摘要
针对智能变电站预制舱式二次组合设备舱,结合框架式二次设备机架方案,研究预制舱式二次组合设备的特点。对舱体结构、运行环境控制和舱体内部设计进行优化,对机架结构与舱体结构进行一体化融合设计,并对舱内高效散热通风方案及舱内工作环境进行优化设计。介绍了机架与舱体整体设计方案以及机架散热通风方案。以郧县220 k V变电站工程项目为例,介绍其二次组合设备舱体环境优化设计方案。对优化后的预制舱进行高温散热仿真计算分析,验证了其良好的散热通风性。
Aiming at secondary combination device cabin of prefabricated cabin in smart substation, and combining rack-mounted secondary device project, this paper researches characteristics of secondary combination device of prefabricated cabin. The cabin structure, operating environment control, internal space of the cabin are optimized. Design of rack construction and cabin structure are integrated. Design of efficient heat dissipation and work environment in cabin is optimized. Design of efficient heat dissipation and ventilate in cabin is optimized. Through a case study of 220 kV Substation in Yunxian County, an optimized design scheme of secondary combination device cabin environment is introduced. High temperature heat simulation result analysis in prefabricated cabin verifies its good heat dispersion.
