摘　　要：采用有限元法对容量800 kVA的10 kV干式变压器建立三维对称仿真模型,仿真计算了变压器的温度场和空气流体场的分布,并分析了不同结构参数下散热板对变压器温升的影响,为干式变压器的散热优化提供支持。This paper establishes a three-dimensional symmetric simulation model of an 800 kVA 10 kV dry-type transformer using finite element method,through which a simulative calculation onthe temperature field and air fluid field distribution of the transformer is performed.It also analyzes the influence of heat dissipation plates with different structural parameters on temperature rise of the transformer,providing support for thermal optimization of dry-type transformers.
