With the rapid development of China's high-speed railways, the voltage level of railway traction transformers continues to upgrade. The 220kV electrical grid has a large capacity, and the harmonics and negative-sequence components generated by 220kV single-phase traction transformers have a minimal impact on the 220kV electrical grid. The 220kV power supply system offers greater stability and reliability, and single-phase supply aligns better with the characteristics of railway electrification. It is characterized by simplicity in protection, lower initial investment, and the ability to reduce railway operational costs effectively. As China's economy and power system continue to evolve,220kV single-phase traction supply is an inevitable trend. The connection configuration for single-phase traction transformers is in the I-I form. Depending on capacity or user requirements, internal connections can be either series or parallel.
