Fabricated Substation Exploration And Installation Technology

Fabricated substation is to implement substation construction project with a lifecycle design construction idea. It's following "two type and one localized" substation design construction supporting by the state grid corporation, according to the regulations, specification guidelines for the management and technical requirement. The typical design scheme is conducted on the basis of improving design, optimization of the layout and the vertical design. It will effectively reduce the construction area, investment, construction period index, promoting standardized design, standardization construction, reduce the complexity and difficulty of management, and to reduce the occupation of the resource and the effects to the environment and fully implement industrialized production, distribution type construction, achieve resource-saving and environment-friendly and industrialization, distribution type construction, reduce project investment and realize the construction total project life cycle function matching, life coordination, cost balance. This article through to the development of domestic and foreign fabricated substation reference, combining industrialized production, modular equipment development, introduces emphatically fabricated substation building structural system of new designs, adopting the construction market has mature technology, using standard prefabricated component, forming industrialized production mode. Article introduces in detail substation fabricated steel structure housing structure design, from basic structure to door frame, then to steel structure design of each node, roof and wall material selection, adopted the market mature new materials and new technology. Also introduced prefabricated in cable trench and substation assembly factory prefabrication walls, so-called prefabricated by cable is prefabricated in cable trench monomers, each monomer section for "U" glyph ditch body, left, right ditch wall symmetrical and bottom-up gradually contracts narrow, bottom sets arc sink; And fabricated fence so-called precast packaged type namely site prefabricated plug-in factory production base, prefabricated column plug-in prefabricated column and autoclaved processing of lightweight mixes clay board (ALC wallboard), prefabricated column with ordinary based casting based coleorhiza, plug-in prefabricated column made according to size and wall panels ALC designed height customization, its structure similar and casting steel structure, adopt choices. Article reference extensive literature and construction practice, this paper introduces the industrialization fabricated substation steel structure building construction and installation technologies of buildings, fabricated in cable trench, partition wall and modular electrical construction technology. At last, the author combined with 110 kV yangliu substation as an example.This paper expounds systematically fabricated substation design and installation. It has good significance for a substation modular design and fabricated construction.
