Abstract

SE PROPONE UN PROCESO PARA LA CONDUCCION DE CORRIENTE EN UNA DISPOSICION DE SOLDADURA DE RESISTENCIA, ESPECIALMENTE EN UNA INSTALACION DE PUNTOS MULTIPLES. LA GRADUACION DE LA CORRIENTE PRIMARIA SE CONSIGUE MEDIANTE TIRISTORES A TRAVES DE UNA CONDUCCION DE ENTRADA DE FASE. CON ARREGLO AL PROCEDIMIENTO, SE MIDE EN CADA SEMICICLO DE LA TRACCION PRIMARIA (30), EL RETRASO DE FASE (32) EXISTENTE ENTRE LA CORRIENTE PRIMARIA I (31) Y LA TRACCION PRIMARIA (30). EL VALOR HALLADO PARA EL RETRASO DE FASE SE COMPARA CON EL VALOR PREVISTO PARA EL SIGUIENTE ANGULO DE ENCENDIDO DEL TIRISTOR. SI EL VALOR DEL RETRASO DE FASE (32) FUERA MAYOR QUE EL ANGULO DE ENCENDIDO PREVISTO, SE CONFIRMARA EL ANGULO DE ENCENDIDO PREVISTO; EN CASO CONTRARIO, SE PONDRIA UN NUEVO ANGULO DE ENCENDIDO DEPENDIENTE DEL VALOR DEL RETRASO DE FASE (32). PARA CALCULAR EL ANGULO DE ENCENDIDO (ALFA) SE DETERMINA CONVENIENTEMENTE, LA SUPERFICIE DE TIEMPO DE TRACCION PERTENECIENTE A UN SEMICICLO, MIENTRAS SE AVERIGUA LA SUPERFICIE, LA CUAL ES INCLUIDA EN LA REPRESENTACION EN UN DIAGRAMA DE TIEMPO DE TRACCION DE LA VARIACION PERTENECIENTE A UN SEMICICLO DE LA TRACCION PRIMARIA Y A TRAVES DE LA LINEA CERO DE LA TRACCION PRIMARIA (30).
