1, the top surface of the body buried in the ground should not be less than 0.6 meters depth, angle and pipe should be vertical grounding configuration. In addition to lead grounding in vitro, grounding should be treated with preservatives; the use of galvanized steel, bolted part should lead up brush anti-corrosion paint. 2, in order to reduce adjacent grounding of the shielding effect, the spacing of the vertical grounding of not less than twice the length of the pitch of the level of grounding should be based on design requirements Guangzhou distribution room, not less than five meters. 3, from the grounding of the building should not be less than 1.5m. 4, grounding wire should prevent mechanical damage and chemical corrosion Shandong power distribution room, the ground wire should be in by next hole through the wall, wearing a steel or other sturdy protective sleeve. 5, the grounding line should be at least two different network connected to the ground. 6, each of the ground portion of electrical devices should be a separate ground wire to the ground lines connected to the ground need not be part of several series in a ground line. 7. After laying earthen trenches grounding backfill should be sandwiched and other stones, building materials or waste. 1) switch normal power supply and emergency backup generator power can disconnect between the need to use a four-pole neutral switch, and the two can not be connected in parallel. 2) there is danger of a gas explosion in an area and the risk of dust explosion 10 area outlets, swimming pools, baths and other damp places special distribution room shall be fitted with the neutral and phase conductors together with disconnected electrical isolation. 3) In order to maintain the maintenance, protection of personal safety, be fitted with electrical isolation to endanger the safety of neutral potential isolation. In summary, we have a variety of problems in the design of substation, to be improved in the future. My simple analysis and spotting views for reference only. Inappropriate, please correct me.
