摘要

通过红外热像检测和油中溶解气体分析联合诊断了一起220 k V电压互感器内部局部放电缺陷

并准确的判断了设备缺陷性质和位置。两种带电检测技术的联合使用

有效的避免了一起严重设备损坏事故的发生。

Abstract

A 220 k V potential transformer inner partial discharge has been diagnosed by the method of combined infrared thermograph and oil chromatographic analysis and the defect property and location has been judged accurately. The combined use of two kinds of on-line detection technology can avoid a serious equipment damage accident successfully.
