Abstract

In this investigation using (PCMs), the phase change materials in the electrical transformer is numerically analyzed by CFD. In this paper used oil transformer and PCMs (Wax, RT44 and P116), the cooling as mediums which are represented the heat storage assistance the oil. Ten kilogram of PCMs used as shield around the windings and coils. A (25, 37, 45 and 55 Co) represented surrounding temperatures that are taken. Because of, absorbed the heat by the latent heat that got it from PCM, the PCM added at transformer temperature shows clear decreasing the average temperature. The boundary condition represented with mixed (convection and radiation), heat generation applied on the transformer. The results displayed that, temperature reduction of the transformers is about 4 Co due to use of different types of PCM.
