[0024] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by the person skilled in the art without creative labor are within the protection scope of the present utility model.
[0025] Please refer to Figure 1 and Figure 2 The utility model discloses a cabinet body structure of switch board, including cabinet body 10 and the outer door 14 of hinged in the front of cabinet body 10, install the side plate 11 in the left and right sides of cabinet body 10 respectively. A plurality of installation port 111 are set up from top to bottom on side plate 11. The installation plate 12 can be detachably installed at every installation port 111. Every installation plate 12 is fixed on side plate 11 through screw. Since switch board generally adopts full enclosed structure, its main purpose is to prevent the invasion of extraneous dust, moisture and other impurities, to guarantee the safe and reliable operation of electrical equipment. Therefore, in the manufacturing process of switch board, the hole for the power supply of equipment is not set in advance. Usually, before the switch board is installed to the power distribution room, according to actual needs, the hole that is adapted to the number and size of the power supply of equipment is accurately set in the field. Then, the switch board is installed to the power distribution room, and the power supply of equipment is contacted and electrically connected with the busbar in the switch board through the circuit breaker. However, when the enterprise needs to increase new equipment, there is no hole for the power line of new equipment to pass through on the switch board. If the hole is directly set in the switch board in the power distribution room to solve this problem, it may cause serious safety hazard. When the power line of new equipment needs to be connected to the switch board, the installation plate at one installation port is detached, then the installation plate 12 is moved to the outside of the power distribution room and the hole that is adapted to the power line of equipment is set, then the installation plate with the hole is installed back to the original place, and the power line of new equipment is connected with the circuit breaker in the switch board through the hole in the installation plate 12, which is very safe and convenient.
[0026] In the embodiment, the mounting plate 12 comprises a plate body 121 and a lower edge connected to the lower edge of the plate body 121. The lower edge of the upper mounting plate 12 is pressed on the upper edge of the adjacent lower mounting plate 12. The lower edge comprises an inclined part 122 connected to the lower edge of the plate body 121 and a vertical part 123 connected to the lower edge of the inclined part 122. A sealing rubber is pasted on the inner side of the lower edge. Since the mounting plate is detachably mounted at the mounting opening, there will be a gap between the mounting plate 12 and the side plate 11. When it is cold and humid, because of the temperature difference between the inside and outside of the cabinet, water vapor in the air will condense on the surface of the cabinet to form water droplets. When the water droplets flow down the side plate, they may seep into the cabinet through the gap between the mounting plate 12 and the side plate 11, causing safety hazards. By using the structure of the mounting plate described above, when there are water droplets flowing down the side plate, the water droplets directly drip onto the bottom surface along the plate body and the lower edge, preventing liquid from seeping into the cabinet. In addition, the upper edge of the uppermost mounting plate and the side plate can be sealed with sealing rubber to prevent water droplets from seeping in between the uppermost mounting plate and the side plate.
[0027] As shown in Figure 3 , a vertical busbar 9 and a plurality of circuit breakers 8 located on both sides of the busbar are installed in the cabinet 10. The conductive plug 801 of the circuit breaker 8 is inserted into the corresponding edge of the busbar. The circuit breaker 8 is installed in the cabinet by a mounting structure.
[0028] As shown in Figure 4 and Figure 5 , in the embodiment, the mounting structure comprises a bracket 21 and a mounting plate 20 located behind the busbar. The bracket 21 is mounted on the back of the circuit breaker 8. The mounting plate 20 is provided with a hole assembly 22. The hole assembly 22 comprises mounting holes 222 arranged at intervals and horizontal slots 221. The bracket 21 has a hook 211 inserted into the slot 221 on the bottom surface and a through hole 212 at the tail end which communicates with the mounting hole 222. Locking screws are arranged in the through hole 212 and the mounting hole 222. Of course, the bracket 21 can be provided in multiple sizes to meet the installation needs of circuit breakers of different sizes.
