【摘要】 与传统的纵向磁场与真空电弧作用的认识不同,提出了在真空灭弧室的触头间加入非均匀分布纵向磁场来抑制真空电弧在大电流下的收缩,从而提高其开断能力这一思路.设计了一种相应的电极结构,并通过计算和实验分析了它的纵向磁场分布及参数的影响.更多还原

【Abstract】 A new concept for improving vacuum interrupter breaking capacity by applying non - uniform distribu-tion axial magnetic field between contacts to restrain the constriction of vacuum arc is introduced. A type of contact con-figuration is designed accordingly, and its magnetic field distribution is studied by calculation and experiment.更多还原
