Definitions

  • the invention relates to a gas-insulated switch, in particular a high-voltage circuit breaker, according to the preamble of claim 1.
  • the invention further relates to a method for producing the gas-insulated switch according to the invention.
  • Three-phase encapsulated gas-insulated high-voltage circuit breakers usually have a cylindrical housing, in which various components, such as three switch poles, three current transformers and a plurality of connecting conductors, are arranged. Furthermore, a plurality of openings are provided with flanges in the housing of the high voltage switch, which are gas-tightly closed by disc-shaped insulators. The connection conductors are led through holes in the insulators through the openings of the housing through to the outside.
  • a circuit breaker is known for example from EP 0563803 A1.
  • the housing of the circuit breaker is opened to assemble the individual components. Due to the limited space in the interior of the housing are relatively narrow, since the switch poles and the other components largely fill the interior of the circuit breaker housing, the space in the interior of the housing are limited, making the production of such a circuit breaker designed as relatively expensive.
  • the object of the invention is to provide a gas-insulated switch, in particular a circuit breaker, whose manufacture is simplified.
  • the switch according to the invention comprises an encapsulated housing constructed from a first and a second half-shell, also referred to as an encapsulating housing, wherein the half-shells are detachably connected to one another.
  • the first and the second half-shell are open in unconnected state on one side.
  • the assembly of lying in the interior of the housing components, such as switch poles, current transformers and connecting conductors is significantly simplified over said open side. Only after the assembly of all provided components, the connection of the two half shells together, whereby the housing of the circuit breaker is closed, preferably encapsulated, is.
  • the design of the housing of two interconnected half-shells and disassembly of the circuit breaker, for example, is simplified during inspection work.
  • the encapsulating housing can be opened for this purpose and work on the inner components of the circuit breaker, for example a replacement of the switch poles, can be carried out relatively easily.
  • the object of the invention is also to provide a method for producing such a switch.
  • a gas-insulated switch in particular a high-voltage circuit breaker at least three switch poles on a attached first half-shell and then a second half-shell is connected to the first half-shell.

Furthermore, the second half-shell 22 has an outlet flange 34 on an end face for the attachment of an outlet unit, not shown here. Of course, other arrangements of the busbar flanges 30 and the Abgangsflansches 34 are conceivable. It is also conceivable that the second half-shell 22 has only one busbar flange 30 or three or more than three busbar flanges.
  • Three current transformers 24 for measuring a current flowing from the bus bars 32 to the switch poles 14 are attached to the second half shell 22 inside the encapsulating case 12. In the illustration shown, only one of the current transformer 24 is visible, which covers the other two.
