Definitions

  • the present invention relates to a switching chamber of a high voltage switch with a heating volume according to the preamble of claim 1.
  • the invention also relates to a switch with such a switching chamber.
  • This value corresponds to a density value which is achieved with a heating volume which is greater from the beginning, but whose volume would be too great to produce an extinguishing gas pressure when switching off small to medium currents, which has a sufficient magnitude for successful arc blowing.
  • FIGURE shows a plan view of a guided along an axis section through a designated for a gas-insulated high-voltage switch switching chamber according to the invention, in which the switching chamber is shown above the axis with the switch closed and below the axis when opening the switch.
  • the left end of the arcing contact 4 is inserted in an electrically conductive manner into the right end of the tubular arc contact 3.
  • the two arc contacts 3, 4 separate from each other and this forms a footing on the two ends of the arcing contacts arc L, which generates in the arc zone 8 hot high pressure gases.
  • the temperature and pressure of the arc gases are determined by the arc work and are therefore proportional to the duration of the arc current determined by the current zero crossing and approximately the square of the current to be switched off.

Claims (10)

  1. Chambre de coupure pour un interrupteur haute tension à isolation à gaz, comprenant un boîtier (1) rempli de gaz d'isolation, dans lequel sont disposés deux contacts d'arc électrique (3, 4) déplaçables l'un par rapport à l'autre le long d'un axe (A), un volume de chauffage (6) entourant coaxialement les deux contacts d'arc électrique pour recevoir du gaz d'extinction comprimé provenant d'un espace d'arc électrique (8) et un espace (12) pour recevoir le gaz d'extinction détendu, une partie de la paroi du volume de chauffage (6) étant formée par un piston (9) qui peut coulisser à l'encontre d'une force de rappel (F), caractérisée en ce que le piston (9) est réalisé sous la forme d'un piston différentiel et présente, du côté opposé au volume de chauffage (6) un étage de piston qui forme une première surface de travail (A2) agissant dans l'espace de détente (12) et une deuxième surface de travail (A1 - A2) agissant dans un espace d'accumulateur (13) rempli de gaz d'isolation, et en ce qu'un canal reliant le volume de chauffage (6) à l'espace d'accumulateur (13) est guidé à travers le piston (9) et est ouvert lorsque la pression du gaz d'isolation (p2) dans l'espace d'accumulateur (13) est supérieure à la pression du gaz d'extinction (p1) dans le volume de chauffage (6).
  2. Chambre de coupure selon la revendication 1, caractérisée en ce que la première surface de travail (A2) est dimensionnée de telle sorte qu'au-dessus d'une valeur limite de la pression de gaz d'extinction (p1) régnant dans le volume de chauffage (6), la force de rappel (F) soit inférieure à une force opposée provenant de la différence entre la pression du gaz d'extinction (p1) et la pression de gaz (p0) dans l'espace de détente (12).
  3. Chambre de coupure selon la revendication 2, caractérisée en ce qu'un ressort de pression (10) agissant sur le piston (9) est disposé dans l'espace d'accumulateur (13) pour produire la force de rappel (F).
  4. Chambre de coupure selon la revendication 3, caractérisée en ce que le ressort de pression (10) est disposé dans l'espace de détente (12) au lieu de l'espace d'accumulateur (13).

    p1 étant la pression de gaz produite par le travail d'un arc électrique de coupure (L) dans le volume de chauffage (6),
    p0 étant la pression de gaz dans l'espace de détente (12), et
    A2 étant la dimension de la première surface de travail (A2) .
  6. Chambre de coupure selon l'une quelconque des revendications 1 à 5, caractérisée en ce que la première surface de travail (A2) est formée par une saillie de piston s'étendant axialement (91) et en ce que l'espace de détente (12) contient un espace partiel orienté axialement (16), dans lequel est guidée, de manière coulissante, la première surface de travail (A2) .
  7. Chambre de coupure selon la revendication 6, caractérisée en ce que la saillie de piston (91) est réalisée sous forme tubulaire, et en ce que l'espace partiel (16) présente un volume réalisé sous forme de cylindre creux.
  8. Chambre de coupure selon la revendication 7, caractérisée en ce que la surface extérieure du cylindre creux est formée par un tube métallique (17) limitant le volume de chauffage (6) vers l'extérieur et la surface intérieure est formée par la buse d'isolation (5).
  9. Chambre de coupure selon l'une quelconque des revendications 1 à 8, caractérisée en ce que dans une liaison prévue entre l'espace d'accumulateur (13) et l'espace de détente (12) est disposé un clapet anti-retour (15), qui est bloqué lors de la génération d'une surpression dans l'espace d'accumulateur (13).
  10. Interrupteur haute tension comprenant une chambre de coupure selon l'une quelconque des revendications 1 à 9.
