金属氧化物避雷器性能在线检测研究现状分析

Research Status of Metal Oxide Arrester Performance On-Line Detection

指出金属氧化物避雷器在长期承受系统电压作用时会产生老化,导致阻性电流增加使其发热性能变差,因此需要定期对其性能进行检测。在分析避雷器工作原理的基础上,对国内外各种检测方法进行了比较分析,对今后开展避雷器性能检测研究具有非常重要的指导意义。

It is pointed out that the metal oxide arrester will age when subjected to the system voltage for a long time,which will lead to the increase of resistive current and the deterioration of its heating performance,so its performance needs to be tested regularly.Based on the analysis of the working principle of the arrester,the various detection methods at home and abroad are compared and analyzed,which has very important guiding significance for the research of arrester performance detection in the future.
