Definitions

  • the invention relates to the field of high-voltage circuit breakers under metal tanks, type GIS (Gas Insulated Switchgear) or Dead tank type. These circuit breakers can be part of a metal enclosure.
  • GIS Gas Insulated Switchgear
  • Dead tank type can be part of a metal enclosure.
  • the invention relates more particularly to a method for evacuating the hot gases generated by a break in such a circuit breaker and the associated circuit breaker structure.
  • the hot gases i.e., plasma and exhaust gases
  • the hot gases can promote reboots between the various live cut-off parts and the parts connected to the earth such as the metal tank.
  • a first type of arrangement for example provided on Japanese type circuit breakers, such as that disclosed in the patent application JP2003217411 , comprises a short tube implanted at the outlet of the nozzle blowing hot gases and which also makes it possible to blow these directly into the metal tank.
  • the dielectric insulation is obtained by maintaining great distances between the discharge ring formed with the tube and the metal tank.
  • a second type of arrangement for example provided on the "Dead tank” as published in the patent application EP1806760 , allows to have a volume of dielectric gas present in the metal part of the exhaust sufficiently large to absorb all the hot gases generated during the longest arc period of the maximum short-circuit current.
  • This exhaust arrangement includes lateral openings on the side through which the hot gases escape into the interior of the metal vessel.
  • the first type referred to above encloses volumes of insulating gas which are by construction less than the amount of hot gases blown during a break. Therefore, larger overall dimensions of the metal tank than the second type are provided because these hot gases are discharged in an uncontrolled manner, and therefore dimensional safety margins must be taken to ensure dielectric strength to the tank.
  • the closure provided in the arrangement of the second type involves a sufficient volume to keep the hot gases inside the metal part of the exhaust. Also, the dimensional safety margin between the outside of the exhaust and the metal tank can be reduced.
  • EP1185996B1 discloses an exhaust structure with an alternation of means for varying the section through which the hot gas flow passes on its exhaust path and thus cool before its exit to the longitudinal end of the surrounding contact tube the fixed arc contact.
  • EP-A-1 768 150 discloses a method and a circuit breaker according to the preambles of claims 1 and 2.
  • the object of the invention is to further reduce the overall dimensions of the exhaust or evacuation of hot gases and also to further reduce the dimensions of the metal vessel.
  • Another object of the invention is to provide a hot gas evacuation solution which has satisfactory cooling while maintaining a satisfactory purge of the cutoff gases between the arcing contacts.
  • the object of the invention is a process according to Claim 1, namely a method for evacuating hot gases from a break in a high-voltage circuit breaker, comprising a tank metal filled with insulating gas, an envelope comprising gas outlet openings and arranged inside the metal vessel communicating through the openings.
  • insulating gas is sucked from the inside of the casing, parallel to all the hot gas flows from the cut, so as to mix them inside the casing, before their evacuation. through the gas outlet openings of the casing and towards the inside of the metal tank.
  • insulating gas present before cut-off is used in the circuit breaker exhaust structure, a gas which by definition is colder than the hot gases from the cut-off and blends with said hot gases before they escape. towards the inside of the tank.
  • the cold insulating gas already present in the exhaust is simply pushed into the interior of the metal tank by the hot gases, which therefore undergo no cooling by mixing with the insulating gas.
  • the invention is particularly interesting for very large fault currents, i.e. maximum fault currents and the longest arc durations.
  • the invention also relates to a high voltage circuit breaker according to claim 2, particularly adapted to the implementation of the method according to the invention.
  • the deflector (s) thus provided within the scope of the invention thus force the insulating gas, sucked from the opening passage, to be completely deflected and to flow parallel to the flow of hot gases generated by blowing before their subsequent mixing inside the envelope and their exit through the openings provided.
  • the gas outlet openings are made at one of the longitudinal ends of the envelope.
  • the opening passage comprises a plurality of holes distributed uniformly at the periphery of the sheath.
  • two deflectors coaxial with respect to the axis of translation of the moving contact are provided, one of the two baffles comprising at least one indentation made at one of its ends. longitudinal, the arrangement formed between the casing, the sheath and the two baffles creating a baffle insulating gas supply by the notch.
  • One of the two arcing contacts is fixed to the casing and the other is movable in translation along the axis.
  • the two arc contacts are movable in translation along an axis.
  • a variant which is not part of the invention, finally relates to a circuit breaker module as described above, which comprises the casing, the sheath and the baffles.
  • modules are advantageous because they are of a lower cost of implementation because, in particular, the molding of parts is reduced and the assembly between the different parts is simplified.
  • the module comprising six metal parts has the advantage of having simpler moldings.
  • a circuit breaker 1 is shown in a metal envelope (GIS).
