With the continuous development of my country's economy, urban power grids and power equipment are also undergoing continuous transformation and construction. For the outlet cabinet, it is suitable for power distribution systems in power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries. In order to facilitate the control and processing of the lines, most distribution cabinets are currently equipped with outlet cabinets.

[0003] When low-voltage distribution cabinets are used in flammable and explosive places such as petroleum, chemical, and coal mines, their main function is to protect electrical equipment from the threat of explosion and fire and ensure production safety. However, when dissipating heat, existing low-voltage distribution cabinets usually install cooling fans in the heat dissipation holes of the cabinet. This causes the internal space of the cabinet to be directly connected to the external air. Flammable and explosive gases or particles can easily enter the interior of the cabinet through the heat dissipation holes, exposing the working environment of the electrical equipment to flammable and explosive places. Dangerous factors such as sparks, arcs, and high temperatures inside the electrical equipment will cause the risk of explosion. Therefore, the applicant has made a beneficial design and found a solution to the above problem. The technical solution to be introduced below was produced in this context. Summary of the Invention

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] Reference example Figures 1 to 5 A high-safety explosion-proof low-voltage outlet cabinet includes a support frame 1, side panels 2, a back panel 3, and a cover panel 4. The side panels 2 are inserted on both sides of the support frame 1, the back panel 3 is inserted on the back of the support frame 1, and the cover panel 4 is fixed to the top of the support frame 1 and abuts against the side panels 2 and the back panel 3. The side panels 2, the back panel 3, and the cover panel 4 are all provided with a plurality of equally spaced heat dissipation fins 5. The heat dissipation fins 5 of the side panels 2 and the back panel 3 are provided with a heat dissipation fan 6.

[0025] It is worth mentioning that the support frame 1 is provided with a clearance groove 11 on both sides and the back thereof, and a fixing groove 12 is provided on both sides of the clearance groove 11, and a limiting groove 13 is provided on both sides of the fixing groove 12. The clearance groove 11 provides accommodation space for the side panels 2 and the back panel 3, and the fixing groove 12 is used in conjunction with the fixing block 71. The limiting groove 13 prevents the side panels 2 and the back panel 3 from being separated from the support frame 1;

[0026] It is worth mentioning that the side panels 2 and the back panel 3 are arranged in the make way groove 11, and the side panels 2 and the back panel 3 are provided with a bending plate 7 on both sides, so that the height of the heat dissipation fins 5 is lower than the side surface of the support frame 1, and the bending plate 7 is provided with a fixing block 71, which is inserted in the fixing groove 12, and the fixing block 71 is provided with a limiting block 72 on both sides, which is inserted in the limiting groove 13, and the limiting block 72 is provided with a first sealing strip 73, which abuts the limiting groove 13, and is used to form a sealed structure at the connection between the side panels 2, the back panel 3 and the support frame 1. The material of the side panels 2 and the back panel 3 can be optional. Aluminum, iron, copper and other materials with good thermal conductivity are selected. The bent plate 7 makes the side plate 2 and the back plate 3 concave in the side plate 2 of the support frame 1, so that the height of the heat dissipation fins 5 is lower than the side plate 2 of the support frame 1, reducing the volume of the heat dissipation system. The fixing block 71 is used in conjunction with the fixing groove 12. When the limit block 72 contacts the limit groove 13, the tortuous shape of the limit block 72 is set to reduce the communication between the external air and the internal air. In addition, the first sealing strip 73 further improves the sealing performance of the connection between the side plate 2, the back plate 3 and the support frame 1.

[0027] It is worth mentioning that the side panel 2 is provided with a plurality of wire holes 21, and the wire holes 21 are provided with explosion-proof cable sealing joints 22. The wire holes 21 are convenient for external or internal wires to pass through and connect with other electrical equipment. The explosion-proof cable sealing joints 22 ensure the sealing between the wires and the wire holes 21 to prevent internal gas from entering the cabinet.

[0028] It is worth mentioning that the cover plate 4 is provided with an annular protrusion 41, and the outer wall of the annular protrusion 41 is provided with a second sealing strip 42, which abuts the side plate 2 and the back plate 3. The outer wall of the annular protrusion 41 is located on the inner wall of the side plate 2 and the back plate 3. The tortuous shape reduces the entry of external air into the cabinet, and the second sealing strip 42 improves the sealing of the connection between the cover plate 4 and the side plate 2 and the back plate 3.

[0029] It is worth mentioning that the heat dissipation fan 6 is arranged on the top of the heat dissipation fins 5 .

[0030] When heat is generated inside the cabinet, it is transferred to the side panels 2, back panel 3, and cover panel 4, and then the heat dissipation fins 5 exchange heat with the external flowing air, so that the side panels 2, back panel 3, and cover panel 4 are controlled at a certain temperature. When natural heat dissipation still cannot control the temperature inside the cabinet to continue to rise, the cooling fan 6 starts to draw external air into the two ends of the heat dissipation fins 5, thereby increasing the air flow rate between the heat dissipation fins 5, further improving the heat exchange efficiency of the heat dissipation fins 5, and effectively controlling the temperature rise inside the cabinet.

[0031] The above design solution can enable the product to achieve the advantages of high safety and good heat dissipation effect.

[0032] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
