Arrangement for connecting a railway power supply for a railway track to a three-phase supply network

摘要

The invention relates to an arrangement (40) for connecting a railway power supply (PF1, PF2, NF1, NF2) for a railway track to a three-phase supply network (L1, L2, L3). The arrangement has a three-phase AC transformer (42-44, 55-62, 64, 65) and a balancing device (41) for a uniform electric load of the three phases of the three-phase supply network (L1, L2, L3). The three-phase AC transformer (42-44, 55-62, 64, 65) is suitable for connecting to the three-phase supply network (L1, L2, L3) on the primary side and is connected to the balancing device (41) on the secondary side. The invention is characterized in that the three-phase AC transformer (42-44, 55-62, 64, 65) is suitable for connecting to a railway power supply which has an autotransformer system with two contact lines (PF1, PF2) and two conductors (NF1, NF2) that are carried along the railway track in an insulated manner.
