Problems solved by technology

[0002] The exhaust device of the power distribution cabinet used in the existing tunnel site is generally installed on the top of the cabinet. When the ambient temperature in the cabinet is too low, it is easy to generate condensation and affect the performance of the electrical appliances in the cabinet.
In addition, after the air inlet on the side of the power distribution cabinet is blocked, the spare parts of the dust filter are not easy to replace
Therefore, it is difficult for the power distribution cabinet to meet the requirements of places with high protection requirements such as tunnels in terms of ventilation and protection levels.

Embodiment Construction

[0013] Such as Figure 1~3 As shown, the present invention, that is, a waterproof and dustproof power distribution cabinet, includes a cabinet body 100, an air inlet 6 and an air exhaust port 5 arranged on the cabinet body 100, and an exhaust cabinet installed on the air inlet 6 Internal hot and humid gas, cooling axial flow fan 3. The air outlet 5 cooperates with the air inlet 6 to replace the hot and humid air in the cabinet body 100 . The air inlet 6 sends air to the cabinet through the blower fan 3 installed at the air inlet.

[0014] Both sides of the cabinet body 100 adopt upper and lower split compartments 8 and 9 structures, and the air inlet 6 is arranged on the lower

[0015] On the inner wall surface of the interlayer 9 , the air outlet 5 is arranged on the inner wall surface of the upper interlayer 8 .

[0016] The upper and lower compartments 8,9 are all covered with waterproof partitions 10 on which shutters 13 are provided, and the positions of the air outlet...

Abstract

Disclosed a water-proof dust-proof power distribution cabinet comprises a cabinet, and an axial axialflown fan. Wherein, the two sides of cabinet both utilize the upper-lower division interlayer structure; the air inlet is arranged on the inner wall of lower separated layer and the air outlet is arranged on the inner wall of upper separated layer while the upper and lower separated layers are both covered water-proof clapboard with Persian blinds; and the position of air outlet and air inlet are individually relative to its Persian blinds to form upper-lower differential height. And an intelligent temperature-humidity controller and a heater are arranged in the cabinet while a replace slot of dust filtration net is arranged over the air outlet and the air inlet for replacing the dust filtration net more easily. The invention also arranges a internal air channel on the two sides of power distribution cabinet while the air inlet and the air outlet both have the dual-water-proof measure and the dust filtration net is arranged to solve the problem of aeration and protection. In addition, the intelligent temperature-humidity controller can detect and control the temperature and humidity to prevent the effect on the appliance elements caused by the dew generated by over lower temperature and the higher temperature.

Description

technical field [0001] The invention relates to a waterproof and dustproof power distribution cabinet used in places with high protection requirements such as tunnels. Background technique [0002] The exhaust device of the power distribution cabinet used in the existing tunnel site is generally installed on the top of the cabinet. When the ambient temperature in the cabinet is too low, it is easy to generate condensation and affect the performance of the electrical appliances in the cabinet. In addition, after the air inlet on the side of the power distribution cabinet is blocked, it is not easy to replace the spare parts of the dust filter. Therefore, it is difficult for the power distribution cabinet to meet the requirements of places with high protection requirements such as tunnels in terms of ventilation and protection levels. Contents of the invention [0003] The purpose of the present invention is to provide a waterproof and dustproof power distribution cabinet w...
