Abstract

LA PRESENTE INVENTION CONCERNE LES EXTINCTEURS ELECTROMAGNETIQUES D'ARC POUR APPAREILS DE COMMUTATION. L'EXTINCTEUR COMPORTE UNE CHAMBRE D'EXTINCTION D'ARC 1 FABRIQUEE A PARTIR D'UN MATERIAU ISOLANT ELECTRIQUEMENT, DANS LAQUELLE EST PRATIQUE UN CANAL AXIAL 2 ET DEUX ELECTRODES 3, 4 DISPOSEES SUIVANT L'AXE DE LA CHAMBRE 1, ET DESTINEES A FORMER L'ARC D'EXTINCTION 5 COURBE SUIVANT UNE HELICE. LA CHAMBRE D'EXTINCTION D'ARC IMPOSE UN MOUVEMENT A L'ARC D'EXTINCTION 5 DANS LA DIRECTION RADIALE ET POSSEDE UNE ENCEINTE COURBEE SUIVANT UNE HELICE. LE PAS DE CETTE ENCEINTE HELICOIDALE EST INFERIEUR AU DIAMETRE DE LA CHAMBRE D'EXTINCTION D'ARC 1 DANS LA SECTION TRANSVERSALE. APPLICATION: COMMUTATION DE CIRCUITS ELECTRIQUES.THE PRESENT INVENTION CONCERNS ELECTROMAGNETIC ARC FIRE EXTINGUISHERS FOR SWITCHING APPARATUS. THE FIRE EXTINGUISHER INCLUDES AN ARC EXTINGUISHING CHAMBER 1 MANUFACTURED FROM AN ELECTRICALLY INSULATING MATERIAL, IN WHICH AN AXIAL CHANNEL 2 AND TWO ELECTRODES 3, 4 ARE PRACTICED, FOLLOWING THE AXIS OF CHAMBER 1, AND INTENDED FOR FORM THE EXTINGUISHING ARC 5 CURVE FOLLOWING A PROPELLER. THE ARC EXTINGUISHING CHAMBER IMPOSES A MOVEMENT ON THE ARC EXTINGUISHING 5 IN RADIAL DIRECTION AND HAS A CURVED ENCLOSURE FOLLOWING A PROPELLER. THE PITCH OF THIS HELICOIDAL ENCLOSURE IS LESS THAN THE DIAMETER OF ARC EXTINGUISHING CHAMBER 1 IN THE CROSS SECTION. APPLICATION: SWITCHING OF ELECTRIC CIRCUITS.
