摘　　要：运用短距离无线传输模块将线路上的故障指示器和变电站端的接地故障选线设备有机结合起来,综合判断线路的断线故障、短路故障、接地故障,进行线路故障点的范围锁定,提高故障巡视的效率和查找故障的准确率,大大降低人员劳动强度,消除因人员疲劳而引起的巡视质量下降,降低电网长时间失电给优质服务带来的影响。This paper shows a new technology,which combines the fault indicator on the feeder line and single-phase ground faults picking device at substation together,by using short-distance wireless transmission module.This tech-nology can determine the break-circuit fault,short-circuit fault and ground fault,and then it can lock up the feeder line fault point as well.Therefore,this new system can improve the efficiency and accuracy of fault inspection,re-duce the engineers＇ working intensity,and the influence of the long-time black out on power supply service.
