How to robiti the ground loop
Ground loop - tse attachments, appointments in order to ground different parts of the electrical installation. The grounding attachment is even more important for the safety of the meshchants. Often, when buying a country house, or when a cottage is being built, problems with the installation of a salary are blamed on a vlasnik. For real, there is nothing coherent here.
Wash robotic contour
On the efficiency of the robotic circuit, such factors are strongly added, as the power of the soil, the quality, the quantity and the depth of the slag of the electrodes. Before that, as a ground loop, it is necessary to determine the quality of the soil.
ZU miraculously works in peat soils, Syrian clay and loam. And the axis of the skelest and stony rocks of the wines is not functional.
Preparation
To install the ground loop, you need:
- steel coil or electrode;
- steel haze.
It is necessary to entrust a trench from the entrance shield with a booth near the trikutnik with sides of 3 meters of skin. The width and depth of the ditch may be buti in the middle pіvmeter. Grounding is guilty of obov'yazkovo roztashovuvatisya below the freezing point to the ground, otherwise it ceases to work. The top of the trikutnik can be turned up to the booth.
Contour insertion
The steel coils will serve as vertical grounding devices in the structure.
The length of such a little piece can be close to 3 meters. One of the yogo kintsiv needs to be tied down in front. Behind the trioma, the tops of the vikonan trikut trench need to be driven in kutki. (Sharpening is necessary for ease of work).
Now it’s only left to weld a steel smuga around the perimeter and a contour of preparations to them. Ale, the earthing attachment itself is less. Sob it got out of hand, yogo needed to put up a booth with a power shield. To that, from the top of the trikutnik to the power shield, a digging trench was required. Along this ditch for additional steel smog, it is necessary to complete the contour with a shield. The trench is covered with soil.
Opir grounding may not be greater than 4 ohms. You can die yoga for the help of Om - meter. Often, for greater efficiency, split two circuits, then connect them into one and so lead up to the shield.
Final details
The replacement of steel cuts can be made with special haircuts, which are specially designed for the design of contours. When choosing the top and sheet steel, it is important to place respect on the area of the transverse cut. Won may buti over 150 sq. mm. The steel pipe is due to a mother with a diameter greater than 32 mm.
The grounding electrode, regardless of the material, from any production fault, is not guilty of being less than 2 meters of the windrow. When it is on the surface of the electrode, it is not to blame for the daily coatings. Zvichayna farba can make the electrode unsuitable for the contour.
For electricians, steel shears and coils are most often used. However, in some cases, it is acceptable to use midi and steel in the middling cover.
The grounding circuit is necessary for protection from a strum strike. Wanting more wines, of course, does not guarantee the safety of bagmen. To strengthen the memory, you can increase the number of grounding electrodes by driving in an additional 2-3 coils.
In private booths, you can install a contour at the foundation. As a rule, with the correct design of the booth, the grounding circuit will work itself there, and then through the fittings it will lead to the rose under the shield. However, even though the memory was not planned for a long time, it can be planted in the city. When you pratsyuvati nearby, you will be safe. At the time of rapt radiation, the charge instantly rises in the earth. A good place for the contour and pidpillya.
For complete safety, install the ELV as well. Tse add a zahistu switch-on.
