| Abstract: | For a winding model of cable winding transformer, the finite element equations of temperature field and flow field were built according to thermodynamics and hydrodynamics principles. After calculating the equations, the comparison between the calculated results and measured ones shows the agreement: the difference was less than 3K. It was verified that the temperature distribution and flow distribution could be solved by this method. For this new type of transformer, it can bring some conveniences for the research of temperature characteristics. |
