Abstract Aiming at the problem that gas insulated switchgear (GIS) is affected by environmental temperature and humidity during installation, which leads to high residual moisture content of gas chamber after installation and needs to be re-installed, a calculation method of residual moisture content of GIS gas chamber considering installation environmental factors is proposed. Firstly, the GIS installation process is formulated. Secondly, the total moisture component of the gas chamber after sealing is calculated. Finally, the moisture content of the balanced SF₆ is calculated according to the installation process. The simulation and experimental results show that the moisture content of SF₆ in the gas chamber increases with the increase of installation environment temperature and relative humidity. The calculated value is in good agreement with the experimental value with the increase of installation environment temperature and humidity, and the relative error is less than 15%. It can better predict the change of GIS residual moisture content under the influence of installation environment temperature and humidity, which is conducive to the selection of suitable installation environment in engineering.

Key words： gas insulated switchgear (GIS) installation environment temperature and humidity moisture content computational model
