Definitions

  • the invention relates to a switching device according to the preamble of claim 1.
  • Fig. 2 shows a schematic diagram of a switching device such as a DC high-speed switch according to the prior art.
  • the switching device comprises a first and a second rigid connecting part 5, 4 for connecting a circuit to be switched and a movable contact lever 1 which is rotatably mounted about an axis of rotation 6.
  • contact lever 1 By actuating the contact lever 1, contact can be made between the contact plate 2 and a switching contact of the first connection part 5, as a result of which the circuit is closed via the two connection parts 4 and 5 (cf. switching state shown in broken lines in FIG. 2).
  • the contact plate 2 is fastened on the movable contact lever 1, which is electrically connected to the second connection part 4 via a movable connection, such as a flexible band 3.
  • a movable connection such as a flexible band 3.
  • the flexible band 3 there are also current bolts, friction contacts or the like. als- connecting devices between the contact lever and the second connecting part 4 possible.
  • the circuit to be switched is thus closed in the present example according to FIG. 2 via the two connecting parts 4 and 5, the contact lever 1 and the flexible band 3.
  • the contact lever must be designed so that it meets the following mechanical and electrical requirements. From a mechanical point of view, the contact lever should have the lowest possible inertia in order to enable a fast switching process. Due to the high current carrying capacity required, the contact lever cross-section is as large as possible and the specific resistance of the contact lever material is as low as possible as electrical requirements.
  • the function of the current and heat conduction is separated from the function of the contact guidance by arranging the switching contact on the contact lever side on the connecting device.
  • the contact lever takes on purely mechanical management tasks, so that the demands placed on them with regard to the current carrying capacity are eliminated.
  • the contact lever can be manufactured in a lightweight design with low inertia from, for example, electrically non-conductive material.
  • the configuration of the switching device according to the invention enables the use of a relatively long, flexible connecting device such as a flexible band 3, whereby a shape can be realized which has a positive influence on the service life. Furthermore, a high thermal and electrical conductivity is achieved by reducing the contact transition points and the direct connection of the lever-side switching contact to the connecting device.
  • Fig. 1 shows a schematic diagram of the switching device according to the invention
  • FIG. 2 shows a schematic diagram of a switching device according to the prior art
  • FIG. 3 shows a perspective view of an exemplary embodiment according to the invention
  • FIG. 1 shows a basic illustration of a switching device according to the invention.
  • the contact plate 2 is arranged directly on the flexible band 3 serving as a movable connecting device. According to the switching state shown in dash-dotted lines, the current path only extends over the two connecting parts 4 and 5 and the flexible band 3 when the switching device is closed
  • Function of the contact lever 1 is thus limited to the contact guide and it can thus also be made from non-conductive material. In addition, there is no current transfer point between the flexible band 3 and the contact lever.
  • the shape of the flexible band is preferably such that switching operation which is as wear-resistant as possible is made possible. This can be done, for example, by a suitable one Curvature and attachment to the second connector 4 can be achieved.
  • FIG. 3 shows a schematic view of a specific exemplary embodiment of the switching device according to the invention as a DC high-speed switch.
  • a flexible copper strip 3 is connected at its lower end to the second connection part 4 so that it is aligned with the first connection part 5.
  • the copper strip 3 has a pre-curvature, so that mechanical stresses occurring during the switching process are reduced.
  • the copper tape has a slot 8, in which the contact lever 1 is partially fitted.
  • an electrically conductive contact plate 2 is soldered directly onto the copper strip 3 or a suitable connection carrier. The top of the
  • Copper strip 3 is fitted into a recess in the contact lever 1 and is preferably pressure-welded to achieve a solid electrical connection.
  • a pre-contact 7 At the upper end of the contact lever 1 there is a pre-contact 7 which protects the main contact from erosion during operational switching operations and thus increases the service life of the main contact.

Abstract

Ce commutateur sert à établir une connexion électrique entre deux pièces à connecter (4, 5). Les commutateurs classiques comprennent un levier de contact (1) avec un contact commutateur (2). Lorsque le commutateur est fermé, le courant s'écoule à travers le levier de contact (1). Pour obtenir une commutation rapide, l'inertie de masse du levier de contact (3) doit être minime, ce qui toutefois en règle générale réduit la conductivité. La fonction de conduction de courant peut être séparée de la fonction de mise en contact si l'on monte le contact (2) côté levier sur un dispositif séparé (3) de connexion électrique. Le levier de contact (1) n'exerce ainsi plus aucune fonction de conduction de courant et peut être optimisé uniquement du point de vue mécanique.
