Abstract: In order to guarantee the installation environment of gas insulated switchgear（GIS）and improve the installation quality,this paper innovatively explores a set of smart inflatable dustproof shed,which mainly includes inflatable dustproof shed and smart purification device,and according to the requirement of the filed. The dustproof shed can provide a good installation environment for dust-free installation of GIS on site,and the smart purification device can monitor data including the temperature,humidity,cleanliness and on-site installation image,display on the local screen,and can also transmit data to the digital management platform through the encrypted network,employing two-layer management concept,which can realize both the remote and on-site control of GIS installation. When the installation environment does not achieve the requirements,the intelligent purification device will send an alarm signal in time,and the installation will be stopped in time.The installation will continue after the environment qualified,ensuring GIS installation environment and quality.
