Abstract: A switch for medium voltage applications is provided. The switch comprises a vacuum interrupter having a fixed contact, a movable contact movable in a first direction to and away from the fixed contact between a closed position and an open position, and a drive rod arranged to the movable contact for moving the contact between the closed position and the open position. The switch further comprises a changeover switch having a first terminal body, a second terminal body, an elongated pole body, and an operating rod. The elongate pole body is hinged with a first end to the first terminal body and rotatable between a connected position in which the second end of the pole body is in direct electrical contact with the second terminal body and a disconnected position in which the second end is disconnected from the second terminal body.

Abstract: A changeover switch for medium voltage switchgear is provided. The changeover switch includes a first terminal body, a second terminal body, and two elongate pole bodies. The two elongate pole bodies are arranged parallel to each other and rotatably arranged with first ends on opposite sides of, and in direct contact with the first terminal body around a rotation axis. The two elongate pole bodies are rotatable between an open position and a closed position. The second ends of the two elongate pole bodies are positioned in direct contact with opposite sides of the second terminal body. The changeover switch further includes one or more springs arranged between the two elongate pole bodies to urge the two elongate pole bodies towards each other.

Abstract: A device for operating a switching device, such as a vacuum interrupter, includes an operating axle for operating the switching device; a driving unit for driving the operation axle; a spring element coupled between the driving unit and the operating axle; and a blocking device for blocking rotation of the operating axle.

Abstract: A connector for electrically connecting two panels having switchgear has: two cups having a truncated cone shape for arrangement in a panel, the cups each having a conductor end extending through the tip of the cone and into the cup; an insulating body having two opposite truncated cone shaped outer surfaces each for reception in one of the cups and having a central passage; an electrically conducting element for connecting with the conductor ends extending in the central passage of the insulating body; wherein the insulating body is a molded body having an earth wire molded in; and wherein a coating of an electrical conducting layer is arranged on the earth wire and at least part of the insulating body.

Abstract: A switching installation includes a gas tight housing with at least one wall part. An input conductor disposed in the housing is configured to carry an input voltage. An insulation is arranged around the input conductor so as to insulate the input conductor from the housing. A short-circuit device is changeable from a first condition, in which the insulation is insulating the input conductor from the housing, to a second condition, in which an electrical short circuit connection is created through the insulation between the input conductor and an auxiliary connection. An actuator is coupled to the at least one wall part of the gas tight housing and is configured to actuate the short-circuit device as a result of movement of the wall part caused by a pressure increase in the housing. A threshold device is configured to provide a preset threshold in the actuator.
