electric motors are wrapped around - the stinks make active shifts.

For rahunok grounding qі reshkodi povnistyu or often compensated. The annexes themselves begin to work more stable, the term of their service is getting better. In a micro-furnace, for example, there is a significant change in the background vibration. The presence at the shield of the GZSH allows you to carry out such a grounding.

In a different way, directly grounding the buildings near the places from the led by the sky - baths, siri pidvali - protecting against the possibility of damage with an electric jet. In the event of a breakdown, the voltage is applied to the body of the lance, the vitality is sharply growing strum, and negligently spratsovuє pristrіy zakhisnogo vіdklyuchennya (PZV). Without grounding the temple, the voltage is overwhelmed on the body, and a person with a tipping torsional will take away an electrical injury.

It is recommended to ground the housings of heating boilers, heating machines, electric ovens, gas cauldrons. Therefore, it is safe to ensure safe operation by adjusting it like for the fluctuation of the fluctuation phase hitting the body, so for the fluctuation of the fluctuation of the fluctuation to the current practice of the ovnishnіh impulsny transitions. In the Internet, there are bridges, if the grounding of the computer case has led to an increase in the number of wires.

Thirdly, the presence of a well-grounded grounding gives the opportunity to organize a blissful co-worker's booth.

Wimogi to the hellish grounding:

• provision of a low electric support between electrodes and soil during the most unfriendly weather periods: dry summer and frosty winter;
• the design is guilty of long-term conservation of its capacity.

Choice of design

Choice of construction

• soil type;
• presence of a free area;
• availability of materials;
• laboriousness of preparation;
• financial possibilities.

Opir between the elements of zahisnogo grounding and the soil is the camp of the soil, the kіlkіstyu and the power of the electrodes, the depth of their zalyagannya. The most suitable loam, peat, volog clay. Dry food and stone soils are important. The greater the stagnation of the elements, the shorter the contact with the ground and the lower opir.

For normal soils, a classic grounding design will be a cheap option, if the vertical electrodes are driven into the ground in a straight line, or at the sight of a tricot and are connected by horizontal slugs for help.

Not a lot of linear roztashuvannya є razke pogreshhennya elektrichnyh authorities with poshkogennі be-yakoy z horizontals. Trikutnik at times is the most important.

For the cob, you need to choose a place for grounding. It must be close to the entrance shield, but not closer than 1.5 meters to the paving. Vertical grounding elements are hammered into a depth of 2.5 - 3 meters. At the time of the knitted layout, the sides of the knitted fabric are of the same size.

With a linear roztashuvannі vіdstanі mіzh verticals sag less, but not closer than 1.2 meters one vіd one. Too close to roztashuvannya do not bring bark, to the one who will be washed away by the roztіkannya struma on the ground, and the versatility and labor will increase.

The horizontal elements are placed at a depth of 0.5 meters on the surface and are connected with the vertical ones for additional storage. Any other day, the day is not allowed by official rules. In the closest to the entrance shield, the kuta of the structure is to fight for the entrance to the house for help. Until the end of the marriage, an M10 bolt is welded, which is why a tire must be wired for insertion into the shield.

Conductor's perforation:

• mid - not less than 10 sq. mm;
• steel - not less than 75 sq. mm;
• aluminum - not less than 16 sq. mm.

It is not possible to plant bushes, trees, or plant beds in the place of zahisnogo grounding. It’s better to put decorative embellishments in this area, so that people don’t go there and children don’t play.

Grounding design scheme

Material for electrodes

As a vertical element, round steel, a coil or a pipe can protrude.

For black steel, the size of the coil is 50x50x5 mm, the diameter of the pipe is not less than 32 mm with a wall of more than 3.5 mm, and the diameter of round steel is more than 16 mm. Horizontal good elements: swag 40x4 mm or a dart with a diameter of 10 mm.

The most expensive option would be zastosuvannya galvanized steel or midi. For midi, the diameter of the round profile is 12 mm, and the diameter of the pipe is 20 mm with a wall of 2 mm. It is not possible to vikoristovuvat armature! The surface has been hardened, it is less electrically conductive and more robust to corrosion.

Robot order

1. Choose a place for accommodation and grounding structure: line or tricot.
2. Amount of horizontal and vertical elements is required it is delivered to the object.
3. The tool is being prepared: shovel, sledgehammer, zvaryuvalny apparatus with electrodes, grinder.
4. Digging a trench of 60 - 70 cm behind the grounding profile. Designated places for vertical elements. Here it is recommended to dig holes. The greater the stench will be, the faster and easier it will be for the vertical electrodes to get dirty.
5. Kutochki and round steel are sharpened and sharpened, and the pipe flattens out at the end.
6. After clogging, horizontal electrodes are welded that tire to the inlet guard.
7. The places of zvaryuvannya are cleaned from scale and treated with an anti-corrosion warehouse, for example, with bitumen. Other parts of the structure cannot be twisted in any way, so that a good electrical connection is made from the ground.
8. The trench is filled with the same soil and trampled down. Zahisne grounding ready.

Reconstruction of the electric support

The next step is to win the support. The food chain is not simple. For vimiryuvannya vikoristovuetsya special prilad - megohmmeter with a set of vimiryuvalnyh darts and probes. The procedure itself is carried out at a small number of stages and lie down in the minds of the minds.

