Beschreibung
Zusammenfassung:	A metro traction power supply system with a combined dry-type transformer comprises an alternating current switch cabinet, a rectification energy feedback combined transformer, a rectification device and an energy feedback converter. A high-voltage winding, an energy feedback winding, a rectifying winding and an iron core are arranged in the rectifying and energy feedback combined transformer, the energy feedback winding and the rectifying winding share the high-voltage winding and the iron core, the high-voltage winding is connected with an alternating-current switch cabinet, the energy feedback winding is connected with an energy feedback converter, the rectifying winding is connected with a rectifying device, and the rectifying device and the energy feedback converter are connected with a direct-current bus. The AC switch cabinet is connected with the medium-voltage AC bus. According to the metro traction power supply system, the rectifier transformer and the energy feedback transformer are integrated toge
