Definitions

  • the invention relates to a load selector for step transformers according to the preamble of the first claim.
  • Load selectors on transformers serve to tap the control windings of these
  • the above DE 38 33 126 C2 proposes a load selector in which in each phase to be switched there are two movable mechanical switching contacts which can be pivoted simultaneously with one another on a common contact carrier, and in each case one vacuum switching cell, likewise arranged on the contact carrier, is provided in series with each of the two moving mechanical switching contacts .
  • Step contacts of the load selector are on a concentric circle in the wall of one
  • Insulated plastic cylinder arranged.
  • the vacuum switching cells are arranged horizontally on the contact carrier and are controlled or actuated by a cam track arranged on a further concentric circle, which is arranged axially between the circle of the fixed step contacts and an additional slip ring.
  • This known load selector has several disadvantages.
  • the horizontal arrangement of the vacuum switching cells on the common contact carrier results in an undesirably large diameter of the
  • Vacuum switch cells have certain ones depending on their switching capacity
  • Vacuum switch cell and the actuating means must have dictated radial expansion, which determines the overall diameter of the load selector.
  • Vacuum cell bellows occurs, whereby there is a risk that it tears.
  • Such remaining air in the area of the vacuum cell bellows can be arranged horizontally; Exclude reliably only by filling the load selector under vacuum; such vacuum filling is on site, e.g. after performed
  • load selectors generally have a large axial overall
  • Switching shafts of this type are usually made from GRP or other insulating material, although metallic switching shafts have also been proposed.
  • the contact carriers are in the known load selector by means of fastening screws on the
  • the object of the invention is to eliminate these disadvantages and to provide a generic load selector which allows a space-saving arrangement of the vacuum switching cells and their safe and reliable actuation under all operating conditions.
  • the contact carriers have sliding contacts. they are through
  • Knife sliding contacts which are mounted in the contact carrier, conduct the current over the
  • the contact carriers are each movable on the
  • Shift shaft arranged.
  • the switching sequence is guaranteed even in the event of height shifts due to tolerances and different thermal expansion of the oil tank and switch column.

