MODERNIZATION OF FRENCH NATIONAL RAILWAYS 1,500 V DIRECT CURRENT SUB-STATIONS

LA MODERNISATION DES SOUS-STATIONS A COURANT CONTINU 1 500 V DE LA S.N.C.F

Most of the sub-stations were equipped with mercury vapor rectifiers, or even rotary converters. 90% of the traction current supply installations have silicon rectifiers. New sub-stations have been built on inadequately equipped lines. At the same time remote control centers have been improved and operate over a wider area; some new centers have been built. The author explains how the technological development of rectifiers has, in older sub-stations, enabled equipment capable of coping with the higher power required to be installed, which at the same time produced a very appreciable reduction in operating and maintenance costs. He explains in this connection the policy adopted as far as voltage control and current recuperation are concerned. The article refers to the measures taken to protect the 1,500 V sectors.
