摘要
研究了灭弧室内工作表面吸气与放气的动态过程,分析了触头材料的含气量与电弧输入能量对动态真空度的影响,讨论了开发更大电流等级真空断路器对触头材料的要求。
One of the fundamental conditions of vacuum interrupters is their in-ner vacuum pressure. This paper investigated the dynamic process of gas absorption and desorption of the working surfaces, analysed the effects of gas content and en-ergy input of the contacts on the dynamic vacuum pressure and discussed the de-mands in respect of contact material for the development of vacuum circuit breakers with higher breaking capacity.
