该文以磁流体动力学为基础建立了三维空气电弧等离子体在外部磁场作用下运动的数学模型，此模型可以预测电弧的重击穿现象，并发现当灭弧室的出口面积为60%时，电弧在3mT磁场的作用下运动时出现了重击穿现象，而当磁场增大到5mT时重击穿现象消失。

When compensating devices are switched by vacuum switches, if they are switched on group, the inrush current can be controlled by inserting suitable current-restrained reactance in-series. Since the restriking overvoltage is pertinent to the capacity of compensating devices and the time of restriking and igniting, the overvoltage can be restrained by arresters with asterism connection at the entrance of the capacitors. Although switching capacitance devices will bring up high interception cross overvoltage, the metal-oxide arrester can limit this overvoltage in the system designed in the thesis, and naturally the compensating devices can operate normally.
