Abstract

ESTE CIRCUITO TRANSMITE UNA CORRIENTE DE MEDICION (1), QUE ES ENTREGADA DESDE UN DISPOSITIVO SENSORIAL (1) A UN PUNTO DE MEDICION SITUADO EN UNA ZONA CON SEGURIDAD PROPIA (10), A UNA ZONA SIN SEGURIDAD PROPIA (20) POR MEDIO DE LA RESISTENCIA DE MEDICION DE CORRIENTE (5) SITUADA EN ESTA ZONA. AL MISMO TIEMPO SE ALIMENTA CON ENERGIA EL DISPOSITIVO SENSORIAL DESDE LA ZONA SIN SEGURIDAD PROPIA POR MEDIO DEL CONVERTIDOR DE TENSION CONTINUA (3). ESTE CONTIENE EL TRANSFORMADOR (2), QUE MUESTRA EL BOBINADO PRIMARIO VUELTO HACIA LA ZONA SIN SEGURIDAD PROPIA CON DOS BOBINADOS PARCIALES (21, 22), IGUALES Y CONECTADOS EN SERIE EN EL MISMO SENTIDO, Y UN UNICO BOBINADO SECUNDARIO (23) VUELTO HACIA LA ZONA CON SEGURIDAD PROPIA. LA RESISTENCIA DE MEDICION DE CORRIENTE (5) ESTA SITUADA ENTRE LA CONEXION CENTRAL DE LA ETAPA DE SALIDA (31) DEL CONVERTIDOR DE TENSION CONTINUA (3) Y EL PUNTO CERO DE LA CONEXION (SN). LA CONEXION CENTRAL SE HA CONECTADO A LA ENTRADA DE LA ETAPA DE AJUSTE DE OFFSET (6), CUYA SALIDA ESTA UNIDA A LA ENTRADA DEL CONVERTIDOR DE TENSION A CORRIENTE (7). LA FUENTE DE ENERGIA (4) ESTA SITUADA ENTRE EL PUNTO DE UNION DE LOS BOBINADOS PARCIALES (21, 22) Y EL PUNTO CERO DEL CIRCUITO.
