Abstract

LAS PIEZAS DE CONEXION DE RED MODERNAS CONSTAN DE UNA PIEZA DE MINERAL INTEGRADO (IS) QUE ASUME LA DIRECCION DE LA CONEXION (7). ESTE PIEZA DE MINERAL ES FRECUENTEMENTE CONECTADA A UNA RESISTENCIA RESIDUAL (14) EN ESTADO DE INACTIVIDAD Y A TODOS LOS PUNTOS DE CONEXION EN ESTADO DE ACTIVIDAD. EN ESTADO DE ACTIVIDAD ES ALIMENTADA POR UNA BOBINA DE TRANSFORMADOR (15) CON LA TENSION PRECISA. SI SE LE ENVIA A LA PIEZA MINERAL UN COMANDO DE DESCONEXION, EL CONECTOR NO ES PUESTO EN FUNCIONAMIENTO. ESTO TIENE COMO CONSECUENCIA QUE LA PIEZA MINERAL MANTENGA UN PERIODO DE FUNCIONAMIENTO PROVISIONAL EN EL QUE OSCILA ENTRE LA ACTIVIDAD Y LA INACTIVIDAD. LA DURACION DE ESTE PERIODO ES DETERMINADO POR EL CONDENSADOR DE TRANSMISION. PARA PONER EN FUNCIONAMIENTO LA PIEZA MINERAL , DESPUES DE FINALIZADO EL PERIODO DE DESCONEXION, SE PROPONE BLOQUEAR EL ESTADO DE ACTIVIDAD MEDIANTE UN COMANDO DE DESCONEXION. ACTO SEGUIDO EL CONDENSANDOR (13), DESPUES DE EMITIDO EL COMANDO DE DESCONEXION DARA LUGAR A LA TENSION NECESARIA PARA LA ALIMENTACION Y ACTIVACION DE LA TOTALIDAD DEL DISPOSITIVO
