Definitions

  • the present invention relates to a dielectric blast gas circuit breaker and more particularly to a medium voltage circuit breaker, in which a current of high intensity (several thousand amps) flows.
  • This type of circuit breaker is found in power plants, at the output of the alternator and upstream of the step-up transformer.
  • a circuit breaker is known according to the preamble of claim 1, for example from document FR-A-1 458 334.
  • the permanent movable contact through which the permanent current passes, is most often a copper tube of relatively high mass which, when tripped, is driven with the arcing contact, at high speed. .
  • the energy necessary for this maneuver is important since it is proportional to the product of the mass of the moving assembly by the square of the speed of movement of this crew. All manufacturers seek to reduce this operating energy because its importance penalizes the cost price of the control of the switching device.
  • An object of the invention is to provide a circuit breaker in which both the mass and the speed of movement when the movable contact is triggered are reduced compared to those of the contact of the prior art, while maintaining a high speed of movement arcing contacts.
  • this is obtained by the circuit breaker as defined by claim 1 by separating the movable main contact from the movable assembly and by making the movable main contact by means of a short element associated with a displacement means communicating on triggering a speed lower than that of said moving assembly.
  • the circuit breaker partially represented in FIG. 1, in half-section of axis xx, comprises an insulating envelope 1 delimiting a volume 2 filled with a gas with good dielectric properties such as sulfur hexafluoride (SF6) under a pressure of a few bars.
  • a gas with good dielectric properties such as sulfur hexafluoride (SF6) under a pressure of a few bars.
  • the fixed assembly includes a fixed main contact consisting of fingers 3 and a fixed arcing contact consisting of a tube 4 having an end 4A of an alloy resistant to the effects of the arc, for example a tungsten-based alloy. Contacts 3 and 4 are connected to a first socket not shown.
  • the fixed assembly further comprises a crown of fingers 6 carried by a crown fixed 7. The fingers 6 carry, internally at the crown, an annular stop 8. The fixed crown is electrically connected to a second socket not shown.
  • the fixed crown 7 carries a tube 9 machined, of axis xx, which ends in a piston 10, provided with a one-way valve 11, a seal 12 and sliding electrical contacts 13.
  • the moving element comprises an arcing contact consisting of a tube 15, of axis xx, having one end 15A of material resistant to the effects of the arcing.
  • This tube 15 is integral with a coaxial tube 16, with which it defines a blowing cylinder moving around the fixed piston 10.
  • the seal between the piston 10 and the cylinder 16 is ensured by the seal 12; the flow of current between the tube 15 and the piston 10 is ensured by the sliding contacts 13.
  • the tube 16 carries a blowing nozzle 17 made of insulating material.
  • the tubes 15 and 16 are advantageously produced in the same machined part; holes 18, formed in the part connecting the two tubes, make it possible to establish communication between the volume 20 and the volume 21 comprised between the tube 15 and the nozzle 17.
  • the tube 15 is extended by a part 22 connected to an operating rod, not shown. Holes 15B in the tube 15, and 9A in the tube 9, allow, when the circuit breaker opens, the evacuation of the hot gas to the volume 2.
  • the movable main contact is constituted by a short metal cylinder 30 cooperating with the fingers 3 and 6.
  • This cylinder is fixed to the end of a tube 31 terminated by a ring 32.
  • the tube could be replaced by a set of rods arranged according to certain generatrices of a cylinder).
  • a spring 33 bandaged when the circuit breaker is in the engaged position (FIG. 1), is disposed between the annular stop 8 and the ring 32.
  • the tube 30 leaves the fingers 3 at a lower speed (V1) which is that given by the energy of the spring 33.
  • the rest of the opening operation (arc blowing) is done as in well-known arc blowing circuit breakers.
  • the valve 11, by opening, avoids any effect of depression in the volume 20, during the engagement.
  • a spring has been given as an example of means for implementing the movable main contact; another possibility is to use a lever game linked to the moving assembly and the production of which is well known to those skilled in the art.
  • circuit breakers provided with means for creating a secondary arc which comes to aid in the blowing of the arc and / or in the tripping operation.

Claims (4)

  1. Schalter mit einem dielektrischen Gas zum Ausblasen des Lichtbogens, mit einem ortsfesten Hauptkontakt (3), einem ortsfesten Lichtbogenkontakt (4) und beweglichen Organen, die mit einem Steuerschaft gekoppelt sind und einen beweglichen Lichtbogenkontakt (15-15A) sowie einen bezüglich eines ortsfesten Kolbens (10) verschiebbaren Blaszylinder (16) aufweisen, wobei der Schalter weiter einen beweglichen Hauptkontakt (30) enthält, der mit den beweglichen Organen nicht fest verbunden ist und ein kurzes zylindrisches Element bildet, das beim Schließen des Schalters mit dem ortsfesten Hauptkontakt (3) zusammenwirkt, dadurch gekennzeichnet, daß die beweglichen Organe unmittelbar mit dem Steuerschaft verbunden sind, während der bewegliche Hauptkontakt (30) beim Öffnen des Schalters von einem Mittel angetrieben wird, das ihm ursprünglich eine geringere Geschwindigkeit als die der beweglichen Organe verleiht.
  2. Schalter nach Anspruch 1, dadurch gekennzeichnet, daß der bewegliche Hauptkontakt (30) ein Rohr ist.
  3. Schalter nach Anspruch 1, dadurch gekennzeichnet, daß der bewegliche Hauptkontakt (30) von Stangen gebildet wird, die entlang gewisser Mantellinien eines Zylinders verlaufen.
  4. Schalter nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß das Mittel zum Antrieb des beweglichen Hauptkontakts eine Feder (33) ist, die sich mit einem ersten Ende an einem festen Anschlag (8) und mit einem zweiten Ende an einem Anschlag (32) abstützt, der mit dem beweglichen Hauptkontakt (30) fest verbunden ist.
