Abstract

Perfectionnement applicable aux transformateurs à circuit magnétique horizontal préférablement de section rectangulaire. Chaque flasque de serrage est formé d'une juxtaposition de poutres longitudinales : d'une part des poutres latérales 4 comportant des tôles magnétiques sur chant sur presque toute leur épaisseur, d'autre part des poutres intermédiaires 5 ne comportant des tôles magnétiques sur chant que sur une partie de leur épaisseur, le complément étant constitué par un fer plat longitudinal 15, chaque assemblage de bandes de tôle magnétique comporte en son milieu une cale longitudinale en forme de coin et sur chaque flanc un autre fer plat longitudinal de même largeur. L'invention s'applique plus particulièrement aux transformateurs cuirassés à cuve en cloche de grande puissance.