[0029] The slot 221 has a tapered end that tapers towards the busbar. Additionally, a through hole 213 is provided at the rear of the bracket 21. Auxiliary holes 223 are provided between the slot 221 and the mounting hole 222, corresponding to the through hole 213, to adjust the position of the bracket 21. There are four auxiliary holes 223, spaced apart along the length of the mounting plate. During assembly, the tip of a flathead screwdriver is inserted through the through hole 213 into the auxiliary hole 223, which is biased towards the busbar. Then, using the auxiliary hole 223 as a fulcrum, the screwdriver is used to push the bracket to one side of the busbar, causing the circuit breaker to engage with the busbar. Because the end of the slot is a tapered head with a gradually narrowing width, the end of the bracket clamps the hook during engagement. When the mounting hole 222 aligns with the through hole 212, the end of the locking screw is passed through the through hole 212 and tightened into the mounting hole 222. Multiple auxiliary holes improve the flexibility and accuracy of installation. Removal can also be performed quickly through the auxiliary holes 223.
[0030] In this embodiment, multiple sets of hole assemblies 22 are arranged along the height direction of the mounting plate. This structure allows multiple circuit breakers 8 to be installed at different locations. A vertical row of hole assemblies 22 is symmetrically arranged on both sides of the busbar on the mounting plate. Furthermore, a vertical row of hole assemblies 22 is also provided outside the outer row of hole assemblies on one side, allowing larger circuit breakers to be installed on the outer hole assemblies 22.
[0031] like Figure 1 and Figure 6 As shown, in this embodiment, an inner door 30 is installed inside the cabinet 10, located behind the outer door 14. A window 31 is provided on the inner door 30 for convenient operation of the circuit breaker 8. A recessed frame 32 is connected to the perimeter of the window 31. A busbar cover 34, which encloses the busbar 9, is provided inside the window 31. The busbar cover 34 has multiple ventilation holes. The inner door 30 is divided into an upper door body 301 and a lower door body 302. During normal use, closing the inner door provides protection, preventing injury to operators during maintenance and repair; it can be opened for convenient maintenance. The window design also facilitates the operation of the circuit breaker.
[0032] like Figure 3As shown, the cabinet body 10 is mounted on the ventilated base 102. The ventilated base 102 is communicated with the inside of the cabinet body 10. The first ventilation holes 103 are arranged on the ventilated base 102 and the lower part of the outer door 14. The second ventilation holes 104 are arranged on the upper door body 301 of the inner door 30 and the upper part of the outer door. Since the busbar is heated after working for a period of time, the air temperature in the cabinet body rises, the hot air rises due to small density, is discharged through the second ventilation holes on the top of the cabinet body, and the cold air is continuously supplemented into the cabinet body through the first ventilation holes below, so that the cabinet body forms a natural ventilation circulation, thereby achieving the purpose of heat dissipation.
[0033] In summary, the installation plate is detachably installed at each mounting port of the side plate, so that the installation plate can be taken out of the power distribution room to form a hole for the equipment power line to pass through, thereby facilitating the electrical connection of the equipment power line with the circuit breaker and the busbar. Secondly, the circuit breaker is installed on the bracket, the hook head of the bracket is inserted into the horizontal hole, and the bracket is quickly installed in place by cooperating the vertical hole with the perforation, so that the circuit breaker is installed in place. Furthermore, the inner door is installed in the cabinet body, the inner door is closed during normal use to play a protective role, so as to avoid the injury of the operator during maintenance and repair; the inner door can be opened during repair to facilitate repair. The window setting also facilitates the operation of the circuit breaker by the operator.
[0034] The above describes one embodiment of the utility model in detail, but the content described can only be the preferred embodiment of the utility model, and cannot be considered as limiting the implementation range of the utility model. Any equivalent change and improvement within the scope of the utility model application should still belong to the patent coverage range of the utility model.
