Thermal analysis using 3D FEM model of oil-immersed distribution transformer

摘要

The temperature distribution in the transformer interior is a significant parameter governing a transformer's performance and life expectancy. In the perspective of the user, temperatures in a transformer are important to determine the amount and duration of over load it can sustain, and to estimate the effects on the life of the transformer by operation at various temperatures. This paper presents the temperature field distribution modeling of oil-immersed distribution transformer 160kVA. Finite element method and ANSYS program have been employed for 3D model development. Based on this model, the thermal field distribution with values of temperature has been obtained.
