Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a vertical busbar reinforcement structure of a power distribution cabinet. Background Art

[0002] The vertical busbar of the distribution cabinet refers to the busbar arranged vertically along the cabinet body. It is a conductive copper or aluminum busbar used to distribute electric energy. It connects the upper and lower circuit breakers, contactors, etc. to form a main current transmission structure. It is one of the key components in the power grid. In the power system, the busbar system is responsible for transmitting and distributing electric energy between electrical equipment. When a short circuit occurs in the power system, a huge short-circuit current will be generated in a very short time. This short-circuit current will generate a strong electric force on the busbar, which may cause severe mechanical stress on the busbar system, including deformation, distortion and even fracture, which will lead to the paralysis of the entire power system. Therefore, the structure of the busbar system must be able to resist the point force generated by the short-circuit current to ensure the stability and safety of the power system.

[0003] The vertical busbars of the existing distribution cabinet outlet solution are only fixed to the back of the outlet cabinet by busbar clamps. When a short circuit occurs, the short-circuit electric force between the vertical busbars will be completely applied to the busbar clamp body, and the side panels of the existing vertical busbar system cannot provide structural support for the busbar clamp, which is not conducive to improving the ability of the vertical busbar system to resist the short-circuit current electric force. Utility Model Content

[0004] The utility model provides a vertical bus reinforcement structure of a power distribution cabinet, which can effectively support the bus clamp, strengthen the overall structural strength of the bus system, and better resist the short-circuit current electromotive force.

[0006] A vertical busbar reinforcement structure for a power distribution cabinet, characterized in that it includes a left side plate, a right side plate, a busbar clamp and a reinforced mounting beam, the upper edges and lower edges of the left side plate and the right side plate are respectively bent outward to form a first bending surface and a second bending surface, the rear edges of the left side plate and the right side plate are bent outward to form a third bending surface, the third bending surface is provided with evenly distributed openings, the front edges of the left side plate and the right side plate are bent three times to form a fourth bending surface, a fifth bending surface and a sixth bending surface, the fourth bending surface is provided with openings in an array form; the reinforced mounting beam is fixedly connected to the fourth bending surfaces of the left side plate and the right side plate, respectively, the reinforced mounting beam includes an upper plane, a lower plane and a vertical plane, the vertical plane is provided with mounting holes for installing the busbar clamp.

[0007] Technical principle: The reinforced installation beam has a U-shaped structure and has good structural strength. By introducing the reinforced installation beam, the structural strength of the vertical busbar side plate is improved; the reinforced installation beam is connected to the left and right side plates to form a stable structure as a whole.

[0008] Beneficial effects: Through the U-shaped reinforced mounting beam and the connection between the reinforced mounting beam and the left and right panels, a high-strength vertical busbar overall structure is formed.

The busbar clamp is fixed on the vertical surface of the reinforced mounting beam, which is convenient for installation. Such an overall structure can provide reliable fixation and support for the busbar, and effectively resist the short-circuit current electromotive force.

[0009] Furthermore, it also includes a metal protective cover arranged at the bottom of the busbar system.

[0010] Beneficial effect: Prevent small animals such as rodents from entering the busbar system, ensuring the safety of the system.

[0011] Furthermore, there are at least two reinforced mounting beams.

[0012] Beneficial effect: The use of multiple reinforced mounting beams can disperse stress distribution and prevent local stress overload.

[0013] Furthermore, the left side plate and the right side plate are provided with evenly distributed heat dissipation holes with a diameter of 20 mm, and the metal protective cover is provided with evenly distributed strip heat dissipation holes with a width of 10 mm.

[0014] Beneficial effects: Improved air circulation and enhanced heat dissipation performance of the busbar system.

[0025] Embodiment 1

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, a vertical busbar reinforcement structure of a power distribution cabinet includes a left side plate 1, a right side plate 2, a busbar clamp 3, a reinforced mounting beam 4 and a metal protective cover 5. Among them, the upper edge and the lower edge of the left side plate 1 and the right side plate 2 are bent outward to form a first bending surface 6 and a second bending surface 7 respectively, and the rear edge of the left side plate 1 and the right side plate 2 is bent outward to form a third bending surface 8, which increases the structural strength of the side plate. The third bending surface 8 is provided with evenly distributed circular holes with a center distance of 50mm and a diameter of 5.2mm, which can enhance the installation adaptability of the busbar system. The front edges of the left side plate 1 and the right side plate 2 are bent three times to form a U-shaped structure, including a fourth bending surface 9, a fifth bending surface 10 and a sixth bending surface 11. The fourth bending surface 9 is provided with an array of openings for installing the reinforced mounting beam, and the sixth bending surface 11 is provided with an array of square holes for hanging the busbar transparent shield. There are multiple reinforcing mounting beams 4, which are bent at the upper and lower edges to form a U-shaped structure including an upper plane, a lower plane and a vertical plane, and have good structural strength. Its vertical plane is parallel to the fourth bending surface 9 of the left side plate 1 and the right side plate 2, respectively. The reinforcing mounting beam 4 can be fixed to the fourth bending surface 9 of the left side plate 1 and the right side plate 2 using self-tapping screws to complete the fixed connection between the reinforcing mounting beam 4 and the side plate of the busbar system. The use of multiple reinforcing mounting beams can effectively improve stress distribution and prevent local stress overload. The vertical surface of the reinforcing mounting beam 4 is provided with multiple mounting holes for installing the busbar clamp 3. The bottom of the busbar system is provided with a fully enclosed metal protective cover 5, which can effectively prevent small animals such as rodents from entering the busbar system by mistake.

[0027] Through the above design, the busbar clamp, multiple reinforced mounting beams and the left and right plates form a high-strength structural frame, which has a stable and reliable support and fixation effect on the busbar, enhances the bending and torsional strength of the busbar system, and improves the busbar system's ability to resist short-circuit current electromotive force. Its actual use is as follows Figure 4 shown.

[0028] The sides of the left plate 1 and the right plate 2 are provided with evenly distributed heat dissipation holes with a diameter of 20 mm, and the metal protective cover 5 at the bottom is also provided with evenly distributed strip heat dissipation holes with a width of 10 mm, which improves the heat dissipation performance of the busbar system.
