[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on July 27, 2023, with application number 202322001911.3 and application name "A Uninterruptible Power Supply Cabinet", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of power supply technology, and in particular to an uninterruptible power supply cabinet. Background Art

[0004] An uninterruptible power supply (UPS) system is a power supply device used to provide power to a load. The UPS input connects to the main power source, while the output connects to the load. Under normal circumstances, the load is powered by the main power source. In the event of a main power failure, the UPS system uses a battery as a backup to provide power to the load, ensuring continuous and uninterrupted power supply.

[0005] Currently, the basic structure of an uninterruptible power supply system can be integrated into a cabinet. However, some components of existing uninterruptible power supply systems are integrated with the cabinet. When these components fail and require replacement or maintenance, the cabinet must be removed for operation, making maintenance difficult. In some scenarios where the cabinet cannot be removed, maintenance on these components is virtually impossible.

[0006] Summary of the Invention

[0008] In a first aspect, an uninterruptible power supply cabinet is provided, which can be used in indoor locations such as data centers to convert power supply into stable and reliable power output. The uninterruptible power supply cabinet includes a cabinet body, a switch assembly, and a power cabinet. The cabinet body has a storage cavity that can be used to accommodate the power cabinet and the switch assembly. The cabinet body is provided with an external port and a first power connection end, and the external port is used to connect external devices such as a power supply and a load.

[0009] The uninterruptible power supply cabinet provided by the present application is detachable between the power cabinet and the cabinet body, and the second power connection end and the first power connection end can form an electrical connection breakpoint between the power cabinet and the cabinet body.

[0077] Figure 1 shows a schematic diagram of the circuit principle of an uninterruptible power supply (UPS) system. As shown in Figure 1, the UPS system is a power supply device. Its input side connects to the power supply through a main switch, converting the power supply into a stable and reliable output. The output side of the UPS connects to the load through an output switch. If the main power supply fails, the UPS uses the battery as backup power and converts it into output power, providing continuous and uninterrupted power to the load. The UPS system includes a control module, a power module, and a bypass module, along with circuit components connected to these modules. If the main power module fails, power is supplied from the bypass input through the bypass switch, then through the bypass module and the output switch to the load. The control module coordinates and controls these switching operations. When maintenance is required on the power module or bypass module, the maintenance bypass switch can be closed. The main switch, bypass switch, output switch, and maintenance bypass switch can be built into the UPS system or externally located in a power distribution cabinet. When an uninterruptible power supply system fails, it is generally necessary to disconnect all external switches and then drag out the cabinet for replacement or maintenance. This maintenance time is long, and in scenarios where the cabinet cannot be dragged out, maintenance is even more difficult.

[0078] Based on this, the embodiments of the present application provide an uninterruptible power supply cabinet, a power supply system, and a data center, wherein the functional modules in the uninterruptible power supply cabinet can realize the replaceability of the functional modules and the replaceability of the power distribution components, thereby improving maintenance convenience and system reliability.

[0079] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0080] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of this application, the singular expressions "a", "an", "said", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0081] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0082] Figure 2 shows that the uninterruptible power supply cabinet 10 provided in an embodiment of the present application includes a cabinet body 1 and a power module 21, a bypass module 31 and a control module 41. The cabinet body 1 includes a main body 11 and a cabinet door 12. The main body 11 has a accommodating cavity R. The power module 21, the bypass module 31 and the control module 41 can be accommodated in the accommodating cavity R. The power module 21 can convert the input AC or DC power into a stable sinusoidal voltage output. When the main circuit is abnormal, the system will switch to the bypass module 31 to supply power to the load. The control module 41 is used to perform system signal acquisition and control of the uninterruptible power supply cabinet 10. The cabinet door 12 is rotatably mounted at the opening of the accommodating cavity R of the main body 11. The cabinet door 12 can be rotated to open or close the accommodating cavity R of the main body 11. Figure 2 shows the state where the cabinet door 12 is open. Of course, the uninterruptible power supply cabinet 10 also includes some lightning protection modules, communication modules or other integrated modules. These modules as well as the power module 21, bypass module 31, and control module 41 have hot-swappable replacement functions and can be directly disassembled, replaced or repaired during maintenance.

[0083] The aforementioned modules, such as the power module 21, bypass module 31, and control module 41, are pluggable and easy to replace or repair. To further reduce system maintenance, some power distribution components within the uninterruptible power supply cabinet 10 in the embodiment of the present application are configured as replaceable units. Specifically, please refer to the schematic diagram of the uninterruptible power supply cabinet 10 shown in FIG3 a. As shown in FIG3 a, the uninterruptible power supply cabinet 10 includes an external port 101 and a first power connection terminal g1, disposed on the main body 11 of the cabinet 1. The external port 101 is illustratively located above the main body 11 and is used to connect to external power supplies, loads, and other devices. Within the cabinet 1 are located a power cabinet 2 and a switch assembly 51, illustratively located above the power cabinet 2. The switch assembly 51 is an integrated circuit comprising multiple isolating switches. An isolating switch is a mechanical switch that meets specified isolation requirements when in the off state. An isolating switch can connect and carry current under normal circuit conditions and, under abnormal circuit conditions such as a short circuit, can carry current for a specified period of time. One end of the switch assembly 51 is electrically connected to the external port 101 , and the other end of the switch assembly 51 is connected to the first power connection end g1 . Specifically, the switch assembly 51 and the first power connection end g1 can be connected via a copper busbar assembly 7 .

