The invention provides a traction transformer for a cophase power system. The traction transformer is characterized by comprising a primary transformer and a teaser transformer which are arranged in the same oil tank and connected in an inequilateral Scott connection way. According to the combined type cophase supply supply scheme disclosed by the invention, the primary matching transformer can be cancelled, so that the floor space is reduced, the cost is saved, the system efficiency is improved. The traction transformer is a novel two-side feeding important part of a railway traction power supply system, so that sectional type power supply, measuring, governance negative sequence and phase slit at an transformer outlet are achieved, and the optical reactive compensation is realized.
