Definitions

  • Such a dome contact piece is known from DE-B-11 60 914. It has the advantage of simple manufacture and easy assembly of its components, in particular by means of Au. tomatoes can be done. The force exerted on each lamella by the leaf springs also results in an even contact pressure.
  • the selectable number of contact lamellae is limited by the fact that they should have a width of 6 to 10 mm on the blunt side, because if the width is too small, a lateral tilting of the lamellae can occur under certain circumstances, whereby the contact pressure is released would. Although this can be avoided by means of solid partition walls which guide the lamellae, the tubular housing loses its simple inner cylindrical shape, which makes its manufacture more difficult.
  • the invention has for its object the simple manufacture of the housing. to allow such dome contact piece despite the presence of an axially extending partition between the fins.
  • the dome contact piece of the type described above is designed according to the invention in such a way that the cylindrical housing surrounding the lamellae is formed from a strip of thin-walled sheet metal bent into a cylinder, the width of which approximately corresponds to the length of the lamellae, one of the axially extending ones Edges of the sheet metal strip are bent radially inward at a height selected less than the height of the lamellae and that this thin-walled cylindrical housing lies in a thicker-walled cylindrical outer housing of the dome contact piece.
  • the intermediate wall is therefore not rigidly connected to the cylindrical outer housing, but is arranged on a separate thin-walled cylindrical housing. Since this thin-walled cylindrical housing is formed from a strip of thin-walled sheet metal bent into a cylinder, the intermediate wall is obtained in the simplest manner by bending one of the axially extending edges radially inwards. The height of the bent part is chosen to be smaller than the slat height. This partition protrudes between two fins and results in good guiding and fixing of the fins in terms of both their circumferential and longitudinal directions. The contact pressures of the lamellae, generated by the leaf springs e f , are absorbed by the thick-walled outer housing.
  • the bent inner cylindrical housing is advantageously made of a non-magnetic sheet with high mechanical strength and hard surface, such as. B. bronze or brass. This prevents the leaf springs from being pressed into the sheet, which would reduce the contact pressure.
  • FIG. 1 shows a longitudinal section through a dome contact piece designed according to the invention.
  • FIG. 2 shows, partially in section, a view of an end face of the dome contact piece, viewed in the direction of the arrow drawn in FIG. 1.
  • Figure 3 shows the inner cylindrical housing on a smaller scale.
  • the dome contact piece 1 for the connection of two round conductors of a compressed gas-insulated metal encapsulated high-voltage switchgear has a thick-walled outer housing 2, which has a substantially cylindrical shape.
  • the front outer edges 3 as well as the edges 4 next to a constriction 5 for receiving a safety spring, not shown, are greatly rounded, so that the outer housing 2 also acts as a shield controlling the electrical field in the course of the conductor connection.
  • the inner diameter 6 in the area of the constriction 5 is smaller than the inner diameter 7 for receiving the lamellae 8, so that a shoulder 9 is formed between the two, against which the lamellae 8 rest on one side.
  • Each lamella 8 is trapezoidal.
  • the pointed side 10 of the lamella 8 forms the contact surface with the conductors, not shown, to be connected.
  • the blunt side facing the outer housing 2 contains a central one Groove 11, which is laterally at a distance 12 from the slat side surface 13.
  • a leaf spring 14 is arranged, which supports the lamella 8 with respect to the outer housing 2 and thus causes the contact pressure of the lamella 8.
  • the leaf spring 14 does not abut the inner bore 15 of the outer housing 2, but a thin-walled cylindrical housing 16 is inserted into this.
  • This thin-walled cylindrical housing 16 is formed from a strip of thin-walled bronze sheet bent into a cylinder. The width of the sheet corresponds approximately to the length of the lamellae 8. An edge 17 of the axially extending edges of the sheet is bent radially inwards at a height 19 selected less than the lamella height 18. As a result, this bent edge 17 forms an intermediate wall 20 which projects between two lamellae 8.
  • the assembly of the dome contact piece 1 is very simple. First, the thin-walled cylindrical housing 16 is inserted into the inner bore 15 of the outer housing 2 until it comes to rest on the paragraph 9. Then the individual slats 8 are inserted from the side and also reach paragraph 9 to the system. Now the leaf springs 14 are inserted into each groove 11 of the slats 8. Finally, in front of the end face of the thin-walled cylindrical housing 16, the leaf springs 14 and the lamellae 8, a disk 23 is placed for axial securing, which is fixed at some points in the outer housing 2 by caulking.
