摘要

利用合成回路对外屏蔽罩式杯状纵磁触头结构的35kV真空灭弧室进行了研究.不同开距下的试验结果表明

35kV真空灭弧室存在着一个最佳的开距范围

在此范围内

弧后重燃次数较少

且弧后耐压水平较高.对试验结果进行了分析后指出了缩小目前国内35kV电压等级真空断路器的灭弧室开距的必要性.

Abstract

A synthetic circuit is used in tests to measure and research 35kV exposed shield vacu-um interrupters with cupped axial magnetic field type electrodes. The experimental results under vari-ous separation showed that there is a limitation of the best separation for 35kV vacuum interrupters. In this range

the probability of reignition is lower and the post zero withstand-voltage is higher. This pa-per analyzes the experimental results and points out that it is necessary to reduce the electrode separa-tion of domestic vacuum interrupters.
