Definitions

  • the invention relates to a cylindrical step selector for step transformers according to the preamble of claim 1.
  • the rigid connecting lines are additionally supported in several levels by comb-like scaffolding parts (AT-PS 199 759).
  • the advantage achieved with the invention lies in the multiple mounting of the essentially horizontal part of the connecting lines.
  • the first mounting takes place through the wall of the insulating material cylinder, in that the connecting lines are each seated in bores of the insulating material cylinder.
  • the second mounting is then carried out by the clamping strips made of insulating material, which are clamped together along the wall of the insulating material cylinder. This results in a very rigid position for the connecting lines, especially in the horizontal part of the connecting lines, which contributes to a secure fixation of the contact rings.
  • the step selector has a load-bearing insulating material cylinder 1, which carries the fixed step contacts 2 in different planes. It also has a tubular selector shaft 3 which can be rotated step by step in the usual way.
  • a contact ring 4 is provided for each contact plane, which are arranged loosely around the selector shaft 3.
  • Each contact bridge 6, which constantly grinds on the contact ring 4, serves to connect the contact ring 4 to the individual fixed step contacts 2.
  • Each contact bridge 6 is held and guided by a support arm 7 seated on the control shaft 3.
  • Each contact ring 4 is held by its associated connecting line 5.
  • the connecting lines 5 are each led horizontally out of the insulating material cylinder and arranged in alignment one above the other. They are each in a bore 8 of the wall of the insulating cylinder 1.
  • Two clamping strips 9, 10 made of insulating material extend along the wall of the insulating cylinder 1 and surround the connecting lines 5 in their horizontal part.
  • These terminal strips 9, 10 are each rigidly connected at the top and bottom to the insulating cylinder 1, but this is not shown in detail. They are clamped together by special clamping elements 11 made of insulating material, so that they grip around the connecting lines 5 tightly.
  • the connecting lines 5 After they have left the insulating material cylinder 1 horizontally, the connecting lines 5 are bent at right angles and run practically parallel to the terminal strips 9, 10. They can thus additionally be connected to the terminal strips by means of bandages, but this is not shown in detail.

Claims (2)

  1. Sélecteur cylindrique de prises pour transformateurs à prises, sélecteur dans lequel des contacts fixes de prises (2) sont maintenus dans plusieurs plans par un structure cylindrique en matière isolante et dans lequel il est prévu pour chaque plan un pont de contact (6), dont l'extrémité interne frotte sur un anneau de contact (4) placé dans ce même plan et qui est disposé librement autour de l'arbre de commutation (3) commandant les ponts de contact, tandis qu'il est fixé au moyen d'un conducteur électrique de liaison (5) rigide, sortant en principe latéralement et horizontalement de la structure en matière isolante et qui est assemblé avec cet anneau de contact, sélecteur de prises caractérisé en ce que la structure en matière isolante est constitué par un cylindre (1) en matière isolante et en ce que les conducteurs de liaison (5), alignés les uns au dessus des autres et sortant latéralement du cylindre en matière isolante, sont en outre maintenus par deux réglettes de serrage (9, 10) en matière isolante qui sont disposées à l'extérieur le long de la paroi du cylindre (1) en matière isolante et qui entourent les conducteurs de liaison (5) dans leur partie horizontale, tandis que ces réglettes de serrage sont rigidement reliées à l'extrémité supérieure du cylindre en matière isolante tout comme à son extrémité inférieure.
  2. Sélecteur cylindrique de prises selon la revendication 1, caractérisé en ce que les conducteurs de liaison (5), coudés à environ 90°, s'étendent le long des réglettes de serrage (9, 10) et sont reliés à celles-ci par des bandages.
