Abstract

EL TRANSFORMADOR DE CIERRE DEBE SER PUESTO EN FUNCIONAMIENTO PARA PASAR DE LA FASE DE CIERRE A LA FASE DE TRANSUITO, SI SU TRANSFORMADOR ES TOTALMENTE DESIMANTADO. CON LA ENTRADA A ESTE ESTADO LAS TENSIONES DEL TRANSFORMADOR INTERCAMBIAN SU POLARIDAD. DE ESTA MANERA LA DESMAGNETIZACION SOLO POUEDE LLEVARSE A CABO CON AYUDA DE UN DETECTOR DE ALCANCE PLENO (22). DEBIDO AL INEVITABLE SONIDO DEL TRANSFORMADOR, SE PRODUCEN EN LA FASE DE CIERRE RETENCIONES PARASITARIAS QUE DEBEN SER ELIMINADAS. PARA ESTE INVENTO SE PROPONE UN TIEMPO (T) DE ELIMINACION DE ESTAS RETENCIONES. CON TENSIONES MINIMAS EL TIEMPO T ES MAS LARGO Y CUANDO LA TENSION HA ALCANZADO EL PUNTO CULMINANTE, EL TIEMPO T ES MAS BREVE O ES IGUAL A 0. DE ESTA MANERA SE IGNORAN DE FORMA FIABLE TODOS LOS CAMBIOS PREVISTOS, Y TAMBIEN SE APREHENDEN CON SEGURIDAD TODAS LAS RETENCIONES DESMAGNETIZADAS
