Summary:A traction transformer connection mode for railway at 110kV level voltage with one change and two uses belongs to transformer production field. (1) High voltage and low voltage windings of transformer both has two parts. (2) When the A and C ends of high voltage winding connects with 110kV circuitry as input ends, a and c ends of low voltage winding output full capability and low voltage 27.5kV as the traction transformer connection mode for railway. (3) When the A and C ends or N and M ends of high voltage winding connects with 110kV circuitry as input ends, the m and n ends or a and c ends of low voltage winding output low voltage 10.5kV as the traction transformer connection mode for railway station. It effectively enhances the utilization ratio of transformer content with low cost and saves cost of equipment and small area to enhance system dependability.
