Abstract: This paper takes Sutong gas-insulated metal-enclosed transmission line (GIL) project’s pipe corridor as a sample of confined space, the difficulty of installing and constructing GIL equipment in the restricted space is analyzed, and the design principles of the operating platform device under this working condition are introduced. This paper systematically expounds the composition, use function, construction process and other contents of the mobile closed work platform device for GIL installation in a restricted space in combination with the actual application of the project, and analyzes the efficiency advantages of the device by comparison with the same type of equipment, and the application effect of the scheme is further verified.
Key words: gas insulated metal enclosed transmission line (GIL) installation; operating platform device; efficacy
