摘要
并联补偿电容器组由于放电电压互感器二次绕组多点接地,致使部分电容器短路,不平衡保护动作。根据电容器故障跳闸的现象,分析故障发生的原因,查找故障点,并提出相应整改措施。
Due to the discharge of shunt capacitors,the secondary winding of voltage transformer multipoint grounding occurs.This causes part of the capacitor short circuit and the unbalance protection performs.According to the capacitor fault tripping performance ,we analyse the causes of failure ,look for the point of failure ,and put forward the corresponding improvement measures in this paper.
