基于报文时序的10kV断路器跳闸故障分析

Analysis of 10 kV Switch Tripping Faults Based on Message Sequence Timing

基于10kV开关跳闸故障的报文时序数据,结合控制回路原理,总结了二次回路引起跳闸、机构偷跳以及合后即分等3种典型跳闸故障的时序图,实现了对故障位置的快速定位。该方法在实际抢修中得到了有效应用,帮助抢修人员快速确定排查方向,缩短故障排查处理时间,提高了配网供电可靠性。

Based on time sequence data and control circuitry,this study summarizes the time sequence diagrams of three typical tripping faults:secondary circuit tripping,mechanism tripping,and instant opening after closing.The analytical method has been effectively applied in practical maintenance,assisting maintenance personnel in promptly determining investigation directions,reducing fault investigation and processing time and improving the reliability of power supply in distribution networks.
