摘要
弧光接地一直是威胁电力电网安全运行的严重隐患 ,经消弧线圈或小电阻接地的运行方式虽然在一定程度上起到了保护作用 ,但也存在着一定缺陷。介绍一种新的保护方法 ,即消弧与过电压组合保护方案 ,论述其原理及特点。
Arc grounding is a hidden trouble that threatens electric power and distribution network. The grounding scheme by arc suppression coil or small resistance plays a certain part in protection, but certain shortcomings still exist. A new protective method ( arc suppression and over voltage combination) is presented. Its principle and characteristic are introduced in order to find a better protective method suitable to China electric power and distribution network function scheme.
