Both of the traction transformers in the Shanghai-Nanjing intercity railway and Beijing-Shanghai high-speed railway connect two single-phase traction transformers as V/X wiring to form a complete traction transformer. One is operating, and the other one stand-by for it. First, the thesis analyzes the low-voltage side short current of V/V wiring traction transformer, and then calculates the measuring...
This paper describes that the use of large capacity110kV transformers in Jiangsu power grid makes the mismatch between the capacity of 220kV transformer and the capacity of 110kV transformer. As the capacity of 110kV transformer is too large, its short-circuit impedance is relative small, while the capacity of 220kV transformer capacity is relative small, the conventional configuration and setting...
