GIS cavity internal humidity detection method considering installation environment factors

The invention relates to a GIS cavity internal humidity detection method considering installation environment factors. The method comprises the following steps: S1, obtaining installation environmentparameters and GIS body parameters; S2, calculating the moisture mass and the total moisture mass of the gas in a GIS cavity according to the obtained parameters; S3, performing drying treatment on the GIS cavity, and calculating the mass of residual moisture of the gas in the cavity after the drying treatment; and S4, according to the obtained moisture mass and total moisture mass of the gas in the GIS cavity and the residual moisture mass of the gas in the cavity after drying treatment, calculating to obtain the relative humidity in an outlet cavity in a balanced state. According to the invention, the humidity in the GIS cavity in different installation environments can be accurately detected, and the reliability of GIS installation is ensured. 本发明涉及一种考虑安装环境因素的GIS腔内湿度检测方法，包括以下步骤：步骤S1:获取安装环境参数和GIS本体参数；步骤S2:根据得到的参