[0084] The power cabinet 2 includes a first frame 22 and at least one power module 21. Here, there are five power modules 21, which are stacked in sequence along the height direction of the cabinet body 1. Each power module 21 is detachably mounted on the first frame 22, so that the power module 21 can be detached relative to the first frame 22 to facilitate replacement and maintenance. The first frame 22 includes a second power connection terminal g2, and each power module 21 is detachably electrically connected to the second power connection terminal g2. When the power module 21 is mounted on the first frame 22 and is in the installation position, the power module 21 is electrically connected to the second power connection terminal g2. When the power module 21 is removed and separated from the first frame 22, the power module 21 is separated from the second power connection terminal g2. Exemplarily, each power module 21 can be detachably connected to the second power connection terminal g2 via a cable assembly 6. The second power connection terminal g2 on the first frame 22 is used to connect to the first power connection terminal g1 of the switch assembly 51. When the first frame 22 of the power cabinet 2 is installed in the cabinet 1, the second power connection terminal g2 can contact and electrically connect with the first power connection terminal g1. When the first frame 22 of the power cabinet 2 is removed from the cabinet 1, the second power connection terminal g2 and the first power connection terminal g1 can be disconnected.

[0085] As can be seen from Figure 3a, an electrical connection breakpoint between the power cabinet 2 and the cabinet body 1 can be formed between the second power connection terminal g2 and the first power connection terminal g1, so that the first frame 22 of the power cabinet 2 can be detachably removed relative to the cabinet body 1, and the second power connection terminal g2 and the cable assembly 6 and other distribution devices on the first frame 22 can be removed from the cabinet body 1 along with the first frame 22, at which time these distribution devices can be maintained. At the same time, the power module 21 detachably mounted on the first frame 22 can also be removed from the first frame 22. For the entire uninterruptible power supply cabinet 10, the power module 21 can be replaced at the first level, and the distribution devices on the power cabinet 2 can be replaced at the second level. Compared with the existing technology, the distribution devices such as copper busbars and cables that were generally not replaceable before can be removed and removed for maintenance, which improves the convenience of maintenance, improves the reliability of the system, and saves maintenance time.

[0086] Of course, the uninterruptible power supply cabinet 10 also includes a bypass module 31 and a control module 41. In the uninterruptible power supply cabinet 10 shown in Figure 3b, the bypass module 31 and the control module 41 are arranged between the switch assembly 51 and the power cabinet 2. The control module 41 is signal-connected to each power module 21 and the bypass module 31 respectively.

[0087] Figure 3c shows a schematic circuit diagram of the uninterruptible power supply cabinet 10 shown in Figure 3b. As shown in Figure 3c, the uninterruptible power supply cabinet 10 has an input and output integrated into an external port 101. The input is used to connect to a power source, which specifically includes a bypass input, a main input, and a battery input. The output is used to connect to a load. An uninterruptible power supply network is formed between the input and output terminals, which is used to convert electrical energy input from the input terminal and supply it to the load through the output terminal. Multiple power modules 21 are connected in parallel to form a power module assembly. The power module assembly is connected to the main input and the battery input, respectively, and the output side of the power module assembly is connected to the output terminal. The output side of the bypass module 31 is connected in parallel with the output side of the power module assembly and then connected to the output terminal. The switch assembly 51 specifically includes a main switch, a bypass switch, an output switch, and a maintenance bypass switch. The main switch is set between the main input and , the bypass switch is set between the bypass input and the bypass module 31, the output switch is set between the node after the output side of the power module assembly and the output side of the bypass module 31 are connected in parallel and the output end, and the maintenance bypass switch is set between the bypass input and the output end. The breakpoints D formed between the first power connection end g1 of the cabinet 1 and the second power connection end g2 of the power cabinet 2 are distributed in multiple places, specifically including the breakpoint D1 between the power module assembly formed by the main switch and multiple power modules 21 in parallel, the breakpoint D2 between the power module assembly formed by the battery input and multiple power modules 21 in parallel, and the breakpoint D3 between the power module assembly formed by multiple power modules 21 in parallel and the output switch. When the power cabinet 2 is installed in the cabinet 1, these breakpoints D can be connected so that each power module 21 can be connected to the power supply network. When the power cabinet 2 is moved out of the cabinet 1, these breakpoints D can be disconnected.

[0088] For example, the breakpoint D1 between the power module assembly formed by connecting multiple power modules 21 in parallel and the main switch can be achieved by a removable connection of a fuse device. The breakpoint D3 between the power module assembly formed by connecting multiple power modules 21 in parallel and the output switch can also be achieved by a removable connection of a fuse device, thereby enhancing circuit reliability. The breakpoint D2 between the power module assembly formed by connecting multiple power modules 21 in parallel and the battery input terminal can be achieved by a removable connection of a copper busbar assembly.

[0089] Based on the uninterruptible power supply cabinet 10 shown in Figure 3b, an uninterruptible power supply cabinet 10 shown in Figure 4a includes a bypass cabinet 3 disposed within the cabinet body 1. Exemplarily, the bypass cabinet 3 is disposed between the control module 41 and the power cabinet 2. The bypass cabinet 3 includes a second frame 32 and a bypass module 31 removably mounted on the second frame 32. The structure differs from that shown in Figure 3b in that the bypass module 31 in Figure 4a is removably mounted on the second frame 32 of the bypass cabinet 3, allowing the bypass module 31 to be removed from the second frame 32 for easy replacement and maintenance. The cabinet body 1 is also provided with a first bypass connection terminal p1. Specifically, the switch assembly 51 can be connected to the first bypass connection terminal p1 via a copper busbar assembly 7. The second frame 32 of the bypass cabinet 3 includes a second bypass connection terminal p2, to which the bypass module 31 is removably electrically connected. When the bypass module 31 is installed on the second frame 32 and is in the installation position, the bypass module 31 is electrically connected to the second bypass connection end p2. When the bypass module 31 is disassembled and separated from the second frame 32, the bypass module 31 is separated from the second bypass connection end p2. Exemplarily, the bypass module 31 can be detachably connected to the second bypass connection end p2 through a cable assembly or other distribution device. The second bypass connection end p2 on the second frame 32 is used to connect to the first bypass connection end p1 of the cabinet 1. When the second frame 32 of the bypass cabinet 3 is installed in the cabinet 1, the second bypass connection end p2 and the first bypass connection end p1 can be in contact to achieve electrical connection. When the second frame 32 of the bypass cabinet 3 is moved out of the cabinet 1, the second bypass connection end p2 and the first bypass connection end p1 can be disconnected.

