摘要

本文介绍一起110 kV线路型电容式电压互感器（CVT）投运后出现的过热故障

结合电容式电压互感器的结构和工作原理

对故障CVT进行检测和解体分析

找到了故障原因是内部阻尼器造成

提出了投运前的安装调试不一定能发现设备的所有隐患

投运后对设备进行红外检温是判断设备运行工况的一种有效方法

对CVT投运前的现场交接试验和日常安全可靠运行提供指导性的建议。

Abstract

In this paper

an overheat fault of capacitor voltage transformer（CVT）after operation at110 kV line is introduced. The faulted CVT is detected

disassembled and analyzed based on the structure and principle of CVT. The internal damper is the reason of such fault. All hidden troubles of the equipment cannot be found definitely during the installation and commissioning before operation. One effective method to judge operation condition of the equipment is to perform infrared temperature detection after operation

which can provide constructive suggestion on site commis sioning test and daily safe and reliable operation.
