摘要

局放试验是检测电力设备绝缘状况最为有效的手段之一。目前在中国500 kV电压等级电抗器现场局部放电试验还处于研究摸索阶段。相比变压器局放试验

电抗器局放试验具有试验容量大、试验装置复杂、屏蔽难度大、检测回路电流大等特征。笔者介绍了500 kV电抗器局放试验装置的配备情况

以及试验方法、试验原理和相关计算。试验结果表明

试验设备的配置具备在现场完成1台500 kV、40

0 MV.A电抗器局部放电试验的要求。

Abstract

Partial discharge test is one of the most effective methods for inspecting the insulation condition of electrical equipment.Compared with partial discharge test of transformer

partial discharge test of reactor has the features of large capacity

complicated testing equipment

difficult shielding

heavy current in testing circuit

and so on.In this paper

the configuration of the testing device for 500 kV shunt reactor

as well as its test method

principle and calculation

is introduced.Test results indicate that the configuration of the testing device meets the requirement for spot test of partial discharge of a 500 kV

0 MV·A reactor.
