Details

The reverse Scott transformer is a special type of transformer that can convert the two-phase electricity (two single-phase with a phase difference of 90 °) of the power supply (referred to as the road network) into three-phase electricity, that is, the traction equipment side (referred to as the station side). The reverse Scott transformer consists of two single-phase transformers, and the end of the low-voltage winding (i.e. the secondary winding) of one transformer is connected to the center of the secondary winding of the other transformer to form a T-shaped three-phase secondary winding. The two single-phase transformers connected in this way can be used as two-phase three-phase transformers, with the former referred to as T transformer and the latter referred to as M transformer. The primary voltage of the transformer is two 27.5kV single-phase voltages, and the secondary voltage is 400V three-phase voltage.

The reverse Scott transformer is suitable for electrified railway traction substations, switching stations, AT stations, and section stations, converting the 27.5kV voltage of the traction transformer on the railway network side into 400V or 230V voltage. Provide internal lighting, control and protection, fans, operating mechanisms and other power sources for the traction substation.
