摘要
研究了SF_6气体中绝缘子表面具有固定金属导电微粒时,在不同短波头冲击电压作用下的闪络特性,同时研究了电晕起始电压和SF_6气压对闪络电压的影响。研究表明,极不均匀场中SF_6绝缘固体介质表面在陡波作用下的闪络特性不同于气体间隙,其原因可能是位移电流的作用。
This paper deals with the flashover characteristics of spacers with fixed conducting particles in SF6 stressed by steep - fronted impluses of different front times. The effect of the corona inception voltage and the gas pressure on the surface fla -shover voltage is also studied. The results show that the flashover behaviors along the surface of spacers in SF6 in highly non - uniform electric field are different from those of the gas gap,which may be due to the displacement current.
