摘要
根据对SF_6气体极不均匀场间隙异常放电的分析,提出了由三条界限线,即流注击穿线、低概率冲击击穿线和电晕起始线组成的估算间隙低概率冲击击穿电压的方法;击穿电压的计算值和实验测量值的比较表明,计算给出的是稍偏严的结果.
Based on the analysis of the abnormal discharge in non-uniform SF6 gaps, a method for calculating low probability impulse breakdown voltage is presented,which consists of three limiting lines:the streamer breakdown line,low probability impulse breakdown level and the corora initi line in different gas pressure ranges. The calculated value gives a safety margin com-pared with the measured value.