  • This high-voltage circuit breaker 1 comprises a metal tank 2 filled with an insulating gas (GI), an envelope 3 comprising gas outlet openings 30.
  • the envelope is arranged inside the metal tank and communicates with the gas outlet openings for evacuating insulating or hot gases (GI and GC represented by the arrows). More exactly, in this embodiment according to the figure 1 , the gas outlet openings are made at the periphery of the casing 3 near its longitudinal end 3b which is closest to the cutoff zone.
  • the circuit breaker 1 also comprises a pair of arcing contacts of which only the fixed contact 40 is represented ( figure 1 ) and is fixed to the casing 3.
  • the other movable contact in translation along the axis XX ' is integral with an insulating nozzle 41 provided for blowing hot gases generated during the separation of the contacts.
  • the suction means 5 comprise a sheath 50 surrounding the fixed contact 40 and arranged inside the casing 3 by defining a through passage 6 via a plurality of through holes 500 distributed uniformly to the
  • the suction means also comprise a single deflector in the form of a tubular portion 51, arranged inside the sheath, so that the hot gases (GC) suck insulating gas (GI) from the holes 500, that is to say exclusively from inside the casing 3, the baffle 51 deflects the insulating gas (GI) sucked parallel to the flow of hot gases.
  • GC hot gases
  • GI insulating gas
  • the arrangement of the deflector 51 in the sheath 50 is thus provided so that only the insulating gas (GI) coming from the inside of the casing 3 is sucked up and not for example the gases at the periphery of the nozzle 41. Then, the insulated and deflected insulating gas mixes with the hot gases inside the casing 3.
  • GI insulating gas
  • the hot gases GC leaving the nozzle 41 at high speed can suck the insulating gas, colder, respectively, from the outside of the exhaust (that is to say between the sleeve 50 and the envelope 3 ), through the portion of the gas return passage (i.e. from the bowl 3a to the side openings) and then through the through holes 500.
  • the gas outlet openings 30 are made at one of the longitudinal ends 3a of the casing 3 and the suction means comprise two baffles 51, 52 coaxial with the axis XX 'of translation of the movable contact and of the nozzle 41, one of the two deflectors 52 comprising a plurality of notches 520 made at one of its longitudinal ends 52a, the arrangement formed between the casing, the sleeve and the two baffles 51, 52 creating a baffle 7 insulating gas supply by the notches 520 (see bent arrows on Figures 2A and 2C for example).
  • one of the two baffles 51 comprises two parts of the walls 510, 511 parallel to each other.
  • the other deflector 52 is arranged between these two parts of the walls 510, 511 parallel so that the insulating gas supply baffle, or suction baffle 7, is shaped in Z with the interior of the sleeve 50 parallel to the wall 511 (see for example the Figure 2A ).
  • the module 8 according to the invention is obtained from six metal parts interleaved and screwed together. Of these, three pieces are molded. One forms a cover 80 including the gas outlet openings 30. The other part 81 forms part of the sheath 50 with a base 50A to which the fixed arcing contact can be fixed, and a part 511 of one of the two deflectors 51. The last molded part comprises another part 510 of the deflector 51 in which the nozzle 41 can slide. Finally, three tubular pieces respectively form the envelope 3, the other part of the sleeve 50 and the other deflector 52, each made from a rolled sheet.
  • the module 8 'according to the invention is obtained from five metal parts nested and screwed together. Of these, two pieces are molded ( FIG. 3A and FIG. 3B ). One forms a lid 80 'comprising the gas outlet openings 30 ( figure 3A ). The other part 81 'forms part of the sleeve 50 with a base 50A to which the fixed arc contact 40 can be fixed. The other part comprises integrally one of the two baffles 51, a part 510 in which the insulating nozzle can slide. Finally, three tubular pieces respectively form the envelope 3 ( figure 3C ), the other part of the sleeve 50 ( 3D figure ) and the other baffle 52 ( figure 3E ), each made from a rolled sheet.
  • the suction means 5 which are provided in the different embodiments are mechanical means which, as arranged in the metal vessel, consist in producing a suction of all the hot gases by the cold insulating gases.
  • the mechanical means provided deflector (s)
  • the mechanical means provided can define paths traveled on the one hand, by the hot gases from the blowing nozzle to the outlet of the tank and other on the other hand, by the cold insulating gases from their suction inlet (baffle inlet 7 in the embodiment of the figure 2 ) to the outlet of the tank which are approximately the same length.
  • the invention shortens the exhaust of a high-voltage circuit breaker, which also reduces the longitudinal size of the associated metal vessel. This is particularly important in order to meet the transport requirements, before their installation in-situ, tanks called "Dead Tank".
