Definitions

  • the present invention relates to a modular disconnector with independent moving contact closure, capable of interrupting and disconnecting one or more electric circuits, which can be mounted in control units or panels or containers suitable for the purpose.
  • Disconnectors are electrical actuation devices provided with mechanisms that allow the opening and closure of one or more moving contacts by means of an external lever or handle that can be accessed by the user.
  • a first problem is that of limiting the number of components that constitute the actuation mechanism, in order to contain both the costs of the individual parts and the costs of their assembly.
  • Another important problem is to reduce the wear of the contacts during opening and closure, in order to ensure the correct operation of the product for a longer period of time.
  • the closure speed is actually directly proportional to the speed of actuation of the actuation lever.
  • Document DE 8905764 U discloses a modular disconnector according to the preamble of claim 1.
  • the aim of the present invention is to provide a disconnector with independent moving contact closure that overcomes the drawbacks of the cited prior art.
  • An object of the invention is to provide a disconnector that is economical also from the point of view of production.
  • Another object of the invention is to provide a device that can be installed inside control units, control panels, and containers in general suitable for the purpose.
  • Another object is to provide a device that is reliable and durable.
  • the disconnector generally designated by the reference numeral 1, comprises a casing 11 that encloses various components including an actuation lever or handle 10, which can be operated from the outside and is associated with a linkage or cross-member 2, which is in turn connected to an intermediate member or pusher 3.
  • a traction spring 4 and a compression spring 5 are applied respectively to the pusher 3 and are adapted to determine the contact pressure and the closure speed.
  • a double moving contact 6 is rigidly coupled to a slider 7, which is connected to a double elastic hook 8.
  • the double moving contact is adapted to make contact with fixed contacts 12, each being associated with a respective terminal 13 provided with a locking screw 14.
  • An indicator 15 is kinematically associated with the slider 7 in order to indicate the position of the moving contact.
  • the motion is transmitted, by means of the linkage 2, to the pusher 3, to which the springs 4 and 5 are applied.
  • the first spring 4 determines the contact pressure and the closure speed, which is independent of the speed with which the handle is operated, while the second spring 5 causes the contacts to open.
  • the moving contact 6 is rigidly coupled to the slider 7, which is retained in position by the double elastic hook 8.
  • the pusher 3 has a wider portion 33, which is blended with inclined portions 16, so that by lowering the pusher the wider portion 33 divaricates the ends 18 of the double hook 8, moving them outside the step 17 of the slider 7.
  • the closure speed of the contact is independent of the speed with which the actuation lever is operated.
  • the motion is ensured by the spring 5, which during closure is kept compressed by passing beyond the dead center of the toggle constituted by the pusher 3, the linkage 2 and the actuation lever, while during the opening step, as soon as the conditions are restored, the spring 5 pushes the pusher 3, which in turn moves the slider 7, the moving contact 6, the linkage 2 and the actuation lever 10 into the open position, shown in Figures 1 and 2.
  • the mechanism Since the mechanism has an independent closure action, it in fact allows the user to operate the actuation lever in any manner, ensuring in any case the maximum contact closure speed.
  • the disconnector also reduces the formation of electric arcs, which as is known causes deterioration of the insulating parts.

Claims (5)

  1. Modularer Trennschalter mit sich unabhängig bewegender Kontaktschließung, aufweisend ein verschiedene Bestandteile umgebendes Gehäuse, umfassend einen Betätigungshebel oder eine Handhabe (10), die von der Außenseite betätigt werden kann, um eine kinematische Kette zu steuern, die zum Öffnen und Schließen wenigstens eines sich bewegenden Kontakts (6) und eines entsprechenden ortsfesten Kontakts (12) geeignet ist, wobei jeder ortsfeste Kontakt mit einem entsprechenden Anschlußelement (13) verbunden ist, wobei die kinematische Kette ein Hebelsystem aufweist, das zur Betätigung eines Drückers (3) geeignet ist, der durch wenigstens ein elastisches Element (4) zur Steuerung der Schließgeschwindigkeit der Kontakte und zur Steuerung des Kontaktdrucks in der geschlossenen Position betätigt wird,
    gekennzeichnet durch
    einen Gleiter, der durch Zwischenschaltung des Drückers (3) mit dem sich bewegenden Kontakt verbunden ist.
  2. Trennschalter nach Anspruch 1,
    dadurch gekennzeichnet,
    daß das Hebelsystem eine Anlenkung(2) aufweist, die mit der Handhabe (10) und dem Drücker (3) verbunden ist.
  3. Vorrichtung nach Anspruch 1 oder 2,
    dadurch gekennzeichnet,
    daß das wenigstens eine elastische Element zwei Federn aufweist: eine Zugfeder (4), die zur Festlegung des Kontaktdrucks und der gegenseitigen Kontaktschließgeschwinidkeit geeignet ist, und eine Druckfeder (5), die zur Festlegung der gegenseitigen Öffnung der Kontakte geeignet ist.
  4. Vorrichtung nach einem oder mehreren der vorhergehenden Ansprüche,
    dadurch gekennzeichnet,
    daß der sich bewegende Kontakt (6) durch einen doppelten Kontakt gebildet ist, der starr an den Gleiter (7) gekoppelt ist, welcher wiederum an einen doppelten elastischen Haken (8) gekoppelt ist, wobei der sich bewegende Doppelkontakt (6) dazu geeignet ist, einen Kontakt mit den festen Kontakten (12) herzustellen, von denen jeder mit einem entsprechenden Anschlußelement verbunden ist.
  5. Vorrichtung nach einem oder mehreren der vorhergehenden Ansprüche,
    gekennzeichnet durch
    einen Anzeiger (15), der kinematisch mit dem Gleiter (7) verbunden ist, um die Stellung des sich bewegenden Kontaktes anzuzeigen.
