Definitions

  • a control body insulated against the contacts is arranged on the inner contact (contact pin). This extends from the contact area of the inner contact along the axis of the contacts against or in the outer contact (contact tulip).
  • the arc zone created when the switch is broken surrounds the control body.
  • the arc zone has approximately the shape of a hollow cylinder, which improves the energy transfer to the walls.
  • the energy can be delivered both to the inner wall (i.e., the control body) and to the outer wall. As a result, the radiation load on the walls is halved for a given arc intensity.
  • the removal rate dm / dt of the wall material is against
  • FIG. 3 shows the switch according to FIG. 1 in a second phase when the switch is interrupted
  • the quenching chamber 5 communicates via a
  • the operation of the switch of FIG. 1 is apparent from the turn-off operation shown in Fig. 2 and 3.
  • the outer contact 2 with the switch body 4 along the axis 1 from the inner contact 3 with the control pulled body 9 away.
  • an arc zone 10 between the contacts extends around the control body 9 and thus has approximately the shape of a hollow cylinder. To the outside it is bounded by the inside of the switch body 4, inwardly from the control body 9.
  • the arc carries from both bodies of material, resulting in a pressure build-up. Since the mouth 11 of the quenching channel 6 is arranged at the arc zone 10, gas can flow from the arc zone 10 into the quenching chamber 5.
  • control body 9 additionally has a third section 9c, which is arranged on the side of the second section 9b facing the inner contact 3.
  • the diameter of the third portion is smaller than that of the second portion 9b.
  • This embodiment is particularly suitable for high currents, in which at the beginning of the interruption process, when the third section 9c is in the region of the mouth 11, a rapid pressure build-up can take place.
  • the second section (which may have a slightly larger diameter than that shown in FIGS. 1-3) in the region of the mouth 11, makes it more difficult for the extinguishing gas to escape at an early stage.
  • the first section 9a reaches the orifice, so that the quenching gas can escape virtually unhindered and extinguish the arc.

Abstract

Dans un disjoncteur à autosoufflage, le contact interne (3) est équipé d'un corps de commande (9) qui s'étend dans le contact externe (2), ou plus précisément contre ce dernier. Le corps de commande (9) contraint l'arc électrique dans une zone (10) d'arc en forme de cylindre creux. Il en résulte une montée en pression plus rapide, ce qui permet d'améliorer le chargement de la chambre d'extinction d'arc (5) du disjoncteur en gaz d'extinction d'arc. La forme adaptée du corps de commande (9) permet d'optimiser le flux de gaz sortant dans la zone (10) d'arc électrique ou entrant dans ladite zone.
