They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0047] Please see Figure 1 The cabinet provided by the present invention will now be described. The cabinet includes a parallel cabinet 3, an electrical cabinet 1, and a maintainable cabinet 2. The parallel cabinet 3 is used for paralleling with other cabinets; the electrical cabinet 1 is located inside the parallel cabinet 3 and is used for electrical connection with other cabinets; the maintainable cabinet 2 is located inside the electrical cabinet 1 and can be moved and pulled out to the outside of the electrical cabinet 1; the maintainable cabinet 2 is also electrically connected to the electrical cabinet 1. The maintainable cabinet 2 has a working state and a non-working state. In the working state, the maintainable cabinet 2 is fixed inside the electrical cabinet 1 and is powered on; in the non-working state, the maintainable cabinet 2 is de-powered and can be pulled out to the outside of the electrical cabinet 1.

[0048] The cabinet 3 is used for merging with other cabinets. The electrical cabinet 1 is located inside the cabinet 3 and is electrically connected to the other cabinets to form a cabinet system. This system can be understood as consisting of multiple cabinets 3 arranged in a row, with all cabinets 3 having the same height and length in both the front and rear directions. As modular cabinets, the cabinet 3 enhances the overall aesthetics of the cabinet system. Multiple cabinets 3 can be electrically connected to each other, or only a few cabinets 3 can be electrically connected; the method of electrical connection depends on the specific application requirements of the cabinet system.

[0049] Each cabinet 3 can house an electrical cabinet 1. It should be noted that the functions of each electrical cabinet 1 can differ; for example, some electrical cabinets 1 may be UPS cabinets, some may be power distribution cabinets, some may be bus tie cabinets, and so on. Electrical cabinets 1 are electrically connected to other cabinets to enable power supply. Electrical cabinets 1 may or may not be electrically connected to their corresponding cabinet 3. As long as electrical cabinet 1 can be electrically connected to at least one other electrical cabinet 1, the entire cabinet system can be powered on.

[0050] It should be noted that not every cabinet 3 needs to contain an electrical cabinet 1. Electrical modules that do not require frequent maintenance or replacement can be placed directly inside cabinet 3. For electrical modules that require frequent maintenance or replacement, or for multiple electrical modules that need to be integrated, the modules can be integrated into electrical cabinet 1, which is then placed inside cabinet 3. Therefore, cabinet 3 and electrical cabinet 1 can be understood as shell structures with cavities, except that the shell structure of electrical cabinet 1 is smaller than that of cabinet 3. Furthermore, both the shell structures of cabinet 3 and electrical cabinet 1 have front panels that can be opened relative to the shell structure.

[0051] In the aforementioned plurality of electrical cabinets 1, at least one electrical cabinet 1 has a maintainable cabinet 2 inside. The maintainable cabinet 2 is an integral part of the electrical cabinet 1 and performs the main functions of the electrical cabinet 1. The maintainable cabinet 2 has a short service life and requires regular maintenance and replacement; therefore, the maintainable cabinet 2 can be pulled out to the outside of the electrical cabinet 1. The maintainable cabinet 2 is electrically connected to the electrical cabinet 1 and is powered by the electrical cabinet 1.

[0052] It should be noted that the above electrical connections include both high-voltage and low-voltage line connections.

[0053] Specifically, when maintenance or replacement of the maintainable cabinet 2 is required, the power to the maintainable cabinet 2 and the electrical cabinet 1 is disconnected, so that the maintainable cabinet 2 is de-energized and in a non-working state. Then, the maintainable cabinet 2 is moved and pulled out to the outside of the electrical cabinet 1 for subsequent maintenance or replacement operations. Since the maintainable cabinet 2 is independently installed inside the electrical cabinet 1 and has no direct positional connection with other electrical cabinets 1 or parallel cabinets 3, it is convenient to move it.

[0054] Compared with the prior art, the cabinet provided by the present invention has a parallel cabinet 3 for paralleling with other cabinets, an electrical cabinet 1 located inside the parallel cabinet 3 and electrically connected to other cabinets to form a cabinet system; a maintainable cabinet 2 located inside the electrical cabinet 1 and can be pulled out of the electrical cabinet 1. When maintenance or replacement of the maintainable cabinet 2 is required, it is only necessary to put the maintainable cabinet 2 in a non-working state and pull it out of the electrical cabinet 1, without moving the electrical cabinet 1 and the parallel cabinet 3, thereby improving the overall maintenance and replacement efficiency of the cabinet and the cabinet system.

