Vertically-arranged conditions for cylindrical grounding modules
2023-12-29 20:07:09
Cylindrical module can be vertical embedded, 1, buried depth greater than 0.6m, the distance between the modules 5m; multiple modules can be connected according to the actual site using a linear connection, circular connection, etc., if the construction site is limited, the distance between the modules can be Appropriately reduced.
2. The connection between the modules uses 40x4 galvanized flat steel, the contact connection must be welded, the welding length of the welding spot is twice the width of the connection line; the welding slag is removed at the welding place, coated with anti-corrosion paint or asphalt; galvanized flat The buried depth of steel is more than 0.5m.
3. When water is backfilled, sprinkle water in appropriate amounts, layered and tamped (modules must be in close contact with the soil in the up, down, left, and right directions, and avoid the incorporation of non-conductive objects such as stones and sticks around the module) until the module is fully hygroscopic (72 hours). Grounding resistance (the compaction effect of soil backfill has a great influence on the measurement results, which must be taken care of).
4. Installation should comply with relevant national and industry regulations.
Hengtai cylindrical graphite lightning protection grounding module can be buried vertically or buried horizontally, buried depth should not be less than 0.6 meters, generally 0.8-1.0 meters.
2, When several modules are embedded in parallel, the module spacing should not be less than 4.0 meters. If the conditions are not allowed, it can be appropriately reduced. At the same time, the value of the module utilization factor should be reduced when calculating the module usage.
3. The poles of low-resistance non-metallic graphite lightning protection grounding modules must be soldered when they are connected in parallel with each other or with ground. Requires welding with the same metal material to ensure the reliability of the connection. The welding length should not be less than 100mm, and it is not allowed to weld or miss welding.
4, welding slag should be removed in the welding area, coated with a layer of asphalt or anti-corrosion paint to prevent pole core corrosion.
5. The backfilling of pits and pits should adopt fine-grained soil as the filling material, and construction waste such as broken bricks must not be used for backfilling. When filling back, it should be stratified. After filling 30 cm of material, add proper amount of water and compact it. Refill, add water and tamping until flush with the surface.夯 Real-time care should be taken to ensure that even if the module is backfilled with soil, the backfill soil is in close contact with the formation without damaging the module itself. After the backfill is complete, it will be moistened again.
6. After 72 hours of moisture absorption, measure the ground frequency resistance of the power line with a ground resistance meter. If you do not achieve the desired goal, you should analyze the reasons and take corrective measures.
The application scope of Quzhou Hengtai cylindrical grounding module products is very extensive. At present, it is mainly used in electric power, chemical industry, communication, transportation and other fields. It is used for grounding such as lightning protection grounding, anti-static grounding, safety grounding and work grounding. The use of cylindrical grounding modules allows many industries to ensure normal operation and development of the work during thunderstorms, so that the operation of the power network is no longer limited by space and seasonal climate.
