电力变压器铁芯温度场分布的数值模拟及分析

Numerical Calculation and Analysis of Temperature Field Distribution of Core in Dry Type Power Transformer

应用ANSYS有限元软件的顺序耦合法,分析了变压器的电磁场分布,并将电磁场分析结果作为热生成率载荷,得到干式电力变压器铁芯的内部温度场分布.该方法可有效减少变压器的设计成本,也可以对已运行的设备进行电磁场和热场分布的分析.

By using the coupling method of ANSYS finite element software,the electromagnetic field distribution of the transformer is analyzed.Then using the electromagnetic field analysis results as the load heat generation rate,the power transformer iron core internal temperature distribution is obtained.This method can effectively reduce the cost of the transformer design and thus can be used in the analysis of electromagnetic and thermal field distribution.
