Background

The condensation is a pertinacious disease of normal operation and maintenance of various outdoor terminal devices in the era of the internet of things, can cause faults such as false start and short circuit, and brings challenges to the realization of unmanned inspection. In fact, when the ambient humidity exceeds 80%, the adverse effects of corrosion of metal parts, deterioration of electrical insulation performance, and the like are underdeveloped. The formation of condensation is mainly influenced by the following field factors: 1. the surrounding geographical environment of the box body is complex (such as the influence of the altitude and water sources); 2. the box body is not sealed well; 3. seasonal weather effects (such as plum rainy season); 4. naturally cooling every day (the inner wall is cooled to reach the dew point of the air inside in advance); 5. the equipment works intermittently and heats unevenly; the traditional active dew removing methods (such as a dehumidifier and a heater) can not effectively solve the problem of wetting and condensation.
