Abstract

El sistema de conexión de transformadores trifásicos de potencia, con mando electrónico, que evita las sobrecorrientes de conexión que se producen cuando se alimenta a un transformador trifásico, es un conjunto compuesto de interruptor convencional multipolar y tres interruptores unipolares a base de componentes de estado sólido (triacs) de forma que para dar alimentación a un transformador trifásico se dan impulsos de disparo a los triacs de forma secuencial, primero a dos de ellos en el momento adecuado y un cierto tiempo después al tercero. Después de un corto tiempo se cierra el interruptor convencional y luego deja de darse impulsos de disparo a los triacs.
