Claims (12)

  1. Interrupteur pour un fonctionnement multipolaire avec une chambre de commutation, une chambre de commutation partielle (1, 2) étant prévue par pôle, la chambre de commutation comportant un pont de commutation mobile (35) qui s'étend à travers les chambres de commutation partielles (1, 2), une pièce de commutation de pont (30) étant prévue pour chaque chambre de commutation partielle (1, 2) dans le pont de commutation et les pièces de commutation de pont étant agencées à une certaine distance l'une de l'autre le long d'une direction d'extension principale du pont de commutation (35) et la direction d'extension principale du pont de commutation (35) étant orientée globalement perpendiculairement à un axe de déplacement du pont de commutation (35), les pièces de commutation de pont (30) s'étendant globalement perpendiculairement à la direction d'extension principale du pont de commutation (35), caractérisé en ce que des pièces de commutation fixes (10a, 10b, 20a, 20b) sont agencées parallèlement à la direction d'extension principale du pont de commutation et en ce que les chambres de commutation partielles (1, 2) sont agencées symétriquement l'une par rapport à l'autre.
  2. Interrupteur selon la revendication 1, caractérisé en ce que les chambres de commutation partielles (1, 2) sont cloisonnées électriquement contre l'action d'arcs électriques du pôle de l'autre chambre de commutation partielle respective.
  3. Interrupteur selon l'une des revendications précédentes, caractérisé en ce que chaque chambre de commutation partielle (1, 2) comporte deux pièces de commutation fixes (10a, 10b, 20a, 20b) avec une première zone de contact (11) par pièce de commutation, les pièces de commutation de pont (30) déplaçables avec le pont de commutation (35) et électriquement conductrices comportant à chaque fois deux deuxièmes zones de contact (31) pour l'établissement d'une liaison électriquement conductrice entre les premières et les deuxièmes zones de contacts (11, 31) et pour la séparation des premières et des deuxièmes zones de contact (11, 31).
  4. Interrupteur selon l'une des revendications précédentes, caractérisé en ce que, pour au moins l'une des chambres de commutation partielles (1, 2), il est prévu au moins deux dispositifs d'extinction (61) pour l'extinction d'arcs électriques qui peuvent apparaître lors de la séparation des premières et des deuxièmes zones de contact (11, 31).
  5. Interrupteur selon l'une des revendications précédentes, caractérisé en ce que, pour au moins l'une des chambres de commutation partielles (1, 2), il est prévu au moins quatre dispositifs d'extinction (61) pour l'extinction, indépendante de la polarité, d'arcs électriques qui peuvent apparaître lors de la séparation des premières et des deuxièmes zones de contact (11, 31).
  6. Interrupteur selon l'une des revendications 4 ou 5, caractérisé en ce que des premiers conducteurs d'arcs électriques (12) s'étendent à partir des premières zones de contact (11) en direction des dispositifs d'extinction (61, 62) et des deuxièmes conducteurs d'arcs électriques (32) s'étendent à partir des deuxièmes zones de contact (31) en direction desdits dispositifs d'extinction.
  7. Interrupteur selon la revendication 6, caractérisé en ce que la distance des premiers conducteurs d'arcs électriques (12) aux deuxièmes conducteurs d'arcs électriques (32) augmente en direction des dispositifs d'extinction (61) respectifs.
  8. Interrupteur selon l'une des revendications précédentes, caractérisé en ce qu'un dispositif à aimant permanent est prévu pour former un champ magnétique largement homogène dans les zones entre les premières et les deuxièmes zones de contact (11, 31) et les dispositifs d'extinction (61) respectifs.
  9. Interrupteur selon la revendication 8, caractérisé en ce que le dispositif à aimant permanent comporte au moins deux aimants (51) en forme de plaques, les aimants (51) étant agencés sur des côtés longs des chambres de commutation partielles (1, 2), à chaque fois au voisinage des zones de contact (11, 31).
  10. Interrupteur selon l'une des revendications 8 ou 9, caractérisé en ce que le dispositif à aimant permanent comporte deux plaques polaires (55) parallèles, les plaques polaires (55) étant assemblées l'une à l'autre par un ou plusieurs aimants permanents (57) en un profilé globalement en forme de U.
  11. Interrupteur selon l'une des revendications 4 à 10, caractérisé en ce que les dispositifs d'extinction (61) sont conçus comme des chambres de désionisation, avec un empilement de tôles isolées électriquement les unes par rapport aux autres avec à chaque fois un entrefer entre deux tôles voisines.
  12. Interrupteur selon l'une des revendications 4 à 10, caractérisé en ce que les dispositifs d'extinction sont formés par un agencement de niches avec des parois en matière isolante, des niches individuelles étant largement cloisonnées les unes par rapport aux autres par des parois de niche (45) et/ou des parois de cloisonnement (46) et des ouvertures de soufflage étant agencées à chaque fois sur une paroi côté extérieur.
