摘要
研究极不均匀场中SF6气体-绝缘子界面在振荡与非振荡冲击电压下的闪络特性后发现绝缘子的闪络特性后与冲击电压的波头及波尾振荡频率均有很大关系。频率为4MHz的快速振荡冲击电压作用下,绝缘子的闪络电压明显低于非振荡冲击电压作用下的结果。
This paper studies the flashover characteristics ofspacer in SF6 stressed by fast rising oscillating and non-os-cillating impulses in an inhomogeneous electrie field. It isshown that the flashover characteristies are dependent onrise time of impulses and oscillation frequency of impulses.An evident reduetion in the flashover voltage under fast os-cillating impulse of 4 MHz is observed in comparison withthe non-oscillating impulse with the same wavefront time.
