The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many ways to classify switchgear. For example, according to the installation method of the circuit breaker, it can be divided into removable switchgear and fixed switchgear; or according to the different cabinet structures, it can be divided into open switchgear, metal-enclosed switchgear, and metal-enclosed armored switchgear; according to the voltage level, it can be divided into high-voltage switchgear, medium-voltage switchgear and low-voltage switchgear.

[0003] At present, for the common switch cabinet structure in the market, since multiple air switch modules are required, the installation process of the busbars between different layers is easy to interfere with the switch cabinet itself, and the common common box closed bus duct installation method will obviously increase the internal space requirement of the switch cabinet. For this reason, we propose a modular switch cabinet to solve the above problems. Utility Model Content

[0018] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0019] According to one embodiment of the present invention, Figure 1-Figure 3 Shown.

[0020] As for the overall structure, a combined switch cabinet includes: an upper and lower layered cabinet body 1, the inner wall of the cabinet body 1 is hollow and fixed with a frame structure 2, the frame structure 2 is multi-layered and each layer includes a plurality of spaced beams 3, the top layer is a vertical beam layer 4, and the remaining layers are 3 layers of horizontal beams, the beams 3 on the 3 layers of horizontal beams are also bolted with relatively arranged guide rails, and positioning holes 7 for positioning external open modules are provided at both ends of the guide rails, and a busbar 8 and a busbar clamp 9 are also provided at one end of the frame structure, and the busbar clamp 9 Two of them are bolted relative to each other to form a group and include multiple groups. The busbar clamps 9 of each group correspond to each layer of 3 horizontal beams and are bolted to the frame structure 2. The busbars 8 are multiple columns and vertically pass through each layer of the frame structure 2. Each group of busbar clamps 9 relatively clamps multiple columns of the majority of busbars 8 through adjusting screws 10. An isolating switch 11 is also fixedly installed on the inner wall of the cabinet 1 on the top of the beam 3 on the top layer. A plurality of outgoing line bars 12 are overlapped at the bottom of the isolating switch 11. The outgoing line bars 12 are overlapped one by one with the busbars 8 in each column through copper bars 13.

[0021] Through the above structural layout, firstly, the external circuit breaker module can be positioned and installed by the guide rails on each layer of horizontal beams 3. The guide rail spacing is adjustable, and the beams 3 themselves are multi-hole designed, which can cooperate with the guide rails to meet the fixing requirements of various types of circuit breakers. Similarly, the disconnector 11 is placed on the top layer in the present application. In order to avoid the copper bus 13 required for connecting the outgoing line bus 12 of the disconnector 11 with the bus bar 8 from being exposed, the present application places the beams 3 in the top vertical beam layer 4 vertically, and the copper bus 13 is covered by the beams 3 that are ringed in pairs, so as to avoid unnecessary interference caused by the exposure of the copper bus 13, and further reduce the burden on other installation equipment.

[0022] In this embodiment, specifically, the vertical beam layer 4 includes at least four beams 3 and the adjacent spacing is not less than 100mm, the horizontal beam 3 layer includes at least four layers and each layer includes two beams 3, the spacing between adjacent horizontal beam 3 layers is not less than 300mm, and the two ends of the busbar 8 correspond to two beams 3 in the horizontal beam 3 layer, respectively, and the spacing is not less than 20mm. The copper bar 13 is placed horizontally and is located between every two adjacent beams 3 in the vertical beam layer 4, and the upper and lower ends of the copper bar 13 are not exposed to the vertical beam 3.

[0023] For the installation of the busbar 8, the present application does not adopt the common common box closed type. In order to further reduce the space occupied by the busbar 8 inside the switch cabinet, the present application first presets a frame structure 2 on the inner wall of the frame, and fixes the busbar clamp 9 to the left side of the frame structure 2, and then adjusts the grouped busbar clamps 9 with the adjusting screw 10 to fix the busbar 8 in a hollow manner. Each layer corresponds to a group of busbar clamps 9 to ensure a firm installation. After the subsequent external air switch module is installed, the overlap is more convenient.

[0024] Similarly, a mounting plate 14 fixed integrally with the inner wall of the cabinet 1 is also vertically fixed to the top of the inner side of the vertical beam layer 4, and the isolating switch 11 is bolted to the mounting plate 14. The front of the cabinet 1 is hinged with an upper door plate 15 and a lower door plate 16 arranged adjacent to each other. The upper door plate 15 is used to seal the vertical beam layer 4, and the lower door plate 16 is used to seal the multiple horizontal beam layers 3. The upper door plate 15 is also provided with a square viewing window 17. The cabinet 1 is blocked and sealed with the upper and lower independent door plates, which makes subsequent inspection more convenient.

[0025] Furthermore, a cable clamp 18 is fixedly connected to the top of the cabinet 1, and a plurality of laterally arranged wire holes 19 are evenly distributed on the cable clamp 18. A group of vents 20 are also opened on the top of the cabinet 1, and hanging rings 21 are fixed at the four corners of the top. The cable clamp 18 is for the convenience of subsequent cable passing, the vents 20 can ensure the heat dissipation inside the switch cabinet, and the hanging rings 21 are for the convenience of subsequent transportation and relocation of engineering equipment.

[0026] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
