[0025] The utility model provides a low-voltage protection power distribution cabinet, which dehumidifies and dries the air entering the power distribution cabinet from the outside by means of a dehumidification and drying component arranged inside the power distribution cabinet, so that the air entering the power distribution cabinet for heat dissipation remains dry, and moisture is prevented from entering the internal parts of the power distribution cabinet to rust.

[0026] Figure 1-Figure 3 The structure diagram of a low voltage protection distribution cabinet of the present invention is shown in FIG. Figure 1-Figure 3 In this embodiment, a low-voltage protection distribution cabinet is provided, and its main body includes a distribution cabinet component 100 and a dehumidification and drying component 200 .

[0027] The power distribution cabinet assembly 100 includes a power distribution cabinet body 110 and a power distribution cabinet door 120 disposed at the front end of the power distribution cabinet body 110. A heat dissipation hole 111 is provided on the upper side of the side wall of the power distribution cabinet body 110. Preferably, in this embodiment, a sealing strip 121 is provided on the outer wall of the power distribution cabinet door 120. The sealing strip 121 is made of rubber. The sealing strip 121 disposed on the outer wall of the power distribution cabinet door 120 seals the gap between the cabinet door and the cabinet body to prevent external moisture from entering the cabinet body.

[0028] The dehumidification and drying component 200 includes at least two circular plates 210 vertically arranged on the inner wall of the distribution cabinet body 110, an activated carbon desiccant 220 arranged inside one of the circular plates 210, and a calcium chloride desiccant 230 arranged inside the other circular plate 210. The circular plates 210 are threadedly mounted on the inner wall of the distribution cabinet body 110. Preferably, in this embodiment, the relative outer walls of the distribution cabinet body 110 are provided with heat dissipation holes 111, and a dehumidification and drying component 200 is arranged on the inner side of each heat dissipation hole 111. The two heat dissipation holes 111 enhance the heat dissipation of the cabinet body. A dustproof net 211 is arranged inside the circular plate 210 close to the side of the distribution cabinet body 110. The dustproof net 211 is located on the outside of the activated carbon desiccant 220. The dustproof net 211 arranged inside the circular plate 210 can block external dust and prevent external dust from entering the cabinet body, thereby enhancing the dustproofness of the device. A mounting plate 212 is fixed to the end of one circular plate 210, and an internal thread 213 is provided inside the other circular plate 210. The two circular plates 210 are threadedly connected, and the adjacent circular plates 210 are threadedly installed together under the action of the mounting plate 212 and the internal thread 213. The operator can manually separate the two circular plates 210 later to replace the internal desiccant. A fixing block 214 is fixed to the relative outer wall of the circular plate 210. The fixing block 214 fixed on the outer wall of the circular plate 210 is convenient for the operator to rotate the circular plate 210 through the fixing block 214.

[0029] Combination Figure 1-Figure 3 A low-voltage protection distribution cabinet of the present embodiment is specifically used as follows: when in use, the outside air enters the inside of the distribution cabinet body 110 from the heat dissipation hole 111. After the entering air passes through the activated carbon desiccant 220 and the calcium chloride desiccant 230 in the circular ring plate 210, the moisture inside is dried out by the activated carbon desiccant 220 and the calcium chloride desiccant 230, so that the air entering the distribution cabinet body 110 to be dissipated remains dry, and moisture is prevented from entering the internal rusted parts of the distribution cabinet body 110. At the same time, a dustproof net 211 is also arranged inside the circular ring plate 210. The dustproof net 211 can block the external dust and prevent the external dust from entering the inside of the distribution cabinet body 110, thereby enhancing the dustproofness of the distribution cabinet body 110.

[0030] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
