Abstract
Perfeccionamientos en transformadores polifásicos, que comprenden un número de núcleos magnéticos igual al número de fases, teniendo cada uno de los núcleos dos lados rectilíneos adyacentes cada uno de los cuales dispuesto contra un lado rectilíneo de un núcleo magnético próximo y pasa por un bobinado que comprende arrollamientos de alta tensión de sección recta trapezoidal y de baja tensión de sección recta rectangular, siendo cada núcleo magnético simétrico con respecto al plano de simetría de dos bobinados adyacentes, y estando impregnado de un barniz o de una resina, caracterizados porque los núcleos magnéticos son serrados en dos partes según un plano perpendicular a su plano de simetría, siendo a continuación reunidas entre sí las dos partes, y porque se fabrican a partir de chapas magnéticas de al menos dos anchuras diferentes, de modo a presentar una sección recta que comprende al menos un escalón o grada.
