Abstract

Simulation results of thermal characteristics of dry-type and oil-filled power transformer TM-160/10 in no-load and short-circuit modes are presented. Electrical, geometrical and thermal characteristics of TM-160/10 transformer have been determined. Computer modeling was performed in ANSYS17.1 software package. 2D distributions of temperature and heat flux density in transformer in longitudinal and transverse sections were determined. It is shown that the use of transformer oil for transformer cooling significantly reduces temperatures in the active part. The temperature distribution occupies the range of 67-91 °С. Accordingly, the temperature of the most heated part is 91 °С and also corresponds to the low voltage winding. The dependence of the most heated point of the transformer on the operating mode has been studied. A formula for calculation of maximum transformer temperature depending on power loss has been proposed.
