摘要

简要阐述了开关柜局部放电检测技术原理和开关柜内局部放电缺陷类型

介绍了一例利用暂态电压、超声、特高频综合检测技术成功发现某开关柜热缩电缆终端绝缘对地局部放电的典型案例

并提出了一种开关柜内局部放电声电联合定位方法。

Abstract

This paper briefly describes the principle of switchgear partial discharge detection and the types of switching cabinet partial discharge defect

introduces a typical case about the use of transient earth voltage（ TEV）

acoustic emission（ AE）

ultra high frequency（ UHF） technology to successfully find the partial discharge on heat shrinkable cable-ending in switchgear

and proposes a method of partial discharge electro acoustic positioning.