[0090] As can be seen from Figure 4a, the second bypass connection terminal p2 and the first bypass connection terminal p1 can form an electrical connection breakpoint between the bypass cabinet 3 and the cabinet body 1, so that the second frame 32 of the bypass cabinet 3 can be detachably removed relative to the cabinet body 1, and the second bypass connection terminal p2 and other distribution devices included on the second frame 32 can be removed from the cabinet body 1 along with the second frame 32, at which time these distribution devices can be maintained. At the same time, the bypass module 31 detachably mounted on the second frame 32 can also be removed from the second frame 32. For the entire uninterruptible power supply cabinet 10, the bypass module 31 can be replaced at the first level, and the distribution devices on the second frame 32 of the bypass cabinet 3 can be replaced at the second level. Compared with the existing technology, the distribution devices such as copper busbars and cables that were generally non-replaceable before can be removed and maintained, which improves the convenience of maintenance and can also improve the reliability of the system.

[0091] FIG4b shows a circuit schematic diagram of the uninterruptible power supply cabinet 10 shown in FIG4a. As shown in FIG4b, the breakpoints D formed between the first bypass power connection terminal p1 of the cabinet 1 and the second bypass connection terminal p1 of the bypass cabinet 3 are distributed in two places, specifically including the breakpoint D4 between the bypass switch and the bypass module 31, and the breakpoint D5 between the bypass module 31 and the output switch. When the bypass cabinet 3 is installed in the cabinet 1, these breakpoints D can all be connected so that the bypass module 31 can be connected to the power supply network. When the bypass cabinet 3 is moved out of the cabinet 1, these breakpoints D can all be disconnected. Among them, the breakpoint D formed between the first power connection terminal g1 of the cabinet 1 and the second power connection terminal g2 of the power cabinet 2 is similar to that in FIG3c and will not be repeated here.

[0092] For example, the breakpoint D4 between the bypass module 31 and the bypass switch can be realized by a detachable connection of a copper busbar assembly, and the breakpoint D5 between the bypass module 31 and the output switch can be realized by a detachable connection of a copper busbar assembly.

[0093] In some embodiments, based on the uninterruptible power supply cabinet 10 shown in FIG3b , an uninterruptible power supply cabinet 10 such as that shown in FIG5a includes a control cabinet 4 disposed within the cabinet body 1. For example, the control cabinet 4 is disposed on top of the bypass module 31. The control cabinet 4 includes a third frame 42 and a control module 41 detachably mounted on the third frame 42. This differs from the structure shown in FIG3b in that the control module 41 is detachably mounted on the third frame 42 of the control cabinet 4, allowing the control module 41 to be removed from the third frame 42 for easy replacement and maintenance.

[0094] Figure 5b shows a schematic circuit diagram of the uninterruptible power supply cabinet 10 shown in Figure 5a. The control module 41 can be signal-connected to the bypass module 31 and each power module 21, which can be a wired connection or a wireless connection. Of course, when the control module 41 is wired to the bypass module 31 and the power module 21, the cabinet 1, the first frame 22, and the third frame 42 can be provided with power distribution components for connecting the control module 41, the power module 21, and the bypass module 31, and these power distribution components can be removably electrically connected. When the control module 41 is installed on the third frame 42 and is in the installation position, the control module 41 can be electrically connected to the bypass module 31 and the power module 21. When the control module 41 is removed from the third frame 42, if the control module 41 is wired to the bypass module 31 and the power module 21, the control module 41 can be removed from the bypass module 31 and the power module 21.

[0095] The third frame 42 of the control cabinet 4 can be removed from the cabinet body 1, allowing maintenance of the power distribution components on the third frame 42. Simultaneously, the control module 41, which is detachably mounted on the third frame 42, can also be removed from the third frame 42. For the entire uninterruptible power supply cabinet 10, the control module 41 can be replaced at the first level, and the power distribution components on the third frame 42 of the control cabinet 4 can be replaced at the second level. Compared to existing technologies, previously non-replaceable power distribution components such as copper busbars and cables can now be removed and maintained, improving maintenance convenience and enhancing system reliability.

[0096] In conjunction with the structures of the uninterruptible power supply cabinet 10 shown in Figures 3b, 4a, and 5a, Figure 6a illustrates another structure of an uninterruptible power supply cabinet 10. As shown in Figure 6a, the uninterruptible power supply cabinet 10 includes a power cabinet 2, a bypass cabinet 3, and a control cabinet 4. The power cabinet 2 includes a first frame 22 and a plurality of power modules 21 removably mounted thereon. The bypass cabinet 3 includes a second frame 32 and a bypass module 31 removably mounted thereon. The control cabinet 4 includes a control module 41 removably mounted on a third frame 42. The cabinet 1 is provided with a first power connection terminal g1 and a first bypass connection terminal p1. One end of the switch assembly 51 is connected to the external port 101, and the other end is connected to the first power connection terminal g1 and the first bypass connection terminal p1, respectively, via two copper busbar assemblies 7. The first frame 22 is provided with a second power connection g2 for removably electrically connecting to the first power connection g1, and the second frame 32 is provided with a second bypass connection p2 for removably electrically connecting to the first bypass connection p1. The first power connection g1 and the second power connection g2 form an electrical connection point D between the cabinet 1 and the power cabinet 2, while the first bypass connection p1 and the second bypass connection p2 form an electrical connection point D between the cabinet 1 and the bypass cabinet 3. The power module 21 is removably electrically connected to the second power connection g2 via a cable assembly 6, and the bypass module 31 is removably electrically connected to the second bypass connection p2 via a power distribution device such as a cable assembly. For the entire uninterruptible power supply cabinet 10, the power module 21, the bypass module 31 and the control module 41 can be replaced at the first level, and the distribution devices on the power cabinet 2, the distribution devices on the bypass cabinet 3, and the distribution devices on the control cabinet 4 can be replaced at the second level. Compared with the existing technology, the copper busbars, cables and other distribution devices that were generally non-replaceable before can be disassembled and removed for maintenance, which improves the convenience of maintenance and can also improve the reliability of the system.

