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.

使用真空开关投切并联无功补偿装置，在分组投入并联电容器时，串联合适的限流电抗，合闸涌流可以得到控制；重燃时的过电压值与并补装置补偿容量，重燃发生时刻和燃弧时间有关，电容器进线端的三星接法避雷器可以抑制其过电压；切并联电抗器时会产生较高的截流过电压，金属氧化物避雷器可以使本文中所建系统的截流过电压得到限制，并联无功补偿装置可以正常切合。