Іsnuyut raznovidi tsgogo prilada with varіznimi methods of vimіru. Among the electricians, there is no single thought, what kind of way and what kind of tool is the best. Until then, all the outbuildings are expensive.

Hardly chi varto to buy an expensive river for the sake of a lonely zastosuvannya. That є sens not to take care of the right independently, but entrust the professionals. Tse will be smarter and cheaper.

Obviously, as if a similar attachment was lying around at the susid, and I was satisfied with it, then the varto knocked down one newcomer.

Megger type "M-1101"

Earthing passport

After the completion of the work-assembly work, it is necessary to fold the passport to the ground loop. At the passport, it is required to bring a chair from the appointed place of rozashuvannya of vertical and horizontal electrodes, indicate the material from which stench has been prepared, the hour of life and death of the opir. The number of data will become a god for the short revisions, I will become a construction.

Connection to the inlet shield

Conducting, scho to go from the protective grounding to the shield, come to the main protective bus for an additional bolt. GZSH is a copper or steel sleeve (aluminum is not allowed!), as it is fastened directly to the shield body. Bolts M10 with nuts and washers on the male side, to which grounding rods are attached.

The grounding conductor of the skin accessory is guilty of being fastened to its bolt. The order on the insulators is to close the zero bus of such a design. Resentments tires zadnuyutsya among themselves tovstim drotom.

It is not allowed to connect any neutral wires from the inputs! Neutral wire in the line is also connected from the GZSH. Automatic, changeovers and ELVs (attachment of the external connection) are connected to the busbars in line with the design scheme.

In the middle of the booth, all wiring is carried out with a three-wire wire. Sob not to confuse the darts among yourself, the phase conductor is indicated by a red or brown color, zero - blue or black, and grounding - yellow-green or white.

Advantages and shortcomings of the rich-electrode grounding circuit

The main pluses are the low variety of materials and those that the main work does not require qualifications. Digging a trench and hammering with a sledgehammer an electrode, maybe a healthy person. Cut that fittings for the help of the grinder is already more foldable, and obviously not enough, the need to brew the elements, as well as vikonat, it’s possible just a zvaryuvalnik.

Another one of the hundred shortfalls of such a design is the lack of maturity of the sporud, as to become 5 - 15 years fallow due to the nature of the soil and the quality of the preparation of the contour. As if there were wake-up calls on the food ground, then there will be problems with reaching the required size of the grounding support.

In general, this method can be characterized as a little vitrate, aluminous and laborious, not attached to all types of soil. Then the main jobs can be carried out independently, without hiring professional workers, so you don’t have to work hard at your job.

Modular grounding

There is one more way to create a protective grounding - a modular grounding. This is the most modern design, as if Volodya is rich in achievements, but it is significantly more expensive for the traditional.

In case of any fall into the ground, a five-meter streak is hammered into the ground, galvanized or middling. The same pin is screwed to the same pin and hammered deeper, and so on. Such a modular installation can reach a depth of 30-40 meters.

In the process of growing and driving pins, a support is to be made. As a rule, at a depth of 10 meters it already becomes close to 5 ohms, which is sufficient for grounding. Characteristics of the soil on such depths are more stable than the stretch of earth. Obmezhenі shtirі stіykі to korozії, and the whole system saves its power for dozens of years.

There are firms on the market that supply sets of such grounding devices with detailed installation instructions. Pong can do all the work. Modular grounding is carried out for a few years, does not require large views of the area and can be installed at the basement.

With this option, you should get to know more closely and comprehensively evaluate the financial and hours spent in the traditional way.

The choice of the way that the design of the sound grounding is determined by the master of the booth.

Grounding scheme for a private booth

1. It should be supplied more appropriately to the choice of the grounding structure and the capacity of the work. Rework or repair the circuit more stomly and more laborious, less laborious.
2. Yakshcho on the end of the vertical coil, weld sweat and sharpen then such an electrode will be easier to drive into the ground.
3. More important than a sledgehammer, more important than mahati, but it’s easier to score. The most widened vaga sledgehammer 6 - 8 kg.
4. Electrode circuit is easier to hammer yakscho stench roztashovani strictly vertically.
5. Change, that the reinforcement is welded along the contour of the zіtknennya, and not “pinned” by the folds. It is necessary to ensure the necessary and reliable electrical contact.
6. Do not forget to resolutely acquire a place of zvaryuvannya with an anti-corrosion warehouse. Hello yourself!
7. It is not allowed to replace the seals with threaded ones! Over time, the electrical contact in such circuits is bound to break down and the circuit to waste its grounding power.
8. The trench needs to be filled with the same earth, which was in it, well tamped. The great stone needs to be wikinuted. It is not possible to fill the trench with buddіvelnym smіtty and with tricks of the chains, not to destroy the electrical power of the soil.
9. Regularly check the camp carried out at all missions conduit wires from the terminals.
10. Follow the temperature of plugs and sockets. If the stench is heating up, it means that here the filthy contact has been made. Yogo requires obov'yazkovo to know that pіdzhati.
11. Conducting the ground loop is responsible for connecting to the neutral only once - at the shield. More than in any other place the stench is not guilty.
12. Remember that grounding is safe for the nadіyny zakhist only at the same time from the outbuildings of the external connection (PZV).
13. Yakscho viniklo nutrition - read PUE(Rules for the installation of electrical installations) or consult a competent electrician.
