摘要
变电站在进行综自改造过程中,由于对二次电压切换回路的不恰当并列,导致设备故障事件时有发生,文章以电压互感器二次回路断线故障为例,对保护电压切换回路不恰当并列引起设备故障的原因进行分析,并提出对策。
In the process of reform for substation comprehensive automation system, the improper paralleling of TV secondary switching over circuit leads malfunction on electrical equipment frequently. Taking the TV secondary circuit breakage as an example , this article presents an analysis of their causes and puts forward some countermeasures.
