摘要
本文概述了500kV GIS内部弧光放电的情况,讨论了弧光放电的原因,并建议额定电压≥300kV的GIS的试验程序:以交流电压作老练试验或耐压,然后再作振荡操作冲击耐压。
This paper describes location and appearance of the are discharge faults in 500kV GIS, discusses the reasons of arc failures and suggestes the test procedure for GIS with higher rated voltage(≥300kV).The ac voltage is used for conditioning or ac votltage withstand test and then oscillating switching impulse voltage withstand test is carried out.
