The pre-set moisture content calculation formula is specifically as follows: wherein d 内 is the indoor moisture content of the power distribution room, φ1 is the indoor relative humidity of the power distribution room, P q,b1 is the water vapor partial pressure of the indoor saturated moist air of the power distribution room, d 外 is the outdoor moisture content of the power distribution room, φ2 is the outdoor relative humidity of the power distribution room, P q,b2 is the water vapor partial pressure of the outdoor saturated moist air of the power distribution room, B is the atmospheric pressure, d 混 is the moisture content after mixing the indoor and outdoor air, and α is the proportion of outdoor air. The method further comprises the following steps: The pre-judgment module is configured to judge whether the internal environment dry-bulb temperature is greater than a pre-set temperature threshold value; if yes, the control is performed on the opening of the blades of the convection air outlet and the cold air extractor air outlet, the cold air extractor is started, and the execution of the acquisition module is returned.
