Definitions

  • the invention relates to a high-voltage circuit breaker with two arcing contact pieces, which are separated from one another in the event of a switch-off and between which an arc is drawn, if appropriate, in an arc space filled with an extinguishing gas, with the arc-heated quenching gas from the constriction of an insulating nozzle surrounding the arc space at least one outflow channel flows out, which has a plurality of areas successively passing through the extinguishing gas.
  • Such a high-voltage circuit breaker is known for example from DE-U 93 14 779.1 and DE-OS 29 47 957.
  • an arc is drawn between two arcing contact pieces in the event of a switch-off, which is blown by an extinguishing gas and is intended to be extinguished and prevented from reigniting.
  • a heating room is provided in which the quenching gas heated by the arc is stored under high pressure until the next current zero crossing of the current to be switched, in order to then flow back to the arc chamber when the pressure drops in the arc chamber and to cool the quenching gas there.
  • the extinguishing gas must then be able to flow through an outflow channel into an expansion space.
  • the extinguishing gas is cooled in a cooling device and deionized.
  • cooling devices have, for example, so-called mesh coolers in the form of perforated sheets and metal meshes, in which the interaction surface for the hot extinguishing gas is extremely large.
  • the cooling of the quenching gas also prevents ionized quenching gas from flowing into the switching path between the arcing contact pieces in a timely further switching process.
  • the present invention is therefore based on the object of creating a high-voltage circuit breaker of the type mentioned at the outset, in which an outflow behavior of the quenching gas through the outflow channel which is optimized with regard to arc quenching is achieved.
  • the first region facing the constriction of the nozzle has a reduced flow resistance compared to the constriction and that at least a second region, a third region and a fourth region are arranged downstream of the first region in the outflow direction of the extinguishing gas the specific flow resistance of the second and fourth areas is in each case greater than the specific flow resistance of the area immediately preceding in the outflow direction and that the specific flow resistance of the third Area is smaller than that of the second area.
  • the extinguishing gas flows, in each case with braking, through an area with greater specific flow resistance, and then in an area with lower specific flow resistance, which virtually forms an expansion volume, to expand.
  • the extinguishing gas pressure in the arc space can be controlled in terms of its time and thus an optimized pressure curve can be achieved for the arc extinguishing or the avoidance of re-ignition of the arc.
  • specific flow resistance is understood to mean the flow resistance for the extinguishing gas in relation to the unit of length in the flow direction.
  • the invention can advantageously be used in isolating nozzle switches which are equipped with a boiler room in which quenching gas heated by the arc can be stored under high pressure up to the zero crossing of the current to be switched.
  • a mechanical compression device for the extinguishing gas can be provided in the form of a compression piston and a compression cylinder.
  • An advantageous embodiment of the invention provides that each have a larger specific flow resistance having areas have cross-sectional constrictions of the outflow channel.
  • Such cross-sectional constrictions can be achieved, for example, by conically narrowing a tube surrounding the outflow channel, for example a tube carrying the continuous flow contact, or by thickening a bolt running centrally in the outflow channel.
  • a transmission for driving an arcing contact piece can also be provided in the outflow channel, for example if both arcing contact pieces are moved simultaneously by means of a common switch drive. The gear unit is then to be taken into account when calculating the outflow cross sections.
  • the regions each having a larger specific flow resistance can advantageously be designed as a nozzle.
  • Constrictions and nozzles in the outflow channel can each be formed by internals made of an insulating material, in particular polytetrafluoroethylene, or can also be coated with such a material.
  • a further advantageous embodiment of the invention provides that one of the regions with a greater specific flow resistance than the preceding region is designed as a radial deflection device for the extinguishing gas flow.
  • Such a radial deflection can be provided, for example, in the form of a nozzle, which deflects the extinguishing gas flowing axially in a radial direction or by more than 90 °.
  • a larger expansion space for the extinguishing gas can be provided behind the deflection device.
  • the invention can also be advantageously configured in that at least one of the areas with greater flow resistance is designed as a check valve or group of check valves.
  • the check valve (s) have a linearly movable plate closing an opening.
  • at least one of the check valves has at least one, in particular two, closure flaps which can be pivoted about a hinge.
  • the pivotable flaps can be pivoted almost completely out of the outflow channel in the forward direction, so that only a small increase in the specific flow resistance can be achieved.
  • the areas with a higher specific flow resistance are formed by bodies arranged in the outflow channel and having a plurality of through openings for the extinguishing gas.
  • Such bodies are understood to mean, for example, perforated sheets or metal mesh (mesh cooler).
  • the invention can also be carried out advantageously in that at least one region with a larger specific flow resistance is formed as a flow labyrinth.
  • At least one area with greater specific flow resistance is designed as a chamber with inlet openings and outlet openings, in which movable bodies, for example PTFE balls, are arranged in bulk.
  • the outflow channel extends from the nozzle constriction to a drive side and that at least one of the areas with greater specific flow resistance in the sense of the extinguishing gas flow is arranged downstream of a switch tube on the drive side which carries the arcing contact piece on the drive side.
  • Figures 1 to 8 show schematically in a longitudinal section a part of an interrupter unit of a high-voltage circuit breaker, the areas with greater specific flow resistance and with lower specific flow resistance in the outflow area on the side of the arcing contact piece designed as a contact pin being realized in different ways.
  • FIG. 1 shows part of an interrupter unit of a high-voltage circuit breaker with an insulating housing 1, which consists, for example, of porcelain or a composite insulator and in which two continuous current contacts 2, 3 are arranged.
  • the housing can also be designed as a grounded metal housing.
  • a movable and drivable arcing contact piece 4 is connected, the is designed as a tulip contact.
  • This arcing contact piece has radially resiliently arranged contact fingers on its circumference.
  • the drivable arcing contact 4 interacts with a fixed arcing contact 5 in the form of a contact pin. In the switched-on state, this passes through the constriction 6 of the insulating nozzle 7 and makes resilient contact with the drivable arcing contact piece 4.
  • an arc is drawn in the arcing space 9, which heats extinguishing gas located there, for example SF 6 (sulfur hexafluoride), so that it expands.
  • SF 6 sulfur hexafluoride
  • the expanded extinguishing gas is at least partly passed through a heating duct 10 into a heating room 11, where it is initially stored.
  • the alternating current to be switched passes zero, the arc 12 extinguishes and the quenching gas stored in the heating space 11 flows back through the heating channel 10 to the arc space 9, in order to prevent the arc from reigniting at the next voltage rise by cooling.

Le gaz d'extinction chauffé par l'arc électrique s'écoule dans au moins un canal d'écoulement (voir revendication 1) à partir du passage étroit (6) d'une buse isolante (7) entourant le compartiment d'arc électrique. Ce canal d'écoulement présente plusieurs zones (12,13,14,15) successivement parcourues par le gaz d'extinction. Selon l'invention, la première zone (12) faisant face au passage étroit de la buse (12) présente une résistance spécifique à l'écoulement réduite par rapport à celle du passage étroit (6) et la première zone (12) est suivie dans le sens d'écoulement du gaz d'extinction d'une deuxième zone (13), d'une troisième zone (14) et d'une quatrième zone. La résistance spécifique à l'écoulement de la deuxième zone et celle de la quatrième zone sont respectivement supérieures à la résistance spécifique à l'écoulement de la zone immédiatement en amont dans le sens d'écoulement. Enfin, la résistance spécifique à l'écoulement de la troisième zone (14) est inférieure à celle de la deuxième zone (13).
