Definitions

  • the invention relates to a compressed gas circuit breaker a first, drivable arcing contact, a second, fixed arcing contact, one concentric to these running nominal current path with a first, drivable Nominal current contact and a fixed nominal current contact as well as with a compression device that has a Filling valve with a radially arranged outside the nominal current path Low pressure space is connectable, at least the first, drivable arcing contact formed in a ring is and is carried by a switching tube, via the outlet Switching gases resulting from the switch-off process Outflow volume reach that provided radially to the switching tube Blow-out openings in connection with the low pressure chamber stands.
  • Such a pressure gas circuit breaker goes with regard its contact arrangement and formation, the first being drivable Arcing contact is annular and is carried by a switching tube, via which the switch-off process resulting switching gases into an outflow volume get, which is a low pressure space, for example essentially from DE-OS 25 32 088.
  • the Contact arrangement associated with a compression device can be connected to the outflow volume via a filling valve, as is apparent from DE-OS 26 18 087.
  • the invention is based on the problem of a compressed gas circuit breaker according to the preamble of claim 1 create, in the case of a quick restart the on Filling valve of the compression device pending for subsequent switch-off process required, non-ionized Extinguishing gas not through the result of a switch-off process ionized and contaminated switching gas contaminated becomes.
  • This creates a spatial separation of the additionally created Suction area of the outflow volume by this is partitioned off from the suction area by a partition, the one with the inner wall of the, especially as a fixed Compression cylinder trained nominal current path firmly connected is.
  • the partition is expediently designed as a hood, the one with its cylindrical area with the inner wall the nominal current path by a welding, soldering or Adhesive connection can be connected.
  • the partial view of a compressed gas circuit breaker is in section shown and half each in with respect to the switch axis 1 in the on and in the off position.
  • the compressed gas circuit breaker essentially from a first drivable arcing contact 2, a second, fixed arcing contact 3, one concentric with this running 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 provided. This is above a check valve 8 with a compression device 9 in connection.
  • the first, drivable arcing contact 2 is with an insulating nozzle body 10 connected, the one with the arc room 11 the boiler room 7 after initiation of a switch-off process Connectable gas channel 12, which in the arc room 11 flows into.
  • the arcing contact is as a tulip contact is formed and carried by a switching tube 13, which is connected to the shift rod 14.
  • Via outlet openings 17 within the nominal current path 4 this extinguishing gas is arranged radially outside of the nominal current path 4 Low pressure chamber 18 supplied.
  • this extinguishing gas as ionized extinguishing gas before it is fed into the Low pressure chamber 18, which is on its outer circumference by a Insulating body 19 is limited, is the nominal current path 4 in the area of the discharge openings 17 from one Baffle 20 surround, which is at a distance from the exhaust openings 17 is arranged.
  • the drawing also shows that immediately the cylinder bottom 21 of the compression volume 22 of the compression device 9 connects a suction area 23 which likewise via openings provided radially in the nominal current path 4 24 communicates with the low pressure chamber 18.
  • the cylinder base 21 also has the pressure relief valve 29 on - via the suction area 23 to the compression volume 22 the compression device 9 from the low pressure chamber 18 supplied non-ionized extinguishing gas.
  • the compression volume 22 Non-ionized extinguishing gas supplied via the suction area 23 unaffected. But that means that the compressed gas circuit breaker even with a quick restart characterized by an unchanged high breaking capacity.
