Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified.

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

[0048] The cabinet body 3 is used for cabinet connection with other cabinets, the electrical cabinet body 1 is located in the cabinet body 3 and is electrically connected with other cabinets to form a cabinet system. It can be understood that the cabinet system comprises a plurality of cabinet bodies 3, the plurality of cabinet bodies 3 are arranged in rows, and the height and the length in the front-rear direction of the plurality of cabinet bodies 3 are equal. The cabinet body 3 as a modular cabinet body can improve the overall appearance of the cabinet system. The plurality of cabinet bodies 3 can be electrically connected, or some of the plurality of cabinet bodies 3 can be electrically connected. The electrical connection mode of the cabinet body 3 is determined according to the specific application requirements of the cabinet system.

[0049] Each cabinet body 3 can place an electrical cabinet body 1. It should be noted that the functions of each electrical cabinet body 1 can be different, such as some electrical cabinet bodies 1 are UPS cabinets, some electrical cabinet bodies 1 are power distribution cabinets, some electrical cabinet bodies 1 are bus tie cabinets, etc. The electrical cabinet body 1 is electrically connected with other cabinets to realize power-on. The electrical cabinet body 1 can be electrically connected with its corresponding cabinet body 3, or can not be electrically connected. As long as the electrical cabinet body 1 can be electrically connected with at least one other electrical cabinet body 1 to realize overall power-on of the cabinet system.

[0050] It should be noted that not every parallel cabinet body 3 must be placed with the electrical cabinet body 1. For the electrical module which does not need to be maintained and replaced frequently, the electrical module can be directly placed in the parallel cabinet body 3. For the electrical module which needs to be maintained or replaced frequently, or the multiple electrical modules which need to be integrated, the electrical module can be integrated in the electrical cabinet body 1, and then the electrical cabinet body 1 is placed in the parallel cabinet body 3. Therefore, the parallel cabinet body 3 and the electrical cabinet body 1 can be understood as the shell structure with a cavity, and the shell structure of the electrical cabinet body 1 is smaller than that of the parallel cabinet body 3. In addition, the shell structure of the parallel cabinet body 3 and the shell structure of the electrical cabinet body 1 are respectively provided with a front door plate, and the front door plate can be opened relative to the shell structure.

[0051] In the above multiple electrical cabinet bodies 1, the inside of at least one electrical cabinet body 1 is provided with a maintainable cabinet body 2. The maintainable cabinet body 2 is part of the electrical cabinet body 1 and realizes the main function of the electrical cabinet body 1. The service life of the maintainable cabinet body 2 is short, and it needs to be maintained and replaced regularly. Therefore, the maintainable cabinet body 2 can be pulled out to the outside of the electrical cabinet body 1. The maintainable cabinet body 2 is electrically connected with the electrical cabinet body 1, and is powered by the electrical cabinet body 1.

[0052] It should be noted that the above electrical connection includes strong current line connection and weak current line connection.

[0053] Specifically, when the maintainable cabinet body 2 needs to be maintained or replaced, the maintainable cabinet body 2 is disconnected with the electrical cabinet body 1, so that the maintainable cabinet body 2 is not electrified and is in a non-working state. Then, the maintainable cabinet body 2 is moved and pulled out to the outside of the electrical cabinet body 1, and subsequent maintenance or replacement operation is performed. Since the maintainable cabinet body 2 is independently arranged in the electrical cabinet body 1, and there is no direct connection relationship in position between the maintainable cabinet body 2 and other electrical cabinet bodies 1 or the parallel cabinet body 3, the moving operation is facilitated.

[0054] Compared with the prior art, the cabinet provided by the present application is that the parallel cabinet body 3 is used to be parallel with other cabinets, the electrical cabinet body 1 is located in the parallel cabinet body 3 and is electrically connected with other cabinets to form a cabinet system, the maintainable cabinet body 2 is located in the electrical cabinet body 1 and can be pulled out to the outside of the electrical cabinet body 1. When the maintainable cabinet body 2 needs to be maintained or replaced, the maintainable cabinet body 2 only needs to be in a non-working state and be pulled out from the electrical cabinet body 1, without moving the electrical cabinet body 1 and the parallel cabinet body 3, so that the overall maintenance efficiency and replacement efficiency of the cabinet and the cabinet system are improved.

