The fully-enclosed self-assembly building is a new sort of facility for outdoor UHV GIS installation,which creates a fully enclosed environment and overcomes the adverse influence of external environment.Hence it can ensure high quality of GIS installation,improve the installation efficiency,and provide good working environment.This paper mainly introduces the development background,basic structure,application mode,engineering application state and social economic benefits of the self-assembly building,which have been successfully used in Anhui-East project and Zhebei-Fuzhou project.Seeing its excellent application outcome,we have decided to popularize the installation of self-assembly building in all the subsequent U HV AC projects in China.%特高压GIS现场安装用全封闭移动式厂房是一种用于户外GIS设备安装的新型工装,能够在工程现场营造一种全封闭的安装环境,克服外部环境对GIS安装的影响,保证GIS安装质量,提高安装效率,并为安装人员提供良好的工作环境.介绍了特高压GIS现场安装用全封闭移动式厂房的研制背景、基本结构形式与应用方式、工程应用情况及社会经济效益等内容.特高压GIS现场安装用全封闭移动式厂房在皖电东送工程、浙北一福州特高压交流输变电工程中进行了试用及全线推广应用,取得了非常好的效果,目前已确定在后续全部特高压交流工程中普遍应用.
