Furthermore, the front end and the rear end of the base are provided with a plurality of ventilation holes, so that convection is formed, and the wet air in the base can be conveniently discharged.

Furthermore, a side door is arranged on one side of the base, and when the humid air in the base is too much, the side door can be opened to discharge the humid air.

Further, the side wall of the civil foundation is provided with grids, so that moisture in the cable trench can be further discharged.

The dehumidifier is adopted, so that the high-humidity problem in the box body can be fundamentally solved, the energy consumption of the dehumidifier is far lower than that of a heater used in the traditional technology, and the purposes of energy conservation and emission reduction are achieved.

Compared with the prior art, the utility model has the advantages of it is following:

The utility model discloses dampproofing collection accuse cabinet of HGIS, excellent performance in the aspect of the dehumidification effect also has corresponding improvement in the aspect of energy saving and consumption reduction simultaneously. The method has strong engineering feasibility for solving the condensation problem of the prior 500kV HGIS control cubicle, and has reference significance for the moisture prevention of the HGIS control cubicle of the transformer substation in a high-temperature and high-humidity area by related moisture prevention principles and improvement measures.