[0097] Figure 6b shows the circuit schematic of the uninterruptible power supply cabinet 10 shown in Figure 6a. The breakpoints D formed between the first power connection g1 of cabinet 1 and the second power connection g2 of power cabinet 2 are distributed at multiple locations, specifically including breakpoint D1 between the power module assembly formed by the main switch and multiple power modules 21 connected in parallel, breakpoint D2 between the power module assembly formed by the battery input and multiple power modules 21 connected in parallel, and breakpoint D3 between the power module assembly formed by multiple power modules 21 connected in parallel and the output switch. When power cabinet 2 is installed in cabinet 1, all of these breakpoints D can be connected, allowing each power module 21 to access the power supply network. The breakpoints D formed between the first bypass power connection p1 of cabinet 1 and the second bypass connection p1 of bypass cabinet 3 are distributed at two locations, specifically including breakpoint D4 between the bypass switch and bypass module 31, and breakpoint D5 between bypass module 31 and the output switch. When bypass cabinet 3 is installed in cabinet 1, all of these breakpoints D can be connected, allowing bypass module 31 to access the power supply network. When the power cabinet 2 and the bypass cabinet 3 are moved out of the cabinet 1 , these breakpoints D can be disconnected.

[0098] In a specific implementation, the uninterruptible power supply cabinet 10 can integrate different modules into one cabinet to facilitate installation and removal, while also saving space and optimizing the arrangement of components. In the following embodiments, different layouts of the uninterruptible power supply cabinet 10 will be introduced.

[0099] In an uninterruptible power supply cabinet 10 as shown in Figure 7a, the uninterruptible power supply cabinet 10 includes a power cabinet 2, which includes a first frame 22 and a power module 21 removably mounted on the first frame 22. The first power connection terminal g1 of the cabinet body 1 is removably connected to the second power connection terminal g2 on the first frame 22 to form an electrical connection breakpoint D. Each power module 21 is removably mounted on the first frame 22, so that the power module 21 can be removed from the first frame 22 to facilitate replacement and maintenance. The bypass module 31 is also removably mounted on the first frame 22, so that the bypass module 31 can be removed from the first frame 22 to facilitate replacement and maintenance. The bypass module 31 and each power module 21 are respectively removably electrically connected to the second power connection terminal g2 of the first frame 22.

[0100] When the first frame 22 of the power cabinet 2 is installed in the cabinet body 1, the second power connection terminal g2 and the first power connection terminal g1 can be in contact to achieve electrical connection. When the first frame 22 of the power cabinet 2 is moved out of the cabinet body 1, the second power connection terminal g2 and the first power connection terminal g1 can be disconnected. When the bypass module 31 and multiple power modules 21 are installed on the first frame 22 and are in the installation position, the bypass module 31 and the multiple power modules 21 are electrically connected to the second power connection terminal g2 respectively. When the bypass module 31 is disassembled and separated from the first frame 22, the bypass module 31 is separated from the second power connection terminal g2; when the power module 21 is disassembled and separated from the first frame 22, the power module 21 is separated from the second power connection terminal g2.

[0101] As can be seen from Figure 7a, the second power connection end g2 and the first power connection end g1 can form an electrical connection breakpoint between the power cabinet 2 and the cabinet body 1, allowing the first frame 22 of the power cabinet 2 to be detachably removed from the cabinet body 1. The second power connection end g2 and distribution components such as the cable assembly 6 on the first frame 22 can be removed from the cabinet body 1 along with the first frame 22, allowing these distribution components to be maintained. At the same time, the power module 21 and bypass module 31 detachably mounted on the first frame 22 can also be removed from the first frame 22. For the entire uninterruptible power supply cabinet 10, the power module 21 and bypass module 31 can be replaced at the first level, and the distribution components on the power cabinet 2 for connecting the power module 21 and the switch assembly 51, as well as the distribution components for connecting the bypass module 31 and the switch assembly 51, can be replaced at the second level. Compared to the prior art, distribution components such as copper busbars and cables that were previously generally non-replaceable can now be removed and removed for maintenance, improving maintenance convenience and also increasing system reliability.

[0102] Figure 7b shows a schematic circuit diagram of the uninterruptible power supply cabinet 10 shown in Figure 7a. The breakpoints D formed between the second power connection terminal g2 of the cabinet body 1 and the first power connection terminal g1 of the power cabinet 2 are distributed in multiple locations, specifically including a breakpoint D1 between the power module assembly formed by the main switch and multiple power modules 21 in parallel, a breakpoint D2 between the power module assembly formed by the battery input and multiple power modules 21 in parallel, a breakpoint D3 between the power module assembly formed by multiple power modules 21 in parallel and the output switch, a breakpoint D4 between the bypass module 31 and the bypass switch, and a breakpoint D5 between the bypass module 31 and the output switch. When the power cabinet 2 is installed in the cabinet 1, these breakpoints D can all be connected so that each power module 21 and bypass module 31 can be connected to the power supply network. When the power cabinet 2 is removed from the cabinet 1, these breakpoints D can all be disconnected.

[0103] FIG8 a shows another uninterruptible power supply cabinet 10 based on the uninterruptible power supply cabinet 10 shown in FIG7 a. As shown in FIG8 a, a control module 41 is detachably mounted on the first frame 22 of the power cabinet 2. In other words, the control module 41, the bypass module 31, and the plurality of power modules 21 are integrated within the power cabinet 2.

[0104] In the uninterruptible power supply cabinet 10 shown in FIG8a , the first frame 22 of the power cabinet 2 can be detachably removed from the cabinet body 1, and the power distribution components including the second power connection terminal g2 and the cable assembly 6 on the first frame 22 can be removed from the cabinet body 1 along with the first frame 22, at which time these power distribution components can be maintained. The power module 21, bypass module 31, and control module 41 detachably mounted on the first frame 22 can also be removed from the first frame 22. For the entire uninterruptible power supply cabinet 10, the power module 21, bypass module 31, and control module 41 can be replaced at the first level, and the power distribution components on the power cabinet 2 can be replaced at the second level. Compared with the prior art, the power distribution components such as copper busbars and cables that were previously non-replaceable can now be removed and removed for maintenance, which improves the convenience of maintenance and also increases the reliability of the system.

