摘要
文章从不同的角度对一起干式负载柜绝缘击穿故障的原因进行分析,最终确定绝缘击穿是由冷凝水引起的间歇性接地所致.研究还发现,对于三相对地绝缘系统,一相间歇性接地可能引起其它两相产生数倍于电源电压的高压.
Abstract
This paper analyzes the reasons for the insulation breakdown of a dry load cabinet from different per-spectives,and ultimately concludes that insulation breakdown is caused by intermittent grounding produced by con-densation water.This study also finds that for three-phase to ground insulation systems,intermittent grounding of one phase may cause the other two phases to generate high voltage several times more than the power supply voltage.
