| Abstract: | With a focus on the 750 kV combined transformer, this paper introduces the background of application of the 750 kV single phase three winding catamaran combined transformer, and elaborates the equipment design, layout design, control and protection design of the transformer. Comparision are mainly made between the conventional transformer and the combined transformer in terms of the equipment size, transportation size no-load loss and load loss as well as the layout of the substation. Finally, based on the actual development of power grids in the northwest region of China, it puts forward some prospects on the future application of the 750 kV combined transformer. |
