本文对真空灭弧室的弧后电流现象进行了实验研究。研究了触头材料、电极结构、电极间隙长度等因素与弧后电流的关系。先前已经研究了增加的电弧电流导致弧后电流在某一电弧电流值处快速增加。事实证明，这种现象是由于阳极熔化引起的，轴向磁场电极使阳极上的电流密度降低，从而抑制了阳极熔化。
In this paper, post arc current phenomena in vacuum interrupters are experimentally investigated. This investigation is focused on the relation between post arc current and many factors such as contact materials, electrode structures, and gap length between electrodes. It has been previously investigated that an increasing arc current causes post arc current to increase rapidly at a certain arc current value. It was proved that this phenomenon was caused by melting of the anode, and that the axial magnetic field electrode allowed current density on the anode to decrease, consequently restraining anode melting.
