Abstract: A circuit breaker includes first and second terminals, first and second vacuum interrupters, an interconnection part, an actuator, an operating rod, and a lever system. The first terminal is 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 associated with a movable contact of the first and second vacuum interrupters when the circuit breaker is in a closed state. A first end of a first lever arm is coupled to the movable contact, and a second end is coupled to the operating rod. When transitioning from an open to a closed state, the actuator moves the operating rod to move the second end of the first lever arm and the second end of the second lever arm.

Abstract: A switching apparatus including one or more electric poles. For each electric pole, the switching apparatus includes a first pole terminal, a second pole terminal, a ground terminal, and a plurality of fixed contacts spaced apart one from another. For each electric pole, the switching apparatus further includes a movable contact and a vacuum interrupter. The movable contact is reversibly movable about a corresponding rotation axis. The vacuum interrupter includes a movable arc contact reversibly movable along a corresponding translation axis. For each electric pole, the switching apparatus further includes a motion transmission mechanism operatively coupled to a contact shaft solidly coupled to the movable arc contact. The motion transmission mechanism is actuatable by the movable contact to cause a movement of said movable arc contact along said translation axis, when said movable contact moves about said rotation axis.

Abstract: A medium voltage switching pole includes: a fixed contact of a vacuum interrupter; a movable contact of the vacuum interrupter; a piston; at least one electrical contact; a first terminal; and a second terminal. The fixed contact is fixedly connected to the first terminal. The movable contact is fixedly connected to the piston. The piston moves within the second terminal along an axis. The at least one electrical contact makes an electrical connection between the piston and the second terminal. An outer surface of the piston and an inner surface of the second terminal are arranged such that: when in an open configuration the fixed contact and movable contact are separated, at least one first radial line perpendicular to the axis extends through locations of the at least one electrical contact, and a first distance along the at least one first radial line extends from the outer surface.

Abstract: A medium voltage circuit breaker switching pole includes: a fixed contact of a vacuum interrupter; a movable contact of the interrupter; and a threaded drive element. The movable contact is configured to move along a longitudinal axis of the interrupter. A centre axis of the drive element is parallel to the longitudinal axis of the interrupter. When in an open configuration the fixed contact and movable contact are separated from one another. When in a closed configuration the fixed contact and movable contact are in contact with one another. Rotation of the drive element about its centre axis in a first direction is configured to transition the switching pole from the open configuration to the closed configuration. Rotation of the drive element about its centre axis in a second direction counter to the first direction is configured to transition the switching pole from the closed configuration to the open configuration.
