Abstract

L'invention concerne un coupe-circuit sous vide Selon l'invention, il comprend deux électrodes circulaires de contact 12 et 14 disposées face à face, au moins l'une des électrodes comprenant une partie centrale circulaire et plane 20 et une partie effilée 22 s'étendant radialement vers l'extérieur à partir du pourtour externe de la partie plane, des gorges 24 passant radialement vers l'extérieur à partir de l'intérieur de la partie plane et centrale et se terminant sur le pourtour externe de la partie effilée, ces gorges ayant des extrémités disposées dans la partie plane et centrale, et un moyen pour entraîner un arc électrique formé sur la partie plane lors de la séparation des électrodes de contact, vers le pourtour externe de la partie effilée. L'invention permet notamment d'obtenir des coupe-circuit pouvant fonctionner à toutes les gammes de courantThe invention relates to a vacuum circuit breaker According to the invention, it comprises two circular contact electrodes 12 and 14 arranged face to face, at least one of the electrodes comprising a circular and flat central part 20 and a tapered part 22 extending radially outward from the outer periphery of the planar portion, grooves 24 extending radially outward from the interior of the planar central portion and terminating at the outer periphery of the tapered portion , these grooves having ends arranged in the flat and central part, and a means for driving an electric arc formed on the flat part during the separation of the contact electrodes, towards the outer periphery of the tapered part. The invention makes it possible in particular to obtain circuit breakers which can operate at all current ranges.
