Abstract

Sistema para suministro de energía eléctrica variable trifásico alimentado por energía alterna trifásica, y que tiene un autotransformador regulable de tres devanados conectado en estrella a través de las líneas de transporte de energía y la provisión de un primer neutro, teniendo dicho autotransformador medios de toma asociados con cada uno de sus devanados para conectar de manera regulable a diferentes vueltas de aquellos, un transformador de suministro que tiene un primario de tres devanados, estando conectados los extremos correspondientes de dichos devanados primarios a dichos medios de toma, respectivamente, caracterizado en que los medios de conmutación se han suministrado para proporcionar un segundo neutro y servir para la conmutación de los extremos opuestos de los devanados del primario entre el segundo neutro y las líneas de transporte de energía para efectuar cambios entre las diferentes condiciones de la energía de salida del transformador de suministro, con lo cualen la gama elevada de energía de salida variable la corriente en los devanados del primario y el autotransformador se mantiene constante entre las condiciones de delta completa y estrella completa a un valor igual al 42% menos que el de la corriente de línea.
