Patent

CA 2331013

The invention concerns a low voltage multipole circuit breaker (10) with high electrodynamic resistance comprising a box made of insulating material, subdivided into a front compartment (12) housing a control mechanism (24) for opening and closing the circuit breaker and a rear compartment (14) separated from the front compartment by an intermediate wall (20). The rear compartment (14) is itself subdivided into elementary compartments (36) by separating partitions (38), each elementary compartment (36) housing one of the circuit breaker poles (56). The control mechanism (24) is linked to a pole shaft (78) common to the whole set of poles (56). The pole shaft (78) is located in the rear compartment (14) and is supported by bearings passing through the partition walls.

Un disjoncteur multipolaire (10) basse tension de tenue électrodynamique élevée comporte un boîtier en matériau isolant, subdivisé en un compartiment antérieur (12) de logement d'un mécanisme de commande (24) de l'ouverture et de la fermeture du disjoncteur et un compartiment postérieur (14) séparé du compartiment antérieur par une paroi intermédiaire (20). Le compartiment postérieur (14) est lui-même subdivisé en compartiments élémentaires (36) par des cloisons de séparation (38), chaque compartiment élémentaire (36) logeant l'un des pôles (56) du disjoncteur. Le mécanisme de commande (24) est lié à un arbre des pôles (78) commun à l'ensemble des pôles (56). L'arbre des pôles (78) est localisé dans le compartiment postérieur (14) et supporté par des paliers traversant les cloisons de séparation.
