中性点不接地配电系统中使用自动重合器必须注意一些特殊要求。当相对地发生故障时,邻近馈线相对地之间会产生特别的容性故障电流,故所有配电网络需要配置检测故障方向的保护功能。图1使用自动重合器实例示意图如图1所示,R4重合器下游末端馈线发生一个故障,通过变电所的中压母 Neutral point ungrounded distribution system using automatic recloser must pay attention to some special requirements. When a fault occurs relatively, a special capacitive fault current will be generated between adjacent feeders relatively. Therefore, all the distribution networks need to be configured with the protection function for detecting the fault direction. Figure 1 Schematic diagram of the use of auto-recloser As shown in Figure 1, R4 recloser downstream feeder occurs a fault, through the substation of the mother
