Title (EN) ELECTRICAL TRANSFORMER WITH WINDINGS
(FR) TRANSFORMATEUR ÉLECTRIQUE À ENROULEMENTS
Abstract:
(EN) The invention relates to an electrical transformer (T, T') comprising: a primary central winding (11a) extending around an axis (X) and configured to generate a central magnetic flux when a current is passed through it circulating in a first direction around the axis (X), two peripheral primary windings (12a, 13a) extending around the axis (X), between which the central primary winding (11a) is located, and configured to generate peripheral magnetic fluxes when currents are passed through same respectively circulating in a second direction around the axis (X) which is opposite to the first direction, the peripheral magnetic fluxes superimposing on the central magnetic flux, wherein the windings are further configured in such a way that the peripheral magnetic fluxes compensate the central magnetic flux in the regions located beyond the peripheral windings.
(FR) II est proposé un transformateur électrique (T, T') comprenant : un enroulement primaire central (11a) s'étendant autour d'un axe (X) et configuré pour générer un flux magnétique central, lorsqu'il est parcouru par un courant tournant selon un premier sens autour de l'axe (X), deux enroulements primaires périphériques (12a, 13a) s'étendant autour de l'axe (X), entre lesquels l'enroulement primaire (11a) central est localisé, et configurés pour générer des flux magnétiques périphériques lorsqu'ils sont parcourus par des courants respectifs tournant selon un deuxième sens autour de l'axe (X) qui est opposé au premier sens, les flux magnétiques périphériques se superposant au flux magnétique central, dans lequel les enroulements sont en outre configurés de sorte que les flux magnétiques périphériques compensent le flux magnétique central dans des régions localisées au-delà des enroulements périphériques.
