Shell-type integrated multi-winding transformer for electric locomotive

The utility model discloses an electric-locomotive casing style integrated multiple-winding transformer, relating to an electric power transformer used for an electric-locomotive. The utility model adopts an iron core with a rectangle section, and high voltage windings and low voltage windings are sequentially positioned in an iron core window. The iron core resembles an outer casing encircling the windings, and the casing style structure can protect coils better. And the height of the utility model is so low that a plurality of oil-sharing systems of reactors and transformers can be conveniently arranged, and then an oil tank with a proper form can be formed, and an iron core clamping part can be displaced to simplify the oil tank. The volume of the transformer is reduced and the weight becomes lighter and the oil of transformer is decreased. A core style transformer adopts less iron than a casing style transformer while uses more copper, with higher manufacturing cost. The technical index and economic index of the casing style transformer is more advanced, and the energy cost is low and the over loading capability is strong, and the structure is compact and the running is reliable.
