[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The most critical factor for the normal operation and transmission of electricity in a power plant is electrical equipment. Electrical appliances are used in all aspects of our study, work and life, so the importance of electrical equipment is self-evident. When the motor equipment is working, it needs to be in a dry environment to ensure the normal operation of the electrical equipment. At this time, an electrical equipment dehumidification mechanism will be used.

[0003] The dehumidification mechanism is usually composed of a box, an electric fan and an adsorption component. The air inside the box is discharged to the outside through the electric fan. During the discharge process, the adsorption component is generally composed of an activated carbon plate, which directly adsorbs water in the air, thereby achieving dryness inside the box and ensuring the normal operation of electrical equipment. However, when the outside air is in an environment with relatively humid air, the effective time of the activated carbon plate is shorter, which shortens the time for the adsorption component to reach saturation, making it difficult to prevent the entry of outside air, resulting in the need for staff to frequently replace the adsorption component.

[0026] Reference Figure 1A support plate 6 is fixedly installed on one side of the box body 1, and the inner wall of the support plate 6 is in contact with the surface of the connecting pipe 306. By providing the support plate 6, the connection area between the connecting pipe 306 and one side of the box body 1 can be increased, and the support plate 6 can support the connecting pipe 306, thereby increasing the stability of the connecting pipe 306 when working;

Start the vacuum pump 302 and the compressor 305 through an external power supply. The air in the inner cavity of the box body 1 is sucked into the first air outlet pipe 303 through the vacuum pump 302, and enters the second air outlet pipe 304 from the first air outlet pipe 303. The air entering the second air outlet pipe 304 is cooled by the compressor 305, so that the moisture in the air begins to condense into water droplets. The condensed water droplets will move to the inclined tube 307 under the action of their own gravity, and the inclined tube 307 will transport the water droplets to the collection box in the inner cavity of the connection box 308. In 309, the water droplets are collected in a centralized manner, and the separated gas enters the connecting pipe 306. The air passes through the filter frame 310 and contacts the activated carbon plate. The activated carbon plate adsorbs the water in the air, thereby achieving secondary filtration of the moisture contained in the air, further ensuring the dehumidification effect of the air and keeping the air dry. The dried gas flows back to the inner cavity of the box body 1 to complete the dehumidification of the electrical equipment. The activated carbon plate needs to be replaced after long-term use. The threaded connection with the arc plate 4 is cancelled by the positioning rod 5, so that the sealing plate 311 can drive the filter frame 310 to move out of the inner cavity of the connecting hole 312, thereby achieving the replacement of the activated carbon plate.
