摘要
测试和研究了纵磁灭弧室中真空电弧弧后电流的变化与开断电流和电极开距之间的规律,得出了使弧后电流快速上升的转折电流,它表征了燃弧期间开始出现阳极斑点.
This paper measures and investigates the laws on the relations be-tween the post arc currents and the breaking current, the electrodes gap length in the vacuum interrupter with an axial magnetic field. It is obtained that the turning current after which the post arc current increases rapidly is the result of the appear-ance of anode spot during arcing duration.
