摘　　要：为了在35 kV及以下电网中发生接地故障时能快速找到故障点,文章对非直接接地电网和接地故障处理过程进行分析,通过接地信号检测方式来缩短接地时间,快速隔离故障点,减少经济损失,提高供电可靠性。In order to quickly find the fault points when grounding faults occur in 35 kV and below power grids,this paper analyze the indirectly grounded power grid and the grounding fault handling process,and uses the grounding signal detection to shorten the grounding time,quickly isolate fault points,reduce economic losses,and improve power supply reliability.
