Definitions

  • the invention relates to a method for fastening a contact piece with its shaft in a bore in a cylinder wall according to the preamble of claim 1.
  • a fastening is known from DE-A-26 48 481.
  • insulating material cylinders manufactured using the filament process are used both for the diverter switch and for the tap selector. It is therefore necessary to arrange a large number of contact pieces in the wall of such an insulating material cylinder. It must be taken into account here that the shaft sitting in the wall of the insulating material cylinder acts as an electrode, on which high exit field strengths occur, mainly in the case of electrical shock loads. The contact pieces sitting in the wall are therefore provided with additional cross insulation. This is to prevent the occurring high exit field strengths from coming to rest on the glass fibers cut through with the bore and on the capillaries possibly forming around individual filaments.
  • the object of the invention is to provide a method for fastening the contact pieces in the wall of the insulating cylinder, which can be carried out in a simple manner while avoiding metallic fasteners which would lead to a deterioration in the field profile and which therefore require additional control electrodes. This object is achieved in the method mentioned at the outset by the method steps specified in the characterizing part of claim 1.
  • a further advantage is the fact that the contact pieces can be fastened in the cylinder wall or assembled from the outside alone. This is particularly important because the interior of such an insulating material cylinder is often inaccessible or because accessibility is hindered by other components of the tap changer.
  • the actual fastening of the contact pieces can either take place by means of squeezing or upsetting processes to be carried out from the outside as well, or plastic bolts or plastic pins can be used according to claim 3, which clamp the contact piece to the wall of the insulating material cylinder.
  • the contact piece 1 was inserted together with the insulating sleeve 2 into the hole in the wall 4 of the insulating cylinder, from the outside inwards, that is to say from the right to the left.
  • the insulating sleeve 2 had previously been pushed onto the shaft of the contact piece 1, to the extent that it abutted the bead-like thickening 3.
  • the bead-like thickening designed as an electrode shape forms the actual one Contact surface of the contact piece, while the shaft of the contact piece provided with the bores 7 forms the connection surface.
  • the edge 5 of the insulating sleeve 2 rests against the wall 4 of the insulating material cylinder and is locked by means of the device 8, which rests against both the insulating sleeve 2 and the wall 4.
  • screwing device 9 which engages with cross bolts 10 in the bores 7 of the connecting surface and which is supported on the device 8
  • the contact piece 1 is pulled to the right until it has reached the position shown below the center lines.
  • the bulge-like thickening 3 is pushed into the locked insulating sleeve 2 and expands it.
  • special plastic pins 6 are inserted into holes 11 provided for this purpose in the contact piece. After that, screw device 9 and device 8 can be removed.
  • the contact piece is fully assembled.
