摘要: 变电站的建设模式正向模块化设计和装配式施工转变。对于沉降敏感地区,变电站配电装置室一般采用现浇混凝土架空结构,其室内电力设备安装在现浇混凝土架空结构上。而现浇混凝土的架空结构方案已无法满足变电站"标准化设计、工厂化加工、装配式建设"的要求。为此提出了一种新型复合材料架空结构体系,可用于变电站配电装置室室内电力设备基础。该结构体系由模块化的纵梁、横梁、立柱、面板等构件组成,除横梁采用型钢外,其他构件采用模压和拉挤的复合材料制造,具有建设周期短、开洞方便、易于更新改造等优点。通过系统介绍该新型结构体系的整体方案与设计,初步论证了工程实际荷载条件下的可行性。Abstract: The construction mode of substations is changing to modular design and assembly construction. As an important facility for distributing electrical energy, substations in settlement-sensitive areas generally adopt cast-in-place concrete overhead structures, and their indoor electrical equipment is installed on the cast-in-place concrete overhead structure. The cast-in-place concrete overhead structure can no longer meet the requirements of "standardized design, factory processing and assembly construction" of substations. The paper proposed a new composite overhead structure system that could be used as a foundation for indoor electrical equipment in substation distribution rooms. The structure system consists of modular longitudinal beams, cross beams, columns, panels, and other components, except for the cross beams which are made of steel, other components are made of molded and pultruded composite materials, which have the advantages of the short construction period, convenient hole opening and easy renewal and transformation. The overall scheme and design of the new structural system were systematically introduced in the paper, and the feasibility of the project under actual loading conditions was initially demonstrated.
