摘　　要：文中提出一种新型接地选线原理——零序电流比幅式接地选线,该原理是通过在故障期间调整消弧线圈的容量,使馈线的零序电流改变,并根据故障和非故障馈线的零序电流比值特征进行选线。试验结果表明:这种方法能比较快速而且准确确定故障馈线与非故障馈线。This paper presents a new type of grounding line selection principle, which selects the grounding line according to the comparision of zero sequence current. During the fault period, the capaeity of petersen coil is adjusted to change the zero sequence current of feed line. Then the grounding line is selected in accordance with the ratio characteristics of zero sequence current between fault feed line and non-fault feed line. The experiment results show that this method can quickly and accurately determine which is fault feed line.
