摘要

针对大型油浸式变压器内部流—固耦合的流动传热过程

采用控制体积法（FVM）将流—固—热耦合流动传热的非线性偏微分方程转变为网格单元上积分形式的守恒方程

对积分形式的守恒方程应用高斯散度公式得到控制体边界形式的积分守恒方程

通过应用PISO算法分离求解出绕组与变压器油的温度分布

计算结果与实测数据进行比较

验证了FVM法计算大型油浸式变压器三维流—固—热耦合场的可行性与准确性

并在此基础上应用FVM仿真计算不同风机控制策略下绕组与变压器油的温度分布

对比分析获取最优风机控制策略

对实际运行的大型油浸式变压器风机的智能控制有一定的参考价值。

Abstract

For the flow and heat transfer processes of large-scale oil-immersed transformer’s internal fluid-solid coupling

the nonlinear partial differential equations of flow-solid-thermal coupling flow and heat transfer can be transferred based on FVM method into conservation equations of integral form on the grid unit

which applies the Gauss divergence formula to get the integral conservation equation of control body in the form of borders. Finally

the temperature distribution of core

winding and transformer oil by applying PISO algorithm

verified the reliability and accuracy of FVM method is verified by comparison of the calculated results with the measured data. Also

the temperature distribution of transformer winding and oil is gotten by the application of FVM simulation. The optimal control strategy of fan is realized by comparative analysis. This has a certain significance reference for the intelligent control of large oil-immersed power transformer’s fan.
