Abstract

The disclosure provides a traction transformer and a power supply circuit for a locomotive. The traction transformer includes a magnetic core; a ground power supply winding surrounds the magnetic core and is used to connect to a ground power supply network; system; a high voltage winding, surrounding said traction winding, for connection to the grid. The traction transformer of the present disclosure integrates the ground power supply winding into the traction transformer to realize the locomotive moving under the condition of temporary power supply, without modifying the auxiliary circuit of the locomotive or rearranging equipment, and without adding additional transformers, which simplifies the structure of the temporary moving train circuit and saves manufacturing cost.

Description

technical field [0001] The present disclosure relates to the technical field of driving electric locomotives, and in particular, relates to a traction transformer that can be applied under temporary power supply conditions and a locomotive power supply circuit using the traction transformer. Background technique [0002] Electric locomotives are generally powered by the catenary in the manufacturing plant and maintenance base, but under certain working conditions, if the locomotive is to go to the designated station for test / overhaul, in order to ensure work safety, the high-voltage catenary in the locomotive test / overhaul work area The power should be cut off, or there is no catenary in this area. At this time, since the catenary cannot supply power to the locomotive, it is necessary to use other methods to move the train. [0003] In the related technology, the motor car power socket in the depot is set under the electric locomotive. In the area where the catenary cannot s...
