Abstract

Dispositif fusible limiteur de courant caractérisé en ce qu'il comporte une enveloppe externe remplie d'une huile isolante froide, un corps cylindrique étanche dans lequel a été scellé un élément fusible creux avec un agent de suppression d'arc et qui est immergé dans ladite huile isolante froide et, une paire de supports métalliques conducteurs, servant de bornes, couplés conductivement à l'élément fusible creux et fixés aux deux extrémités dudit corps cylindrique, l'une des extrémités de chaque support étant fixee au corps cylindrique de façon à laisser passer l'huile isolante froide au travers d'un alésage interne traversant de part en part l'élément fusible creux, l'autre extrémité faisant saillie de l'enveloppe externe.
