Definitions

  • the invention relates to an oil operated tap selector for tap changers of tap transformers, as described in more detail in the preamble of the associated patent claim.
  • control electrodes of such tap changers with additional insulation to increase the dielectric strength.
  • the control electrodes are generally wrapped with paper, which then provides a substantial improvement in the dielectric strength after the oil impregnation.
  • the method of wrapping paper encounters difficulties with control electrodes, e.g. are intended only for shielding terminal lugs of individual contacts or for shielding individual screw connections and which should also be attachable to special brackets. Control electrodes of this type cannot be wrapped with paper because of their special shape and because of the required possibility of being plugged onto special holders.
  • the object of the invention is to achieve a further improvement of the 'described control electrodes of tap changers. This object is achieved according to the invention by the means specified in the characterizing part of patent claim 1.
  • the advantage achieved by the invention is, in particular, that even with very small control electrodes and control electrodes whose shape is not suitable for wrapping with paper, and also with control electrodes which can be plugged onto special holders, an increase in the dielectric strength is achieved, without these control electrodes having to be wrapped with paper.
  • the press chip molded part can be designed as a shell, which from the outset e.g. is arranged around the terminal lug and into which the actual control electrode is pushed.
  • insulating rods 3 are fastened to an upper cage ring 1 and a lower cage ring 2 and carry the individual step contacts 4.
  • the insulating rods 3 are fastened to the cage rings by means of screws 5.
  • the step contacts 4 seated on the insulating rods 3 are spherical to the inside of the step selector. On the outside, they are each provided with a connecting lug 6 for connecting the supply lines.
  • control electrode 7 The sharp-edged parts of the fastening screws 5 are shielded with a control electrode 7.
  • a molded part 8 made of pressboard is arranged in a form-fitting manner around this control electrode.
  • a control electrode 9 and 91 is arranged around each of the connection lugs. These control electrodes 9 and 91 are also each surrounded by a molded part 10, 11, also made of pressboard.
  • These molded parts 8, 10 and 11 bear in a form-fitting manner on the control electrodes 7, 9 and 91, respectively, in the area of the control electrode which is decisive for the control of the electric field.
  • control electrode 9 it may be expedient to design the control electrode 9 together with the molded part 11 surrounding it so that it can be plugged onto resilient projections 12 seated on the stepped contact 4 in a manner known per se.
  • the molded part 10 can also be designed as a shell from the start with the step contact 4 sitting together on the insulating rod 3, so that when the actual control electrode 91 is attached, it must be pressed into the shell.
  • control electrode 9 and molded part 10 can also be fixedly mounted from the start together with the step contact 4.
