  • Electromagnetically actuated switching device
  • the invention relates to an electromagnetically actuated switching device with - at least one vacuum interrupter
  • a drive housing made of sheet metal or plastic which receives the drive magnet, an insulating chamber which holds the at least one vacuum interrupter and is connected to the drive housing,
  • a device accommodated in the drive housing for latching the armature of the drive magnet in its tightened position and for releasing the latching the device being a latching lever designed as an armature in a first release magnet and a latching lever biasing the latching lever into its latching position Feather shows.
  • a switching device with these features is known from DE-A-35 24 524.
  • the device for latching the armature of the drive magnet and for releasing the latch has the task of converting the switching device into its switch-on position by only briefly supplying energy, so that no energy for holding the drive magnet in the energized state during the entire switch-on period Position is needed. Switching off is also carried out by only briefly supplying energy, in this case to the trigger magnet.
  • the release magnet can be used by everyone within the space available within the drive housing occurring currents and voltages can be designed. It is therefore possible to trigger the switching device by means of very different current sources or circuits.
  • the device according to the aforementioned publication there is the possibility in the device according to the aforementioned publication to switch off the switching device by hand by pulling an actuating rod provided for this purpose. If switching devices of the type considered here are used where absolute security of the remote-controlled triggering is important, then the possibility provided for the switching device according to the aforementioned publication is not sufficient to actuate the latching lever by hand. However, it could be considered to provide the trigger magnet with an additional winding, which could then be part of a further, independent trigger circuit. Obviously, this would considerably increase the trigger magnet.
  • the object of the invention is to ensure the possibility of remote-controlled triggering of the switching device with the greatest possible security.
  • This object is achieved according to the invention in that a second trigger magnet with an armature, which is not electrically connected to the first trigger magnet, is arranged on the drive housing and that - the armature is connected in an articulated manner to a trigger lever which interacts with the latching lever.
  • the second (additional) tripping magnet ensures that damage to the tripping winding of the first tripping magnet by any cause remains limited to the first tripping magnet.
  • the second trigger magnet then forms an independent, full-fledged possibility of triggering.
  • the release lever offers the possibility of bridging a certain distance between the two release magnets. The spatial separation achieved in this way between the first and the second release magnet increases the desired safety.
  • the second release magnet is attached to the outside of a wall of the drive housing, that the release lever projects into the interior of the drive housing through an opening arranged in the wall of the drive housing and that a bearing block is arranged as a pivot bearing for the release lever near the latching lever.
  • a design suitable for the second trigger magnet is a plunger magnet. This can be expediently aligned with its longitudinal axis parallel to the wall of the drive housing provided for fastening the second release magnet.
  • FIG. 1 shows a sectional view of a switching device with vacuum interrupters.
  • FIG. 2 shows part of a drive housing of the switching device according to FIG. 1 with a first and a second release magnet.
  • the switching device shown in FIG. 1 is, for example, a three-pole contactor for the medium-voltage range.
  • the contactor 1 has a drive box 2 made of sheet steel and an insulating material chamber 3 for accommodating one or more vacuum interrupters 4, which is provided with dividing walls in the case of a multi-pole version.
  • the drive housing 2 and the insulating material chamber 3 are connected to one another.
  • In the drive housing 2 there is a drive magnet 5, the armature of which is part of a rocker-like drive lever 6, which is connected to a movable connecting bolt 7 of the vacuum interrupter 4.
  • the circuit to be switched by the contactor 1 is connected to the connection devices 10.
  • a second trigger magnet 15, indicated by dashed lines in FIG. 1, is essential for the invention, which is explained in more detail below with reference to FIG.
  • FIG. 2 shows part of the drive housing 2 in a position rotated by 90 ° with respect to FIG. 1.
  • the first release magnet 12 arranged in the interior 16 of the drive housing 2 and a bearing block 17 for the one piece with a can be seen in more detail
  • Anchor-trained latch lever 13 which is provided with a roller 20.
  • the roller 20 engages to latch the contactor 1 in its switched-on position behind a nose 21 on the drive lever 6 of the vacuum contactor 1 (FIG. 1; see also FIG. 2 of DE-A-35 24 524).
  • the first tripping magnet 12 has a winding which is adapted to a suitable tripping circuit. Therefore, if the contactor 1 has been switched on by excitation of the drive magnet 5 (FIG. 1), the aforementioned roller 20 of the latching lever 13 falls behind the nose 21 of the drive lever 6 and thus holds the contactor 1 in its switched-on position for any length of time. To switch off, the trigger magnet 12 is also only required to be briefly excited, as a result of which the roller 20 is moved away from the nose 21 of the drive lever 6 against the action of a return spring 18. This now returns to its switch-off position under the influence of the switch-off spring 11, which means that the Devices 10 connected consumer circuit is interrupted.
  • the second trigger magnet 15 is available, which is fastened to a wall 22 of the drive housing 2.
  • the second release magnet 15 is located on the outside of the drive housing 2 and is oriented with its longitudinal axis parallel to the wall 22.
  • the second tripping magnet 15 is designed as a plunger armature magnet, the plunger armature 23 shown executing a movement in the direction of an arrow 24 when the tripping magnet 15 is excited.
  • a release lever 26 is articulated to a head piece 25 of the armature 23 and has an elongated, twice cranked shape.
  • a design of a release magnet that is particularly suitable for the intended purpose can be selected. It is also largely ruled out that if one of the tripping magnets is damaged, the other tripping magnet can be affected, because between the two tripping magnets a distance exists and the wall 22 is arranged. The wall 22 largely closes off the drive housing 2, since only a relatively small opening 32 is required for the trigger lever 26 to pass through.

Abstract

Un coupe-circuit à vide (1) encliquetable est muni de deux électro-aimants de déclenchement (12, 15) indépendants. Le premier électro-aimant de déclenchement (12) est inséré conjointement avec un levier d'encliquetage (13) dans l'espace intérieur d'un boîtier de commande (12), alors que le second électro-aimant de déclenchement (15) se trouve contre une paroi (22), côté extérieur du boîtier de commande (2). Un levier de déclenchement (26) faisant saillie à l'intérieur du boîtier de commande (2), relie le second électro-aimant de déclenchement au levier d'encliquetage (13). Les deux électro-aimants de déclenchement (12, 15) ne sont pas reliés électriquement l'un à l'autre et assurent un déclenchement indépendant et fiable du coupe-circuit (1).
