摘要

对一起500 kV电容式电压互感器（CVT）投运后二次电压值异常的故障做了简要说明

结合电容式电压互感器的结构和工作原理对其进行了分析

发现CVT电容分压器电容单元安装错误是导致二次电压异常的原因。通过对CVT电容单元的现场调整

消除了故障

电压信号显示正常。同时

对CVT投运前的安装调试工作提出了合理化建议。

Abstract

This paper simply introduces a fault of secondary voltage abnormality in a 500 kV capacitor voltage transformer after operation

analysis based on the structure and operation principle of CVT

and the reason is improper installation of capacitor units of capacitive divider in CVT.Fault eliminates and voltage signals indicate properly after regulation for capacitor units on site.At the same time

advisable suggestions propose for installation and commissioning of CVT before operation.
