The proposed high-speed synchronous vacuum switch contains a vacuum arc chute, a high-speed combined actuator, a control unit, and voltage and current transformers that are inserted in the power circuit of the switch. The actuator contains an induction dynamic mechanism with a rod that is coupled with a ferromagnetic disk. The disk is arranged between two permanent magnets with demagnetizing coils, which are installed in the casing of the switch. The permanent magnets generate additional traction force acting on the disk and, via the rod, on the actuator.
