电压互感器二次回路断线的应对措施及处理

Countermeasures and Treatment of Voltage Transformer Secondary Circuit Disconnection

基于变电所电压互感器二次回路的实际连接情况,其通常连接有较多的负载,一旦出现断线故障,将可能引起各种保护和测量装置出现误动,进而影响到地区电网的安全性。因此,在对电网维护管理的过程中,应注意分析电压互感器二次回路断线故障的发生现象,判断出故障发生的原因,并针对故障采取科学的处理措施恢复电压互感器二次线路的功能,使地区电网能够安全运转。

Based on the actual connection situation of the secondary circuit of the voltage transformer in the substation,there are usually more loads connected to it. Once it is broken,it may cause various protection and measurement devices to malfunction,and then affect Regional grid security. Therefore,in the process of maintenance and management of the power grid,attention should be paid to analyzing the occurrence of the secondary circuit disconnection fault of the voltage transformer,judging the cause of the failure,and taking scientific measures for the fault to restore the secondary circuit of the voltage transformer. Functions to enable the regional power grid to operate safely.
