Abstract

Afin de contrer la répulsion générée entre les contacts d'une ampoule à vide (16) par exemple lors du passage d'un courant de défaut, l'appareil de coupure (10) est associé à un solénoïde (32) de sorte que les efforts électrodynamiques créés par le passage du courant entre ses spires entraînent une contre-réaction qui maintient les contacts (12, 14) de l'ampoule (16) fermés. Notamment, le solénoïde (32) est couplé de façon rigide à l'ampoule (16) à une extrémité (34), et à une tige (22) d'actionnement du contact (12) à l'autre (36), de sorte que sa compression lors du passage du courant de défaut entraîne un des contacts (12).
