The commonly used connection methods for 110kV railway traction transformers include single-phase traction transformers and V/V connection traction transformers. Single-phase traction transformers are characterized by low-temperature rise, low losses, low noise, strong overload capacity, strong short-circuit resistance, and a suspended core-free structure. On the other hand, V/V connection traction transformers offer advantages such as high capacity utilization, simple structure, flexible capacity configuration, and ease of transportation.
