Definitions

  • the invention relates to a cylindrical step selector for step transformers according to the preamble of the claim.
  • Such step selectors are known: AT-PS 199 759.
  • This known construction requires different parts, e.g. for the contact rings and contact bridges and for the support arms of the contact bridges.
  • the step selector has a supporting insulating 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 is arranged loosely around the selector shaft 3 and which is held by means of the connecting line 5.
  • This completely made of insulating material support arm 7 lies with a flange 8, which is adapted to the tubular shape of the selector shaft 3, on the selector shaft, namely over a circumference of almost 120 °.
  • a cam 9 is also provided, which engages in a corresponding recess in the control shaft 3.
  • the support arm is fastened to the selector shaft 3 by means of a resin-impregnated self-hardening insulating tape 10, in that this insulating material tape is wound around the flange shoulder 11 of the supporting arm 7 and around the selector shaft 3.
  • FIG. 1 shows two such layers of the insulating tape 10, each of which is wound around an upper and lower flange shoulder 11. This is useful for larger and heavier versions of the tap selector.
