摘要

近年来

电容式电压互感器故障率高

故障发展快

因没有有效的监测手段

常引发设备事故。本文介绍了电容式电压互感器常见故障及特征

提出通过在线监测电容式电压互感器二次电压变化

及时发现电容式电压互感器早期缺陷

预防设备事故发生

并提出了监测判据和实现方法。采用二次电压在线监测后

电容式电压互感器运行可靠性显著提高。

Abstract

In recent years

CVT with high fault rate and fast fault development

often lead to equipment accidents due to no effective monitoring methods.This article introduces common failures and features of CVT

proposes to find CVT’s defects and failures at early stage by on line monitoring the secondary voltage variation of CVT’s to prevent occurrence of equipment’s accidents.It also proposes monitoring criteria and methods.The reliability of CVT improved significantly after using the secondary voltage on-line monitoring.
