Abstract: A method for operating a drive of a vacuum interrupter in opening mode includes: dividing an opening movement of at least one movable contact into serial phases, an opening phase, and an isolating phase, driven in at least two different velocities. In the opening phase a velocity of the opening movement is lower than in the isolating phase.

Abstract: A three-position disconnector switch includes an earthing contact, a power out contact, a power in contact, a piston, and a threaded rod. A length of the piston is such that in a first switch position an outer surface of a wall of the piston makes an electrical contact between the power out contact and the power in contact. The length of the piston is such that in a second switch position the outer surface of the wall of the piston does not make an electrical contact with either the earthing contact or the power in contact. The length of the piston is such that in a third switch position the outer surface of wall of the piston makes an electrical contact between the earthing contact and the power out contact. The piston includes an inner threaded section configured to engage with the threaded rod.

Abstract: A circuit breaker includes first and second terminals, first and second interrupters, an interconnection part, an actuator, an operating rod, and a lever system. The first terminal is electrically connected to a fixed contact of the first vacuum interrupter. The second terminal is electrically connected to a fixed contact of the second vacuum interrupter. The interconnection part is configured to be in electrical connection with a movable contact of the first vacuum interrupter and the interconnection part is configured to be in electrical connection with a movable contact of the second vacuum interrupter. The interconnection part is configured to provide a current path between the movable contacts. In a transition from an open state to the closed state, the actuator is configured to move the operating rod to move the second end of the first non-linear lever arm and the second end of the second non-linear lever arm.
