Abstract
L'INVENTION CONCERNE UN DISPOSITIF D'ALIMENTATION EN COURANT CONTINU D'UNE LIGNE DE POSTE TELEPHONIQUE. LA LIGNE TELEPHONIQUE EST ISOLEE DU CENTRAL DU POINT DE VUE DES COURANTS CONTINUS PAR DES CONDENSATEURS (20A, 20B). DEUX GENERATEURS DE COURANT CONSTANT SYMETRIQUES (8A, 8B) ALIMENTENT, A PARTIR D'UNE SOURCE 3 LES DEUX CONDUCTEURS DE LA LIGNE TELEPHONIQUE. LA REGULATION ET L'EQUILIBRAGE DES COURANTS DES GENERATEURS EST ASSUREE PAR UN PONT DE RESISTANCES (9A, 9B) CONNECTEES ENTRE LES CONDUCTEURS DE LA LIGNE ET DONT LE POINT MILIEU EST RELIE AUX ENTREES DE COMMANDE DES GENERATEURS. APPLICATION AUX CENTRAUX TELEPHONIQUES ELECTRONIQUES OU ELECTROMECANIQUES.