[0055] In some embodiments, the electrical cabinet 1 described above may adopt the following... Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4The internal cavity of the electrical cabinet 1 is divided into a power distribution chamber 12 and an electrical chamber 11. The power distribution chamber 12 is equipped with power distribution devices. The maintainable cabinet 2 is located in the electrical chamber 11 and is electrically connected to the power distribution devices. The power distribution devices are used to control the power supply to and from the maintainable cabinet 2.

[0056] The inner cavity of the electrical cabinet 1 can be provided with a vertical frame 13, which can be used to divide the inner cavity of the electrical cabinet 1 into a power distribution chamber 12 and an electrical chamber 11; of course, no partition structure can be provided, and the inner cavity of the electrical cabinet 1 can be spatially divided by the maintainable cabinet 2.

[0057] The maintainable cabinet 2 is located inside the electrical chamber 11 and can be pulled out from the electrical chamber 11. Since the power distribution components have a long service life and do not require regular maintenance, in order to reduce the interference of the external environment on the power distribution components, the power distribution chamber 12 and the electrical chamber 11 are each equipped with independent front and rear panels; when performing maintenance or replacement operations, only the front and / or rear panels of the electrical chamber 11 need to be opened, without opening the front and rear panels of the power distribution chamber 12.

[0058] It should be noted that in this embodiment, the maintainable cabinet 2 is only electrically connected to the power distribution device, which controls the power supply to and from the maintainable cabinet 2. The maintainable cabinet 2 is not electrically connected to other electrical cabinets 1 or parallel cabinets 3, but is indirectly electrically connected to other electrical cabinets 1 or parallel cabinets 3 through the power distribution device to be in working condition.

[0059] The power distribution device can be equipped with an independent switch, which is used to control the power supply between the power distribution device and the cabinet system. After the independent switch is turned off, the power distribution device is in a de-energized state, and the maintainable cabinet 2 is also in a non-operating state without power. Then, disconnect the connection between the power distribution device and the maintainable cabinet 2, and the maintainable cabinet 2 can be pulled out from the electrical cabinet 1 for subsequent maintenance or replacement operations.

[0060] The maintainable cabinet 2 is equipped with a power distribution device, and both the power distribution device and the maintainable cabinet 2 are located in the same electrical cabinet 1. By de-energizing the power distribution device, the maintainable cabinet 2 can be de-energized. Therefore, it is not necessary to de-energize the entire cabinet system, and the normal operation of other electrical cabinets 1 will not be affected, thereby improving the maintenance and replacement efficiency of the cabinet and the entire cabinet system.

[0061] In some embodiments, the inner cavity of the electrical cabinet 1 can be made as follows: Figure 2 , Figure 3 , Figure 4 and Figure 5 The structure shown is described in the following document. Figure 2 , Figure 3 , Figure 4 and Figure 5The power distribution chamber 12 and the electrical chamber 11 are arranged in a left-right direction; the maintainable cabinet 2 has a clearance space 23 inside, and the clearance space 23 is connected to the electrical chamber 11 and the power distribution chamber 12; the maintainable cabinet 2 is electrically connected to the power distribution devices through the copper busbar assembly 4; the copper busbar assembly 4 is located in the clearance space 23.

[0062] Since the cabinet 3 is generally connected to other cabinets in the left-right direction, other cabinets will block the left and right sides of the cabinet 3, making it inconvenient to operate manually in the left-right direction. Operation can only be performed from the front and / or rear of the cabinet 3. Therefore, in order to adapt to the cabinet 3's connection direction, the power distribution chamber 12 and the electrical chamber 11 are also arranged in the left-right direction. Thus, the copper busbar assembly 4 connecting the power distribution device and the maintainable cabinet 2 can also extend in the left-right direction. In the front-back direction, the copper busbar assembly 4 will not be blocked by the power distribution device and the maintainable cabinet 2, thereby facilitating manual disconnection and connection operations of the copper busbar assembly 4 from the front and / or rear of the cabinet 3.

[0063] In addition, a clearance space 23 is provided in the maintainable cabinet 2 to avoid the copper busbar assembly 4. The disconnection and connection operations of the copper busbar assembly 4 are all carried out in the clearance space 23. The clearance space 23 provides both installation space and operation space for the copper busbar assembly 4, further facilitating the disconnection and connection operations of the copper busbar assembly 4.

