[0026] Furthermore, a primary filter screen 42 is provided on the leftmost side of the photocatalyst purification ventilation device 4 for primary treatment, an activated carbon screen 43 is provided on the right side of the primary filter screen 42 for secondary treatment, a photocatalyst purification screen 44 is provided on the right side of the activated carbon screen 43, an ultraviolet lamp tube 45 is provided on the right side of the photocatalyst purification screen 44, and the ultraviolet light acts on the photocatalyst purification screen 44, a fan 46 is provided on the right side of the ultraviolet lamp tube 45, a rotating rod is provided at the center of the right side of the fan 46, and a motor 47 is connected to the right side of the rotating rod, and the photocatalyst purification ventilation device 4 is symmetrically placed, providing a stable structural foundation for dehumidification inside the distribution cabinet body 1.

[0027] Furthermore, the photocatalyst purification ventilation device 4 is provided with a shell 41 at the outermost side, a ventilation hole 48 is provided at the center of the right side of the shell 41, and a diversion trough 49 is provided at the upper end of the right side of the shell 41, which can divert rainwater to the outside on rainy days and prevent it from entering the inside of the device.

[0028] Furthermore, an air outlet net 51 is provided at the upper end of the hot air drying device 5, a drying trough 52 is provided at the lower end of the air outlet net 51, and an air supply box 53 is provided at the lower end of the drying trough 52, which provides a basis for dehumidification inside the equipment.

[0029] Furthermore, an electric heating tube 521 is provided inside the drying box 52, and an electric heating wire is provided inside the electric heating tube 521. The electric heating wire provides a heat source, so that the electric heating tube generates heat and heats the airflow passing through.

[0030] Furthermore, an air inlet 531 is provided at the lower end of the air supply box 53, a motor 532 is provided at the upper end of the air inlet 531, a rotating shaft 533 is provided at the center of the upper end of the motor 532, and a fan blade 534 is provided at the upper end of the rotating shaft 533 to deliver hot air to the inside of the distribution cabinet body 1.

[0031] Furthermore, an insulating rubber layer is provided on the outer side of the power distribution cabinet body 1, which can prevent the passage of electric current in thunderstorm weather, thereby providing lightning protection.

[0032] Working process: First, when moisture and water droplets are generated inside the distribution cabinet body 1 during the plum rain weather, the motor 532 inside the hot air drying device 5 at the lower end of the distribution cabinet body 1 starts to work, driving the rotating shaft 533 at the center of the upper end, and at the same time, the rotating shaft 533 drives the fan blades 534 to rotate. During the rotation, air is sucked in from the air inlet 531 at the lower end of the hot air drying device 5, and an air flow is generated inside the air supply box 53 and blown upward. The air flow passes through the drying slot 52, and the electric heating pipe 521 inside the drying slot 52 generates heat through the internal electric heating wire, and the passing airflow is converted into hot air, and then the hot air is blown out to the inside of the distribution cabinet body 1 through the air outlet network 51. The blown hot air can dry and remove the moisture and water droplets generated inside the distribution cabinet body 1 due to the plum rain weather, keep the internal space dry, and increase the service life of the equipment.

[0033] Secondly, when moldy air is generated inside the distribution cabinet body 1 due to humidity during the rainy season, the photocatalyst purification ventilation device 4 drives the rotating rod through the internal motor 47, and the rotating rod drives the fan 46 to generate airflow, so as to inhale the moist air generated inside the distribution cabinet body 1 due to the rainy season. The inhaled air is first processed once through the primary filter 42, and then processed twice through the activated carbon net 43. Then, the photocatalyst purification net 44 produces strong oxidizing substances under the irradiation of the ultraviolet lamp 45, which decomposes the bacteria in the air, so that the inside of the distribution cabinet body 1 will not produce mold due to the humidity of the rainy season, and the air inside the distribution cabinet body 1 will be kept clean and fresh, without the need for manual cleaning, thus saving labor. In thunderstorms, the insulating rubber layer on the outside of the distribution cabinet body 1 can prevent the passage of current, thereby providing lightning protection.
