Abstract

L'invention concerne un transformateur électrique comportant de manière connue un élément central tubulaire dénommé caniveau muni ou non à ses extrémités de rebords périphériques et autour duquel sont disposés transversalement les enroulements du bobinage du transformateur tandis que le circuit magnétique de ce dernier est réalisé par un empilage de tôles magnétiques feuilletées qui ont des formes appropriées et qui sont entôlées de manière telle qu'une partie de celles-ci constitue un noyau à l'intérieur du caniveau et que l'autre partie des rôles réalise une carcasse extérieure qui encadre ledit caniveau. Ce transformateur est remarquable en ce qu'il comporte de chaque côté ouvert du caniveau au moins une patte de fixation munie d'un prolongement d'assujettissement qui est serré entre la partie des tôles du circuit magnétique constituant le noyau et paroi interne du caniveau. L'invention concerne aussi son procédé de fabrication.
