Definitions

  • the invention relates to a diverter switch for a tap changer with electrical for each phase de-energized permanent main contacts.
  • a constructive version of a generic diverter switch with one for each phase Permanent power contact that switches electrically without power is known from WO 97/23888. That one
  • the diverter switch described has two fixed main contact pairs for each phase to be switched which can be connected by means of a movable permanent main contact. To operate them a cam is arranged on the selector shaft of the diverter switch, which for each switching phase has a separate control curve. There is a role in each of these control curves a, which acts on one of the movable permanent main contacts by means of mechanical coupling elements, so that this, depending on the contour of this control curve, can be pivoted about a central longitudinal axis is.
  • this known diverter switch has the disadvantage that the actuation of the movable Permanent main contact is structurally complex. There are a number of mechanical links, such as one Swing arm and various levers, required to move on the moving To transfer permanent main contact. In addition, the known arrangement requires a high level of power, to ensure that the permanent moving main contact with the corresponding corresponding fixed Bring permanent main contact pair in connection.
  • the object of the invention is to provide a diverter switch of the type mentioned above, which is simple is constructed, needs few transmission links and also only requires a small amount of power required for wiring.
  • FIG. 1 shows a diverter switch according to the invention in a schematic, perspective illustration, where for the sake of clarity a number of components and switching means that are not absolutely necessary to explain the invention.
  • the supporting element of the entire arrangement is a lower base plate 1, which is the movable Main contacts and the means to operate them and carries.
  • the single ones Switching elements and actuating parts of the diverter switch are omitted here.
  • On the base plate 1 are numerous recesses, openings and. a. recognize that for other components of the Diverter switch serve and are not explained here.
  • the permanent fixed main contacts 3, 4 are with these interacting, on the inner wall of an oil container, not shown, that the entire Diverter switch encloses, fastened.
  • each phase 2.1, 2.2, 2.3 There are three permanent main contact carriers for each phase 2.1, 2.2, 2.3 are provided, which are explained in more detail below. For the sake of clarity only one such complete permanent main contact with its actuating means for one Phase shown, which will be explained in detail below.
  • each of the permanent fixed main contacts 3.1 and 3.2 from one
  • Each of the contact blades 3.1.1, 3.2.1 is spring-articulated by means of contact springs 3.1.2 or 3.2.2.
  • a second fixed permanent main contact pair 4 This consists entirely of analog arranged below fixed Permanent main contacts 4.1, which are electrically connected to the other side B of the diverter switch stand, and fixed permanent main contacts 4.2 arranged above that for common Lead load transfer.
  • each of the permanent fixed main contacts 4.1 or 4.2 is from one A large number of individual contact lamellae 4.1.1 and 4.2.1, which in turn are completely analogous Contact springs 4.1.2 and 4.2.2 are individually spring articulated.
  • the permanent permanent main contacts 3.2, 4.2 are arranged on the first electrically conductive contact carrier 2.1 and form the common one Load transfer.
  • the fixed permanent main contacts 3.1 are on the second permanent main contact contact carrier 2.2 and the permanent permanent main contacts 4.1 are, electrically isolated, on the third Permanent main contact contact carrier 2.3 arranged.
  • a common movable permanent contact 5 this is electrically conductive, intended. It has a run-up surface 5.1 in the upper area on its left side, which corresponds to the fixed permanent main contacts 3.2 corresponds, and on the right side a contact surface 5.2, which corresponds to the permanent permanent main contacts 4.2. In its lower area it points to the on the left side there is a contact surface 5.3, which corresponds to the permanent permanent main contacts 3.1, as well as on the right side analogue another contact surface 5.4, which in turn with the fixed permanent main contacts 4.1 corresponds.
  • the movable permanent main contact 5 does not have one Bearing 6 shown in detail, such that it is in the longitudinal axis of the diverter switch around a central position is pivotable around. The bearing 6 is held in an upper base plate, not shown. The pivoting path of the permanent main contact 5 is indicated in the figure by two double arrows.
  • the contour of the two run-up surfaces 5.1, 5.2 is dimensioned such that they are spherical Swiveling the movable permanent main contact 5 around its bearing 6 constantly with the fixed Permanent main contacts 3.2 and 4.2, which, as explained above, both with the electrical load transfer of the diverter switch are connected. They therefore run constantly on these fixed ones Permanent main contacts 3.2 and 4.2 from; this takes the form of sliding.
  • the two contact surfaces 5.3 and 5.4 respectively arranged below are such dimensioned in their contours that they only when pivoting the moving permanent main contact 5 in one of its two end positions in contact with the corresponding fixed Step contacts 3.1 and 4.1, which, as also already explained, with one of the two Diverter switch sides A or B are connected, come into contact. In the middle position of the moving permanent main contact 5, however, have no contact surfaces 5.3 and 5.4 electrical contact.
  • the actuation of the movable main contact 5 is carried out by an actuation tab 7 has a guide 7.1 in the form of an elongated hole and is articulated by fastening means 7.2.
  • a deflection crank 8 which in turn by one Pivot 8.1 is stored.
  • this deflection crank 8 has a contour that consists of Roller interventions 8.3 and a blocking contour 8.4 in between.
  • one Drive disc (9) of the diverter switch can be seen, which does not have a central opening 9.1 for the shown, drive shaft of the diverter switch, which in turn from the triggered - not shown-energy storage is operated.
  • the invention has two, functional for actuating the movable permanent main contact 5 successively operating crank drives.
  • This arrangement is also space-saving, especially since the cams and protruding parts required by the state of the art Lever transfers are no longer required.
