摘　　要：电容式电压互感器(CVT)是变电站重要的电气设备,高电压线路通过CVT连接到调压装置、电能仪表、保护装置等设备上。当电站或变电站出现事故时,如果没有CVT提供适合的电压信号,那么这些设备将无法正常工作。对某电厂一起CVT高压接线板断裂的故障原因进行分析,制定处理方案,为线路的安全稳定运维提供经验。Capacitor voltage transformers(CVT)are important electrical equipment in substations,through which high-voltage lines are connected to voltage regulating devices,power meters,protection devices and other equipment.Once an accident occurs in plants or substations,the aforementioned equipment will not work properly without reliable voltage signals provided by CVT.This paper analyzes the cause of a CVT high-voltage patch panel fracture fault in a power plant and formulates a treatment plan,which may provide useful information for safe and stable operation and maintenance.
