Title (EN) POWER SUPPLY AND CONTROL DEVICE FOR THE PROPER OPERATION OF A RAILWAY TRAFFIC LIGHT
(FR) DISPOSITIF D"ALIMENTATION ET DE CONTROLE DU BON FONCTIONNEMENT D"UN FEU DE SIGNALISATION FERROVIAIRE
Abstract: front page image
(EN)Such device comprises a periodic current generator (6) connected to a long power supply line (3) through a first transformer (7), the lamp (1) of the light being connected to the long line through a second transformer (9). A first and a second safety capacitors (11 and 13) with four terminals are respectively arranged in series on the long line (3) with the corresponding transformer (7 and 9), so as to ensure the circulation of a DC current generated by a detector (2) of good working operation towards the coil of a relay (4) sending back the information to a central control station (5). Application to railway traffic signalling.
(FR)Dispositif incluant un generateur de courant periodique (6) relie a une ligne longue (3) d"alimentation par l"intermediaire d"un premier transformateur (7), la lampe (1) du feu etant relie a la ligne longue par l"intermediaire d"un second transformateur (9). Un premier et un second condensateurs (11 et 13) de securite a quatre bornes sont respectivement disposes en serie dans la ligne longue (3) avec le transformateur correspondant (7 et 9), de maniere a assurer la circulation d"un courant continu engendre par un detecteur (2) de bon fonctionnement vers l"enroulement d"un relais (4) renvoyant l"information vers un poste de commande central (5).
