Definitions

  • the present invention relates to a circuit breaker with high voltage including for each pole, an envelope cylindrical filled with insulating gas inside which the cut-off members and a resistor are arranged, axially arranged, associated with means for its temporary insertion when closing the circuit breaker.
  • a first object of the invention is to provide a circuit breaker of the aforementioned type in which the means resistance are reduced, which allows reduce the power of the control.
  • Another object of the invention is to provide a circuit breaker of the aforementioned type in which the means resistance are reduced in volume, which reduces the diameter of the envelopes used.
  • the present invention relates to a circuit breaker according to the claims.
  • reference 1 designates an envelope insulating, for example ceramic, filled with a gas good dielectric properties such as hexafluoride sulfur SF6.
  • the breaking chamber includes a fixed assembly comprising a fixed metal cylinder 2 connected to a first socket not shown.
  • Resistance 3 said "closing” is disposed axially in the envelope 1; it consists of a stack of 3A discs surrounded by a lateral insulating sheath 4; a first end of the stack is connected to the first socket of current mentioned above; the other end of the stack is terminated by a metal flange 6.
  • a metal tube 7 constituting the fixed main contact of the circuit breaker; at same cylinder 2 is fixed, by metal arms 8, a metallic tubular portion 9 whose end 9A is made of an alloy resistant to the effects of the arc electric.
  • This tubular portion 9-9A constitutes the arcing contact, fixed, of the circuit breaker.
  • the flange 6 is fixed, preferably by screws 10, a metal part 11 carrying metal arms 12 parallel to the axis of the envelope; the arms are from preferably two in number; at the end of these arms is welded a metal crown 13 constituting an electrode fixed for insertion of the closing resistance.
  • the mobile circuit breaker assembly includes a flange circular metal 15 arranged perpendicular to the axis of the envelope.
  • This metallic flange wears a crown of contact 16 constituting the main mobile contacts which cooperate with the tube 7.
  • the fingers 16 are protected by a 16A corona hood.
  • the flange is connected to two coaxial cylinders whose common axis is the axis of the envelope. These cylinders, referenced 17 and 18, define a blowing volume V1 in which a piston is arranged not shown.
  • One of the cylinders, the inner cylinder 17 for example, is mechanically connected to an operating rod not shown; the other cylinder, 18, is electrically connected by non-sliding contacts shown, to a second outlet not shown.
  • the inner cylinder 17 extends on the other side of the flange 15 by a cylindrical portion 17A provided internally of sliding contacts 17B.
  • the cylindrical portions 17A and 20 define a volume annular V2 in which the end of a nozzle moves blowing 22 made of insulating material.
  • the nozzle 22 has, like conventional breaker nozzles, a 22A neck, but it ends with a crown 22B constituting a shoulder facilitating its sliding in volume V2.
  • a spring 24 rests on the one hand on the shoulder 22B and on the other hand on a shoulder 20A at the end of the cylindrical portion 20.
  • the nozzle 22 is secured by a crown 26 to a metallic tubular portion 30 constituting an arcing contact semi-mobile cooperating with the fixed arcing contact 9-9A.
  • the portion 30 is terminated at one end by a piece of 30A contact made of an alloy resistant to the effects of the electric arc.
  • the flange 15 has passages 15A for the passage of the blowing gas from volume V1 to volume V2 during an opening operation.
  • the circuit breaker works as follows.
  • the circuit breaker In normal operating conditions, the circuit breaker is in the configuration of Fig. 1.
  • the permanent current goes through the first socket, cylinder 2, the tube 7, the fingers 16, the flange 15, the tube 18 and the second outlet.
  • the tripping of the circuit breaker is produced by the displacement of the mobile assembly, under the action of the circuit breaker control, not shown, to the right of Fig. 1.
  • a first phase represented in Fig. 2, the mobile assembly has moved a few tens of mm to the right.
  • the sub-assembly semi-mobile constituted by the nozzle (22) and the arcing contact (30-30A) remains in the position they occupied in the configuration of FIG. 1. This allows at main contacts 7 and 16 to separate, the current switching in the arcing contacts 9-9A and 30-30A. In this movement, the spring 24 is compressed.
  • the contacts 16 After an additional run of the moving crew, the contacts 16 have passed the insertion electrode 13, and arcing contacts 9-9A and 30-30A are about to break separate, since the spring being fully compressed, the arcing contact 30-30A of the semi-movable subassembly is driven by the mobile assembly.
  • the pressure in volume V2 decreases rapidly and, under the effect of the spring, the semi-mobile sub-assembly constituted by the nozzle 22 and the arcing contact 30-30A resumes its initial position relative to the mobile assembly.
  • the circuit breaker is, in the tripped position, in the configuration of Fig. 5.
  • the voltage is held between the ends of the contacts 9A and 30A, as well as between the end of the corona covers 16A and electrode 13, thanks to isolation distances sufficient.
  • the distance between the end of the cover (16A) of the movable main contact (16) and the electrode (13) is less than the distance between the ends respective 9A and 30A of the arcing contacts 9 and 30. It is this feature which will allow temporary insertion resistance during the closing operation of the breaker.
  • a closing operation results in a movement of the moving part to the left.
  • the distance between the respective ends of 9A and 30A of arcing contacts becomes less than the insulation distance (Fig. 7), an arc begins between these contacts, which has the consequence of shorting the resistance 3.
  • the dimensions of the various elements of the circuit breaker and the value of the moving speed of the moving assembly are chosen so that the insertion time is between 8 and 10 milliseconds, which is the range prescribed by network users.
  • the mobile assembly regains its initial position (Fig. 1).