[0105] Figure 8b shows a schematic circuit diagram of the uninterruptible power supply cabinet 10 shown in Figure 8a. The control module 41 can be signal-connected to the bypass module 31 and each power module 21, either by wired or wireless connection. Of course, when the control module 41 is wired to the bypass module 31 and power module 21, the connection is removable.

[0106] Based on the UPS cabinet 10 shown in Figure 7a, Figure 9a shows an UPS cabinet 10 including a control cabinet 4. As shown in Figure 9a, the control cabinet 4 includes a third frame 42 and a control module 41 detachably mounted on the third frame 42.

[0107] In the uninterruptible power supply cabinet 10 shown in Figure 9a, the first frame 22 of the power cabinet 2 can be removably removed from the cabinet body 1. The power distribution components, such as the second power connection terminal g2 and the cable assembly 6, on the first frame 22 can be removed from the cabinet body 1 along with the first frame 22, allowing maintenance on these power distribution components. The power module 21 and bypass module 31, which are removably mounted on the first frame 22, can also be removed from the first frame 22. Furthermore, the third frame 42 of the control module 4 can be removably removed from the cabinet body 1, allowing maintenance on the power distribution components on the third frame 42. The control module 41, which is removably mounted on the third frame 42, can also be removed from the third frame 42. For the entire uninterruptible power supply cabinet 10, the power module 21, bypass module 31, and control module 41 can be replaced at the first level, and the distribution components on the power cabinet 2 and control cabinet 3 can be replaced at the second level. Compared with the existing technology, the copper busbars, cables and other distribution components that were generally non-replaceable before can be disassembled and removed for maintenance, which improves the convenience of maintenance and can also improve the reliability of the system.

[0108] Figure 9b shows a schematic circuit diagram of the uninterruptible power supply cabinet 10 shown in Figure 9a. The control module 41 can be signal-connected to the bypass module 31 and each power module 21, either by wired or wireless connection. Of course, when the control module 41 is wired to the bypass module 31 and power module 21, the connection is removable.

[0109] As shown in Figure 10a, an uninterruptible power supply cabinet 10 includes a power cabinet 2 and a bypass cabinet 3. The power cabinet 2 includes a first frame 22 and a power module 21 removably mounted on the first frame 22. The first power connection terminal g1 of the cabinet 1 is removably connected to the second power connection terminal g2 on the first frame 22 to form an electrical connection point D. Each power module 21 is removably mounted on the first frame 22, allowing the power module 21 to be removed from the first frame 22 for easy replacement and maintenance. The bypass cabinet 3 includes a second frame 32 and a power module 31 removably mounted on the second frame 32. The first bypass connection terminal p1 of the cabinet 1 is removably connected to the second bypass connection terminal p2 on the second frame 32 to form an electrical connection point D. The control module 41 is also removably mounted on the second frame 32, allowing the control module 41 to be removed from the second frame 32 for easy replacement and maintenance.

[0110] When the first frame 22 of the power cabinet 2 is installed in the cabinet 1, the second power connection terminal g2 and the first power connection terminal g1 can be in contact to achieve electrical connection. When the first frame 22 of the power cabinet 2 is moved out of the cabinet 1, the second power connection terminal g2 and the first power connection terminal g1 can be disconnected. When multiple power modules 21 are installed on the first frame 22 and are in the installation position, the multiple power modules 21 are electrically connected to the second power connection terminal g2 respectively. When the power module 21 is disassembled and separated from the first frame 22, the power module 21 is separated from the second power connection terminal g2. When the second frame 32 of the bypass cabinet 3 is installed in the cabinet 1, the second bypass connection terminal p2 and the first bypass connection terminal p1 can be in contact to achieve electrical connection. When the second frame 32 of the bypass cabinet 3 is moved out of the cabinet 1, the second bypass connection terminal p2 and the first bypass connection terminal p1 can be disconnected, and the control module 41 can also be moved out with the second frame 32. When the bypass module 31 is installed on the second frame 32 and is in the installation position, the bypass module 31 is electrically connected to the second bypass connection end p1 , and the control module 41 is signal-connected to the bypass module 31 and the plurality of power modules 21 .

[0111] As can be seen from Figure 10a, an electrical connection breakpoint between the power cabinet 2 and the cabinet body 1 can be formed between the second power connection terminal g2 and the first power connection terminal g1, so that the first frame 22 of the power cabinet 2 can be detachably removed relative to the cabinet body 1, and the second power connection terminal g2 and the cable assembly 6 and other distribution devices on the first frame 22 can be removed from the cabinet body 1 along with the first frame 22, at which time these distribution devices can be maintained. At the same time, the power module 21 detachably mounted on the first frame 22 can also be removed from the first frame 22. An electrical connection breakpoint between the bypass cabinet 3 and the cabinet body 1 can be formed between the second bypass connection terminal p2 and the first power connection terminal p1, so that the second frame 32 of the bypass cabinet 3 can be detachably removed relative to the cabinet body 1, and the second bypass connection terminal p2 and other distribution devices on the second frame 32 can be removed from the cabinet body 1 along with the second frame 32, at which time these distribution devices can be maintained. At the same time, the control module 41 detachably mounted on the second frame 32 can also be removed from the second frame 32.

[0112] For the entire uninterruptible power supply cabinet 10, the power module 21, the bypass module 31 and the control module 41 can be replaced at the first level, and the distribution devices on the power cabinet 2 and the distribution devices on the bypass cabinet 3 can be replaced at the second level. Compared with the existing technology, the copper busbars, cables and other distribution devices that were generally non-replaceable before can be disassembled and removed for maintenance, which improves the convenience of maintenance and can also improve the reliability of the system.

