变电站槽钢架固定式二次屏柜安装技术研究

Research on installation technology of fixed secondary screen cabinets for substation steel frame

我国经济的高速发展,刺激电力需求进一步加强,而城市化建设进一步凸显了土地资源稀缺的弊端,因此,紧凑型布置的户内变电站得到了广泛应用,为提高电网供电可靠性集成智能化的高重设备的应用创造了广阔的空间。但是,在紧凑型户内变电站建设期间,大量超高、超宽户内设备需要二次转运,尤其是户内的未设电缆层是采用槽钢架固定式屏柜安装的,安装工作难度大且安全风险大。文章对变电站槽钢架固定式二次屏柜安装的技术进行了研究。

With the rapid development of China’s economy, the demand for electric power has been further strengthened, and the urbanization construction has further highlighted the shortage of land resources, so the compact indoor substation has been widely used. It creates a wide space for the application of intelligent and integrated high-weight equipment to improve the reliability of power supply. However, during the construction of compact indoor substations, a large number of ultra-high and ultra-wide indoor equipment need to be transported twice, especially the uninstalled cable layer in the household is installed with fxed screen cabinets with channel steel frame, so the installation work is diffcult and the safety risk is great. In this paper, the installation technology of fxed secondary screen cabinet of channel steel frame in substation is studied.
