摘要
电压互感器是电力系统中常见的测量设备,其作用是将高电压信号转换为低电压信号,以供测量、保护和控制设备使用。以一起500 kV电容式电压互感器内部故障为例,分析电容式电压互感器内部故障产生原因,并提出了预防电压互感器缺陷的应对措施。
Voltage transformers are common equipment in power systems,and their role is to convert high-voltage signals into low-voltage signals for measurement,protection,and control.This paper entails a case analysis of an internal fault encountered by an actual 500 kV capacitive voltage transformer,and the countermeasures proposed for preventing capacitive voltage transformer internal faults.
