The invention relates to a 10kV/27.5 kV electrified railway auxiliary traction power supply. The 10kV/27.5 kV electrified railway auxiliary traction power supply comprises a box body with an accommodating space, an incoming line unit, a transformer and a feeder line unit, wherein the incoming line unit, the transformer and the feeder line unit are arranged in the box body, wherein one end of the incoming line unit is electrically connected with a public power grid power supply line, the other end of the incoming line unit is electrically connected with the input end of the transformer, the transformer is used for boosting a 10kV voltage to a 27.5 kV voltage, the output end of the transformer is electrically connected with one end of the feeder line unit, and the other end of the feeder line unit is electrically connected with an electric locomotive power supply line; the public power grid power supply line is used for transmitting the 10kV voltage, and the electric locomotive power supply line is used for transmitting the 27.5 kV voltage. The embodiment of the invention can meet the power supply requirement of the existing electric locomotive beyond the capacity range of the traction substation, and is easy to implement, small in occupied area and relatively high in cost performance.
