APPLICATION OF THYRISTOR CONTROL TO RAIL TRACTION. IMPACT UPON THE SIGNALLING EQUIPMENT: DISTURBANCES NOTICES AND STEPS TAKEN TO REMEDY THEM

UTILISATION DE LA COMMANDE PAR THYRISTORS EN TRACTION FERROVIAIRE. REPERCUSSIONS SUR LES INSTALLATIONS DE SIGNALISATION: PERTURBATIONS CONSTATEES ET DISPOSITIONS ADOPTEES POUR Y REMEDIER

After recalling that the use of thyristors ensures simultaneous rectification of the traction current and voltage regulation accompanied, however, by the appearance of harmonics, the article introduces the notion of the "equivalent disturbing current" and sums up the results of tests carried out with single phase and dc driving motors. The effect of thyristor control on the signaling system is considered. Different track circuits used by the S.N.C.F. and the terms of coexistence of the latter with thyristorized machines with the appropriate possibilities of disturbance are studied. The experimental results obtained are presented and concrete solutions which have been adopted are described. Also, radio disturbances are discussed.
