MODERN THYRISTOR TECHNOLOGY REPLACES MERCURY ARC CONVERTERS ON AC OPEN-WORK MINING LOCOMOTIVES WITH REGENERATIVE BRAKING AT THE WEST GERMAN LIGNITE WORKS: RHEINISCHE BRAUNKOHLENWEREK AG (RBW)

MODERNE THYRISTORTECHNIK ERSETZT QUECKSILBERTDAMPF-STROMRICHTER AUF WECHSELSTRON-TAGEBAULOKOMOTIVEN MIT NETZBREMSE BEI DEN RHEINISCHEN BRAUNKOHLENWERKEN AG (RBW)

In 1974 RBW placed an order to convert eleven converter locomotives (6 kv 50 Hz) for heavy overburden and coal haulage to modern power electronics and control. The mercury arc converters will be replaced by modern thyristors with high reverse voltage rating in bridge connection. A prototype of this conversion, which forms part of a long-term modernizing program of the RBW, was the locomotive No. 500 which has been in service since 1965. This locomotive had been equipped with thyristor phase-angle control not only for driving operation but also for regenerative braking with feedback of energy. A description is given of the circuit arrangement of the power circuit and of the regulating and control devices by means of diagrams, charts and block diagrams.
