ARRANGEMENT FOR CONNECTING A RAILWAY POWER SUPPLY FOR A RAILWAY TRACK TO A THREE-PHASE SUPPLY NETWORK

摘要

An arrangement for connecting a railway power supply for a railway track to a three-phase supply network. The arrangement has a three-phase AC transformer and a balancing device for a uniform electric load of the three phases of the three-phase supply network. The three-phase AC transformer is configured for connecting to the three-phase supply network on the primary side and is connected to the balancing device on the secondary side. The three-phase AC transformer is configured for connecting to a railway power supply which has an autotransformer system with two contact lines and two conductors that are carried along the railway track in an insulated manner.
