摘要
针对信号注入式小电流接地系统的故障测距方法,分折了系统在带有消弧线圈和用户负载两种情况下的误差,并得出结论:当消弧线圈的电感大于输电线等效电感10倍时,对故障定位无影响;用户负载对故障定位无影响.
Abstract: For the fault distance measurement method of small current grounding system by injecting signal, the error of the method is analysed with arc extinguishing coil and user load in this system, and the conclusions are drawn: When the inductance of the arc extinguishing coil is larger than ten times that of the transmission line, the fault location will not be affected by it; The fault location will not be affected by user load.
