摘要
110kV唐台变电站并联电容器自2007年2月投运以来,相继发生电缆头、放电线圈损坏故障,同时,该变电站的用户设备也频繁发生电缆头、电抗器故障。文章通过对变电站所接负荷性质进行分析,对谐波进行测量,找出了引起电容器故障的主要原因,并结合用户侧增容改造工程提出了解决措施与建议。
The faults such as damages of cable terminal and discharge coil occurred successively since the shunt capacitor was put into operation in 110 kV Tangtal substation from February 2007, at the same time, the faults such as damages of cable terminal and reactor occurred fi＇equently in user equipment of this substation. Through the analysis of load nature for the substation and harmonic measurement, the major reason for shunt capacitor fault was found out, and the solution measures and suggestions were put forward combined with the augnent and retrofit project at user side.
