摘要
通过对绝缘外壳的空气击穿特性、固体介质沿面闪络特性的分析,给出了真空开关管绝缘外壳的设计要点,即绝缘外壳的最小高度是由冲击电压决定的,而爬电距离是由工作电压及环境条件决定的。绝缘外壳要同时满足这两方面的要求。
Having analyzed the features shown by air breakdown an injulating outer hard, and that cause solid medium to produce a creeping overflash, the paper presents points for a vacuum switch outer hard to be designed, namely that the minimum height of the outer hard is determined by an impulse voltage, however the creeping distance is determined by a working voltage and environmental conditions. Therefore, the injulating outer hard must meet the needs simultaneously, of the both concerned.
