Abstract

QUE COMPRENDE: a) UN TRANSFORMADOR PRINCIPAL QUE TIENE UN DEVANADO SECUNDARIO CON MULTIPLES TOMAS, DONDE CADA TOMA PROPORCIONA UN VOLTAJE; b) MULTIPLES INTERRUPTORES CONECTADOS A LAS TOMAS PARA SELECCIONARLAS, TALES COMO UN INTERRUPTOR DE CONTACTO OPERADO DE MANERA MECANICA Y UN INTERRUPTOR CON BASE DE SEMICONDUCTOR; c) UN FUENTE DE VOLTAJE CONTROLABLE, ACOPLADA DE MANERA QUE SU SALIDA SE AGREGA O SUSTRAE RESPECTO DEL VOLTAJE SELECCIONADO; Y, d) UN TRANSFORMADOR AUXILIAR PARA ACOPLAR (c) A UNA O MAS TOMAS SELECCIONADAS, QUE TIENE UN DEVANADO PRIMARIO Y UNO SECUNDARIO CON UNA TOMA CENTRAL QUE SUMINISTRA EL VOLTAJE DE CA A LA CARGA. EL VOLTAJE A TRAVES DE (b) SE MINIMIZA ANTES DE CERRAR EL INTERRUPTOR, Y LA CORRIENTE A TRAVES DE (b) SE MINIMIZA ANTES DE ABRIR EL INTERRUPTOR. LA SALIDA DE (c) ESTA CONECTADA AL DEVANADO PRIMARIO DE (d), UN PRIMER SUBCONJUNTO DE (b) CONECTADO A TOMAS ALTERNATIVAS ESTA CONECTADO A UN LADO DEL DEVANADO SECUNDARIO DE (d), Y UN SEGUNDO SUBCONJUNTO DE (b) CONECTADO A TOMAS ALTERNATIVAS ADYACENTES ESTA CONECTADO AL LADO OPUESTO DEL DEVANADO SECUNDARIO DE (d). ADEMAS SE REFIERE A UN METODO PARA VARIAR EL VOLTAJE DE CA QUE INCLUYE: i) AUMENTAR EL VOLTAJE HASTA EL VOLTAJE DIFERENCIAL ENTRE LA TOMA SELECCIONADA Y UNA TOMA ADYACENTE; ii) CERRAR EL INTERRUPTOR CONECTADO A LA TOMA ADYACENTE; iii) ABRIR EL INTERRUPTOR CONECTADO A LA TOMA SELECCIONADA; iv) DISMINUIR EL VOLTAJE DE (c) HASTA ALCANZAR CERO VOLTIOS; Y, v) INVERTIR LA POLARIDAD DEL VOLTAJE DE (c)
