摘要

晋东南—南阳—荆门1 000 kV特高压交流输电工程是世界上输送容量最大

电压等级最高的交流输电工程。特高压电气设备交接试验大都是首次开展

尤其对于1 000 kV变压器的局部放电试验

由于试验电压髙

现场环境复杂

对局放量的要求标准髙

因此需要良好的抗干扰检测手段。紫外成像技术是一种能有效发现电晕放电的非接触式检测技术

笔者介绍了紫外成像技术在1 000 kV变压器局部放电试验中检测到的外部电晕干扰

实现了对变压器局部放电试验外部干扰的快速准确定位

进而消除干扰控制局放测量的背景

保证了变压器现场局部放电试验的顺利进行。

Abstract

Jindongnan-Nanyang-Jingmen 1 000 kV UHVAC transmission project is the project of the largest capacity and the highest voltage level in the world. Most of its UHV electric equipment handover tests are the first.Especially for the partial discharge（PD）test of 1 000 kV transformer

better anti-interference measurement method is required due to the conditions of higher test voltage

complex field environment

and higher standard. In this paper

the detection of external corona interference by ultraviolet imaging technology in the PD test of 1 000 kV transformer is introduced. With the detection method

the external interference in the PD test can be located rapidly and accurately

thus the interference can be eliminated to ensure successful PD test.
