Abstract:
1. A device for connecting a single-phase supply line to a three-phase power supply system, comprising: a single three-phase transformer having a primary side connected to the three-phase power supply system and a secondary side, said secondary side having a first phase, a second phase, and a third phase; a three-phase intermediate-circuit converter forming a balancing device connected between said transformer and the single-phase supply line; said secondary side of said transformer having a first phase connected to the single-phase supply line, a second phase connected to said balancing device, and a third phase connected to a ground connection; wherein the single-phase supply line is a sole single-phase supply line; and said balancing device having a first phase connected to said second phase of said transformer, a second phase connected to the single-phase supply line, and a third phase connected to the ground connection.
