摘要
结合鸡西正阳煤矿６ｋＶ电网实际，研究分析了采用高电阻接地方式对抑制矿井电网过电压和单相接地时冲击电流的效果，指出了高电阻接地方式适用电网的条件和优缺点。
Based on reality of 6kV electrified wire netting in Zhengyang Coal Mine of.JixiAdministration, the paper analyzes the results that earth-contact pattern with high resistance re-strains the excessive voltage and shock electric current of single phase earth-contact.Then its ad-vantages,shortcomings and conditions that it suits electrified wire netting are put forward.
