Abstract

DESCONECTADOR ELECTRONICO QUE INCLUYE, PARA CADA LINEA DE FASE O NEUTRO, UN PUENTE RECTIFICADOR FORMADO POR CUATRO DIODOS QUE RECTIFICAN LA CORRIENTE DEL TRANSFORMADOR, UNA RESISTENCIA PARA LA MEDIDA DE LA CORRIENTE RECTIFICADA, Y UN CIRCUITO DE DETECCION DEL SIGNO O DE LA POLARIDAD DE LA CORRIENTE MEDIDA CONECTADA A UN EXTREMO DEL TRANSFORMADOR. UN CIRCUITO DE TRATAMIENTO 9 CALCULA UN VALOR REPRESENTATIVO DE LA CORRIENTE DE DEFECTO A TIERRA SUMANDO TODOS LOS VALORES DE CORRIENTE CUYO SIGNO CORRESPONDIENTE ES POSITIVO Y RESTANDO TODOS LOS VALORES DE CORRIENTE CUYO SIGNO CORRESPONDIENTE ES NEGATIVO. ESTE VALOR DE CORRIENTE ES TRATADO DE MANERA QUE PRODUZCA UNA DESCONEXION CUANDO UN UMBRAL ES SUPERADO DURANTE UN TIEMPO PREDETERMINADO.
