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 together and shared in a time-sharing mode, function integration of the rectifier transformer and the energy feedback transformer is achieved, only one magnetic circuit is arranged, and compared with two transformers, the occupied area of the transformers in a traction power supply room is reduced through one combined transformer, and the cost is reduced. And the manufacturing, transportation, installation, operation and maintenance cost of the transformer is reduced, and the investment of transformer equipment can be saved.

    一种带有组合干式变压器的地铁牵引供电系统,包括交流开关柜、整流能馈组合变压器、整流装置和能馈变流装置。整流能馈组合变压器内设置有高压绕组、能馈绕组、整流绕组和铁芯,能馈绕组和整流绕组共用高压绕组和铁芯,高压绕组连接交流开关柜,能馈绕组连接能馈变流装置,整流绕组连接整流装置,整流装置和能馈变流装置连接直流母线,交流开关柜连接中压交流母线。本发明的地铁牵引供电系统将整流变压器和能馈变压器整合在一起,分时共用,实现整流变压器、能馈变压器功能一体化,且仅设置1个磁路,1台组合变压器相比于2台变压器而言,减小牵引供电室变压器占地面积,减少了变压器的制造、运输、安装、运维成本,可节省变压器设备投资。
