Abstract
UN MODULO PARA INSERCION DENTRO DE UNA LINEA DE TRANSPORTE COMBINADO DE SEÑAL Y ENERGIA, ESPECIALMENTE DENTRO DE UNA LINEA CATV, PARA PROTEGER UN SISTEMA ASOCIADO CON LA LINEA DE UNA SOBRE CORRIENTE COMPRENDE: (I) UN ALOJAMIENTO (50) QUE TIENE PUERTOS (51, 52) DE CONEXION PARA CABLES (53, 54) QUE FORMAN LA LINEA Y ESTANDO ADAPTADO EN IMPEDANCIA A LA LINEA, ESTANDO UNO DE LOS CONDUCTORES DE LOS CABLES CONECTADOS JUNTOS A TRAVES DE UN CONDENSADOR (23); Y (II) UN CIRCUITO DE PROTECCION DE SOBRE CORRIENTE DE ESTADO SOLIDO QUE ESTA CONECTADO A TRAVES DEL CONDENSADOR MEDIANTE INDUCTANCIAS (24,25) PARA AISLARLE DE LA SEÑAL SOBRE LA LINEA, SIENDO EL CIRCUITO DE PROTECCION CAPAZ DE CONMUTAR DESDE UN ESTADO DE CONDUCCION A UNO DE BLOQUEO EN RESPUESTA A UNA SOBRE CORRIENTE Y SIENDO CAPAZ DE RESTAURARSE POR SI MISMO O INTENTAR VOLVER POR SI MISMO A SU ESTADO DE CONDUCCION UNA O MAS VECES DESPUES DE QUE HAYA SIDO CONMUTADO A SU ESTADO DE BLOQUEO. SI UNA LINEA QUE CONTIENE UN NUMERO DE TALES MODULOS ES SOMETIDA A UNA SOBRE CORRIENTE, EL DISPOSITIVO DE PROTECCION EN EL MODULO MAS PROXIMO CORRIENTE ARRIBA SERA CONMUTADO DE MODO QUE SOLO PARTE DE LA LINEA CORRIENTE ABAJO DEL MODULO SERA AFECTADA. ADICIONALMENTE, EL SEGUIMIENTO DE LA LOCALIZACION DEL FALLO ES MUCHO MAS SIMPLE PORQUE LA SECCION DE LA LINEA EN LA CUAL OCURRE EL FALLO ES CONOCIDA DESDE EL CIRCUITO DE PROTECCION QUE SE HA DISPARADO.
