摘　　要：在电力系统的正常运行过程中,电容式电压互感器具有重要作用,若其发生故障会对于输变电带来不良影响,因此必须对其可能发生的典型故障进行深入分析,通过制定针对性的预防措施,避免故障的发生。文中以一起500 kV电容式电压互感器(Capacitive Voltage Transformer,CVT)重大缺陷为例,结合其他典型故障案例,分析总结电容式电压互感器的典型故障预防方法,并提出针对性的有效防范举措,希望以此为同类设备的类似故障处理提供经验参考。Capacitive voltage transformers play an important role in the normal operation of power systems.If it fails,it will have a negative impact on the power transmission and transformation,so it is necessary to conduct an indepth analysis of the typical faults that can occur.This can be avoided by developing targeted preventive measures.Based on this,this paper takes a major defect in a 500 kV Capacitive Voltage Transformer(CVT)as an example and combines it with other typical failure cases to analyze and summarize the typical failure prevention methods of capacitive voltage transformers and propose targeted and effective preventive measures.It is hoped that this will provide some experience reference for similar equipment in similar fault handling.
