The invention provides a hybrid power distribution device and method and an electrified railway traction power supply system. The hybrid power distribution device is applied to an electrified railway traction power supply system, the electrified railway traction power supply system comprises a traction transformer, an isolation transformer and a converter, the primary side of the traction transformer is connected to a three-phase power system power supply network of an electrified railway, and the secondary side of the traction transformer is connected to the primary side of the isolation transformer; the alternating current side of the converter device is connected to the secondary side of the isolation transformer; the hybrid power distribution device comprises a first power distribution branch used for taking power from a power distribution cabinet in a traction substation control room and providing control power distribution for a converter device; and the second power distribution branch is used for taking power from the secondary side of the isolation transformer, performing voltage regulation and then providing control power distribution for the converter device. According to the invention, control power distribution can be provided for a large-capacity converter device under the condition that the power distribution capacity of a traction substation is not additionally expanded.

    本发明提供一种混合配电装置、方法及电气化铁路牵引供电系统。混合配电装置应用于电气化铁路牵引供电系统,电气化铁路牵引供电系统包括牵引变压器、隔离变压器和变流装置,牵引变压器的原边接入电气化铁路的三相电力系统供电网,牵引变压器的副边接入隔离变压器的原边,变流装置的交流侧接入隔离变压器的副边;混合配电装置包括:第一配电支路,用于从牵引变电所控制室内的配电柜处取电,向变流装置提供控制配电;第二配电支路,用于从隔离变压器的副边处取电并进行电压调节后,向变流装置提供控制配电。本发明可以在牵引变电所不额外扩充配电容量的情况下,实现对大容量的变流装置提供控制配电。
