导电微粒对SF_6中支撑绝缘子冲击闪络性能的影响

Influence of Conductive Particles on the Impulse Flashover of Disc Spacer in Compressed SF_6

本文介绍了光滑和波纹状盘式支撑绝缘子表面有固定导电微粒时对冲击闪络的影响,比较了微粒的长度、位置、方向以及坐向的影响。研究不仅找到了对导电微粒敏感的区域,也证实了电场切线分量对闪络的重要作用。

This paper presents the influences of two kinds of shape with fixed conductive particle on the impulse flashover of disc spacer. The influences have been irvestigated and comparated with different positions, directions, locations and lengths of particles. The sensitive area for conductive practicle also the importance of field tangtial component has been obtained.