  • the load selector consists of an insulating cylinder 1.
  • a switching shaft 2, preferably made of insulating material, is arranged centrally and extending longitudinally through the insulating cylinder 1.
  • the control shaft 2 is rotatable in a known manner; this is usually the case with Maltese drives, which are not shown.
  • the bearing of the selector shaft 2 on the bottom of the insulating material cylinder 1 is also not shown.
  • the control shaft 2 carries in each level of the fixed step contacts 16 to be actuated, which will be explained in more detail below, a contact carrier 3 which is rotatably mounted in a bearing block 4 on the control shaft 2.
  • the bearing block 4 is fastened to the selector shaft 2 with screws 4.1, 4.2.
  • the contact carrier 3 consists of a bearing part 5, a support housing 6 and the contact housing 7.
  • the individual components of the contact carrier 3 are connected to one another by screws 8, 9.
  • the contact housing 7 in turn in the exemplary embodiment shown consists of an upper contact housing part 10 and a lower contact housing part 11; both parts are in turn connected by further screws 12.
  • the contact housing 7 can equally well be formed in one piece.
  • the bearing part 5 has a bearing point 13, in which a bolt 14 is guided, which establishes the connection to the bearing block 4 and thus allows the rotary movement.
  • the bolt 14 is secured in position by a cross pin 15.
  • the entire contact carrier 3 can thus be pivoted as a complete assembly around the bolt 14 and thus relative to the fixed selector shaft 2.
  • fixed step contacts 16 are arranged, which are electrically connected to the taps of the control winding of the step transformer that is to be connected.
  • the fixed step contacts 16 can be connected by corresponding contacts 17, 18.
  • These contacts 17, 18 are arranged on the contact carrier in the horizontal direction next to one another such that when the switching shaft 2 and thus the contact carrier 3 are pivoted, one of the contacts 17, 18 reaches the adjacent new fixed step contact 16 before the other of these contacts reaches the previous fixed contact Step contact leaves.
  • One contact 17 acts as a switching contact
  • the other contact 18 acts as an auxiliary contact.
  • FIG. 2 the arrangement of the two contacts 17, 18 from above next to each other on the contact carrier 3 and the interaction with the respective fixed step contact 16 is shown.
  • the contact 17 acting as a switching contact is designed twice for reasons of the highest possible current carrying capacity, ie consisting of two parts 17.a and 17.b which are electrically connected to one another.
  • Each of the contacts 17, 18 consists of an upper contact part 17.1, 18.1 and a lower contact part 17.2, 18.2.
  • the contact 17 there consists of a total of four parts, namely two upper contact parts 17.1a and 17.1b and two lower contact parts 17.2a and 17.2b.
  • Both the upper contact parts 17.1, 18.1 and the lower contact parts 17.2, 18.2 of each of the two contacts 17, 18 are each rotatably mounted on the contact housing 7 about separate pivot points 19, 20, 21, 22. They are pressed towards one another by springs 23, 24, 25, 26, in the direction of the fixed step contact 16 located between them in the connected state.
  • two vacuum switch cells 27, 28 are fastened on each contact carrier 3, each by means of upper and lower fastening clamps 29, 30, 31, 32, such that the bellows 33, 34 and the actuating plungers 35, 36 of the vacuum switch cells 27, 28 extend upwards.
  • Two levers 37, 38 which each have a roller pin 41, 42 with a control roller 39, 40, are used to actuate the actuating plungers 35, 36 of the vacuum switching cells 27, 28. At their respective other free ends they act on the actuating plungers 35, 36 already described.
  • Both levers 37, 38 are rotatably mounted about pivot points 43, 44; it is also possible to provide a common pivot point.
  • the control rollers 39, 40 of both levers 37, 38 in turn correspond to a control ring 45, which has an upper control contour 46 and a lower control contour 47.
  • the control ring 45 extends radially on the inner wall of the insulating material cylinder 1. From FIG. 1 it can be seen that the first control roller 39 corresponds to the lower control contour 47, i.e. runs on it and in exactly the same way the second control roller 40 runs on the upper control cam 46.
  • the two control cams 46, 47 are thus used to actuate the vacuum switch contacts 27, 28 by pivoting the associated lever 37, 38 about its pivot point 43, 44 and thus the corresponding actuating plunger 35, 36 when the corresponding control roller 39, 40 runs onto a cam the vacuum switch cell 27, 28 actuated.
  • diverter contact ring 48 which has a connecting element 49 leading to the outside and is used for load dissipation.
  • the discharge contact ring 48 in turn corresponds to a mechanical one Diverter contact 50, which is arranged on the contact carrier 3 and, in a manner similar to the contacts 17, 18 already described above, in turn consists of an upper diverter contact part 50.1 and a lower contact part 50.2.
  • Both of these diverting contact parts 50.1, 50.2 are rotatably supported analogously separately about further pivot points 53, 54 and are pressed against one another by further springs 51, 52 such that they grip around the diverting contact ring 48 with a defined contact pressure.
  • the contact carrier 3 also has two rollers 55, 56 which roll on both sides on the diverter contact ring 48 and thus guide the entire contact carrier 3.
  • the arrangement described makes it possible to compensate for tolerances of any kind and, in particular, also to compensate for bending of the long control shaft.
  • the contact carrier 3, which can be pivoted about the control shaft 2 is in any case guided in a defined manner by the diverter contact ring 48, so that despite the tolerances described, the control rollers 39, 40 are actuated precisely and the vacuum switching cells 27, 28 are thus actuated - despite their only small actuation paths is.
  • FIG. 3 shows a further embodiment of a load selector according to the invention.
  • the contact carrier 103 is not rotatable, but rather is arranged to be longitudinally displaceable.
  • a switching shaft 102 which carries a longitudinally displaceable contact carrier 103.
  • the longitudinal displaceability is realized by means of a guide 104.
  • two vacuum switching cells of which only the front vacuum switching cell 105 is shown, are arranged upright.
  • contacts 106 in a circle in the wall of the insulating material cylinder 101 these in turn are connected by a switching contact and an auxiliary contact, of which only an upper contact part 107.1 and an associated lower contact part 107.2 are shown in the figure.

  • FIG. 5 shows a circuit in which, as shown in FIG. 2, the switching contact 17 consists of two contact parts 17a, 17b arranged next to one another.
  • the electrical connections are also only indicated in FIG. 2 corresponding to this illustration. It can be seen that the principle of operation does not differ, i.e. the same switching sequence can be achieved both by the circuit according to FIG. 4 and by the circuit according to FIG.
  • FIG. 6 Such a switching sequence that can be achieved by way of example is shown in FIG. 6.
  • a load selector with different switching steps is shown.
  • Such a load selector with different switching steps is known in principle from EP 0 160 125.
  • the center distance between the fixed step contact lying on the main winding and the two fixed step contacts adjacent to it is greater than the center distance between the other fixed step contacts. This enables the load selector to be used on transformers with higher nominal voltages; this means that a higher withstand voltage can be achieved.
  • suitable fixed step contacts which are designed differently, are also already disclosed for such a load selector.
