Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of low-voltage power distribution cabinets, in particular to an intelligent temperature control dustproof low-voltage power distribution cabinet. BACKGROUND

[0002] Low-voltage power distribution cabinets install circuit breakers, contactors, transformers and other components to control and protect circuits. Some cabinets may also be equipped with reactive power compensation devices, capacitor banks and other equipment to improve the power factor and energy-saving effect of the system. Low-voltage power distribution cabinets have many circuit components, and a large amount of heat is generated in the cabinet over a long period of time. Solving the problem of heat dissipation is a key factor in maintaining the stability and safety of low-voltage power distribution cabinets.

[0003] For example, a low-voltage power distribution cabinet disclosed in Chinese Patent No. CN208508272U includes a low-voltage power distribution cabinet body, a plurality of heat dissipation holes on the low-voltage power distribution cabinet body, a rainproof protruding cover on the heat dissipation holes, a lower outlet on the lower side of the low-voltage power distribution cabinet body, an additional cover that can be installed on the heat dissipation holes, a slanted connecting part connected to the additional cover, a clamping part connected to the slanted connecting part, and two clamping pieces in the clamping part. The clamping gap between the two clamping pieces can clamp the wall of the low-voltage power distribution cabinet body. The additional cover is a slanted cover that can be fixed on the low-voltage power distribution cabinet body through the heat dissipation holes. The additional cover can prevent rainwater from entering the lower outlet on the lower side of the low-voltage power distribution cabinet.

[0004] For example, a low-voltage power distribution cabinet disclosed in Chinese Patent No. CN215071272U includes a power distribution cabinet box, a primary heat dissipation mechanism and a secondary heat dissipation mechanism. The power distribution cabinet box is provided with square holes symmetrically on the side walls on both sides of the box door, and the bottom plate inside the power distribution cabinet box is provided with a groove. The primary heat dissipation mechanism is arranged on the power distribution cabinet box, and the rotation of the baffle is controlled by the electric bearing to control the air circulation inside the power distribution cabinet box. The secondary heat dissipation mechanism is arranged on the power distribution cabinet box to further dissipate heat inside the power distribution cabinet box. By setting multiple heat dissipation mechanisms, the inside of the power distribution cabinet box can be effectively and hierarchically dissipated. The control unit can also transmit the over-temperature warning information to the control center and prompt the staff around the power distribution cabinet through the buzzer, avoiding unnecessary accidents.

[0005] For example, Chinese patent CN221408056U discloses a moisture-proof and heat-dissipating low-voltage distribution cabinet, which includes a cabinet body, a cabinet door rotatably connected inside the cabinet body, a heat dissipation plate connected inside the cabinet body, a heat dissipation fan rotatably connected inside the heat dissipation plate, a reinforcing partition snapped into the cabinet body, an L-shaped plate connected to one side of the reinforcing partition, a concave plate connected to the side of the cabinet body, the L-shaped plate snapping into the concave plate, and a guide rod rotatably connected inside the concave plate. By setting up the reinforcing partition, L-shaped plate, concave plate, cam, locking block, and fixing rod, and through the cooperation between the spring, cam, and locking block, the reinforcing partition can achieve a quick assembly function with the cabinet body, thereby protecting the bottom of the cabinet body and preventing ground moisture from entering the low-voltage distribution cabinet. Inside the cabinet, to prevent rust from forming at the bottom, ensuring its normal operation; to maintain proper heat dissipation, most power cabinets are equipped with ventilation holes to assist in the convection of internal and external air, thereby reducing the heat inside the cabinet. However, the convective air contains dust particles. If some exposed components inside the cabinet are covered by dust and absorb moisture from the air, it will corrode some of the exposed components. Over time, this may lead to reduced insulation, short circuits, grounding faults, and even the risk of electric shock. Some existing low-voltage power cabinets are not convenient for cleaning the dust generated by heat dissipation, and cannot simultaneously achieve heat dissipation and dust removal, making the power cabinet prone to failure.