[0113] Figure 10b shows the circuit schematic of the uninterruptible power supply cabinet 10 shown in Figure 10a. The breakpoints D formed between the second power connection terminal g2 of the cabinet 1 and the first power connection terminal g1 of the power cabinet 2 are distributed in multiple locations, specifically including a breakpoint D1 between the power module assembly formed by the main switch and multiple power modules 21 connected in parallel; a breakpoint D2 between the power module assembly formed by the battery input and multiple power modules 21 connected in parallel; a breakpoint D3 between the power module assembly formed by multiple power modules 21 connected in parallel and the output switch; a breakpoint D4 between the bypass module 31 and the bypass switch; and a breakpoint D5 between the bypass module 31 and the output switch. When the power cabinet 2 is installed in the cabinet 1, these breakpoints D can all be connected, allowing each power module 21 and bypass module 31 to access the power supply network. When the power cabinet 2 and bypass cabinet 3 are removed from the cabinet 1, these breakpoints D can all be disconnected.

[0114] In other embodiments, based on the structure shown in FIG3b , an uninterruptible power supply cabinet 10 as shown in FIG11a includes a switch cabinet 5, which includes a fourth frame 52 and a switch assembly 51 detachably mounted thereto. The cabinet 1 includes a first power connection terminal g1, a first cable connection terminal q1, and a first switch connection terminal k1 connected to the external port 101. The first power connection terminal g1 and the first cable connection terminal q1 can be connected via a copper busbar assembly 7. The fourth frame 52 includes a second switch connection terminal k2, which is configured to be detachably electrically connected to the first switch connection terminal k1. The second switch connection terminal k2 and the first switch connection terminal k1 form an electrical connection point D between the switch cabinet 5 and the cabinet 1. The fourth frame 52 of the switch cabinet 5 also includes a second cable connection terminal q2, which is configured to be detachably electrically connected to the first cable connection terminal q1, forming another electrical connection point D between the switch cabinet 5 and the cabinet 1. The first power connection terminal g1 is detachably electrically connected to the second power connection terminal g2 of the power cabinet 2, forming an electrical connection breakpoint D between the power cabinet 2 and the cabinet body 1. When the fourth frame 52 of the switch cabinet 5 is installed in the cabinet body 1, the second switch connection terminal k2 and the first switch connection terminal k1 can contact and achieve electrical connection, and the second cable connection terminal q2 and the first cable connection terminal q1 can contact and achieve electrical connection. When the first frame 22 of the power cabinet 2 is removed from the cabinet body 1, the second power connection terminal g2 and the first power connection terminal g1 can be disconnected, and the second cable connection terminal q2 and the first cable connection terminal q1 are disconnected. The bypass module 31 is illustratively connected to the first cable connection terminal q1 via a power distribution device such as a copper busbar.

[0115] As can be seen in Figure 11a, the second power connection terminal g2 and the first power connection terminal g1 form an electrical connection breakpoint D between the power cabinet 2 and the cabinet body 1, allowing the first frame 22 of the power cabinet 2 to be removably removed from the cabinet body 1. The second power connection terminal g2 and the power distribution components, such as the cable assembly 6, on the first frame 22 can be removed from the cabinet body 1 along with the first frame 22, allowing maintenance on these power distribution components. The second cable connection terminal q2 and the first cable connection terminal q1, as well as the second switch connection terminal k2 and the first switch connection terminal k1, respectively form two electrical connection breakpoints D between the switch cabinet 5 and the cabinet body 1. This allows the fourth frame 52 of the switch cabinet 5 to be removably removed from the cabinet body 1. The power distribution components, including the second switch connection terminal k2 and the second cable connection terminal q2, on the fourth frame 52 can be removed from the cabinet body 1 along with the fourth frame 52, allowing maintenance on these power distribution components. At the same time, the power module 21 detachably mounted on the first frame 22 can be removed from the first frame 22, and the switch assembly 51 detachably mounted on the fourth frame 52 can also be removed from the fourth frame 52. For the entire uninterruptible power supply cabinet 10, the power module 21 and the switch assembly 51 can be replaced at a single level, and the power distribution components on the power cabinet 2 and the power distribution components on the switch cabinet 5 can be replaced at a second level. Compared to the prior art, previously non-replaceable power distribution components such as copper busbars and cables can now be removed for maintenance, improving maintenance convenience and enhancing system reliability.

[0116] Figure 11b shows the circuit schematic of the uninterruptible power supply cabinet 10 shown in Figure 11a. The breakpoints D formed between the second power connection terminal g2 of the power cabinet 2 and the first power connection terminal g1 of the cabinet 1 are distributed at multiple locations, including a breakpoint D1 between the power module assembly formed by the main switch and multiple power modules 21 in parallel, a breakpoint D2 between the power module assembly formed by the battery input and multiple power modules 21 in parallel, a breakpoint D3 between the power module assembly formed by multiple power modules 21 in parallel and the output switch, a breakpoint D4 between the bypass module 31 and the bypass switch, and a breakpoint D5 between the bypass module 31 and the output switch. The breakpoints D formed between the second wiring connection terminal q2 of the switch cabinet 5 and the first wiring connection terminal q1 of the cabinet 1 are distributed at multiple locations, including another breakpoint D6 between the power module assembly formed by the main switch and multiple power modules 21 in parallel, another breakpoint D7 between the power module assembly formed by multiple power modules 21 in parallel and the output switch, and another breakpoint D13 between the bypass switch and the bypass module 31. Breakpoints D13 and D4 are both located between the bypass switch and the bypass module 31. Breakpoint D13 is formed by the second cable connection terminal q2 and the first cable connection terminal q1, while breakpoint D4 is formed by the second power connection terminal g2 and the first power connection terminal g1 of the cabinet 1. Breakpoints D, formed between the second switch connection terminal k2 of the switch cabinet 5 and the first switch connection terminal k1 of the cabinet 1, are distributed in multiple locations, including breakpoint D8 between the main switch and the main input, breakpoint D9 between the bypass switch and the bypass input, breakpoint D10 between the maintenance bypass switch and the bypass input, breakpoint D11 between the maintenance bypass switch and the output terminal, and breakpoint D12 between the output switch and the output terminal. When the power cabinet 2 and switch cabinet 5 are removed from the cabinet 1, these breakpoints D can be disconnected.

