Definitions

  • the invention relates to a permanent magnetic drive for an electrical switching device.
  • Such an electromagnetic drive is for example from the DE 197 09 089 A1 known.
  • This permanent magnetic drive has a closed, annular yoke, which is composed of laminated sheets and has two mutually spaced longitudinal webs on which alsfactzu classified two pole pieces are formed.
  • An armature runs parallel to the longitudinal webs and there are two permanent magnets between the free ends of the pole shoes and the armature. Coils are arranged on both sides of the permanent magnets and, depending on the control of the coils, the armature is moved from a position to a second position in which magnetic fields are generated in the yoke by the coils, which interact with the permanent magnetic fields to move back and forth to create.
  • the armature has two extensions on the front side, which are guided in the transverse webs of the yoke; one of the extensions passes through the adjacent crosspiece and is connected to the movable contact stem of a vacuum switch.
  • bistable actuator drive for different rated short-circuit breaking currents to be adjusted, then the width is varied, are mounted on both sides in parallel to the other lamellar more laminations.
  • large rated short-circuit breaking currents however, unfavorably large and heavy akutatoren arise due to the increased number of lamella plates.
  • the object of the invention is to further improve the permanent magnetic drive of the type mentioned so that it can also be used for larger design Kurzappelausschaltströme without changing the width and thus to increase the weight significantly.
  • a second permanent magnet arrangement is provided with a movable part according to the invention, wherein the movable part is connected to the armature, so that is moved and acted upon by the second permanent magnet arrangement of the armature in the direction of switching.
  • the Fig. 1 shows a view of a permanent magnetic drive 10.
  • This permanent magnetic drive 10 has a closed ring as a yoke 11, which consists of Laminated sheets is composed, the laminations are stacked perpendicular to the plane.
  • the yoke 11 comprises two mutually parallel longitudinal webs 12 and 13 and perpendicular thereto transverse webs 14 and 15. Approximately in the central region of the longitudinal webs 12 and 13 projecting pole pieces 16 and 17 are formed on each other, which end at a distance defined below from each other.
  • an armature 18 Perpendicular to the transverse webs 14 and 15 and in the central axis of an armature 18 is slidably disposed, which may for example be formed as in the DE 197 09 089 A1 described.
  • This armature 18 is guided in the magnetic yoke 11 via armature guide elements 19 and 20, which engage in the guide elements 21 and 22 in the transverse webs 14 and 15.
  • At the guide extension 20 includes the movable contact stem of a vacuum switch, as has become known from the above-mentioned German patent application.
  • Such a permanent magnetic drive is adapted for a particular rated short-circuit breaking current; should higher breaking currents can be switched, larger forces are applied. For this it is necessary to both sides of the Yoke more lamellae accommodate, with the lamellar plates are stacked perpendicular to the drawing plane.
  • a second permanent magnet assembly 27 which has a housing 28 which serves as a yoke housing and is made of magnetic material.
  • the housing 28 has two recesses 29 and 30, in which permanent magnets 31 and 32 are used; the permanent magnets may also be annular, wherein the recess 29, 30 may be an annular recess.
  • the housing 28 is fixedly connected to the guide pin 19 and between the permanent magnets 31 and 32 and the outer surface of the transverse web 14 is no further additional component.
  • the force to be generated by the contact pressure springs depends on the rated short-circuit breaking current, it is possible with the second permanent magnet arrangement to provide an actuator, for example for a rated short-circuit breaking current of 31.5 kA, without additional laminations even for a short-circuit breaking current of 40 kA to use.
  • a corresponding adjusting thread Between the guide pin 19 and the housing 28 may be provided a corresponding adjusting thread, so that the air gap, which in the position according to Fig. 2 between the housing 28 and the upper transverse web 14 results, can be varied thereby.
  • adjustment elements are threaded spindles with nut and lock nut, wherein the nut may be the housing 28 at the same time, not known.
  • a U-shaped holding element 35 is provided or fixed, the legs 36, 37 projecting from the crossbar 14 away.
  • the holding element can also be designed annular.
  • a permanent magnet 38 is inserted, which is screwed by means of mechanical connections, such as a nut 39 against the bottom of the U-shaped support member 35.
  • the permanent magnet 38 may also be designed annular.
  • a yoke 40 is connected, which is movable according to the double arrow direction P, so that in the in Fig. 3 shown position of the permanent magnet 38 has no effect, whereas upon impact of the yoke 40 on the free ends of the legs 36 and 37 results in a corresponding magnetic flux distribution, which in the same way helps to support the switch-on and increase the static holding force.
  • the permanent magnet 38 is immovable and stationary; As a result, it is not subject to any impact load or only to a slightly impacting load, which also has advantages for the life of the permanent magnet.
