ABSTRACT:
An apparatus for converting an arc furnace installation from three-phase operation to d.c. operation wherein in order to ensure optimum d.c. operation after converting the three-phase arc furnace installation to d.c. operation, while retaining the three-phase furnace transformer and the high-voltage switchgear, there is connected an adaptation member (2, 7) for adjusting the arc voltage and/or for increasing the inductive reactance, in addition to the actual rectifier arrangement. This adaptation member is formed of a transformer, preferably an autotransformer, and/or a choke circuit.
