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.

Abstract: A switching device including: one or more fixed contacts and one or more movable contacts, each movable contact being reversibly movable between an opening position, at which the movable contact is decoupled from a corresponding fixed contact, and a closing position, at which the movable contact is coupled with the corresponding fixed contact; an electromagnetic actuator adapted to actuate the movable contacts between the opening and closing positions, the electromagnetic actuator including a fixed yoke and a movable armature operatively associated with the fixed yoke to form a magnetic circuit, the movable armature being reversibly movable between a first position, which corresponds to the opening position of the movable contacts, and a second position, which corresponds to the closing position of the movable contacts; and a kinematic chain to operatively connect the movable armature with the movable contacts, wherein the electromagnetic actuator includes a first excitation coil and a second excitation coil wound around the fixed yoke. The switching device further include a first power drive circuit adapted to provide a first excitation current to the first excitation coil and a second power drive circuit adapted to provide a second excitation current to the second excitation coil; the first and second power drive circuits are galvanically separated one from another and capable of operating independently one from another.

Abstract: An electrical connection for medium and high voltage switchgears includes an electrical terminal of a switchgear. An electrical contacting surface of the electrical terminal as first current carrying part is electrically connected with a contacting surface of an external electrical connector part as second current carrying part via a connecting system. The connecting system includes a stretch-bolt function, which is integrated in one of the current carrying parts. The stretch bolt function is provided with a male screw thread at the extending end, which is configured to be screwed into a female threaded hole of the second current carrying part.

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.
