| Abstract: | This paper presents the analysis and calculation of the thermal field of the dry power transformer using FEM. A mathematical and physical model is established, with core, coil and isolator in mind. The anisotropy of the core to transmit heat is considered in the analysis and caf culation. Through the analysis of the calculating results, the inner temperature distribution in the power transformer and the position of hot point are discussed. The effect of the material thermal coefficient is discussed, too. The paper discusses how to check the result of calculations using modern testing technique. |
