摘要

对于真空灭弧室的静态耐压

本文给出了一改进的模型灭弧室和一些相关的实验结果

证明在解决了外绝缘和老炼工艺问题后

10kV等级的真空灭弧室可以改造用于35kV等级

对于动态介质恢复方面

文中分析了均压屏蔽罩与弧后介质恢复的相互作用

给出了35kV/25kA试品的分断试验结果

说明正确设置均压屏蔽罩可使弧后介质恢复满足更高电压等级的要求。

Abstract

For the steady voltage withstanding of vacuum interrupter

an improved model and some relevant experiments are presented in this paper. Under certain conditions

the modified 10kV vacuum interrupter can be used for 35kV grade from this paper. For dynmic voltage withstanding

the interactions sharing shield and post-arc dielectric recoverv are described with the test result of breaking 35kV/25kA.
