Abstract (en)
The circuit-breaker includes main contacts (26, 30) and a vacuum canister (38) in parallel which ensures disconnection, the whole being contained in an enclosure (10) filled with sulphur hexafluoride. The canister is designed for dielectric holding in this gas. The contacts of the canister (38) are of a refractory material and a coil generates an axial magnetic field in the region of the arc. <IMAGE>

Le disjoncteur comporte des contacts principaux (26,30) et une cartouche à vide (38) en parallèle qui assure la coupure, l'ensemble étant contenu dans une enceinte (10) remplie d'hexafuorure de soufre. La cartouche est conçue pour la tenue diélectrique dans ce gaz. Les contacts de la cartouche (38) sont en un matériau réfractaire et une bobine engendre un champ magnétique axial dans la zone de l'arc. <IMAGE>
