电场法带电检测零值绝缘子的研究

Study on Online Detection of Faulty Composite Insulators by Electric Field Method

讨论了高压输电线路上悬式绝缘子串的纵向电场分布。分析存在零值时电场分布的变化后提出了带电检测零值绝缘子的新方法——电场法。

In this paper the electric field distribution of porcelain insulator string on HV transmission line is discussed. Field changes on faulty insulators are detected. And a new method of detecting faulty insulators is put forward. Results of laboratory experiments indicate that faulty insulators could be detected by electric field distribution.
