Abstract
L'invention concerne un dispositif de protection contre les tensions anormales triphasées. Le dispositif comprend un boîtier 10 mis à la masse, trois électrodes 20a, 20b disposées à des intervalles angulaires égaux concentriquement au boîtier, et une pile de résistances non linéaires 14a, 14b reliée par une extrémité à chacune des électrodes et par une autre extrémité au bord périphérique du fond du boîtier 10 en étant radialement écartée vers l'extérieur. L'invention permet d'améliorer la durée de vie de ces dispositifs de protection.
