摘要
对环氧树脂(E51)和聚四氟乙烯在液氮中的工频沿面闪络电压进行了测量。采用环-环电极测量了不同间距下的工频沿面闪络电压,用韦伯概率分布的方法对实验结果进行了分析,得出0.1%闪络概率的工频沿面闪络电压与爬电距离的关系,可为超导电力装置的绝缘设计提供参考。
AC surface flashover voltages of epoxy resin （ E51 ） and polytetrafluoroethylene in liquid nitrogen were measured. The flashover voltages were measured at different electrode distance with electrodes adopted as ring-ring form. The method of Weibull plot was adopted to analyze the experiment results, relationship between 0.1% flashover probability AC voltage and creep distance was deduced to provide reference for insulation design of HTS electric equipment.
