Abstract
INTERRUPTEUR DE CIRCUIT A DISPOSITIF DE DECLENCHEMENT MAGNETIQUE A GRANDE VITESSE. LE DISPOSITIF DE DECLENCHEMENT ELECTROMAGNETIQUE SELON L'INVENTION COMPREND UNE PIECE POLAIRE AYANT UNE SECTION TRANSVERSALE EN FORME D'U ET CHEVAUCHANT LE TRAJET DES CONDUCTEURS TRAVERSANT CE DISJONCTEUR, ET UNE ARMATURE FEUILLETEE MOBILE QUI EST COUPLEE MAGNETIQUEMENT A LA PIECE POLAIRE ET A UNE EPAISSEUR NOTABLEMENT PLUS GRANDE QUE L'EPAISSEUR DE LA PIECE POLAIRE. AVEC L'AGENCEMENT SELON L'INVENTION, L'ARMATURE EST SOUMISE PENDANT LES SITUATIONS DE DANGEREUSES SURCHARGES DE COURANT, A UNE FORCE D'ATTRACTION PRODUITE PAR LE FLUX MAGNETIQUE DANS LA PIECE POLAIRE ET ENCORE ACCRUE, AVEC TOUT ACCROISSEMENT DE COURANT FAISANT SUITE A LA SATURATION DE LA PIECE POLAIRE, PAR UNE FORCE ELECTRODYNAMIQUE PRODUITE ENTRE L'ARMATURE ET LESDITS CONDUCTEURS.
