Gaoya dianqi, 1979 高压开关柜内部发生电弧短路时,电弧持续燃烧放出的能量可能造成严重破坏,本文综述了开关柜(特别是封闭式开关柜)内发生电弧短路时承受的电动力及其运动规律,柜内气压及温度变化等一系列物理过程,并指出能限制其破坏范围的措施。

Dianci bileiqi, 1990 瞬态过程时的过电压可以引起电动机线圈绝缘的损坏,在直接靠近线圈处装设金属氧化物避雷器,在瞬态过程时,由于阀片有时延,不大有效。此时残压值可能增大到1.5倍起始动作电压值。当火花间隙放电时高频分量足以增大到过电压水平。避雷器从端子箱中取出（根据热稳定的理由）并经过附加电缆接入就会增高过电压每米电缆1kV。将小电容量电容器接入线圈就要求增加安装面积。RC回路降低过电压50％,但不是在所有型式的瞬态过程时都是这样。当无重燃的真空开关时在离线圈很远处装设大电容量的电容器,但是这些电容器不能保证瞬态过程时的保护,
