초록
In this paper, temperature distribution of 24 MVA distribution cast-resin transformers is analyzed by using CFD. Usually heat generated in transformer causes many problems. To radiate the heat, conduction and convection are done through the duct between winding. Considering natural convection, fluid analysis is applied to the fluid region surrounding the transformer. As a result of the analysis, hot spot temperature point is predicted at the low-voltage winding. Through this paper, heat distribution and cooling characteristics property can be predicted by analyzing transformer heating characteristic required when designing.
