Definitions

  • the invention relates to an electrical high-voltage circuit breaker, in particular a compressed gas circuit breaker, the interrupter units of which are terminated on the outer end faces in each case with connection plates which have a connection surface for lines which are fastened there.
  • connection surfaces are formed from approaches on the connection plates. This requires a large number of differently designed connection plates, since both the orientation of the connection surfaces can change depending on the switchgear in which the circuit breaker is to be installed, as well as the arrangement and dimensioning of the fastening means on the connection surfaces with which the switch guided electrical cables, especially outdoor cables, are attached. Since the connection plates form a part that closes the interior of the interrupter units, each individual switch must therefore be manufactured exactly according to its intended use.
  • 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 is formed as a separate component with respect to the connection plate, bores are provided in both components for receiving fastening means which connect the component with the fastening surface to the connection plate, the bores in the connection plate lying in an edge region which is above the outside diameter protrudes from the interrupter unit, and the division or arrangement of the corresponding bores in both components enables the connection surface to be fastened to the connection plate in an implementable manner.
  • connection surface for the incoming and outgoing lines which can only be varied with regard to later installation types of the circuit breaker in the switchgear assembly, 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 lie in an edge region which projects beyond the outer diameter of the interrupter unit, so that the closure of the interior of the interrupter unit is not impaired by them.
  • the holes and thus the fasteners are easily accessible from the outside.
  • the division or arrangement of these holes is chosen so that the connection surface can be implemented. This means that practically all attachment variants can be recorded.
  • the component with the connection surface can be implemented by 180 °.
  • the edge area with the holes is only on opposite sides the connecting plate, so that the area perpendicular to it, which determines the pitch between adjacent switch poles, is not enlarged compared to the outer diameter of the interrupter unit.
  • FIG. 1 shows a view of an interrupter unit of an electrical high-voltage circuit breaker.
  • FIG. 2 shows a top view of the connection plate and
  • FIG. 3 shows a side view of the component with the connection surface.
  • the interrupter unit 1 is arranged on a support column 2. It is closed gas-tight at its end faces 3, 4 with a connecting plate 5.
  • the connection plate 5 is connected in a suitable manner, not shown, to the mounting flange 6 via bores 7.
  • connection plate 5 further contains holes 8 arranged on a circular circumference with uniform division. These lie in each case in an edge region 9, which in each case forms an arcuate section and is provided on two opposite sides of the connection plate 5, in such a way that it is in each case by arrows indicated outer diameter 11 of the interrupter unit 1 protrudes.
  • the lateral edges 10 of the edge areas 9 are rounded off to this outer diameter 11, so that in the area of the contact plate 5 which is perpendicular to the edge areas 9, the outer diameter 11 determines its dimensions.
  • the separate component 12 with the connection surface 13 and the fastening bores 14 provided thereon for the lines (not shown) to be connected has a flange part 15 which likewise forms an arcuate section 16.
  • This flange part 15 on the component 12 corresponds to the edge area 9 on the connection plate 5.
  • holes 17 are arranged on the flange part 15, which lie with a corresponding uniform division from the same circumference as the holes 8.
  • the separate component 12 with the connection surface 13 is now connected to one of the two edge regions 9 of the connection plate 5 via bolts 18.
  • the component 12 can thus be implemented by 180 °.
  • the component 12 lies on the lower end face 4 of the interrupter unit 1 on the right side and on the upper end face 3 of the interrupter unit 1 on the left side.
  • connection surface 13 can be connected to the gas-tight interrupter unit 1 of the electrical high-voltage circuit breaker or removed again at any time 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 the connection surface 13 to be easily adapted to changed installation conditions, both with regard to its position, since it can be implemented by 180 °, and also with regard to the arrangement and dimensioning of the fastening bores 14 provided in the connection surface 13 for receiving the fastening means with which the connection to the incoming or outgoing overhead lines, not shown.
  • the replacement of the components 12 can be made in the simplest way.
