摘要
110kV某变电站10kV系统出现了持续的过电压问题,造成母线、多条馈线以及用户设备故障,通过对系统电压、设备损坏情况等故障的分析,找出故障发生原因,采取了改变系统运行方式、投入消弧线圈2种对策,取得了良好效果。
A sustained overvoltage problem,occuring in 10 kV system at a 110 kV substation,created faults on the bus,several feeders and users＇ equipments.By analyzing the faults phenomena of system overvoltage,the cause of faults was found out,The two countermeasures which are to change the operation mode and put the arc-suppression coil into service,were adopted,and the good result was obtained.
