Inspection of norms for the ground loop

When a new living house is being built, the masters of indestructibility are trying to secure it with various means of protection, including against the blow of a bliskavka. For which footwear it is necessary to build the correct grounding circuit for all standards, to that the wine does not guarantee a superior protection. At the link with the cim vinikaє need for the relativistic vyvchenni rules and norms of the PUE.

PUE norms - a selected group of special normative legal acts written under the USSR by the Ministry of Energy - rules for the power of power plants. Given the rules for the installation of electrical installations, a description of how to properly install electrical wiring in residential booths, factory premises and other structures, the stench may describe various outbuildings, as well as the principle of their encouragement. PUE include the mind and laying of communications of electrical installations, hubs, wimoga to the main systems of those other elements.

In most cases, the norms of the PUE are set at the hour of the installation of electric lighting in the life, various premises, and in the streets, villages, territories of the main installations of enterprises. The stench can change minds with the installation of ultraviolet prominence in health-improving structures, advertising with lighting fixtures and more. When laying the wiring at the booths, they turn up to a specific distribution of PUE standards.

In other branches, you can find recommendations on how to build a ground loop, how to install an electrical outbuilding, and other rules for the operation of various electrical installations. More information about the understanding of such possession is written in the Rules for the technical operation of electrical installations of spares (PTEEP).

Today, in order to comply with all the rules of the PUE for installation and installation of wiring of a different type, laying the ground loop or other technical solutions, the variability of such work will be even higher. The reasons for the causes are superficially covered by the norms, dominating the most important statements, and for others they are trying to find an alternative solution. Irrespective of the road, these rules allow you to secure an effective defense against any type of negative factors.

Norm shodo ground loop

Installation of the ground loop is recommended to work according to the standards of the PUE. Such a pidhіd allow zrobiti all nebhіdnі z'єdnannya that podklyuchennya circuit correctly z dotrimannym sіh standards. Tse to ensure the work of the system in the future, zabіgshi negative effects of natural or anthropogenic factors. To build a ground loop with your own hands, following the mother's knowledge in the field of electrical engineering. Before the work, it is recommended to read the necessary literature, as well as to distribute the PUE, which are requested for installation of the ground loop.

Vіdpovіdno to the chinnyh Rules of extensions of electrical installations, the repeated circuit of the obov'yazkovo is guilty of rozmіschuvatsya in the places of exit from any type of budіvl. At the time of the repeated grounding circuit, a natural grounding device should be installed. The rules designate the trimmers of metal structures that are suitable for the ground loop. Among them, it is possible to build solid concrete structures, metal massive details, as if due to sticking out of the ground with most of its surface. Like the circuit of connections in an aggressive environment, such constructions are due to the mother especially for protection. Also, for the grounding element, a water-provided metal pipe is used, as it can dig deep into the ground, or else dodge rails from non-electrifying vents.

Obov'yazkovo it is necessary to pay attention to the PUE point, de show the elements, as it is not possible to win as a ground loop. Before them, one can see concrete structures with metal elements, which are under pressure, as well as pipelines with combustible speeches, scorching and sewer pipes. As such, the contour is to blame for the destruction of the natural earthing walls (soil, foundation for the future), it is necessary to build theoretical expansion and the connection scheme in advance.

Sound, the hour of life of a new life, the grounding circuit is prepared piece by piece, burying the ground of the support. This way is more universal and practical zastosovuetsya more often. This is dictated by the fact that not all places have a friendly mind for natural grounding.

Even more important factor, which flows into the contour, є opir ґruntu. So, in areas with high water content soils, the opir will be low. Significant installation problems are blamed on dry ground. For example, pishchani ґrunti, skelyasti chi kam'yanі spawn zovsіm are not suitable for such robots.
In normative documents, the exact value of the support, the initial rіven roztіkannya struma, is assigned, and as opіr the mother contour is to blame.

There are two types of grounding on the butt electrical installations.

Traditional ground loop. In this case, the main grounding element is to be made from several vertical supports and one horizontal one. The stink of the guilty mother is a round cut and buti are equal. For which you can vikoristovuvat steel lozin, trumpet or rebar. For the best private houses, it is necessary to win the pillars of the great roses. As steel fittings are victorious, you can take 3 of these elements in sizes of 2 meters. The stench is set up in such a way that the equal-sided tricoutnik has become established, as if the place of the installed fittings will be the top of the mental figure. In front of him, like a rose, the installation of supports, it is necessary to die between them. The more space between them, the better. Bazhano, the distance between the grounding elements was less than 1.5 meters. Having perekonavshis, scho vymіri vіdpovіdat normі, you can rozpochati installation circuit.

