摘要

目前广泛应用于气体绝缘领域的SF

是一种强温室气体

以其取材方便、价格便宜、环境友好、低电压等级下的优良绝缘性能等优点成为新型环保替代气体。文中对N

环境下的绝缘子闪络特性进行了试验研究

测量了不同条件下的雷电冲击50%闪络电压

结果显示:随着气压的增加

绝缘子闪络电压近似线性增加;随着绝缘子表面粗糙度的上升

闪络电压先下降后上升;随着伞裙数目的增加

绝缘子正极性闪络电压变化不明显

负极性则先下降后上升。文中的实验数据和结论为N

在气体绝缘中的应用提供了参考。

Abstract

has been widely used in area of gas insulation

however

it has great greenhouse effect.N

becomes an alternative gas because of its abundant resources

low price

environmental friendliness and good insulation performance. In this paper

flashover characteristics of insulator with N

are tested and 50% flashover voltage under lightning impulse is measured. The results show that flashover voltage increases approximately linearly with the increase of the pressure.With the increase of the surface roughness of the insulator

the flashover voltage decreases first and then increases. With the increase of umbrellas’ number

the flashover voltage under positive lightning impulse doesn’t chan

ge basically

while the negative flashover voltage first decreases a lot and then rises. The results and conclusions in this paper can provide a reference for the application of N
