Abstract
DISPOSITIVO DE PROTECCION DE CORRIENTE DIFERENCIAL, DENOMINADO EN LO SUCESIVO COMO DISPOSITIVO DI, CON UN CIRCUITO TRANSDUCTOR, CUYO CIRCUITO DE VALORACION (11) SE DISPONE ENTRE EL DEVANADO SECUNDARIO (6) Y UNA RESISTENCIA COMPLEJA FUNDAMENTALMENTE CAPACITATIVA (9) DENOMINADA COMO RESISTENCIA DE MEDICION, QUE JUNTO CON EL DEVANADO SECUNDARIO (6) FORMA UN CIRCUITO DE VIBRACION Y QUE ACTUA SOBRE UN SISTEMA DE DISPARO (12) , FUNCIONANDO EL CIRCUITO DE VALORACION (11) CON CIRCUITO RECTIFICADOR, CIRCUITO DE RETARDO E INTERRUPTOR DE VALOR UMBRAL. SE PREVE QUE ENTRE EL INTERRUPTOR DE RECTIFICACION (17) Y EL INTERRUPTOR DE VALOR UMBRAL (19) SE SINTONICE UN PRIMER CIRCUITO DE RETARDO (18) DE MANERA QUE SE CONSIGA UN COMPORTAMIENTO DE DISPARO DESEADO Y QUE EN SERIE CON EL INTERRUPTOR DE VALOR UMBRAL (19) SE CONECTO UN SEGUNDO CIRCUITO DE RETARDO (20) SINCRONIZADO DE MODO QUE LA TENSION EN EL MISMO DISMINUYA MAS LENTAMENTE QUE LA DEL PRIMER CIRCUITO DE RETARDO (18) PARA QUE EN CASO DE DESCONEXION DE LA TENSION DE RED NO SE PRODUZCA NINGUN DISPARO.
