Definitions

  • the invention relates to a high voltage circuit breaker with extinguishing gas under pressure, the elements filled with gas can be assembled and disassembled without loss of gas, the circuit breaker comprising a gas regenerating element the replacement of which can also be carried out without loss. gas.
  • High-voltage circuit breakers generally include at least two superimposed insulating columns assembled by bolting, one delimiting a breaking chamber, the other containing an operating rod. These columns are filled with a pressurized dielectric gas such as sulfur hexafluoride (SF6).
  • SF6 sulfur hexafluoride
  • Circuit breakers of the aforementioned type require the presence of a gas regenerating element, since the latter undergoes, at each power outage, a deterioration in its dielectric qualities which can lead to dangerous degradation for the performance of the circuit breaker.
  • FIG. 1 schematically and partially in axial section, a pole of circuit breaker with self-blowing SF6 gas according to a known technique.
  • the pole includes a breaking chamber 2 closed at the ends by a plate 2A and a casing 5, and an insulating support 3 closed at the ends by bottom plates 3A and 6.
  • a molecular sieve 4 is placed between the casing 5 of the chamber 2 and the bottom plate 6 of the support 3.
  • the gas exchange SF6 between the chamber 2 and the support 3 is done through the molecular sieve 4 by the passages 7 of the casing 5 of the chamber 2, and 8 of the base plate 6 of the support 3.
  • the operation of the circuit breaker is obtained from a jack 9 supplied by an energy source allowing the alternating movement up and down of a piston 10 connected to a blowing device 11 of the chamber 2 by an insulating rod 12 and a rod 13 of the movable contact 21 coupled together by a device 14.
  • the fixed contact is referenced 22.
  • the two chambers of the chamber 2 and of the support 3 are sealed by the seals 15, 16, 17, 18, 19 and 20 In this type of circuit breaker, the assembly and disassembly as well as the replacement of the molecular sieve 4 cannot be done without the loss of SF6 gas and without air intake.
  • circuit breaker as defined in claim 1 appended hereto meets these objectives.
  • FIG. 2 represents a partial axial section of a circuit breaker according to the invention
  • column 2 breaking chamber
  • column 3 support
  • the molecular sieve 4 is placed in a cylindrical container 40, the end faces of which are provided with openings such as 41, 42, 43 and 44.
  • the container is placed in a housing 45 of the plate. end 6 which closes the support column 3.
  • the housing 45 communicates, through an opening 46 in the bottom 6, with the interior of the column 3.
  • the opening 46 is made in line with the openings 41 and 42 to allow, when the circuit breaker is assembled, a circulation of the gas through , the molecular sieve.
  • valve is pushed by a spring 53 resting on a fixed stop 54 secured to the plate 6.
  • the container 40 is in contact with the valve by a rod 50A forming an integral part of the valve.
  • the housing 45 is provided with a seal 56 cooperating with the container.
  • This valve cooperates with the casing 5.
  • the latter is a complex part comprising an end 5A in the form of a crown intended to bear in leaktight manner on the plate 6, a cylindrical part 5B serving in particular for housing the molecular sieve, one end 5C constituting a blowing piston and a cavity 5D serving as a housing for a spring 61 for actuating the valve.
  • the cavity 5D communicates with the outside through an opening 64 whose role will be explained later.
  • the valve 60 has a rod 60A intended to come into contact with the container during the assembly of the circuit breaker.
  • the casing 5 has a cavity 5E intended to serve as a housing for the upper part of the container. This cavity 5E is provided with a seal 65.
  • the casing 5 has an end ring 5F provided with a seal 66 intended to cooperate with a bearing surface 57 of a circular groove 58 formed in the end plate 6.
  • the seal at the passage of the rod 13 is ensured by the seal 63; the latter, sandwiched between a portion 60A in the form of a ring of the valve 60 and a step 5G of the casing 5, is elastically deformed and comes to bear against the rod 13 (FIG. 3).
  • the chamber 3 is closed in leaktight manner by the valve 50 pushed by the spring 53 against the seal 52 and by the seal 51 pressed against the rod 12.
  • the columns are brought vertically to one another, as shown in FIG. 2 and the rods 12 and 13 are secured by bolts 67.
  • the container 40 of the molecular sieve is placed in its housing 45.
  • Figure 4 shows the final phase of the operation.
  • the O-ring 66 is placed on the bearing surface 57 of the bottom plate 6 thus ensuring the complete sealing of the two assembled columns.
  • the seals 55 and 65 provide a seal around the container promoting the circulation of gas through the screen.
  • the assembly operation is completed by tightening the bolts 59 and 69.
  • each valve 2 to 6 equidistant rods (such as 60A, 60B, 50A, 50B) on valves 60 and 50 and passages (such as 64, 64A, 46, 46A) around the rods respectively in the casing 5 of the chamber 2 and in the bottom plate 6 of the support 3.
  • equidistant rods such as 60A, 60B, 50A, 50B
  • passages such as 64, 64A, 46, 46A
