Abstract

The invention provides a traction transformer and a locomotive power supply circuit. The traction transformer comprises a magnetic core; a ground power supply winding which surrounds the magnetic coreand is used for being connected with a ground power supply network; a traction winding which surrounds the ground power supply winding and is used for being connected with a locomotive traction system; and a high-voltage winding which surrounds the traction winding and is used for being connected with a power grid. According to the traction transformer disclosed by the invention, the ground powersupply winding is integrated in the traction transformer, so the locomotive is driven under a temporary power supply condition, a locomotive auxiliary circuit does not need to be modified or equipment does not need to be rearranged, an additional transformer does not need to be added, the temporary motor train circuit structure is simplified, and the manufacturing cost is saved.

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...
