摘要

针对一起电容器回路运行中发生的开口三角电压保护跳闸

结合保护装置记录的电流、电压信号和常规试验信息

对可能导致故障的原因逐项进行排查

将故障元件确定为放电线圈

现场试验验证了放电线圈一次绝缘存在故障

变压比发生变化

查找出了回路的故障原因。

Abstract

As for the operating circuit open triangle voltage protection trip

the causes possibly causing the fault is checked item by item according to the current and voltages signal record by the protection device as well as general information

the fault unit is defined as discharge coil.Field test validates discharge coil’s primary insulation fault

which results in inaccurate transform ratio and circuit trip.
