Abstract

EL APARATO DE ACCESO DE LINEA PARA COMUNICACION DENTRO DE LA BANDA INCLUYE UN ACOPLADOR DE LINEA QUE FUNCIONA COMO DISPOSITIVO DE AISLAMIENTO DE ALTO VOLTAJE Y TIENE UNA FRECUENCIA RESONANTE DE LA BANDA DE TRANSMISION DE SEÑAL. UNA SEÑAL PORTADORA DE, APROXIMADAMENTE, LA FRECUENCIA RESONANTE, SE MODULA EN UNA FRECUENCIA DENTRO DE LA BANDA PARA TRANSPORTAR INFORMACION POR EL ACOPLADOR DE LINEA. EL APARATO LLEVA UN ENCHUFE (18) ADAPTADO PARA SU INSERCION ENTRE EL CUADRO DISTRIBUIDOR Y VARIOS BLOQUES PROTECTORES DE ALTO VOLTAJE. EL ENCHUFE LLEVA VARIAS CLAVIJAS (20), CADA PAR DE LAS CUALES PUENTEA UN PAR DE LINEA CORRESPONDIENTE. ASOCIADAS CON LAS CLAVIJAS (20) HAY DISPOSITIVOS PIEZOELECTRICOS (24) QUE ACTUAN TANTO COMO AISLADORES DE VOLTAJE COMO ACOPLADORES DE SEÑAL.
