[0042] Hereinafter, the present utility model will be described in detail with reference to the drawings and in combination with the embodiments

[0043] This embodiment relates to a spliced high and low voltage switchgear. In terms of the overall structure, as Figure 1 and Figure 2 shown, it includes columns 1, partitions 2, connectors 3, and component racks 4

[0044] Among them, multiple spliced columns 1, the number of columns 1 is four, and they form a rectangle. Multiple vertically arranged partitions 2 are respectively installed on the back and both sides of the rectangular columns 1. Connectors 3 with the same number as the partitions 2 fix the partitions 2 on the columns 1. Multiple vertically arranged component racks 4 are installed on both sides of the rectangular columns 1, and components are installed on the component racks 4

[0045] It is worth mentioning that the columns 1 serve as the keel of the distribution cabinet, are arranged vertically and parallel to each other to form a rectangle. The two sides of the partition 2 are respectively installed on two adjacent columns 1, located on the back and two sides of the rectangle. The distribution cabinet is formed in this way. The setting of the connector 3 can facilitate the installation of the partition 2 and increase the strength of the partition 2 to avoid deformation. The component rack 4 is located inside the four columns 1 and is installed on the columns 1 on two sides. The components can be installed on the component rack 4 to facilitate the installation of the components.

[0046] Based on the above overall introduction, an exemplary structure of the spliced ​​high and low voltage distribution cabinet of this embodiment is as follows: Figure 2 and Figure 3 As shown, the column 1 is composed of multiple pipes 5, one end of each pipe 5 is set to an inwardly narrowing trapezoid, and the trapezoid is inserted into another pipe 5. The partition 2 is composed of a back plate 6 installed on the back and side plates 7 installed on both sides. Sealing strips are provided between the multiple partitions 2.

[0047] Specifically, the back panel 6 of this embodiment is longer and the side panel 7 is square, so the side panel 7 is directly fixed to the column 1 by screws, and the back panel 6 is installed on the column 1 through the connector 3. The purpose is to reduce the weight of the distribution cabinet and facilitate transportation and assembly. Of course, according to the size of the distribution cabinet, the connector 3 can also be provided on the side panel 7. The side panel 7 is installed on the column 1 through the connector 3, which can improve the overall strength of the distribution cabinet. The sealing tape is a common sealing material in the prior art and can be directly installed on two adjacent partitions 2. Therefore, it is not shown in the figure. Different numbers of pipes 5 can be spliced ​​according to the height of the distribution cabinet. Multiple pipes 5 are inserted into each other to form a column 1. The trapezoidal part is smaller than the inner diameter of the pipe 5, so it can be inserted, and the part is an interference fit to ensure the insertion strength of the pipe 5, thereby improving the strength of the column 1 and avoiding deformation.

[0048] As a preferred embodiment, Figure 4 As shown, in this embodiment, the connector 3 includes a crossbeam 301 fixedly disposed between the two upright posts 1, a reinforcing rib 302 vertically disposed on the crossbeam 301 to increase the strength of the back panel 6, and a Z-shaped plate 303 to facilitate mounting the back panel 6 on the reinforcing rib. A U-shaped plate 304 is fixedly disposed on the crossbeam 301, and the two side panels 7 of the U-shaped plate 304 are fixedly connected to the crossbeam 301 and the reinforcing rib 302, respectively.

[0049] It should be noted that multiple crossbeams 301 are arranged along the height direction of the column 1, and threaded holes 9 are opened on the crossbeam 301, and strip holes 8 are opened on the column 1. The crossbeam 301 can be fixed to the column 1 by inserting bolts into the strip holes 8 and screwing them with the threaded holes 9. The U-shaped plate 304 is installed on the crossbeam 301 with the same structure. Multiple ones can be installed along the length direction of the crossbeam 301 to increase the connection points of the back plate 6, thereby enhancing the strength of the back plate 6. The Z-shaped plate 303 and the reinforcement rib 302 have the same length and are also connected by strip holes 8 and threaded holes 9, and then vertically installed on the U-shaped plate 304. The back plate 6 is installed on the Z-shaped plate 303 by bolts. The arrangement of the Z-shaped plate 303 in this way can provide reserved space, which is convenient for personnel to tighten the bolts during assembly.

[0050] As a preferred embodiment, Figure 5 As shown, in this embodiment, component rack 4 includes support beams 401 fixedly mounted on columns 1 on either side of a rectangle, and span beams 402 for mounting components. The ends of span beam 402 are mounted on support beams 401 on either side of the rectangle. Support beams 401 are provided with a plurality of grooves 403 arranged in an array, and span beams 402 are positioned within grooves 403. Span beams 402 can be mounted at any position on support beam 401 through these grooves.

[0051] It should be noted that the support beams 401 are located on the two columns 1 on both sides of the rectangle and are arranged horizontally. The cross beams 402 are installed between the support beams 401 on both sides. Multiple cross beams 402 can be installed according to the situation. In this embodiment, there are two cross beams. The two cross beams 402 are set in the grooves 403, which can prevent the cross beams 402 from moving their own positions. The cross beams 402 can adjust the distance between them according to the positions of different grooves 403, so that components can be installed conveniently. Such a setting can help air circulation, thereby achieving a cooling effect.

[0052] As shown in the figure, the columns 1, connectors 3, component racks 4, and partitions 2 of this embodiment are each provided with strip holes 8 and threaded holes 9. Bolts are passed through the strip holes 8 and screwed into the threaded holes 9. Cabinet doors 10 are rotatably mounted on the columns 1 in the relative position of the back panel 6. The number of cabinet doors 10 is the same as the number of back panels 6.

[0053] Specifically, like the strip holes 8 and threaded holes 9 opened on the above-mentioned beam 301 and column 1, each connection of the entire distribution cabinet is fixed in this way, which facilitates the disassembly and assembly of the equipment and the use of tools, ensuring that the equipment can be used in different venues. The positions of the cabinet doors 10 and the back panels 6 are arranged relatively, and the number of cabinet doors 10 is the same as the number of back panels 6, and they are arranged vertically to ensure that they can be easily transported after removal, thereby improving the versatility of the distribution cabinet. The cabinet doors 10 can be installed on the column 1 by means of buckles and hinges. Buckles and hinges are common assembly parts, so they are not shown in the figure.

[0054] The spliced ​​high and low voltage distribution cabinet in this embodiment improves the adaptability and utilization efficiency of the distribution cabinet through the spliced ​​design of the column 1, partition 2 and connector 3; the design of the trapezoidal connecting pipe 5 simplifies the assembly process and enhances the structural stability; the use of the reinforcing ribs 302 and the Z-shaped plate 303 improves the overall structural strength of the distribution cabinet and facilitates the installation of the back panel 6; the U-shaped plate 304 provides an additional support point, which enhances the connection strength between the beam 301 and the reinforcing rib 302; the design of the component rack 4 makes the installation of the components more stable and convenient for maintenance and replacement; the design of the groove 403 provides a flexible installation position for the cross beam 402, which facilitates the flexible arrangement of the components; the design of the strip hole 8 and the threaded hole 9 makes the connection of the components more secure and improves the stability and reliability; the setting of the cabinet door 10 facilitates the observation and maintenance of the interior of the distribution cabinet while maintaining the sealing.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
