Description

Technical Field

[0001] The utility model relates to the field of low-voltage drawer switch cabinets, in particular to a dustproof low-voltage drawer switch cabinet. Background Art

[0002] A drawer-type switch cabinet is a switch cabinet with a closed casing made of steel plates. The electrical components of the incoming and outgoing line circuits are installed in withdrawable drawers, forming a functional unit that can complete a certain type of power supply task.

[0003] In the related art, a number of heat dissipation holes are generally provided on the side of the cabinet body for dissipating heat. Dust can easily penetrate into the switch cabinet through the heat dissipation holes. If the maintenance and cleaning of the drawer-type switch cabinet are not timely or thorough, the dust attached to the cabinet wall, guide rails and other surfaces will gradually accumulate. Some dust is water-absorbent and will destroy the insulation strength of electrical equipment after being damp, posing a safety hazard. Utility Model Content

[0032] It should be noted that the two mounting boxes 3 are respectively fixedly connected to the inner top wall and the inner bottom wall of the outer box 2, and the low-voltage drawer switch cabinet body 1 is fixedly connected between the bottom of the upper mounting box 3 and the upper surface of the lower mounting box 3, so that the low-voltage drawer switch cabinet body 1 is stably installed inside the outer box 2, and the left and right sides of the mounting box 3 are provided with a first adsorption port 9, and the bottom of the upper mounting box 3 and the upper surface of the lower mounting box 3 are provided with a second adsorption port 10, so that the activated carbon plate 5 adsorbs dust and moisture inside the outer box 2 through the first adsorption port 9 and the second adsorption port 10, and the back of the outer box 2 is fixedly connected with a pipe 11, and an exhaust fan 12 is fixedly connected between the inner top wall and the inner bottom wall of the pipe 11, and the heat inside the outer box 2 is extracted by the exhaust fan 12, so as to achieve a heat dissipation effect, and the back of the outer box 2 is provided with a first heat dissipation port 13, and the pipe 11 is connected to the inside of the outer box 2 through the first heat dissipation port 13, and the right side pipe 1 The first heat dissipation port 13 on the right side wall of the outer box 2 is connected to the interior of the outer box 2. The exhaust fan 12 can extract the heat in the outer box 2 through the setting of the first heat dissipation port 13. The first dust shielding net 14 is fixedly connected to the inner side of the first heat dissipation port 13.
