Definitions

  • the present invention relates to a blast gas circuit breaker, comprising a cylindrical insulating or metallic envelope filled with dielectric gas under pressure, a fixed arcing contact and a movable assembly connected to an operating member comprising a blowing cylinder associated with a blowing nozzle and cooperating with at least one piston, a movable arcing contact extending a tubular part inside the blowing cylinder associated with a neck of section smaller than the inside section of the tubular part and coaxial with it.
  • circuit breakers are known (see for example US-A-4,939,322).
  • the tubular part carrying the movable arcing contact is often opened by lateral openings in order to obtain a double blowing in the sense that the gas compressed in the annular space between the blowing cylinder and the tubular part supporting the contact the movable arc is blown on the one hand inside the blowing nozzle but also on the other hand towards the interior of the movable arc contact and therefore inside the tubular part supporting it.
  • the present invention proposes to improve the breaking of such a circuit breaker in particular, thermal expansion circuit breakers using the energy of the arc, by increasing the gas pressure near the movable arcing contact by means of an arrangement. particularly simple and inexpensive.
  • the circuit breaker according to the invention is characterized in that said neck is a bottleneck of the gas flow carried by the internal wall of the tubular part, the minimum cross section of the bottleneck being of a diameter less than or equal to the diameter of the inner section of the movable arcing contact and greater than or equal to 0.75 times the diameter of the inner section of the movable arcing contact.
  • the distance between the movable arcing contact and the neck throttle is slightly greater than the penetration length of the fixed arcing contact inside the tubular part, in the engaged position.
  • the neck can be formed from an insert.
  • the bottleneck is, according to a preferred constructive measure, consisting of a deformed part of this covering.
  • the single figure shows in longitudinal section a partial view of a circuit breaker.
  • the moving element is shown in the open position and the gas is blown by the piston 7 according to the arrows shown, on the one hand in the blowing nozzle 6 and on the other hand in the tubular part 8 carrying the movable arcing contact 9.
  • This gas is then evacuated through at least one opening provided near the not shown end of the tubular part 8.
  • This tubular part 8 is provided near the contacts 9 with a bottleneck formed by a deformed part 10 of the metal tube 11, generally made of steel, which protects the tubular part 8 against the effects of the high temperature.
  • This part 10 deformed symmetrically with respect to the longitudinal axis of the tubular part 11 is spaced from the movable arcing contacts 9 by a distance d.
  • This distance d is preferably slightly greater than the penetration length of the fixed arcing contact 3 introduced into the movable arcing contact 9 in the engaged position. of the circuit breaker.
  • 0.75 d o ⁇ d 1 ⁇ d o do being the diameter of the internal section of the arcing contact 9 and d1 the minimum diameter of the passage section of the bottleneck.
  • the figure shows a preferred form of the bottleneck, allowing optimal gas flow conditions.
  • This neck can be of any other shape, biconical or other.
  • the bottleneck can be produced by fixing an insert on the internal wall of the part 8 supporting the movable arcing contact 9.
  • This insert can be metallic, for example steel or insulating, for example in "Teflon".
  • the invention applies to high-voltage circuit breakers of the conventional type with an insulating casing or of the type with a metal casing grounded.