If the elements will be clogged at the soil, the next step will be to build up the soil between them. You can arrive with the help of the armies at the same height. The grounding of all supports is carried out behind the help of horizontal grounding devices closer to the upper part of the electrodes. According to the norms of the PUE, the order may be prepared but made of steel or midi. You can get the skin element to the transverse electrode for additional help. Such a way is superior, lower ruhom_ fastening (nuts, bolts). As far as the expansion of these electrodes, all stinks can be standardized at the lowest value. When installing the following, outweigh the prevailing supports. The communion is regulated by the rules for powering electrical installations in Table 1.7.4.

For example, as the contour of the preparations from the midline conductor, the wines are to blame for the size of not less than 1.2 centimeters at the perimeter. As for the preparations made from a sheet of black steel, then the comradeship can be larger for 4 centimeters, and the dozhina is cut over 10.

If the grounding circuit is considered for living quarters, it is necessary to place it there, where people are rarely found. Bazhano choose the pivnіchnu side. Oskelki tsya part hangs closer, then the earth saves more water.
Vіdstan to stіn budіvlі may be bigger for 1 meter.

Glibin's ground loop. This type includes most of the nedolikiv, like in the traditional way. Tsey method can be used on the introduction of a modular-stitch system. This design is being prepared at specialized factories and has a certificate. Modular-shtirov system may be low. Nasampered, tse compliance with usim technical norms and standards. Vaughn may be a high term for operation over 30 years. This design has a stable support for the development of an electric charge for any weather minds. The supports are sunk into the ground for 25-30 meters of coals, which ensure the grounding of the great futures.

Such a system does not need to be constantly revised, the shards of it are easy to do. The scheme of the grounding of the grounding of the modular-stirovoi system is simpler;

If the private booth of the room was occupied, before connection, it is necessary to conduct a simulation of the actual readings of the entire system. As soon as the indications are subdued as normative data, then the installation of that connection to the contour was broken correctly. The verification of a similar kind, as well as the re-verification of the connection and the installation scheme, is re-verified by a special certified electrical laboratory. After rechecking, you will see an expert technical paper with a fixed number, and then it will be entered to the Register. Zrobivshi vimіryuvannya in the main areas of zadnannya, as well as opіr, zapovnyuyut technical passport for grounding circuits, draw up a protocol of testing work and sign an act of acceptance into operation of the water system.

Special sockets have been installed at the accommodating guilds, as well as insurance for connecting the door to grounded ones. In order to make the connection, it is necessary to lay a three-wire power cable with a grounding wire. Crim phase and "zero", wired from the "earth" also comes to the outlet. It is necessary to connect it to the glue, stashed between socket sockets.

Before the cob, it is necessary to work out a circuit for the grounding circuit, and it is also necessary to carry out an additional vimiryuvannya. For skin application or a whole house, there are rules for rozrachunkiv. The scheme of a specific life is victorious. For example, take a small zamіsky budinok to the point of respect. For rozrahunkіv grounding circuit, it is necessary to have the following data:

• priming. Clay soil with support at 60 Ohm * m.
• grounding elements. Metal roll with roses: tovshchina - 50 mm, dozhina - 2.5 m, width - 5 cm.
• stand between supports - 2.5 m-code.
• trench depth for construction - 0.7 m-code.
• necessary indicator support for grounding at the sight of 10 ohms.

For rozrakhunkіv usі danі mаyut but perevorіnі to odnієї odnі vіmirіv (for dozhini in metres). From the PUE tables, coefficients are determined for specific climatic minds and the length of vertical supports. In fact, the significance of the support of the soil is taken into account in the theoretical, the weather around the region is pouring into the rozrahunka. Z danim vimiryuvan vikoristovuemo 2 climatic zone.

Vykoristovuyuchi tsі vimiryuvannya that data, with rozrahunka behind the main formula take the value of R = 27, 58 Ohm. In addition, as the value of the support of a single grounding support was determined, it will be victorious when investigating the number of necessary grounding elements in the structure. In times of їх may buti 3. After you have taken away the results of the investigations, it is necessary to put together a smart scheme. Tse allow you to understand the construction and write down the meaning of all the elements of the okremo. The circuit should be saved after installation at the time of the need for repeated work from the ground loop. Oskіlki robiti rozrahunki and the scheme is independently important, you can speed up by pointing values. Ale treba vrakhovuvati ґrunt, for yaky raztashovaniya budinok.
