Abstract

L'INVENTION CONCERNE LES TRANSFORMATEURS. LES BOBINES SONT CONSTITUEES DE BANDES CONDUCTRICES ENROULEES EN SPIRALE. ELLE SE FONT FACE DE MANIERE COAXIALE ET PRODUISENT DES DEPLACEMENTS DE COURANT DUS A LA REPULSION ENTRE LES DEUX CHAMPS ELECTRIQUES. LES BOBINES SONT SEPAREES DANS LE BUT DE FAVORISER LA DISPERSION DU FLUX MAGNETIQUE. APPLICATION AUX TRANSFORMATEURS A GRANDE PENTE STATIQUE.THE INVENTION CONCERNS TRANSFORMERS. THE COILS ARE CONSTITUTED OF CONDUCTIVE STRIPS WOUND IN A SPIRAL. THEY ARE FACED COAXIAL WAY AND PRODUCE CURRENT DISPLACEMENTS DUE TO REPULSION BETWEEN THE TWO ELECTRIC FIELDS. THE COILS ARE SEPARATED FOR THE PURPOSE OF PROMOTING THE DISPERSION OF THE MAGNETIC FLOW. APPLICATION TO LARGE STATIC SLOPE TRANSFORMERS.
