摘要
接地模块是近年发展起来的降低接地装置接地电阻的新技术产品,其作用是依靠接地模块的接地面积和其良好的离子发散性,起到改善大范围土壤导电性能的目的,相当于大范围的土壤改性。该项技术应用在对昔阳白羊岭煤矿110kV变电站的接地装置改造工程中,将接地电阻从2Ω降到0.46Ω,极大地提高了变电可靠性。
Earthing module is a new technical product for reducing ground resistance.It uses the contact area and good divergence of ions in order to conductance improvement of soil.The technique has applied to the retrofit work of 110KV substation grounding in the Xiyang Bai-yangling Coal Mine project.It makes ground resistance reducing from 2Ω to 0.46Ω,which improves reliability of power transformation.
