哈密南±800 kV换流站换流区域建构筑物结构设计

换流区域为±800 kV特高压直流换流站的核心区域,是换流站设计的重点和难点。基于哈密南 ±800 kV换流站工程技术条件,论述了换流区域主要建构筑物的结构设计特点。结合国内已投运的±800 kV换流站设计、施工和运行经验,按照技术先进、经济合理、安全可靠、施工方便的原则,总结了±800 kV换流站换流区域包括阀厅、控制楼内电缆夹层、空冷器保温室、换流变压器基础及搬运轨道、换流变压器进线构架等建构筑物结构选型及实施方案,以期对后续特高压直流换流站结构设计提供指导和借鉴作用。

Structural Design of Buildings and Structures on Converter Transformer Area of ±800 kV Converter Station in South Hami

Converter transformer area is the core area in ±800 kV UHVDC converter station, and it is also the focus and difficult part for the station design. According to the engineering technical conditions of the Hami ±800 kV converter station project, the structural design characteristics of the main buildings and structures in the converter transformer area are introduced. On the basis of the experiences in design, construction and operation of the ±800 kV converter stations that have been put into operation in China, the structure type selection and implementation scheme for the mian buildings in the ±800 kV converter transformer area, including the valve hall, cable interlayer in control building, insulated room for air cooler, converter transformer foundation and railroad foundation, and the incoming-line frame for the converter transformer are summarized in the principle of advanced technology, reasonable economy, safe, reliable and convenient construction, which can be used as a guidance and reference for the structural design of the future UHVDC converter stations.
