摘要
基于计算流体力学(CFD)模拟技术,利用流体仿真分析软件Icepak对户内变电站的通风过程进行了仿真模拟计算,分析了不同进风口和出风口位置对变压器温度场分布和气流组织情况的影响,得到了最佳的通风换热方案。结果表明:在散热器正下方布置进风口可以改善气流组织状况并提高散热器换热效率,显著降低片式散热器温度并获得比较均匀的温度场。
Based on computational fluid dynamics(CFD) simulation technology, this paper uses Icepak, the fluid simulation analysis software, to simulate and calculate the ventilation process of indoor substation. The effects of different air inlets and outlets on the transformer temperature field distribution and airflow organization of the indoor substation are analyzed, and the optimal ventilation heat exchange scheme is obtained. The results show that the air inlet located directly under the radiator can improve the airflow organization and the heat exchange efficiency of the radiator, significantly reduce the temperature of the transformer and obtain a relatively uniform temperature field.