[0117] Building on the structure shown in Figure 11a, Figure 12a illustrates an uninterruptible power supply cabinet 10, in which the control module 41 is removably mounted to the fourth frame 52 of the switch cabinet 5. Figure 12b shows a schematic circuit diagram of the uninterruptible power supply cabinet 10 shown in Figure 12a. Aside from the structure of the control module 41 and the fourth frame 52, the remaining electrical connections are similar to those in Figure 12b and will not be further described here. It should be understood that the control module 41 and the switch assembly 51 share a cabinet, which can be considered as the control module 41 being integrated into the switch cabinet 5 or the switch assembly 51 being integrated into the control cabinet 4. In other words, the fourth frame 52 in Figures 12a and 12b can also be considered as the third frame 42.

[0118] Building on the structure shown in Figure 12a, Figure 13a shows an uninterruptible power supply cabinet 10 in which the bypass module 31 is removably mounted on the fourth frame 52 of the switch cabinet 5. The bypass module 31 and the switch assembly 51 are electrically connected via the power distribution components on the fourth frame 52. Figure 13b shows a schematic circuit diagram of the uninterruptible power supply cabinet 10 shown in Figure 13a. Aside from the structure of the bypass module 31 and the fourth frame 52, the remaining electrical connections are similar to those in Figure 12a and are not further described here. It should be understood that the bypass module 31, control module 41, and switch assembly 51 share a cabinet. This can be considered as the bypass module 31 and control module 41 being integrated into the switch cabinet 5, the switch assembly 51 and bypass module 31 being integrated into the control cabinet 4, or the switch assembly 51 and control module 41 being integrated into the bypass cabinet 3. In other words, the fourth frame 52 in Figures 13a and 13b can also be considered as the third frame 42 or the second frame 32.

[0119] Based on the idea that the switch assembly 51 is replaceable, and in combination with different integration methods of the power module 21, the bypass module 31, and the control module 41, the embodiments of the present application also provide the following implementation methods of the uninterruptible power supply cabinet 10.

[0120] In an uninterruptible power supply cabinet 10 as shown in FIG14a , a bypass module 31 is detachably mounted on the first frame 22 of the power cabinet 2. The bypass module 31 is detachably electrically connected to the second power connection terminal g2 of the power cabinet 2. When the power cabinet 2 is installed in the cabinet body 1, the bypass module 31 can be detachably electrically connected to the first power connection terminal g1 in the cabinet body 1 via the second power connection terminal g2 of the power cabinet 2.

[0121] Figure 14b shows the circuit schematic of the uninterruptible power supply cabinet 10 shown in Figure 14a. The breakpoints D formed between the second power connection terminal g2 of the power cabinet 2 and the first power connection terminal g1 of the cabinet 1 are distributed in multiple locations, including a breakpoint D1 between the power module assembly formed by the main switch and multiple power modules 21 in parallel, a breakpoint D2 between the power module assembly formed by the battery input and multiple power modules 21 in parallel, and a breakpoint D3 between the power module assembly formed by the multiple power modules 21 in parallel and the output switch.

It should be understood that the control module 41 and the bypass module 31 share a cabinet, and this can be considered as the control module 41 being integrated into the bypass cabinet 3 or the bypass module 31 being integrated into the control cabinet 4. In other words, the second frame 32 in Figures 19a and 19b can also be considered as the third frame 42.

The power module 21, the bypass module 31, and the control module 41 are all removably mounted on the fourth frame 52, and the power module 21 and the bypass module 31 are each removably electrically connected to the second switch connection terminal k2. When the fourth frame 52 of the switch cabinet 5 is installed in the cabinet 1, the second switch connection terminal k2 and the first switch connection terminal k1 can contact and electrically connect.

[0133] Figure 23b shows the circuit schematic of the uninterruptible power supply cabinet 10 shown in Figure 23a. The breakpoints D formed between the second switch connection terminal k2 of the switch cabinet 5 and the first switch connection terminal k1 of the cabinet body 1 are distributed in multiple locations, including breakpoint D8 between the main switch and the main input, breakpoint D9 between the bypass switch and the bypass input, breakpoint D10 between the maintenance bypass switch and the bypass input, breakpoint D11 between the maintenance bypass switch and the output terminal, and breakpoint D12 between the output switch and the output terminal.

[0134] As can be seen from the above embodiments, the uninterruptible power supply cabinet 10 provided in the present embodiment enables hot-swappable, single-level replaceability of modules such as the power module 21, bypass module 31, control module 41, and switch assembly 51. Furthermore, integrated design of power distribution components such as copper busbars and cables can be implemented to achieve secondary replaceability, allowing replacement of previously non-replaceable components within the cabinet 1, improving maintenance convenience and system reliability.

[0135] In the above embodiments, in order to facilitate the understanding of the scheme, the uninterruptible power supply cabinet 10 is a simplified structural diagram. In order to understand the scheme more intuitively, taking the structure shown in Figures 9a and 9b as an example, Figure 24 shows an assembly diagram of an uninterruptible power supply cabinet 10. As shown in Figure 24, the cabinet body 1 is in the shape of a cube as a whole. In normal use, it is placed vertically so that the height direction of the cabinet body 1 is the vertical direction. The cabinet body 1 includes a main body 11 and a cabinet door 12. The main body 11 has an opening, and the accommodating cavity R of the main body 11 is connected to the opening. The cabinet door 12 is rotatably mounted at the opening of the main body 11, and the rotation axis of the cabinet door 12 is parallel to the vertical direction. The cabinet door 12 can rotate around the rotation axis to close the opening of the main body 11 or expose the opening. At this time, the cabinet door 12 is open and the accommodating cavity R is exposed.

