Abstract

To study the temperature rise of dry-type transformer in different cooling conditions, finite element method is used in this paper to calculate temperature distribution in the transformer. Firstly, thermal-fluid coupled model of a transfomer is built up，and the equivalent heat generation of this model is figured out according to the results of delivery test. Then, thermal-fluid coupled model is simulated in both natural cooling condition and forced cooling condition, and temperature distributions in the iron and windings under these two conditions are obtained. Finally, temperature rises in these two conditions are compared to figure out the influence of cooling condition on transformer temperature rise.
