补偿电容器组同步开关控制器的研制

Development of the Synchronous Circuit Breaker Controller for Compensation Capacitor Banks

介绍了新研制的中压补偿电容器组同步开关控制器的工作原理和基本结构,该控制器将控制和驱动永磁机构,以实现开关的选相合、分闸,从而有效地抑制投切并联电容器组时引起的过电压及涌流。

A new synchronous circuit breaker (SCB) controller for compensation capacitor banks is developed which can be used on the control of a permanent magnetic actuator. The principle of the new controller is described as well as its architecture. The electronic controller together with the VCB driven by a permanent magnetic actuator forms SCB, which can realize the synchronous switching, hence reducing the overvoltage and/or inrush current when switching capacitor banks.
