Multi-current traction transformer and railway vehicle

The invention discloses a multi-current traction transformer which comprises an iron core. The iron core is provided with two iron core columns, two additional windings are arranged on the outer sideof each iron core column, a traction winding is arranged on the outer side of each additional winding, and a high-voltage winding is arranged on the outer side of each traction winding. Obviously, inthe multi-current traction transformer, since the traction winding is arranged on the outer side of the additional winding, and the high-voltage winding is arranged on the outer side of the traction winding, only the electrical distance between the high-voltage winding and the traction winding needs to be considered emphatically. The traction winding and the additional winding are not required tobe wound, and the electrical distance between the traction winding and the additional winding is not required to be specially considered, so that the structural compactness of the multi-current traction transformer can be remar
