  • Another of the disclosed valves is a fill valve 126 which is used after the breaker opening operation, so that gas can enter the second compression chamber 120 when the interrupting chamber 100 returns to the closed position.
  • valves for the discharge valve of the insulating gas in a high or medium voltage circuit-breaker breaking chamber one in which the valve is made of elastomer and the other in which the valve is made of metallic material.
  • the elastomer valve is in the form of a washer mounted freely in a passage. Its main advantages are not to induce significant pressure drop during the filling operation, to be reactive to the opening and closing.
  • the valve made of metallic material can take many forms.
  • a metal valve may be in the form of a washer mounted freely in a passage. It has the advantage of essentially being able to perform its functions of opening and closing tight regardless of the extreme temperature conditions.

  • a valve is used as a flexible metal blade, the opening being made by the elastic deformation of the blade.
  • the stop element allows the blade not to reach its breaking limit: this ensures a long life in operation compatible with the cycles of use of the circuit breaker that is equipped.
  • the flexibility conferred allows it to completely clear the channel through which the dielectric gas discharges, and thus not to induce a pressure drop for it.
  • valve closing calibration springs Because the reactivity to closure, of the order of a few microseconds, is naturally ensured by the intrinsic bending moment. at mounting with pinching of the base of the metal blade.
  • the valve according to the invention is perfectly suitable for use in a high-voltage circuit-breaker breaking chamber, since its operation is effective between -50 ° C. and 2500 ° C. under a pressure of up to 100 bars and has an endurance that can reach 10000 opening / closing cycles.
  • the body is of cylindrical revolution and comprises a plurality of through passages each defining a valve seat and distributed at the cylindrical periphery of the body, the valve comprising a plurality of abutment members integral with the body and as valve a single annular metal blade and one end of which is integral with the body and comprising flexible segments interposed individually between a valve seat and a stop element.
  • An alternative embodiment of this first mode is to provide the annular blade with an indexing pin allowing it to index angularly to the mounting each segment so as to be opposite one of the valve seats.
  • the body is of cylindrical revolution and comprises a plurality of through passages each defining a valve seat and distributed at the cylindrical periphery of the body, the valve comprising a plurality of abutment elements integral with the body and, as valves, a plurality of flexible metal blades, individually interposed between a valve seat and an abutment member and each with an integral end of the body.

  • the metal blade can advantageously constitute with a blade of elastomeric material a bi-flexible material assembly, the blade of Elastomeric material then obstructs with direct contact the valve seat in the closed position of the metal blade.
  • a seal of elastomeric material inserted into a groove in the body around the valve seat, the metal blade being in direct contact with the seal of elastomeric material in its closed position.
  • the elastomer used to form the bimaterial with the metal blade or the seal is of EPDM type (preferably of the methylene-propylene-diene class rubber), vulcanized with peroxides.

  • a self-inflating chamber is for example disclosed in the patent application. EP 1863054 .
  • the invention relates to a blow-off chamber of the self-blowing type comprising at least one discharge valve valve (s) described above.
  • a self-blowing chamber is for example described in the patent application FR 2821482 or in the patent application EP 2045827 described above.
  • the invention relates to a high-voltage circuit breaker greater than 52 kV and more particularly greater than 170 kV, comprising a breaking chamber provided with a valve valve (s) discharge described above.

  • the body 1 comprises a central bore 10 to fit and fix around a hollow actuating tube T fixed to the movable arc contact C1 of the interrupting chamber, as shown in FIG. figure 9 .
  • the discharge valve valve VC according to the invention is intended to discharge the dielectric gas of the volume V1 to the volume V2, when the pressure rises in the volume V1 under the action of the operating tube T via the blowing piston P fixed. In this breaking chamber represented in figure 9 the other contact C2 is fixed.

  • the valve seat 11 is defined at the end of the opening channel 12 formed in the valve body 1 and through which the gas from the volume V1 is intended to flow.
  • the choice can be made according to the conditions of use of the high or medium voltage circuit breaker. For example, if it turns out that at extreme low temperatures of use of the circuit breaker (typically up to T0 ⁇ - 50 ° C), direct metal / metal contact between the metal blade 2 and the valve body 1 is insufficient to ensure a dielectric gas seal, so the addition of a 5 or an elastomer blade 6, preferably EPDM type vulcanized with peroxides, can be realized.

  • This blade 2 comprises a number of six identical flexible segments 21 between them. All the segments 21 are interposed individually between a valve seat 11 and an abutment element 3. All the segments 21 are deformed in the same manner and they each follow the profile of the corresponding abutment element 3 in the extreme open position. ( Figures 2 and 2A ) and the corresponding passage 12 is completely clear.
  • the blade 2 comprises a pin 22 which allows the angular indexing of each segment 21 facing a through passage 12.
  • the flexibility and thus the opening torque of the metal blade 2 can be adjusted by the section S of the blade at the hinge portion ( figure 3 ). It is thus possible to size the section S, in other words the aperture 23, as a function of an overpressure of the gas present in the volume V1 with respect to the volume V2.
  • the choice of material and the dimensions of the metal blade 2 must also be determined according to the deformation of the desired blade 2 on opening and closing.
