摘　　要：本文提出了在N2/O2混合气体中随着电极形状和聚四氟乙烯树脂(Tefl on)尺寸大小的改变,其固体绝缘物表面绝缘击穿特性的基本数据。实验中采用的电极为球形电极与平面电极配置和针形电极与平板电极配置模拟准均匀电场和不均匀电场。实心绝缘体为特氟乙烯树脂(Tefl on),直径分别为70 mm和100 mm。使用N2/O2混合率为80%:20%的气体在1~6 atm压力下且相同条件下可以得到不同的表面绝缘击穿电压。In this paper,proposed a basic data of the surface insulation breakdown characteristics in N2/O2 mixture gas with electrode shape and Tefl on resin size.The used of the electrodes are sphere electrode to plane electrode and needle electrode to plane electrode in this experiment.The solid insulators are Tefl on resin with the diameter by 70mm,100mm,respectively.Used N2/O2 mixture rates of the Gas by 80%:20%in 1-6 pressure,Under the same conditions we can obtain different surface Insulation breakdown voltage.
