[0002] High-voltage switchgear is an important piece of equipment used for power distribution and protection in power systems. It is widely used in industrial, commercial and civil buildings. Split-type high-voltage switchgear is designed as two detachable upper and lower cabinets. During installation, the sides of the upper cabinet and the lower cabinet are connected by bolts.

[0003] However, this simple bolt connection is not strong enough and is prone to loosening or falling off, affecting the stability and safety of the equipment. Moreover, due to the split design, the connection parts of the split high-voltage switchgear lack effective reinforcement measures, resulting in insufficient rigidity and stability of the overall structure, making it difficult to withstand large external impacts, and even causing deformation and other problems. Summary of the Invention

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] The split-type high-voltage switchgear of this utility model is described below with reference to the accompanying drawings.

[0029] like Figure 1 and Figure 2 As shown, the split-type high-voltage switchgear of this utility model embodiment may include a lower cabinet 100, an upper cabinet 200, and a reinforcing device 300.

[0030] The upper cabinet 200, the reinforcing device 300, and the lower cabinet 100 are arranged sequentially from top to bottom. The upper cabinet 200 and the lower cabinet 100 have openings on their opposite sides, and the openings of the upper cabinet 200 and the lower cabinet 100 are embedded in the upper and lower ends of the reinforcing device 300.

[0031] It should be noted that both the upper cabinet 200 and the lower cabinet 100 are equipped with mounting brackets to facilitate the installation of corresponding components, and both the upper cabinet 200 and the lower cabinet 100 are provided with wire-passing holes to facilitate wire threading.

[0032] like Figure 4 and Figure 5 As shown, insertion slots 101 are provided at the corners of the inner walls of both the upper cabinet 200 and the lower cabinet 100.

[0033] It should be noted that the slot of the plug groove 101 on the upper cabinet 200 extends downward from the top, and the slot of the plug groove 101 on the lower cabinet 100 extends upward from the bottom. Furthermore, the setting of the plug groove 101 itself can improve the side strength of the corresponding upper cabinet 200 and lower cabinet 100.

[0034] like Figure 3 , Figure 6 to Figure 8 As shown, the reinforcing device 300 includes a connecting ring 310 and a right-angle insertion post 320.

[0035] The connecting ring 310 has slots 311 at both the top and bottom ends. The upper cabinet 200 and the lower cabinet 100 are respectively engaged in the corresponding slots 311 and locked with bolts. Right-angle insertion posts 320 are provided at the four corners of the upper and lower ends of the connecting ring 310. The right-angle insertion posts 320 at the upper and lower ends of the connecting ring 310 are respectively inserted into the corresponding insertion slots 101.

[0036] It should be noted that the right-angle plug 320 matches the slot of the plug groove 101.

[0037] Specifically, when relevant personnel install the split-type high-voltage switchgear of this utility model, firstly, the lower cabinet 100 is fixed in the installation position, and then the reinforcing device 300 is installed on the lower cabinet 100, that is, the slot 311 at the lower end of the connecting ring 310 is engaged with the top opening of the lower cabinet 100. At the same time, the right-angle insertion post 320 at the lower end of the connecting ring 310 is inserted into the insertion slot 101 of the lower cabinet 100, and the connecting ring 310 and the lower cabinet 100 are locked together by bolts.

[0038] Then, the relevant staff installed the upper cabinet 200 on the reinforcing device, that is, the opening at the lower end of the upper cabinet 200 was snapped into the slot 311 at the upper end of the connecting ring sleeve 310. At the same time, the insertion slot 101 of the upper cabinet 200 was inserted and connected to the right-angle insertion post 320 at the upper end of the connecting ring sleeve 310. The relevant staff then tightened the connecting ring sleeve 310 and the upper cabinet 200 with bolts.

[0039] It should be noted that mounting holes 312 are provided at the upper cabinet 200, the lower cabinet 100 and the slot 311. Bolts are passed through the mounting holes 312 to lock the upper cabinet 200 or the lower cabinet 100.

[0040] As a possible scenario, reinforcing ribs 313 are provided at the four corners of the inner ring of the connecting ring sleeve 310, and the reinforcing ribs 313 are located between the mounting holes 312 at the upper and lower ends of the connecting ring sleeve 310.

[0041] It should be noted that the reinforcing rib 313 can improve the strength of the connecting ring sleeve 310, thereby making the connection between the upper cabinet 200 and the lower cabinet 100 and the connecting ring sleeve 310 stronger and preventing deformation.

[0042] In one embodiment of this utility model, the right-angle plug 320 is an angle steel structure, the groove of the plug groove 101 is a right-angle groove, and the right-angle plug 320 is plugged into the groove of the corresponding plug groove 101.

[0043] To further improve the connection strength between the right-angle plug 320 and the corresponding plug slot 101, the right-angle plug 320 is inserted into the corresponding plug slot 101 and locked with bolts.

[0044] In one embodiment of this utility model, both the lower cabinet 100 and the upper cabinet 200 are provided with openable and closable cabinet doors 102. The cabinet doors 102 are connected to the cabinets by latches. Relevant personnel can open the cabinet doors 102 of the upper cabinet 200 or the lower cabinet 100 according to the electrical components installed in different locations.

[0045] In addition, ventilation openings 103 are provided on the sides of both the lower cabinet 100 and the upper cabinet 200 to improve the overall ventilation effect and prevent the wiring from aging due to excessive temperature inside the cabinet.

[0046] In one embodiment of this utility model, support columns 104 are provided at the four corners of the bottom of the lower cabinet 100.

[0047] As a possible scenario, the support column 104 can be placed directly at the installation location, facilitating subsequent movement of the entire device.

[0048] As another possible scenario, when installing the split-type high-voltage switchgear of this utility model, the installation position is constructed by pouring concrete. After the concrete solidifies, the support column 104 is inserted into the reserved hole in the concrete to improve the convenience and stability of the entire device installation.

[0049] In summary, the split-type high-voltage switchgear according to this utility model embodiment enhances the strength and stability of the connection by setting a reinforcing device 300 between the upper cabinet 200 and the lower cabinet 100. The upper and lower ends of the connecting ring sleeve 310 are provided with slots 311, and the upper cabinet 200 and the lower cabinet 100 are respectively engaged in the corresponding slots 311 and locked with bolts to ensure the firmness of the connection. The right-angle insertion post 320 on the connecting ring sleeve 310 is inserted into the corresponding insertion slot 101, which improves the overall connectivity and overall strength of the upper cabinet 200 and the lower cabinet 100 and can effectively avoid deformation caused by impact.
