Definitions

  • the invention relates to low-voltage circuit breakers with a sealed switching chamber according to the preamble of claim 1.
  • the actuating mechanism is arranged outside the switching chamber and is operatively connected to the movable contacts in the switching chamber through an opening in a partition of the switching chamber (DE-C-29 05 854).
  • the cover collar can only seal the switching chamber inadequately.
  • the invention is based on the object of improving the sealing of the switching chamber in a low-voltage circuit breaker of the type mentioned above.
  • the invention has the advantage that the sealing of actuating rods takes place via seals that are located on the selector shaft. Furthermore, the integration of the switching shaft in the switching chamber has the advantage that switches with a shallow depth can be built.
  • Fig. 1 two adjacent switching chambers 1, 2 are shown, the area of the switching chambers is shown in which the passage opening for the actuating rod is located in the switches of the previous type.
  • the housings of the switching chambers 1, 2 are composed of left and right shell halves 3, 4, 5, 6, which consist of electrically insulating material.
  • the control shaft 7 is shown in a shortened length in the area of the control chambers 1, 2.
  • the parts of the control shaft 7 which protrude from the control chambers are additionally sealed with protective caps 13, 14 from the switch space located in front of the control chambers 1, 2. With 15 in the switching chamber 2 in the right half of the shell recess for the switching shaft 7 is shown.
  • FIG. 2 shows the selector shaft clamps 8, 9 seated on the selector shaft, to which the actuating rods 11, 12 are fastened, via which the selector shaft 7 acts on the contact arms of the switch.
  • the selector shaft clamps 8, 9 are held in their axial position on the selector shaft 7 by means of spacer sleeves 10.
  • the torque transmission between the selector shaft 7 and the selector shaft clamps 8, 9 takes place via a hexagonal fit.
  • the selector shaft 7 is with the selector shaft clamps 8, 9 and the spacer sleeves 10 in matching semicircular recesses 15, 16, 17, 18 of the shell halves 3, 4, 5, 6 about their axis rotatably used sealing.

Claims (4)

  1. Disjoncteur de puissance à basse tension avec au moins une chambre de commutation (1, 2), un arbre de commande (7), avec au moins une paire de contacts séparables et un mécanisme d'actionnement pour l'ouverture et la fermeture du disjoncteur de puissance, caractérisé en ce que l'arbre de commande (7) est intégré dans des évidements semi-circulaires (15, 16, 17, 18) de la chambre de commutation (1, 2), les évidements semi-circulaires (15, 16, 17, 18) de la chambre de commutation (1, 2) sont chacun recouverts avec un capuchon de protection (13, 14) au niveau de la partie de l'arbre de commande (7) disposée dans la chambre de commutation et, en ce que l'étanchéité de la chambre de commutation (1, 2) est effectuée par des moyens d'étanchéité (8, 9, 10) qui se trouvent sur l'arbre de commande (7).
  2. Disjoncteur de puissance à basse tension selon la revendication 1, caractérisé en ce que le collier de l'arbre de commande (8, 9) et les douilles d'écartement (10) servent de moyens d'étanchéité, douilles qui sont appliquées par leurs surfaces d'enveloppe contre les surfaces des bords des évidements (15, 16, 17, 18).
  3. Disjoncteur de puissance à basse tension selon la revendication 1 ou 2, caractérisé en ce que l'étanchéité de la chambre de commutation (1, 2) avec l'arbre de commande intégré (7) s'effectue par l'intermédiaire de joints d'étanchéité en labyrinthe qui se composent des bords des évidements semi-circulaires (15, 16, 17, 18) et de rainures en encoche dans les moyens d'étanchéité (8, 9, 10).
  4. Disjoncteur de puissance à basse tension selon l'une des revendications 2 à 3, caractérisé en ce que la surface de l'arbre de commande (7) est complètement recouverte, pour l'isolation électrique, par les colliers (8, 9) de l'arbre de commande et par les douilles d'écartement (10).
