避免电压互感器二次反送电的措施研究

Study on Measures for Avoiding Voltage Transformer Secondary Reverse Power

针对目前电压互感器二次侧反送电事故时有发生的现象,分析了电压互感器二次侧反送电的原因,归纳出了操作中的注意事项,并提出了一种在二次侧安装防止反送电空开的措施,降低此类事故发生的概率。

The causes for voltage transformer secondary side reverse power are analyzed for, matters needing attention in operation. A measure installed at the secondary side to avoid reverse power air-switch is put forward to reduce accident probability.
