Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to an auxiliary transformer for an electric locomotive and an assembly process thereof. Background technique [0002] The electric locomotive itself does not have a prime mover. It relies on receiving the current sent by the catenary as energy, and the traction motor drives the wheels of the locomotive. It has the advantages of high power, high thermal efficiency, fast speed, strong overload capacity, reliable operation, and does not pollute the environment. The traction transformers of the main circuit system of electric locomotives are basically localized, have formed national standards, and have completed product series. In the past, the auxiliary circuit has been powered without transformer conversion, and the traditional single-phase-three-phase power supply system is adopted. The power supply is provided by the auxiliary winding of the traction transformer, an...
