Locking opening and closing of circuit-breaker is a common fault in power system,the operating methods and skills of insolating the locking circuit-breaker are not same in different main connecting mode.

断路器闭锁分合闸是一种常见的电力设备故障，不同的主接线方式下，隔离闭锁断路器的方法及技巧都不同。

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。

An overhanging part, the apron of the carriage, may be engaged with the feed rod to give continuous feed motion, or with a lead screw for cutting of threads.

一个伸出的部分，支架的围裙，也许以饲料标尺给连续的合闸动作，或者与螺纹切口的丝杠衔接。

After switching on for the first time by controlling on site, when startup current declined,switch off breaker to see if the rotation direction is right,or change phase sequence of motor power cable.

3.12.2 采用现场控制第一次合闸后，待起动电流下降，即行断开，看电动机旋转方向是否正确。如果不正确，可更换电动机动力电缆的相序。

Closed phase angle has important effect on the dynamic behavior of AC contactors including contact bounce , especially.
