摘　　要：并联电容器组成套装置作为无功补偿装置在电力网络中大量存在,起到改善电压质量、降低线损的作用,然而由于夏季负荷较大,频发故障,多数是由三相电压不平衡导致的保护跳闸。文章将例举几种常见的故障原因并进行案例分析,提出检修策略,为运行中的电容器组成套装置的运维与检修提供一定参考。As a reactive power compensation device,shunt capacitor is widely used in the power network to improve the voltage quality and reduce the line losses.However,due to the large loads in summer results in frequent faults of shunt capacitors,most of them are protection trips caused by three-phase voltage imbalance.This article will provide cases analysis to illustrate several common fault causes,propose maintenance strategies,and make some suggests for the operation,maintenance,and repair of shunt capacitors in operation.
