GIS抽真空时绝缘电阻降低的原因分析

On cause of insulation resistance's being lowered when GIS is evacuated

针对GIS在抽真空过程中出现的绝缘电阻阻值降低的现象进行了原因分析。提出了在抽真空时不进行绝缘电阻测试的理由,并提出了测量多个GIS单元绝缘电阻的注意事项。

Analysis of insulation resistance s being lowered when GIS is evacuated is made in the vacuum process.The author put forward the reason of not having the insulation resistance test,and made a number of considerations for GIS units measuring insulation resistance.