[0064] The power distribution components are connected to the maintainable cabinet 2 via copper busbar assembly 4. Compared to the method of connecting via wires, the copper busbar assembly 4 is distributed in a regular manner and will not shake randomly. It does not require additional wire clamps for fixation, and it is easy for people to disconnect the copper busbar assembly 4.

[0065] Specifically, when the power distribution device is turned on, that is, when the independent switch of the power distribution device is turned on, the copper busbar assembly 4 is connected to the maintainable cabinet 2, and the maintainable cabinet 2 is in the working state; when the power distribution device is turned off, that is, when the independent switch of the power distribution device is turned off, the copper busbar assembly 4 can be disconnected from the maintainable cabinet 2, and the maintainable cabinet 2 is in the non-working state.

[0066] Specifically, the copper busbar assembly 4 is always connected to the power distribution device, which supplies power to the maintainable cabinet 2 through the copper busbar assembly 4. When the independent switch of the power distribution device is turned off, the power distribution device is disconnected from the entire mechanism system. At this time, the entire electrical cabinet 1 is de-energized. Then, the copper busbar assembly 4 is disconnected from the maintainable cabinet 2, and the maintainable cabinet 2 can be pulled out to the outside of the electrical cabinet 1.

[0067] In some embodiments, the copper busbar assembly 4 includes a first copper busbar group 41 connected to the power distribution device and a second copper busbar group 42 connected to the maintainable cabinet 2; the first copper busbar group 41 extends in the left-right direction, and one end of the first copper busbar group 41 is connected to the power distribution device, and the other end extends into the clearance space 23; the second copper busbar group 42 is disposed at the rear of the maintainable cabinet 2, and one end of the second copper busbar group 42 is connected to the maintainable cabinet 2, and the other end extends into the clearance space 23 and is connected to the other end of the second copper busbar group 42.

[0068] In this embodiment, the electrical connection between the power distribution device and the maintainable cabinet 2 is achieved through the first copper busbar group 41 and the second copper busbar group 42. Compared with the wire connection method, the connection method of the two copper busbar groups is more stable and reliable, easy to disassemble, and will not interfere with other electronic components to cause short circuits.

[0069] The connection between the first copper busbar group 41 and the second copper busbar group 42 is located in the clearance space 23. The connection and disconnection operations of the first copper busbar group 41 and the second copper busbar group 42 are all carried out in the clearance space 23. There are no other components in the clearance space 23 except for the first copper busbar group 41 and the second copper busbar group 42, so it does not affect the operation.

[0070] Specifically, the first copper busbar group 41 includes multiple first copper busbars, the other ends of which are all located within the clearance space 23, and the multiple first copper busbars are spaced apart in the front-back direction; the second copper busbar group 42 includes multiple second copper busbars that are connected to the multiple first copper busbars one-to-one. Preferably, the second copper busbars are connected to the corresponding first copper busbars by bolts.

[0071] In addition, the internal cavity of the electrical cabinet 1 is provided with a vertical frame 13, which divides the internal cavity of the electrical cabinet 1 into a power distribution chamber 12 and an electrical chamber 11; the vertical frame 13 is also provided with a supporting longitudinal beam 131, and multiple first copper busbars are placed on the supporting longitudinal beam 131, such as Figure 3 As shown.

[0072] Specifically, after the independent switch of the power distribution device is turned off, the electrical cabinet 1 is de-energized, the copper busbar assembly 4 is not energized, and the connecting bolts between the second copper busbar and the corresponding first copper busbar are removed manually from front to back or from back to front. After the second copper busbar assembly 42 is completely disconnected from the first copper busbar assembly 42, the maintainable cabinet 2 can be moved and pulled out.

[0073] In some embodiments, the electrical cabinet 1 can be moved out to the outside of the cabinet 3. That is, the electrical cabinet 1 is not completely fixed inside the cabinet 3. When the electrical cabinet 1 needs to be replaced or maintained, the entire cabinet system needs to be powered off first. After the electrical cabinet 1 is de-energized, it can be moved out to the outside of the cabinet 3.

[0074] In some embodiments, the maintainable cabinet 2 described above can be adopted as follows: Figure 5 and Figure 6 The structure shown is described in the following document. Figure 5 and Figure 6 The maintainable cabinet 2 includes a support frame 21 and multiple electrical modules 22. The support frame 21 is movably installed inside the electrical cabinet 1; the multiple electrical modules 22 are spaced apart on the support frame 21 in the vertical direction, and each electrical module 22 can slide on the support frame 21 in the front-back direction; wherein, the two electrical modules 22 located in the middle are separated by a clearance space 23.

