Definitions

  • the invention relates to an arrangement comprising a circuit breaker breaker unit with a arranged between a first and a second arcing contact switching path and the switching path with an environment of the circuit breaker unit unit interconnecting switching gas channel, in the course of which a flow resistance of the switching gas channel enlarging barrier is arranged, wherein a first and a second Barrier within the switching gas channel are arranged successively spaced from one another, wherein between a first pipe section encompassed by a second pipe section and the second pipe section at least one of the barriers is arranged.
  • An arrangement is for example from the European patent specification EP 1 105 898 B1 known.
  • a circuit breaker breaker unit having a first and a second arcing contact piece. Between the two arcing contact pieces a switching path is arranged.

  • the arrangement of a cooling device is provided in the known construction, which has passage openings for switching gases.
  • the cooling device is intended to influence the temperature of a switching gas flowing through it.
  • This cooling device acts as a barrier, which increases the flow resistance in the switching gas channel.
  • the known cooling device is tubular and has passage openings for the switching gas in radial directions. Such a construction makes it possible to pass large quantities of switching gas through the cooling devices within short time intervals.
  • the Cooling device In order to ensure a sufficient cooling capacity, even for large volumes of switching gas, is the Cooling device correspondingly large volume, in particular in the axial direction to execute.
  • the object is achieved in an arrangement of the type mentioned above in that the at least one barrier with at least one, in particular two pipe sections is connected rigid angle, so that the pipe sections are fixed relative to each other.
  • the use of multiple barriers makes it possible to form different sections within the switching gas channel, in which there is a sequential backlog of switching gas in the course the switching gas channel is enabled. For example, it may be provided that different influences on the flow resistance of the switching gas channel take place at the first and the second barrier, so that deviating stagnations of the switching gas occur at the first and the second barrier. Thus, a change of flow resistance increases and flow resistance reductions can be effected in the course of the switching gas channel. Through these successive accumulation sections, which are to be traversed by the switching gas, the switching gas can be braked in an improved manner or specifically accelerated again.
  • the switching gas flow can be formed as laminar as possible, so that on the one hand a low-vortex introduction of the switching gas is in the switching gas channel, on the other hand, however, targeted at the barriers damming and swirling of the switching gas is caused to subsequently carry a laminar flow again.
  • the barrier can serve for a backflow of switching gas in the course of the switching gas channel
  • the barrier can be a mechanically bearing part of the circuit breaker unit to make the switching gas channel compact.

  • the pipe sections are arranged concentrically to each other, wherein an inflow of switching gas is centrally in an inner pipe section in the axial direction and after deflecting in radial directions and then limited by a encompassing pipe section, the switching gas in turn in an axial direction flows.
  • a so-called meandering of the switching gas channel is forced by a nesting of different pipe sections.
  • the meandering can take place in such a way that, in addition, in the course of the switching gas channel, the cross section of the switching gas channel is continuously or abruptly increased with increasing distance from the switching path.

  • the switching gas channel between the two pipe sections has an annular cross section, wherein the switching gas channel is flowed through within the first pipe section and within the annular cross section on the way from the switching path to a Heidelberggasausströmö réelle with opposite sense of direction from the switching gas.
  • the switching gas channel has a rotationally symmetrical as possible cross section.

Successive pipe sections with different annular cross-sections can embrace each other, with a one-time, in particular a repeated, deflecting the switching gas should be done by 180 °.
  • a further advantageous embodiment may provide that at least one of the barriers has a perforated plate.
  • a perforated plate is a body which has a plurality of passage openings which give the perforated plate a grid-like structure. This makes it possible to allow a switching gas to pass through the passage openings and at the same time to effect a mechanical stabilization between the pipe sections via the webs of the perforated plate remaining between the passage openings.
  • the barrier may also fill a supporting role within the circuit breaker interrupter unit to provide a mechanically stable rigid angle Ensuring interconnection of the pipe sections with each other.
  • gratings or similar devices can be used instead of a perforated plate.
  • At least one annular disc of perforated plate is used as a barrier in a section of the switching gas channel with an annular cross-section.
  • An annular disc of a perforated plate can be manufactured in a simple manner and accurately inserted into a portion of the switching gas channel with annular cross section between the first and second tube section.
  • circularly closed circumferential contact surfaces are given both for the first and for the second pipe section, via which a rigid connection between the pipe sections with each other is possible.
