Definitions

  • the invention relates to a diverter for powerless switching between different winding taps of a tapped transformer for voltage adjustment.
  • Such a diverter is from the company publication of the applicant "diverter DEETAP ® U, Operating Instructions BA 249 / 02DE” Print Imprint 0204/200 already known.
  • This known diverter operates on the principle of Drehumstellers. It has an insulating scaffold on which in each case circularly fixed contacts are arranged in a plurality of horizontal planes.
  • a rotatable Isolierschaltwelle Inside this lsolierstoffgerüstes is a rotatable Isolierschaltwelle which carries at least one switching contact in each horizontal plane through which the corresponding fixed contacts depending on the respective basic circuit, for. B. as a star point taps changer, single-center diverter, double-center diverter, series-parallel diverter, star-delta diverter, are connected in different ways.
  • Adjusting the diverter from one operating position to another, d. H. the switching between different winding taps of the connected tapped transformer is, when the transformer is switched off, d. H. in the current and de-energized state, effected by turning the Isolierschaltwelle.
  • the rotation of the Isolierschaltwelle usually takes place on a step gear to which an electric motor drive or a mechanical manual drive acts, as will be explained in more detail below.
  • the upper end of the known Umstellers forms the Umstellerkopf with the attached upper gear and the underlying Maltese gear to drive the Isolierschaltwelle.
  • a shaft coming from the respective motor drive or manual drive is connected; the rotational movement is transmitted in the upper gear stage via a worm gear on a vertically mounted in the Umstellerkopf drive shaft, which in turn has at its lower end a Maltese crank.
  • the Maltese crank engages in a Maltese wheel, which is arranged at the upper end fixed to the Isolierschaltwelle.
  • the object of the invention is therefore to provide a generic diverter, which avoids these disadvantages and in which all described operating possibilities of Isolierschaltwelle with a single Umstellerkopf be realized.
  • the diverter according to the invention has only a single Umstellerkopf with a head flange on which either an upper gear stage for operation by motor or hand drive or a Handradantriebsflansch for operation by a handwheel or by means of a hexagonal adapter can be attached.
  • the drive shaft which, as described, carries at its lower end the Maltese crank, is identical in all forms of actuation.
  • a Umstellerkopf 1 which has a head flange 2 with a plurality of concentrically arranged fastening threaded bores 3.
  • an upper gear 4 is mounted on the head flange 2.
  • This upper gear stage 4 has, in a manner known per se, a worm wheel 5, which is connected to the shaft, not shown, coming from the motor or manual drive.
  • the worm wheel 5 acts on a gear 6 which is fixed on the vertically extending drive shaft 7.
  • the rotation is ensured by a spring / groove connection 8.
  • the drive shaft 7 is mounted in the head flange 2.
  • a Maltese crank 9 is attached; to prevent rotation serves another Spring / groove connection 10.
  • the Maltese crank 9 acts on a Geneva wheel 11, which is fastened with its flange 12 at the upper part of the Isolierschaltwelle not shown here.
  • the upper gear 4 is closed by a cover 13.
  • the drive of the diverter is thus effected by a spatially separated motor drive or a manual drive, wherein the rotational movement is transmitted by a corresponding wave train on the worm wheel 5 of the upper gear 4.
  • FIG. 2 the components of an alternatively usable handwheel drive are shown.
  • a Handradantriebsflansch 14 is provided, which is also on the head flange 2 - not shown fastened here and in which the drive shaft 7 is mounted.
  • the Handradantriebsflansch 14 has an upper cover 15 through which the drive shaft 7 is passed.
  • a handwheel 16 is fixed to the drive shaft 7.
  • the attachment is made by a thread 17 on the front side of the drive shaft 7; by means of a screw 18, the handwheel 16 is attached;
  • a spring / groove connection 19 is provided to prevent rotation, in their spatial position of the spring / groove connection 8 in the FIG. 1 equivalent.
  • a security lock 20 may be provided.
  • FIG. 3 an alternative hex drive is shown. He in turn has the Handradantriebsflansch 14, in which the drive shaft 7 is mounted. Instead of a handwheel here, however, above the cover 15, a hexagonal adapter 21 is in turn fastened by means of a screw 22 in the thread 17 of the drive shaft 7.
  • FIG. 4 is again the entire Umstellerkopf a diverter according to the invention, shown here with mounted handwheel drive. It can be seen that the head flange 2 as well as the entire Umstellerkopf 1 completely identical to the in FIG. 1 explained embodiment with upper gear stage. Instead of the upper gear stage here the Handwheelantriebsflansch 14 is mounted on the head flange 2.
  • the handwheel 16 acts on the drive shaft 7 and arranged at the lower end Maltese crank 9; this in turn on the Geneva wheel 11 and thus the Isolierschaltwelle.
  • an additionally arranged, known switching monitoring device 23 is indicated, which, however, is not relevant to the invention and is therefore not explained in any more detail.
