The dehumidification mechanism is provided to extract moisture from the electrical cabinet, which can effectively control the humidity of the equipment, extend the service life of the equipment, improve the operating efficiency of the equipment, and reduce the cost of maintenance and replacement. Removing external moisture at the air inlet of the electrical cabinet can reduce the aging and corrosion rate of components, thereby improving the performance of the equipment. The dust suction mechanism is provided to remove dust from the electrical cabinet. Dust accumulated in electrical equipment may reduce the insulation distance between components, thereby increasing the failure rate of the equipment. Cleaning the dust in the electrical cabinet can avoid this situation and reduce the failure rate of the equipment.

[0026] The dehumidification mechanism includes a frame fixedly connected to the electrical cabinet, wherein two cavities are arranged in the frame, filter boxes are placed in the cavities, and the two filter boxes are respectively equipped with coarse-pore silica gel and fine-pore silica gel.

The coarse-pore silica gel and the fine-pore silica gel are arranged so that the coarse-pore silica gel and the fine-pore silica gel can be used to absorb moisture in the gas according to the different humidity in the external air. The coarse-pore silica gel has a higher adsorption capacity when the relative humidity is high, and the fine-pore silica gel has a higher adsorption capacity than the coarse-pore silica gel when the relative humidity is low. Then, the coarse-pore silica gel and the fine-pore silica gel can be used to absorb moisture according to the low humidity in the control, which is beneficial to improving the dehumidification quality and protecting the electrical components in the electrical cabinet.

[0030] According to the embodiments, the humidity sensor detects the humidity of the external environment, the exhaust fan starts to discharge the gas in the electrical cabinet, and then the motor a starts to drive the incomplete gear ring to rotate forward or reverse. When the incomplete gear ring is meshed with the gear, the valve on the connecting pipe can be opened according to the humidity conditions. When the humidity is too high, the coarse-pore silica gel is used to absorb moisture in the air. When the humidity is too low, the fine-pore silica gel is used to absorb moisture.
