摘要
在500 kV变电站采用不拆除高压引线的方法对500 kV电容式电压互感器(CVT)进行试验,并对其接线原理进行分析。通过测量实例与拆除高压引线时的试验结果进行比较,证明了该方法是可行的,提高了工作效率,减少了设备的停电时间。
The method does not remove the HV lead of 500 kV capacitor voltage transformer to do CVT test,and analyzes the wiring principle.Comparative test results by measuring examples and removing high voltage wire,which is proved to be feasible,improves the work efficiency,and reduces equipment outage time.
