Definitions

  • the invention relates to a diverter switch of a tap changer according to the preamble of first claim.
  • Such diverter switches are known from DE-OS 42 31 353.
  • Two vacuum interrupters hereinafter referred to as VAC, are provided for each phase; These VAC and mechanical switch contacts are actuated by a switch shaft that can be rotated in both directions and is quickly rotated after a force accumulator is triggered.
  • a cam is fixedly arranged on the control shaft, which has a control cam on its face for each VAC, in which a role is positively guided, which acts on the actuating lever of the assigned VAC.
  • the mechanical contacts are switched by a switching segment, which is also rotated by the drive shaft and which switches between fixed contacts arranged on the circumference of the diverter switch.
  • the cams for actuating the two VACs and the switching segment for actuating the mechanical contacts are moved from one end position to the other and back again, regardless of the respective direction of movement of the tap changer; this means that the contacts which closed last when moving, ie rotating the selector shaft in one direction, opened first when moving back, ie rotating the selector shaft in the other direction, and vice versa.
  • Such a known diverter switch is therefore not suitable for realizing an asymmetrical circuit in which the same contact is always the first to be switched electrically or moved mechanically, regardless of the switching direction.
  • Such an unbalanced circuit is described, for example, in the unpublished DE-OS 44 07 945 and in a modified form with double-pole switching especially for diverter switches in the - also unpublished DE-OS 44 41 082.
  • FIG. 4 shows the last-mentioned asymmetrical circuit with double-pole switching, in which, regardless of the switching direction, the same actuation sequence, i.e. sequence switching means to be moved or actuated is present.
  • WO 89/08924 already has a special one for thyristor switches Spring jump drive described, which is independent of its drive direction always in one Should trigger direction, i.e. has only one output direction.
  • the object of the invention is therefore a diverter switch of the type described above specify, which can be driven in a simple manner with one in both directions of rotation Switching shaft allows the implementation of an asymmetrical circuit, such that The same VAC and mechanical actuation sequence regardless of the direction of rotation Switching elements should be accessible.
  • the main advantage of the invention lies in the fact that in that a conventional Energy storage device, which has an elevator carriage and an output part, as it does described for example in DE-PS 28 06 282, can be used. Doing so from the elevator carriage during the continuous elevator process according to the invention in addition, a direction perpendicular to the elevator direction, in the axial direction of the control shaft acting further movement of a coupling member to be explained in more detail.
  • both VAC and mechanical contacts different for each direction of movement of the drive shaft Partial cams with each other on an axially displaceable on the selector shaft arranged switch insert attached; by the axial movement of the Coupling member can be provided for the respective direction of movement of the drive shaft Partial cams also axially displaced and thus with the corresponding Switching elements for actuating the VAC as well as the mechanical contacts are brought into or out of engagement depending on the direction of rotation.
  • the diverter switch consists of a diverter switch housing, here an insulating cylinder 1, in which a central switching shaft 4 is arranged.
  • the selector shaft 4 is actuated in a manner known per se by an energy store 2.
  • the energy accumulator 2 has an elevator carriage 2.2, which is continuously pulled up by a rotating drive cam 2.1 of a drive shaft, not shown here, and which, when it reaches its end position, abruptly runs after an output part 2.3, which in turn drives the control shaft 4 in a known and not shown manner .
  • a contour 2.4 here on both sides, is provided on the side of the elevator carriage 2.2, in each of which a roller 3.3 of a coupling element 3 engages.
  • the coupling member 3 also consists of two levers 3.1, which are mounted laterally at approximately the level of the energy accumulator 2, and two articulated coupling rods 3.2, which extend vertically in the diverter switch housing parallel to the selector shaft 4 and down on their free The ends are connected to a switching insert 5 which is axially displaceable on the switching shaft 4. It is of course also possible to provide a contour 2.4 on the side of the elevator carriage 2.2 only on one side and accordingly to also arrange only one coupling element, but the paired arrangement described offers stability advantages.
