Abstract

Perfeccionamientos en trasformadores de tensión continua, especialmente para la alimentación de consumidores que pueden originar un cortocircuito o de consumidores que se alimentan con una corriente constante, con un transformador con un arrollamiento primario y dos arrollamientos secundarios, estando colectado el arrollamiento primario a través de un primer elemento de conmutación a la tensión de alimentación, mientras que arrollamiento secundario alimenta al circuito de corriente de consumidores y otro arrollamiento secundario (arrollamiento de mando) mantiene abierto al elemento de conmutación en el circuito primario en la fase de bloqueo y le mantiene conductor en la fase de flujo de corriente, caracterizados porque en el circuito de corriente primaria del transformador está incluido un elemento de medición de corriente cuya caída de tensión por encima de un valor predeterminado de la corriente primaria, conecta a un segundo elemento de conmutación que por su parte ejerce un efecto de mando adicional sobre el primer elemento de conmutación en el circuito de corriente primaria.
