电力变压器铁芯温度场的数值解法与实施

A New Approach to Calculating 3D Temperature Field in Transformer Cores

本文系统地介绍了求解电力变压器铁芯温度场的三维数值方法,较好地解决了流体—构件耦合场的数值求解问题,并采用有限元法对若干影响铁芯温升的相关因素进行了大量的数值模拟研究。

The temperture field in a large transformer core is a typical fluid-structure interaction coupled field between oil and cores, but in previous literatures the computation of the field was in general decoupled. For solving that field, the analysis models, numerical methods as well as some useful results are reported in this paper.
