Definitions

  • the invention relates to an electromagnetic switching device, in particular a circuit breaker, with a Coil, one in this sliding anchor and one of this actuatable magnetic tappet, with a moving contact interacting with the striker and with an unlatching device which interacts with it.
  • a switching device is off, for example DE 19 04 731 A known.
  • a switching device referred to as a small auto switch for example known from DE 19 04 731 A has one Moving contact, the one in the closing contact Position is blocked by a latch.
  • the releasing the latching and opening of the moving contact happens by means of a magnetic trigger, the plunger of which is initially on the Latch strikes and in the further course of movement over one Lever or extension of the latch indirectly on acts on the moving contact.
  • the moving contact is additional loaded by a spring towards its open position.
  • this spring is delayed one that immediately after releasing the latch, i.e. even before the moving contact by the spring in it open position was shifted, operated by the plunger Boom of the latch hits the moving contact and with one Force applied towards its open position.
  • a disadvantage of thus delayed and braked opening of the moving contact especially the increased sparking between the moving contact and that interacting with it, electrically fixed contact connected to the coil of the magnetic release.
  • the invention has for its object an electromagnetic Switchgear with a magnetic release to indicate which especially a moving contact secured by a latch opens quickly and reliably.
  • an electromagnetic Switchgear with the features of claim 1.
  • the switching device has a magnetic release with one in one Coil movable plunger anchor and one actuated by it Impact plunger to open one by one Unlatching device provided secured moving contact is.
  • the plunger is without direct Interaction with the unlatching device of the moving contact can be operated immediately.
  • To open the unlatching device is one that does not interact directly with the moving contact Locking anchor part provided.
  • This latch anchor part can be part of the same anchor that Impact ram actuated, preferably rigidly with the ram is connected, or part of a second also as Diving anchor be trained anchor. In any case it is Process of unlatching from the process of opening the moving contact decoupled.
  • the opening of the moving contact can coincide with the or even start before unlatching. In the latter case, i.e. when the moving contact opens in advance preferably its elastic design or elastic Suspension used. It is therefore possible that the and unrestrained acting on the moving contact
  • the plunger has already removed it from the fixed contact, if the unlatching device is not or not yet is fully open.
  • the striker is involved enough high energy on the moving contact to its Prevent spring back to fixed contact.
  • the unlatching process preferably occurs in parallel with the opening of the moving contact.
  • the magnetic release has two separate ones that can be moved within a single trip coil Diving anchors on, the first of which with the Impact plunger is connected and the second to the locking anchor part is connected or has this.
  • the plunger and the locking anchor part protrude preferably on the same side from the coil of the magnetic trigger.
  • the the latch anchor part having a second magnet armature is hollow and in this case is penetrated by the punch.
  • the direction of actuation the ram is the direction of actuation opposite anchor.
  • Anchors are preferably one with both anchors on both sides cooperating disc-shaped core within the coil arranged.
  • the core is preferably off-center, namely for Locking anchor part and thus to the moving contact to be actuated offset, arranged in the coil.
  • the two anchors can be carried out in a particularly simple manner a single compression spring clamped between them in the coil, which has an opening in an optionally in the coil penetrated existing core, be biased.
  • a single compression spring clamped between them in the coil which has an opening in an optionally in the coil penetrated existing core, be biased.
  • the spring characteristics of the two compression springs are different can be. This is a further decoupling of the two anchors and thus the opening process of the moving contact on the one hand and the unlatching process on the other given.
  • the advantage of the invention is in particular that by decoupling the opening of a moving contact from the Unlatching the moving contact at least in the initial phase the opening movement when a magnetic release is activated a particularly fast and reliable switching behavior is.
  • the magnetic release 1 essentially consists of one another a coil 5 mounted on a sleeve 4, a magnetic yoke 6, a disc-shaped, in the sleeve 4 within the Coil 5 held core 7, one with a striker 8th connected first anchor 9 and a second anchor 10. Die Anchors 9,10 are mainly or exclusively by means of Sleeve 4 out.
  • anchors 9, 10 are used for guiding Bearing 20 is provided, which are shown only in a hint Housing shells of the switching device are formed and with sufficient guidance of the armature 9, 10 in the sleeve 4, too can only have the function of attacks.
  • an exclusive management of the Anchors 9, 10 can be provided in the bearings 20.
  • a latching point 12 of the unlatching device 3 is in the form of a recess on a pawl 13 in engagement with a Verklinkungsankerteil 14, which in illustrated embodiment by an outside of Coil 5 lying edge of the second armature 10 is formed.
  • magnetic trigger 1 When magnetic trigger 1 responds, i.e. with overcurrent in the coil 5, especially in the event of a short circuit, becomes the first armature 9 in a first actuation direction R1 and the second Armature 10 in an opposite actuation direction R2 pulled towards the core 7.
  • the core 7 is slightly off-center, offset to the moving contact 2, arranged in the coil 5, with a first air gap 15 between the first anchor 9 and the core 7 is wider than a second air gap 16 between the second anchor 10 and the core 7. This corresponds a longer actuation path of the ram 8 in comparison to the actuation path of the second armature 10.
  • the core 7 can also in a different position, in particular in the center, arranged in the coil 5 his.
  • the second anchor 10 with the latching anchor part 14 is already so far in the actuation direction R2 in the coil 5 pulled in that the pawl 13 released is. This does not necessarily mean that the unlatching device 3 is already completely open.
  • the first anchor 9 is also already in the actuating direction R1 slightly shifted towards the core 7, so that the impact ram 8 past the pawl 13 on the rotatable on an axis 17 stored moving contact 2 to move.
  • Each anchor 9, 10 is one separate compression spring 18a, 18b assigned, each on one on the core 7 lying sleeve portion 19 is mounted.
  • the masses of the anchors 9, 10 and Dimensioning the air gaps 15, 16 is the response behavior of the magnetic trigger 1 adjustable within wide limits.
  • FIG. 5 An alternative embodiment of the storage of the anchor 9.10 in FIG. 5 shows the coil 5.
  • Compression spring 18 is provided, which as a coil spring surrounds the ram 8 and how it has an opening 22 of the core 7 penetrates.
  • the movement of the anchors 9, 10 outwards, i.e. against the force of the compression spring 18 is through attacks not shown limited.
