Definitions

  • the present invention relates to a pressurized dielectric gas circuit breaker of the type comprising a compression volume and a thermal volume.
  • compression volume is meant a volume whose gas is pushed by a piston and directed on the arc which forms during the separation of the arcing contacts.
  • the subject of the invention is a pressurized dielectric gas circuit breaker of the type comprising fixed main contacts, fixed arcing contacts, a mobile assembly comprising main contacts and arcing contacts, a blowing device comprising a semi cylinder. -mobile separated by a fixed piston into first and second chambers, the first of which communicates with a blowing nozzle, and a thermal volume opening onto the separation zone of the fixed arcing contacts and the arcing contacts of the mobile assembly, characterized in that a communication is established between the thermal volume and said second chamber to allow the gas heated by the arc in the thermal volume to help the displacement of the cylinder and the compression of the gas of the first bedroom.
  • a fixed assembly comprising a substantially tubular metal assembly 3 connected to a fixed block 4 electrically connected to an outlet not shown.
  • the tube 3 has at its end a thinned part 6 terminated by an insulating part or made of metal resistant to the arc.
  • the tube 3 is also provided at its end with a. metal part 11 constituting the fixed main contact of the circuit breaker, and of an insulating blowing nozzle 12.
  • the blowing volume 15 of the circuit breaker is delimited by a portion 3A of the external surface of the tube 3, by a semi-mobile cylinder 16 and by a ring 3B surrounding the tube 3 and forming a piston.
  • the crown 3B and the tube 3 preferably constitute a single piece coming from machining.
  • the cover 20 and the fingers 21 are fixed to a ring 22B machined from the tube 22.
  • the circuit breaker works as follows:
  • the energy of the arc contributes to forcefully move the semi-mobile equipment to compress the blowing volume.
  • FIG. 5 shows that the semi-mobile assembly can be placed on the mobile assembly.
  • the elements common to this figure and to the preceding figures have been given the same reference numbers with the addition of a premium (') and the references of the fixed and mobile assemblies have been swapped.
  • the spring 25 then comes into abutment on a ring 22 'coming with the tube 22.
  • Figure 6 is an alternative embodiment in which the passages 36 are closed by valves such as 36A, opening only in the direction from volume 9 to volume 35. In this way the energy of thermal origin contained in the gas heated by the arc remains inside the volume 35 and is. entirely used to assist in the compression of the volume 15. In addition, the hot gas does not disturb the blowing by the fresh gas.
  • the breaking chamber comprises an arcing contact 41, tubular and semi-mobile; semi-mobile means that the tube can make a certain displacement compared to the tube 3.
  • the circuit breaker works as follows:
  • a primary arc A ' (see fig 9) is established between the fingers and the tube, and generates a very strong pressure in the volume 9. This pressure is communicated by the passages 36 to the volume 35 and thus promotes the compression of the blowing volume 15 for the extinction of the arc A.
  • the overpressure in the volume 9 is eliminated by the calibrated holes 45.
  • the 3D valve opens making it easier to fill the volume 15.
  • the valve 16C opens on tripping and allows, when cutting small currents, to avoid creating a vacuum in the volume generated for the movement of 16. In the event of a large current the overpressure due to the arc closes this valve.
  • FIGS 10 to 12 illustrate an alternative embodiment of the invention.
  • the tubes 50 and 54 delimit a thermal volume 56. This chamber is closed by an insulating part 57 defining with the nozzle an annular blowing channel 60.
  • a semi-mobile cylinder 61 terminated by a bottom 62 surrounds the tube 50.
  • the tube 61 slides in leaktight fashion on a first crown 50A (coming from molding or forging with tube 50).
  • a spring 63 is disposed between the crown 50A and the bottom 62; the room delimited by the elements 50, 50A, 61 and 62 is designated by 64.
  • a tubular insulating cover 65 extends the cylinder 61. It defines with the bottom 62 the tube 50 and a second ring 50B, a blowing chamber 66.
  • the chamber 64 communicates with the thermal volume 56 by passages 67 made in the tube 50.
  • the blowing chamber 66 communicates with the annular blowing channel through passages 68.
  • the movable assembly comprises a tube 70, the end 70A of which constitutes the movable arcing contact and contact fingers 71 protected by a cover 72.
  • circuit breaker The operation of the circuit breaker is identical to that described with reference to FIGS. 1 to 4.
  • a valve 62A opens, favoring the filling of the chamber 66.
  • the invention applies to high voltage circuit breakers (greater than 45 kV) and to medium voltage.
