Abstract

LA INTERFAZ (SLIC) DEL CIRCUITO DE CONEXION DE ABONADO SE SUBDIVIDE EN UN COMPONENTE DE ALTA TENSION (HV) Y EN UN COMPONENTE DE BAJA TENSION. EL COMPONENTE DE ALTA TENSION ESTA DESCONECTADO EN LOS PERIODOS DE NO OCUPACION. UNA DE LAS DOS TENSIONES DE ALIMENTACION DEL COMPONENTE DE BAJA TENSION SE APLICA A TRAVES DE UN INTERRUPTOR (S,R) PUENTEADO CON UNA RESISTENCIA ALTA. CON ELLO SE PUEDE OBTENER UNA REDUCCION ADICIONAL DE LA POTENCIA PERDIDA EN LOS PERIODOS DE NO OCUPACION SIN QUE SE PRODUZCAN EN LA INTERFAZ (DS) ENTRE EL COMPONENTE DE BAJA TENSION Y EL MANDO CENTRAL (ST) DESPLAZAMIENTOS DE TENSION INADMISIBLES, DEBIDOS A LA IMPOSIBILIDAD DE DESCONECTAR, POR RAZONES DE COSTE, LA SEGUNDA TENSION DE ALIMENTACION.
