Abstract

L'invention concerne un dispositif d'extinction d'arc à isolement gazeux, notamment de SF6. Il comporte un dispositif à autosoufflage 28 à dépression formé par un ensemble piston 24, cylindre 26 confinant une chambre d'aspiration 34 du gaz contenu dans l'enceinte 14 étanche. Le canal interne 36 du contact mobile 18 Creux est traversé par un écoulement de gaz de soufflage pour l'extinction de l'arc 30 tiré entre les contacts 16, 18 séparés. Un embout 38 annulaire en matériau isolant est associé à l'extrémité du contact mobile 18 pour empêcher la migration radiale des racines d'arc vers l'extérieur du canal 36. Application : sectionneur sous charge à dépression.
