摘要:

以天津某地铁站变电所变压器室为研究对象,通过送回风口位置的变化,设计出4种不同气流组织方式,利用CFD技术模拟房间内部空间气流分布情况,讨论气流组织方式对变压器室换热效果的影响。通过对速度场及温度场的分析,提出变压器室气流组织设计中应注意的问题,推荐较好的气流组织方式,对工程设计具有一定的指导意义。

Abstract:

A transformer plant of a substation of a Metro station in Tianjin is studied in this paper. Four different air distribution modes are designed by changing the positions of the air inlet and outlet ports. The air distribution in the transformer plant is simulated by CFD technology. The influence of the air distribution modes on the heat transfer in the transformer plant is discussed. Key points to which attention should be paid in the design of the air distribution in the transformer plant are listed on basis of analysis on the flow field and temperature field and proper air distribution modes are recommended. The paper can be served as guidance for similar projects in the future.

Key words: Metro station, substation, transformer plant, air distribution, CFD