  • the contour 2.4 described is designed so that - depending on the direction of movement of the elevator carriage 2.2 of the energy accumulator 2 - by means of the coupling element 3 when the energy accumulator 2 is pulled up, ie before the actual load switchover, the switching insert 5 axially on the control shaft 4 by a certain amount a is moved up or down.
  • the shift insert 5 axially displaceable on the shift shaft 4 can be rotated together with the latter by the triggered energy store 2; this is possible, for example, by a multi-toothed design of the shift shaft 4, which thereby allows the shift insert 5 to be positively carried along without impairing its axial displaceability.
  • a bearing for example a ball bearing, is provided between the lower part of the coupling element 3 and the switching insert 5, for example a bearing (not shown in more detail in the figures).
  • a bearing (not shown in more detail in the figures).
  • two cam disks 6, 7 Arranged one above the other on the switching insert 5 are two cam disks 6, 7 with end-side switching curves for actuating the two VAC 11, 12, each of which consists of an upper partial cam disk 6.1, 7.1 and a lower partial cam disk 6.2, 7.2 arranged directly one above the other.
  • two cams 8, 9 for actuating two movable mechanical contacts 13, 14 are also arranged, which will be explained later.
  • Actuating rollers 11.1, 12.1 are arranged laterally next to the respective cam disks 6, 7, such that, depending on the position of the switching insert 5, the two upper partial cam disks 6.1, 7.1 or the two lower partial cam disks 6.2, 7.2 correspond to the respective actuating rollers 11.1, 12.1.
  • These actuating rollers 11.1, 12.1 act on the respective VAC 11, 12 via angle levers 11.2, 12.2 and actuate them.
  • the two further cams 8, 9 for actuating the two movable mechanical contacts 13, 14 are provided on the switching insert 5.
  • the cams 8, 9 are also arranged one above the other Partial cams 8.1, 8.2; 9.1, 9.2 divided.
  • either the two upper partial cams 8.1, 9.1 or the two lower partial cams 8.2, 9.2 correspond to laterally arranged first rollers 13.1, 14.1 or second rollers 13.2, 14.2.
  • the engagement of the two lower cam plates 8.2, 9.2 is shown.
  • the roles 13.1, 14.1; 13.2, 14.2 are each connected to spring-loaded toggle levers 13.3, 14.3, which act on the rotatably mounted mechanical contacts 13, 14 in such a way that they can be brought into two switching positions beyond a dead center.
  • the first mechanical contact 13 acts as a switching contact SKM and, depending on the position it occupies, connects either the two fixed contacts SKM A or the two fixed contacts SKM B to one another.
  • the second movable contact 14 acts as a mechanical auxiliary contact HKM and, depending on the position it occupies, connects either the two fixed auxiliary contacts HKM A or the two fixed auxiliary contacts HKM B to one another.
  • the two movable mechanical contacts 13, 14 are arranged in the same horizontal plane.
  • Fig. 2 shows such an arrangement schematically from above.
  • the selector shaft 4 is arranged with the axially displaceable and rotatable together with it the switching insert 5 which carries the cams 6, 7, 8, 9 with the respective partial cams. It can also be seen that centrally around these cams for each phase the two VACs, one acting as an electrical switching contact SKV and the other as an electrical auxiliary contact HKV according to the circuit shown in FIG. 4, and the mechanical contacts for double-pole interruption, whereby one acts as a mechanical switch contact SKM and the other as a mechanical auxiliary contact HKM.
  • the areas in which the switching and actuating means of a phase are located are identified by areas delimited by arrows in FIG. 2.
  • the invention allows a simple implementation of asymmetrical circuits, ie a simple implementation of the same sequence of actuation of electrical and mechanical switching elements in a diverter switch regardless of its switching direction, which alternates due to the force accumulator that can be opened and released in two directions.
  • the movement required for the shift-direction-dependent shift according to the invention is generated in a simple manner during the continuous movement of the elevator carriage of a force accumulator known per se, ie before the actual switching process begins. All that is required is the additional contour described on the side of the elevator carriage; Except for this easily realizable change, the known energy stores can be used in unchanged form, which offers further advantages.
