Abstract

CONTACTO ELECTRONICO Y DISPOSITIVOS ASOCIADOS COMO MEDIOS DE LIMITACION DE POTENCIA. CONSTAN DE UN DISPOSITIVO DE PROTECCION DE TENSION PARA PONER EL CONTACTO EN ESTADO PREDETERMINADO CUANDO LA TENSION A TRAVES DE ESTE EXCEDE UN DETERMINADO VALOR (VD); Y DE UN DISPOSITIVO DE PROTECCION DE CORRIENTE PARA COLOCAR EL CONTACTO ELECTRONICO (TRX) EN DICHO ESTADO PREDETERMINADO, CUANDO LA CORRIENTE QUE FLUYE A SU TRAVES EXCEDE DE UN VALOR PREDETERMINADO. LOS DISPOSITIVOS DE PROTECCION DE CORRIENTE Y TENSION ESTAN ACOPLADOS EN SERIE Y PARALELO CON EL CONTACTO ELECTRONICO (TRX), RESPECTIVAMENTE, Y TIENEN UNA SALIDA COMUN ACOPLADA A UN TERMINAL DE CONTROL DE DICHO CONTACTO ELECTRONICO. DE APLICACION EN CENTRALES DE TELECOMUNICACION.
