Definitions

  • the invention relates to an electrical high-voltage circuit breaker, in particular pressurized gas circuit breaker, the interrupter units of which are terminated on the outer end faces with connection plates, each having a connection surface for lines which are fastened there, each connection surface as a separate component with respect to the respective Connection plate is formed, and both on each component and on each connection plate holes for receiving fasteners are provided, which connect each component to the respective connection plate without the holes in each connection plate impair the closure of the interior of the interrupter unit.
  • Such an electrical high-voltage circuit breaker is known from US-A 2 660 631.
  • the high-voltage switch described there has connection plates and separate connection surfaces for fastening lines on its interrupter units. Holes for receiving fasteners are provided in connection plates and connection surfaces.
  • the contact surfaces are electrically contacted via the balls of a ball bearing, which is used for the rotatable mounting of a contact knife.
  • connection surfaces are formed from approaches on the connection plates.
  • the present invention has for its object to simplify the structure of the high-voltage circuit breaker by a different construction of the connection plates.
  • connection surface for the incoming or outgoing lines which can only be varied with regard to later types of installation of the circuit breaker in the switchgear, is therefore separate from the connection plate, which is also part of the interrupter unit and closes the interior thereof.
  • the connection plate is thus a component that is clearly assigned to the interrupter unit, so that its manufacture, and consequently also that of the circuit breaker and its gas filling, can be completely completed without having to decide which variant of the connection surface has to be attached to the connection plate.
  • This interchangeability of the connection surfaces is possible because the bores in the connection plate for receiving the component with the connection surface do not impair the closure of the interior of the interrupter unit and are easily accessible from the outside.
  • the division or arrangement of these holes is chosen so that each connection surface by 90 ° with respect to the respective connection plate is feasible. This means that practically all cultivation variations can be recorded.
  • FIG. 1 shows a partially sectioned view of an interrupter unit of an electrical high-voltage circuit breaker.
  • FIGS. 2 and 3 show views of a component with a connection surface from different directions.
  • the interrupter unit 1 In an electrical compressed gas high-voltage circuit breaker filled with SF6, the interrupter unit 1 is arranged on a support column 2.
  • the outer end face 3 of the interrupter unit 1 is closed gas-tight with a connecting plate 4.
  • it is connected to the mounting flange 5 of the interrupter unit 1 in a suitable manner with bolts 6.
  • connection plate 4 further includes threaded holes 7 arranged on a circumference with a uniform pitch, which are designed as blind holes. These threaded holes 7 are used to fasten the component 8, which is formed separately from the connecting plate 4, to the connecting surface 9.
  • This component 8 has a flange 10 which is perpendicular to the connecting surface 9 and in which the holes 11 are located for fastening to the connecting plate 4. These holes 11 have the same pitch and lie on the same circumference as the threaded holes 7 in the connection plate 4. The division of the holes 7 and 11 is selected so that the connection surface 9 on the connection plate 4 can be implemented by 90 °.
  • the component 8 is then fastened in the desired position with screws 12 to the connection plate 4.
  • the component 8 with the connection surface 9 can at any time on the gas-tight interrupter unit 1 of the electrical High-voltage circuit breakers are connected or removed again without this affecting the operational state of the gas-filled circuit breaker, because the interrupter unit 1 does not have to be opened for this.
  • This enables easy adaptation of the connection surface 9 to changed installation conditions both with regard to its position, since it can be implemented by 90 °, and also with regard to the arrangement and dimensioning of the fastening bores 13 provided in the connection surface 9 for receiving the fastening means with which the connection to the incoming or outgoing overhead lines, not shown, is made.
  • the replacement of the components 8 can be made in the simplest way.
