Definitions

  • the invention relates to a compressed gas circuit breaker with a first, drivable arcing contact, a second, fixed arcing contact, a concentric to this nominal current path with a first, drivable nominal current contact and a fixed nominal current contact as well as with a compression device, which via a
  • Filling valve can be connected to a low-pressure space arranged radially outside the rated current path, at least the first drivable arcing contact being designed in a ring shape and being carried by a switching tube, via the output of which switching gases resulting from the switching-off process reach an outflow volume which is provided radially to the switching tube Blow-out openings in connection with the low pressure chamber.
  • Such a pressure gas circuit breaker goes with regard to its contact arrangement and configuration, the first drivable arcing contact being ring-shaped and being carried by a switching tube, via which switching gases resulting from the switching-off process enter an outflow volume which is a low-pressure space, essentially for example from DE -OS 25 32 088.
  • the contact arrangement is assigned a compression device which can be connected to the outflow volume via a filling valve, as is also apparent from DE-OS 26 18 087.
  • the invention is based on the problem of creating a compressed gas circuit breaker according to the preamble of claim 1, in which the non-ionized extinguishing gas present at the filling valve of the compression device, required for the subsequent switch-off process, is not contaminated by the ionized and contaminated switch gas resulting from a switch-off process in the event of a rapid reclosure becomes.
  • the additionally created suction area is spatially separated from the outflow volume by partitioning it off from the suction area by a partition which is firmly connected to the inner wall of the nominal flow path, in particular in the form of a fixed compression cylinder.
  • the partition is expediently designed as a hood which, with its cylindrical region, wall of the nominal current path can be connected by a welded, soldered or adhesive connection.
  • the non-ionized extinguishing gas present at the filling valve of the compression device which is required for the subsequent switch-off process, can be made available via the suction area of the compression device without it being caused by a switch-off process resulting ionized and contaminated extinguishing gas is contaminated. Rather, the ionized extinguishing gas reaches an outflow volume that is spatially separated from the intake area before it is fed to the low-pressure space.
  • the compressed gas circuit breaker essentially consists of a first, drivable arcing contact 2, a second, fixed arcing contact 3, a concentric to this nominal current path 4 with a first, drivable nominal current contact 5.
  • a fixed nominal current contact 6 and the first, drivable Arcing contact 2 partially surrounding boiler room 7 is provided. This is connected to a compression device 9 via a check valve 8.
  • the first, drivable arcing contact 2 is connected to an insulating nozzle body 10, which has a gas duct 12 which can connect the arcing space 11 to the heating space 7 after initiation of a switch-off process and which opens into the arcing space 11.
  • the arcing contact is designed as a tulip contact and is carried by a switching tube 13 which is connected to the switching rod 14.
  • the outlet 15 of the switching tube 13, formed by a radial opening is located in an outflow volume 16 after the disconnection of the arcing contacts 2, 3 during a switch-off process, so that the extinguishing gas resulting from a switch-off process is also included the at least partially cooled quenching gas flowing back from the heating chamber 7 via the gas channel 12 into the arc chamber 11 in the last phase of a switch-off process reaches the outflow volume 16 via the switching tube 13.
  • This extinguishing gas is supplied to the low-pressure chamber 18 arranged radially outside of the nominal current path 4 via blow-out openings 17 within the nominal current path 4.
  • the nominal current path 4 in the region of the blow-out openings 17 is one Surround baffle 20, which is arranged at a distance from the blow-out openings 17.
  • a suction area 23 adjoins the cylinder base 21 of the compression volume 22 of the compression device 9 and is also connected to the low-pressure chamber 18 via openings 24 provided radially in the nominal current path 4.
  • the suction area 23 is partitioned off from the outflow volume 16 by a partition wall 26 which is fixedly connected to the inner wall 25 of the nominal current path 4 and which is designed as a hood and is connected gas-tight with its cylindrical region 27 to the inner wall 25 of the nominal current path 4.
  • this compressed gas circuit breaker is now to be used for rapid reclosure after a switch-off process, the switch-on process is initiated immediately after the filling valve 28 provided in the cylinder base 21 is opened - the cylinder base 21 also has the pressure relief valve 29 - via the suction region 23 to the compression volume 22 of the compression device 9 supplied non-ionized extinguishing gas from the low pressure chamber 18.
  • the non-ionized extinguishing gas supplied to the compression volume 22 via the suction area 23 is not influenced by this.
  • this means that the compressed gas circuit breaker is characterized by an unchanged high breaking capacity even when it is switched on again quickly.
