摘要： A switching apparatus comprising one or more electric poles.
For each electric pole, the switching apparatus comprises a first pole terminal, a second pole terminal and a ground terminal. In operation, the first pole terminal can be electrically coupled to a first conductor of an electric line, the second pole terminal can be electrically coupled to a second conductor of said electric line and the ground terminal can be electrically coupled to a grounding conductor.
For each electric pole, the switching apparatus comprises a plurality of fixed contacts spaced apart one from another. Such a plurality of fixed contacts comprises a first fixed contact electrically connected to the first pole terminal, a second fixed contact electrically connected to the second pole terminal, a third fixed contact electrically connected to the ground terminal and a fourth fixed contact electrically connectable with the second fixed contact.
For each electric pole, the switching apparatus further comprises a movable contact, which is reversibly movable about a corresponding rotation axis according to opposite first and second rotation directions, so that said movable contact can be coupled to or uncoupled from one or more of the above-mentioned fixed contacts, and a vacuum interrupter comprising a vacuum chamber, in which a fixed arc contact and a movable arc contact are enclosed and can be coupled or decoupled.
For each electric pole, the switching apparatus further comprises a motion transmission mechanism operatively coupled to the movable arc contact of said vacuum interrupter. 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.

摘要： Die Erfindung betrifft eine Restlast-Trenntechnik zur Trennung einer elektrischen Verbindung an einer Einspeisestelle zu einem Fahrstrom-Versorgungsleiter eines elektrischen Verkehrsmittels. Die Restlast-Trenntechnik umfasst einen Rotationsschaltkörper und einen zugehörigen Restlast-Trennschalter (1). Der Restlast-Trennschalter (1) ist zur Trennung einer elektrischen Verbindung zu einem Fahrstrom-Versorgungsleiter (8) für ein Verkehrsmittel (7) ausgebildet. Er umfasst einen Zuleitungs-Anschluss (20), einen Ableitungs-Anschluss (21) und mindestens eine Schaltvorrichtung (22). Der erfindungsgemäße Rotationsschaltkörper weist ein mehrteiliges isolierendes Gehäuse (60) auf, das eine erste Halbschale (73), eine zweite Halbschale (74) und eine Innenhülse (72) umfasst. Der Rotationsschaltkörper (23) weist ferner mindestens ein Kontaktschwert (24, 25, 26, 27) auf und das mindestens eine Kontaktschwert (24, 25, 26, 27) hat eine zentrale Ausnehmung, durch die sich das Gehäuse (60) erstreckt. Der Gehäuseaufbau erzeugt besonders lange und somit gegen Durchschlag gesicherte Kriechstrecken, sodass der Rotationsschaltkörper und damit der Restlast-Trennschalter besonders kompakt ausführbar sind. So wird eine Montage direkt an einem Fahrstrom-Versorgungsleiter bspw. einer Fahrschiene einer S-Bahn ermöglicht.

摘要： The invention relates to a device for operating a switch having an operating lever for moving the switch between the open and closed position and an operating pin arranged to a moving part of the switch, wherein the device comprises:
- a primary shaft;
- a secondary shaft arranged coaxially with the primary shaft, wherein the secondary shaft has a D-shaft portion arranged for locking and releasing the operating lever of the switch by rotating the secondary shaft;
- a coupling arranged between the primary shaft and the secondary shaft, wherein the coupling has rotational play to allow for a relative axial rotation of the primary and secondary shafts between a first rotational position and a second rotational position;
- a spring for urging the primary shaft in a first rotational direction;
- a control lever extending in a radial direction from the primary shaft for contact with the operating pin of the contact such that the operating pin can move the primary shaft in a second rotational direction;
- a latch having a disengage lever extending in a radial direction from the primary shaft and a roller movable into the path of the disengage lever to limit rotation of the primary shaft in the first rotational direction; and
- a reset lever extending in a radial direction from the secondary shaft.

摘要： The present invention relates to a drive for a low, medium or high voltage switch, comprising: a pushrod (10); a sun cogwheel (30); at least one planetary cogwheel (40); a carrier (50); a cogwheel ring (60); and a carrier locking device (200). An axis of the pushrod is coaxial with an axis of the sun cogwheel, and a rotation of the sun cogwheel is configured to move the pushrod along the axis of the pushrod. An axis of the carrier is coaxial with the axis of the sun cogwheel, and the carrier comprises at least one latching feature (52). An axis of the cogwheel ring is coaxial with the axis of the sun cogwheel. The at least one planetary cogwheel is located between the sun cogwheel and the cogwheel ring, wherein each planetary cogwheel of the at least one planetary cogwheel is connected to the carrier such that when the carrier rotates about the axis of the sun cogwheel a centre axis of each planetary cogwheel rotates with the carrier, and wherein each planetary cogwheel is configured to rotate about its own centre axis. The carrier locking device is configured to engage with one latching feature of the at least one latching feature of the carrier to stop the carrier from rotating, and the carrier locking device is configured to disengage from the at least one latching feature of the carrier to permit the carrier to rotate. Initiation of a first switching action comprises a disengagement of the carrier locking device from a latching feature of the at least one latching feature of the carrier. In the first switching action a rotation of the carrier about the axis of the sun cogwheel in a first rotational direction is configured to rotate the sun cogwheel in the first rotational direction to move the pushrod along the axis of the pushrod in a first direction.

摘要： An operation mechanism for a dual-power automatic transfer switch and a dual-power automatic transfer switch. The operation mechanism includes: a frame; a rotating disk, rotatably mounted to the frame; a first elastic member, wherein one end of the first elastic member is configured to abut against the rotating disk, and the other end of the first elastic member is mounted to the frame; a driving disk, configured to rotate in cooperation with the rotating disk when the rotating disk rotates; a driving rod, mounted on the driving disk and configured to rotate together with the driving disk and connected with a movable contact bracket, wherein at the dual-off position of the dual-power automatic transfer switch, when the rotating disk rotates in a first direction, the first elastic member deforms to store energy, and after the rotating disk rotates by a predetermined angle, the rotating disk abuts against the driving disk so that the driving disk also rotates in the first direction, then the first elastic member passes through a "dead point", and the rotating disk and the driving disk continue to rotate in the first direction under an action of the first elastic member, so that the driving rod rotates in the first direction and drive the movable contact bracket to rotate, so as to realize a switching of the dual-power automatic transfer switch from the dual-off position to the first power-on position.