[0055] In some embodiments, the above electrical cabinet body 1 can adopt the structure as shown in Figure 2 , Figure 3 and Figure 4 , and the specific structure is shown in Figure 2 , Figure 3 and Figure 4The inner cavity of the electrical cabinet body 1 is divided into a power distribution chamber 12 and an electrical chamber 11; the power distribution chamber 12 is provided with power distribution devices; the maintainable cabinet body 2 is located in the electrical chamber 11 and is electrically connected with the power distribution devices; and the power distribution devices are used to control the on-off of the maintainable cabinet body 2.

[0056] The inner cavity of the electrical cabinet body 1 can be provided with a vertical frame 13, which is used to divide the inner cavity of the electrical cabinet body 1 into the power distribution chamber 12 and the electrical chamber 11; of course, no separation structure can be provided, and the inner cavity of the electrical cabinet body 1 is only separated by the maintainable cabinet body 2 in space.

[0057] The maintainable cabinet body 2 is located in the electrical chamber 11 and can be pulled out from the electrical chamber 11. Since the service life of the power distribution devices is long and they do not need to be maintained regularly, in order to reduce the interference of the external environment on the power distribution devices, the power distribution chamber 12 and the electrical chamber 11 are independently provided with front door plates and back plates; when maintenance or replacement is performed, only the front door plate and / or the back plate of the electrical chamber 11 needs to be opened, and the front door plate and the back plate of the power distribution chamber 12 do not need to be opened.

[0058] It should be noted that in the embodiment, the maintainable cabinet body 2 is only electrically connected with the power distribution devices and is controlled by the power distribution devices to be on or off. The maintainable cabinet body 2 is not electrically connected with other electrical cabinet bodies 1 or parallel cabinet bodies 3, but is indirectly electrically connected with other electrical cabinet bodies 1 or parallel cabinet bodies 3 through the power distribution devices to be in a working state.

[0059] The power distribution devices can be provided with independent switches, which are used to control the on-off of the power distribution devices and the cabinet system. After the independent switches are turned off, the power distribution devices are in a power-off state, and the maintainable cabinet body 2 is also in a non-working state without electricity. Then, the connection between the power distribution devices and the maintainable cabinet body 2 is disconnected, so that the maintainable cabinet body 2 can be pulled out from the electrical cabinet body 1 for subsequent maintenance or replacement.

[0060] The power distribution devices are provided for the maintainable cabinet body 2, and the power distribution devices and the maintainable cabinet body 2 are located in the same electrical cabinet body 1. By turning off the power distribution devices, the maintainable cabinet body 2 can be turned off, so that the entire cabinet system does not need to be turned off, and the normal work of other electrical cabinet bodies 1 is not 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 body 1 can adopt the structures shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , and the structures are shown in Figure 2 , Figure 3 , Figure 4 and Figure 5The power distribution chamber 12 and the electrical chamber 11 are arranged in the left-right direction; the maintainable cabinet 2 has an avoiding space 23, and the avoiding space 23 is communicated with the electrical chamber 11 and the power distribution chamber 12; the maintainable cabinet 2 is electrically connected with the power distribution device through the copper bar assembly 4; and the copper bar assembly 4 is located in the avoiding space 23.

[0062] Since the parallel cabinet cabinet 3 is generally parallel with other cabinets in the left-right direction, that is, the left and right sides of the parallel cabinet cabinet 3 are blocked by other cabinets, and it is inconvenient to operate manually in the left-right direction, and can only be operated from the front and / or rear of the parallel cabinet cabinet 3, therefore, in order to adapt to the parallel direction of the parallel cabinet cabinet 3, the power distribution chamber 12 and the electrical chamber 11 are also arranged in the left-right direction, and then the copper bar assembly 4 connecting the power distribution device and the maintainable cabinet 2 can be extended and arranged in the left-right direction, and the copper bar assembly 4 will not be blocked by the power distribution device and the maintainable cabinet 2 in the front-rear direction, thereby facilitating the disconnection and connection operation of the copper bar assembly 4 from the front and / or rear of the parallel cabinet cabinet 3.
