Definitions

  • the invention relates to a permanent magnetic drive for an electrical Switchgear.
  • Such an electromagnetic drive is for example from DE 197 09 089 A1 known.
  • This permanent magnetic drive has a closed, ring-shaped yoke, which is composed of laminated sheets and two spaced apart has longitudinal webs on which two pole shoes facing each other are molded.
  • An anchor runs parallel to the longitudinal webs and between the free ones
  • the ends of the pole pieces and the armature are two permanent magnets.
  • coils are arranged to the permanent magnets, and depending on the control of the The armature is moved from one position to a second position in the coils Magnetic fields are generated in the yoke by the coils, which with the permanent magnetic fields work together to create a back and forth motion.
  • the anchor has two extensions on the end that run in the crossbars of the yoke are; one of the extensions passes through the adjacent crosspiece and is connected to the movable contact stem of a vacuum switch connected.
  • the width varies in that more parallel to the individual lamella sheets on both sides Slat plates are attached.
  • disadvantageously large and heavy actuators result from the bottom the increased number of lamella sheets.
  • the object of the invention is the permanent magnetic drive of the aforementioned Way to improve so that it can also handle larger rated short-circuit breaking currents can be used without changing the width and thus increase the weight significantly.
  • a second permanent magnet arrangement with a movable one Part provided, wherein the movable part is connected to the anchor, so that by the second permanent magnet arrangement of the armature in the direction of switching on is moved and acted upon.
  • FIG. 1 shows a view of a permanent magnetic drive 10.
  • This permanent Magnetic drive 10 has a yoke 11 closed as a ring, which is made of Lamella sheets is composed, the lamella sheets perpendicular to the plane of the drawing are piled up.
  • the yoke 11 comprises two mutually parallel ones Longitudinal webs 12 and 13 and transverse webs 14 and 15 running perpendicularly thereto in the central region of the longitudinal webs 12 and 13 project towards one another Pole shoes 16 and 17 formed on each other at a distance defined below end up.
  • An anchor 18 is displaceable perpendicular to the transverse webs 14 and 15 and in the central axis thereof arranged, which can be designed, for example, as in DE 197 09 089 A1.
  • This anchor 18 is via anchor guide elements 19 and 20, reach through the guide elements 21 and 22 in the crossbars 14 and 15, in the magnetic yoke 11 out.
  • Coils 23, 24 are located between the crossbars 14 and 15 and the pole pieces 16, 17, respectively used. In the intermediate area between the anchor 18 and the free inner ends the pole pieces 16 and 17 permanent magnets 25 and 26 are used, which with the coils 23 and 24 cooperate in a certain way.
  • FIG. 2 shows the switch-on position:
  • the switch 18 is in the off position on the crossbar 14, which is the contact stem is opposite, whereas in the switched-on position the armature 18 against the crossbar 15 adjacent to the switching device bears.
  • Such a permanent magnetic drive is for a certain rated short-circuit breaking current customized; higher switching currents are to be switched greater forces must be exerted. For this it is necessary to double-sided to the Yoke to accommodate more lamella sheets, with the lamella sheets perpendicular to Drawing layer can be stacked.
  • a second permanent magnet arrangement is used to improve and simplify the drive 27 is provided, which has a housing 28 which serves as a yoke housing serves and is made of magnetic material.
  • the housing 28 has two recesses 29 and 30, in which permanent magnets 31 and 32 are inserted; the permanent magnets can also be ring-shaped, the depression 29, 30 can be a ring recess.
  • the housing 28 is with the guide pin 19th firmly connected and between the permanent magnets 31 and 32 and the outer surface the crossbar 14 there is no further additional component.
  • the force generated by the contact pressure springs depends on the rated short-circuit breaking current, it is with the second permanent magnet arrangement possible, for example for a rated short-circuit breaking current of 31.5 kA rated actuator without additional Slat plates can also be used for a short-circuit breaking current of 40 kA.
  • a corresponding setting thread can be located between the guide pin 19 and the housing 28 be provided so that the air gap, which is in the position shown in FIG. 2 between the housing 28 and the upper crossbar 14 results, can be varied can.
  • Such setting elements are threaded spindles with nuts and lock nuts, the mother may be the housing 28 at the same time, not known.
  • the permanent magnets 31, 32 in motion are and in the event of a switch-off action also bumping against the upper one Open crossbar 14, it is useful to use a solution according to FIG. 3.
  • a U-shaped holding element 35 provided or attached, the legs 36, 37 of the crossbar 14th project away.
  • the holding element can also be designed annular.
  • a permanent magnet 38 is used, the mechanical Connections, for example a nut 39 against the bottom of the U-shaped holding element 35 is screwed.
  • the permanent magnet 38 can also be annular be executed.
  • the permanent magnet 38 With the guide pin 19 via a connecting pin 41 is a Inference part 40 connected, which is movable according to the double arrow direction P. is, so that in the position shown in Fig. 3, the permanent magnet 38 none Has effect, whereas when the yoke part 40 strikes the free ends the legs 36 and 37 give a corresponding magnetic flux distribution, the same Way helps to support the start-up movement and the static holding force to increase.
  • the permanent magnet 38 is immobile and arranged in a fixed position; as a result, it is not an impact load or only one subject to slightly impacting stress for the life of the permanent magnet also has advantages.
