绝缘子泄露电流及其分析方法发展现状

Insulator Leakage Current and Its Analytical Method

绝缘子的绝缘性能影响电力系统的安全可靠运行,泄露电流检测法是当前绝缘子绝缘性能检测的研究重点。首先从物理模型角度介绍绝缘子泄露电流的形成、发展过程,以及泄露电流在线监测系统,然后在此基础上介绍了三种不同的泄露电流分析方法的发展现状,对这些方法的优缺点进行分析。

The insulating property of the insulator can effect safe operation of an electric system.The monitoring method of leakage current is now research key point of the insulator insultating property.First of all,present the form,developing process and the leakage current online monitoring system of the insulator leakage current from the physical model angle,and then on the basis of this,three different leakage current analytical methods are presented.We have analyzed the virftus and defects of these motheds.
