摘要：
Non-flammable characteristic of dry-type cast- resin transformers make them suitable for residential and hospital usages. However, because of resin's property, thermal behavior of these transformers is undesirable, so it is important to analyze their thermal behavior. Temperature distribution of cast-resin transformers is mathematically modeled in this paper. The solution of the model was carried out successfully by finite difference method. In order to validate the model, the simulation results were compared with the experimental data measured from an 800 kVA transformer. Finally, the influences of some construction parameters and environmental conditions on temperature distribution of cast-resin transformers were discussed.
