Abstract

EL DISPOSITIVO DE PROTECCION LLEVA UN DETECTOR (5) DE CORRIENTE DE DEFECTO DIFERENCIAL CONECTADO A UN PUENTE RECTIFICADOR (D1, D2, D3, D4). LA SALIDA DEL PUENTE ALIMENTA UN CIRCUITO RC (12 13) QUE PROPORCIONA ENTRE DOS LINEAS DE ALIMENTACION (V+, V-), UNA TENSION CONTINUA REPRESENTATIVA DE LA CORRIENTE DE DEFECTO DIFERENCIAL. UN CIRCUITO (24) DE COMPARACION COMPARA CON UN UMBRAL DETERMINADO LA TENSION ENTRE LAS LINEAS DE ALIMENTACION (V+, V-) Y CONTROLA EL ACCIONAMIENTO DE UN RELE (8) DE DISPARO CUANDO LA TENSION SOBREPASA UN UMBRAL PREDETERMINADO. LA TENSION ENTRE LAS LINEAS DE ALIMENTACION, REPRESENTATIVA DE LA CORRIENTE DE DEFECTO, PUEDE APLICARSE A MODULOS AUXILIARES A TRAVES DE LAS RESISTENCIAS (34, 35) CONECTADAS A SALIDAS (32, 33).