[0075] The support frame 21 is a hexahedral frame, with multiple support beams on its left and right sides, where two horizontally corresponding support beams form a group. Each electrical module 22 rests on a group of support beams on its bottom left and right sides and can slide back and forth relative to the support beams. Each electrical module 22 can be independently removed from the support frame 21, facilitating the maintenance and replacement of individual electrical modules 22.

[0076] In some embodiments, the maintainable cabinet 2 and the electrical cabinet 1 may also be connected by, for example, Figure 2 , Figure 3 and Figure 4 The structure shown is described in the following document. Figure 2 , Figure 3 and Figure 4 The electrical cabinet 1 is detachably connected to a fixing beam 14. When the maintainable cabinet 2 is located inside the electrical cabinet 1, the fixing beam 14 is also connected to the maintainable cabinet 2.

[0077] Specifically, multiple fixing beams 14 are provided, which can be connected to the top, bottom, and back surfaces of the maintainable cabinet 2 (mainly the support frame 21) respectively. Before maintaining or replacing the maintainable cabinet 2, the connection between the fixing beams 14 and the maintainable cabinet 2 needs to be disconnected first, and then the maintainable cabinet 2 can be pulled out of the electrical cabinet 1. After the maintainable cabinet 2 is maintained or replaced, the maintainable cabinet 2 is reinstalled into the electrical cabinet 1, and the multiple fixing beams 14 are connected to the maintainable cabinet 2 and the electrical cabinet 1 in sequence to increase the stability of the maintainable cabinet 2.

[0078] In some embodiments, the maintainable cabinet 2 and the electrical cabinet 1 may also be connected by, for example, Figure 4 The structure shown is described in the following document. Figure 4 The bottom surface of the maintainable cabinet 2 is connected to rollers; and / or, the bottom surface of the electrical cabinet 1 is provided with a rolling support structure 16, which makes rolling contact with the bottom outer periphery of the maintainable cabinet 2.

[0079] Rollers are installed on the bottom surface of the maintainable cabinet 2. The maintainable cabinet 2 is moved by the rollers. By pushing the maintainable cabinet 2, it can be moved easily, thereby improving the ease of movement of the maintainable cabinet 2 within the electrical cabinet 1.

[0080] In addition to the rollers, a rolling support structure 16 can be installed on the bottom surface of the electrical cabinet 1. Each rolling support structure 16 can rotate around its own axis, and each rolling support structure 16 contacts the bottom surface of the maintainable cabinet 2. When the maintainable cabinet 2 is pushed, each rolling support structure 16 rolls and rubs against the maintainable cabinet 2, thereby improving the ease of movement of the maintainable cabinet 2 within the electrical cabinet 1.

[0081] The rolling support structure 16 can be a rotating frustum, rotating in the up-down direction. The outer circumferential surface of the rotating frustum is in rolling contact with the bottom outer circumferential surface of the maintainable cabinet 2.

[0082] In some embodiments, the maintainable cabinet 2 and the electrical cabinet 1 may also be connected by, for example, Figure 6 and Figure 7 The structure shown is described in the following document. Figure 6 and Figure 7 The electrical cabinet 1 has a stop 15 inside, and the maintainable cabinet 2 has a positioning part 24. The positioning part 24 is used to engage with the stop 15 to limit the fixed position of the maintainable cabinet 2 inside the electrical cabinet 1.

[0083] Preferably, the positioning part 24 is disposed on the rear end face of the support frame 21, and the positioning part 24 is a block structure; the stop part 15 is disposed on the rear inner wall of the electrical cabinet 1, and the stop part 15 is provided with a positioning hole that engages with the positioning part 24. The positioning hole and the positioning part 24 correspond to each other in the front-rear direction. During the process of pushing the maintainable cabinet 2 backward, when the positioning part 24 is inserted into the positioning hole, it indicates that the maintainable cabinet 2 is installed in place. If the positioning part 24 is not inserted into the positioning hole, it indicates that the maintainable cabinet 2 cannot be pushed in place, and the position of the maintainable cabinet 2 needs to be adjusted until the positioning part 24 is inserted into the positioning hole.

[0084] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
