POWER SUPPLY OF DC TRACTION SYSTEMS

DIE TECHNIK DER ENERGIEVERSORGUNG VON GLEICHSTROMBAHNEN

In d.c. traction systems power is fed to the contact system through a large number of substations arranged alongside the track. This is necessary because of the greatly varying demand for power in traction service. The substations employ medium-voltage metal-clad switchgear and self-ventilated silicon rectifiers. High-speed d.c. breakers with rate-of-change current relays provide selective protection of the sections. Automatic reclosing restores the power supply quickly on faults. New load-break switches provide for coupling and tripping of individual feeder sections outside the substation. Electronic suppervisory remote control permits operation and monitoring from a central point.
