Definitions

  • the invention relates to a mechanical switching contact for double-pole switching, especially in a diverter switch a tap changer.
  • a switching arrangement for a diverter switch of a tap changer which has a main mechanical switching contact and a likewise mechanical resistance switching contact.
  • both the main switching contact and the resistance switching contact each consist of two mutually coupled actuated single break contacts, each a single break contact of both the main switching contact and the resistance switching contact with the first Lastumschalterseite is electrically connected and the other single break contact both the main switching contact and the resistance switching contact with the second Lastumschalterseite electrically connected is.
  • the individual break contacts of the main switch contact by a first changeover switch and the individual break contacts of the resistance switching contact by a second changeover switch can be connected.
  • WO 96/30922 From the WO 96/30922 is a diverter switch for a tap changer known in which are provided as a technical realization possibility of such a double-pole switching about a pivot pivotable mechanical contacts. Furthermore, spring-loaded toggle lever are provided, which act on the rotatably mounted mechanical contacts in such a way that they can assume two switching positions beyond a dead center. The two movable contacts are arranged separately in the same horizontal plane in the outer area of the diverter switch for each phase.
  • the object of the invention is therefore to provide a mechanical switching contact for double-pole switching, which is simple and consists of little as easy to assemble components, it is modular and designed as an independent module that installed without further adjustment or adaptation work as in a diverter switch can be and there also still takes up as little space.
  • a significant advantage of the mechanical switching contact according to the invention consists in its extremely compact, simple design. With only a few parts, both mechanical main switching contact and mechanical resistance switching contact can be prefabricated as identical, modular assemblies. For main switching contact and resistance switching contact so same modular mechanical switching contacts are used; Main switching contact and resistance switching contact each phase can be realized in a simple manner as a common assembly of two identical, interconnected modular switch contacts according to the invention.
  • FIG. 1 illustrated mechanical switching contact according to the invention are explained in more detail. It has an insulating carrier 1, which receives the other components described below.
  • the Isolierstoffong 1 is provided with parallel longitudinal guides 1.1, ... 1.4 in the form of through holes, which will be discussed in more detail below. Furthermore, it has two bearings 1.5 and 1.6, in which a contact carrier 2 is rotatably supported by a bearing pin 3. In the areas of the two bearings 1.5 and 1.6 lateral Kalottenam 1.7 and 1.8 are provided, which will also be discussed in more detail. Further, the Isolierstoffzel has molded contact receptacles 1.9 ... 1.12, in which fixed contacts 4 ... 7 are arranged.
  • the contact carrier 2 is rotatably supported by means of a bearing 2.1 and the already mentioned bearing pin 3 in the insulating substrate 1. It has a pivoting arm 2.2, which is pivotable about the bearing 2.1 and in turn has a contact 2.3 at its free end.
  • This contact 2.3 consists of a through hole parallel to the longitudinal axis of the bearing 2.1 and the bearing pin 3. Laterally in the field of contact 2.3 each an abutment 2.4 and 2.5 is also formed dome-shaped. At its other, opposite free end, the contact carrier 2 has an actuating contour 2.6.
  • an electrically conductive contact piece 8 is arranged, which has contact rollers 8.1 and 8.2 at both free ends.
  • These contact rollers 8.1, 8.2 respectively correspond with either the fixed contacts 4 and 5 on one side of the insulating substrate 1 or the fixed contacts 6 and 7 on the other side of the insulating substrate 1, depending on the direction in which the contact carrier 2 to the camp 2.1 is pivoted.
  • telescopic guides 9 and 10 are arranged on both sides.
  • These telescopic guides 9, 10 consist of two telescoping pieces of pipe. They each have a free end, a dome 9.1 or 10.1, with which they are supported in one of the Kalottenfactn 1.7 and 1.8 of Isolierstoffongs.
  • the telescopic guides 9, 10 At their respective other free end, the telescopic guides 9, 10 have a spherical abutment, with which in turn they are supported in each case in one of the two abutment seats 2.4, 2.5 on both sides of the contact carrier 2.
  • a snap mechanism is realized in a simple manner, on the one hand prevents the Contact carrier 2 can assume an undefined intermediate position and on the other hand ensures sufficient contact pressure of the contact rollers 8.1 and 8.2 on the respective fixed contacts.
  • the lateral caps 9.1 and 9.2 of these telescopic guides 9 and 10, which are respectively mounted in the Kalotteniern 1.7 and 1.8 of 1 Isolierstoffehrs act as a spatial, three-dimensional storage.
  • the telescopic guides 9 and 10 change in the switching, ie the pivoting of the contact carrier 2, both their length - therefore formed telescopically - as their spatial position.
  • FIG. 3 two of these switching contacts according to the invention are shown, which are combined to form a complete mechanical switching unit for a phase of a diverter switch.
  • the one switching contact I acts as the main switching contact and the other switching contact II as a resistance switching contact.
  • the same parts are provided with the same reference numerals - it can be seen that both modules are constructed completely identical. For reasons of clarity, not all of the details explained have been provided with reference numerals in this representation.
  • FIG. 3 is, as well as in FIG. 1 shown for a single switching contact, an asymmetric version of the operating contour 2.6 of the contact arm 2 has been selected.
  • the two switching contacts I and II have been installed 180 degrees offset from each other, so that the two. Actuating contours are turned to each other.
  • connection of the two switching contacts I and II is carried out by common connecting pins 13 ... 16, which are guided by the respective longitudinal guides 1.1 ... 1.4 and bolted on both sides. Furthermore, in FIG. 3 to see that the respective opposite fixed contacts 4 and 6 of each switching contact I and II are electrically connected to each other by a respective connecting cable 17, 18. Furthermore, it can be seen that the adjacent contacts 5 and 7 of each switching contact on the one side by a first conductive connection 19 and corresponding to the adjacent fixed contacts 7 and 5 on the other side by a further conductive connection 20 are electrically connected to each other. This can be a double-pole switching with a diverter switch on a tap changer realize.
  • FIG. 4 shows again:
  • the selector of the tap changer is shown schematically, which performs a powerless preselection of the new winding tap n + 1 of the tap changer to be switched to, while still the previous winding tap n is electrically connected.
  • the two sides of the diverter switch A and B between which an uninterrupted changeover under load is to occur in the sequence.
  • the mechanical switching contacts are shown, in the left branch, the main switching branch, the main switching contacts SK.
  • the indices A and B denote the respective assignment of the corresponding individual contact to the side A or B of the diverter switch.
  • the resistance branch the resistance switching contacts HKM are shown quite analogously; the same applies to the indices.
  • the dotted line shows the part of the circuit that is technically realized by the two mechanical switching contacts I and II according to the invention.
  • the series-connected first vacuum switching cell SKV for load dissipation is still shown in the main switching branch, in the resistance branch are the series circuit a switching resistance and a second vacuum switching cell HKV for load dissipation L shown.
