一种使用真空灭弧室的分接开关控制系统。控制系统具有用于监视真空断续器的装置，以检测这种断续器的任何故障，从而防止抽头变换器的进一步操作。如果分接开关无法打开断续器，则分接开关电机反转，使开关返回到起始位置并锁定开关。如果断续器在分接变换开始时打开，则分接变换器反转，使分接变换器返回到起始位置，然后锁定分接变换器。在另一个实施例中，如果在开始抽头变换之后中断器未能闭合，则抽头变换完成并且变换器被锁定在该位置。
A control system for a tap changer using a vacuum interrupter. The control system has provisions for monitoring the vacuum interrupter to detect any failure of such interrupter and thus prevent further operation of the tap changer. Should the interrupter fail to open on a tap change, the tap changer motor is reversed returning the changer to the starting position and locking the changer. Should the interrupter be open at the start of a tap change, the tap changer is reversed returning the tap changer to the starting position and then locking the tap changer. In another embodiment, should the interrupter fail to close after a tap change has been initiated, the tap change is completed and the changer locked in that position.
