[0032] The working principle and use process of the utility model are as follows: when in use, the user starts the fan 4, the input end of the fan 4 draws air from the outside of the box body 2, and when the air enters the box body 2, the filter block 3 filters the back side and impurities in the air to prevent dust from entering the cabinet 1, and then the fan 4 transports the filtered air to the inside of the condensation plate 10, and at the same time starts the refrigerator 9, and cools the condensation plate 10 through the cooling end of the refrigerator 9. When the air passes through the condensation plate 10, the moisture in the air forms condensed water on the surface of the condensation plate 10, dehumidifies and cools the air, and then the dehumidified air is transported to the inside of the pipeline 8 through the connecting pipe 7, and then by The nozzle 16 sprays the interior of the cabinet 1 to prevent dust from adhering to the surface of the components, and at the same time cools and dehumidifies the cabinet 1. At this time, the components inside the cabinet 1 can be protected from dust, and then the card block 6 is pushed to the left. The card block 6 moves to the left and drives the limit block 21 to move outward. The limit block 21 moves to the left to stretch the tension spring 20, and then the cross block 5 is pulled upward to make the cross block 5 and the card block 6 rotate clockwise around the hinge to disengage the card block 6 from the card slot 18, so that the cross block 5 is separated from the box body 2, and then the filter block 3 is pulled upward to separate the filter block 3 from the box body 2, and the filter block 3 is disassembled and replaced. The operation during installation can be reversed to fix the position of the filter block 3.

[0033] To sum up: the power distribution cabinet protection device, through the coordinated use of the cabinet body 1, the box body 2, the filter block 3, the fan 4, the cross block 5, the card block 6, the connecting pipe 7, the pipeline 8, the refrigerator 9 and the condensing plate 10, solves the problem that the components inside the power distribution cabinet cannot be protected from dust during use. When dust enters the power distribution cabinet, it is easy for the dust to adhere to the components, resulting in poor contact of the components and causing a short circuit, thereby affecting the normal operation of the components.