[0136] The uninterruptible power supply cabinet 10 includes a power cabinet 2 and a control cabinet 4. For example, the power cabinet 2 includes a first frame 22 and a plurality of power modules 21, which are detachably mounted on the power cabinet 2. The control cabinet 4 includes a third frame 42 and a control module 41, which is detachably mounted on the control cabinet 4. The uninterruptible power supply cabinet 10 also includes a bypass module 31, which is detachably mounted on the first frame 22, specifically above the plurality of power modules 21. In FIG. 24 , the structure of the switch assembly 51 is not shown.

[0137] In conjunction with Figures 9a and 9b, please continue to refer to Figure 24. The first power connection terminal g1 of the cabinet 1 includes a first main circuit connection fuse g11, a first battery copper busbar g12, a first output connection fuse g13, a first bypass input copper busbar g14, and a first bypass output copper busbar g15. The second power connection terminal g2 on the first frame 22 includes a second main circuit copper busbar g21, a second battery copper busbar g22, a second output copper busbar g23, a second bypass input copper busbar g24, and a second bypass output copper busbar g25. As shown in Figure 24, the second power connection terminal g1 is located on the top surface of the first frame 22. The second power connection terminal g1 comprises multiple connectors arranged at the edge of the top surface of the first frame 22, facilitating connection with the first power connection terminal g1 within the cabinet 1 and facilitating maintenance and replacement. The second bypass input copper busbar g24 and the second bypass output copper busbar g25 are located on the top edge of the frame, where they meet the backplane. The second main copper busbar g21 and the second output copper busbar g23 are located on the top edge of the frame, where they meet the sidewall. The first main circuit connection fuse g11 and the second main circuit busbar g21 form a breakpoint D1 between the main switch and the power module assembly formed by the multiple power modules 21 connected in parallel. The first battery copper busbar g12 and the second battery copper busbar g22 form a breakpoint D2 between the battery input and the power module assembly formed by the multiple power modules 21 connected in parallel. The first output connection fuse g13 and the second output copper busbar g23 form a breakpoint D3 between the power module assembly formed by the multiple power modules 21 connected in parallel and the output switch. The first bypass input copper busbar g14 and the second bypass input copper busbar g24 form a breakpoint D4 between the bypass module 31 and the bypass switch. The first bypass output copper busbar g15 and the second bypass output copper busbar g25 form a breakpoint D5 between the bypass module 31 and the output switch.

[0138] Figure 25a shows the structure of the cabinet 1. Inside the accommodating cavity R, the main body 11 is provided with a first slide rail 111, allowing the first frame 22 of the power cabinet 2 to slide with the first slide rail 111. When the cabinet door 12 is opened to expose the accommodating cavity R, the first frame 22 can slide out of the accommodating cavity R along the first slide rail 111.

[0139] Figure 25b shows the structure of the first frame 22 of the power cabinet 2. The first frame 22 is an open box-like structure, internally provided with a plurality of first mounting slots 211 for mounting the power module 21, and a second mounting slot 212 for mounting the bypass module 31. To facilitate the installation and removal of the power module 21 and the bypass module 31, second slide rails 213 can be installed inside the first and second mounting slots 211, 212, respectively, so that the power module 21 and the bypass module 31 can slide and engage with the corresponding second slide rails 213. The first frame 22 is also provided with a handle 214. When the first frame 22 is installed in the accommodating cavity R of the cabinet body 1, the handle 214 protrudes from the surface of the first frame 22 facing the opening of the cabinet body 1. The provision of the handle 214 makes it easier for staff to apply force to the first frame 22, thereby pulling the first frame 22 out of the accommodating cavity R of the main body 11. To ensure balanced force distribution, two handles 214 are symmetrically provided on the first frame 22, perpendicular to the vertical direction.

[0140] Continuing with Figure 25b, the top of the first frame 22 is illustratively provided with a second main copper busbar g21, a second battery copper busbar g22, a second output copper busbar g23, a second bypass input copper busbar g24, and a second bypass output copper busbar g25. The type, structure, location, and quantity of these power distribution components are merely illustrative and are not limited in this application. Specifically, these power distribution components include, but are not limited to, copper busbars, cables, terminals, fuses, and the like. When the power cabinet 2 is removed from the cabinet, these power distribution components can be removed with the first frame 22 for easy maintenance and replacement.

[0141] Figure 25c shows a schematic diagram of the structure of the power module 21 and bypass module 31. The power module 21 and bypass module 31 can be removably mounted on the first frame 22 of the power cabinet 2. When the power module 21 and bypass module 31 are mounted on the first frame 22, the power module 21 can be electrically connected to the second main copper busbar g21, the second battery copper busbar g22, and the second output copper busbar g23 on the first frame 22. The bypass module 31 can also be electrically connected to the second bypass input copper busbar g24 and the second bypass output copper busbar g25 on the first frame 22. The power module 21 and bypass module 31 can be connected to the various power distribution components in a manner including, but not limited to, hot-swappable methods. This facilitates the removability of the power module 21 and bypass module 31 relative to the first frame 22. To facilitate operator operation, a first module handle 211 is provided on the surface of the power module 21 facing the cabinet door 12, and a second module handle 311 is provided on the surface of the bypass module 31 facing the cabinet door 12. Exemplarily, two first module handles 211 are symmetrically provided, and two second module handles 311 are symmetrically provided.

[0142] Figure 25d shows the structure of a control cabinet 4. Multiple control modules 41 can be mounted on the third frame 42 of the control cabinet 4. The control modules 41 can also be hot-swappable. A third module handle 411 is provided on the surface of the control module 41 facing the cabinet door 12. The connection between the third frame 42 and the cabinet body 1 can be a plug-in port.

[0143] In some embodiments, the uninterruptible power supply cabinet 10 may further include a transfer connector, one end of which is configured to be removably electrically connected to the first power connection terminal g1, and the other end of which is configured to be removably electrically connected to the second power connection terminal g2. In other words, the first power connection terminal g1 and the second power connection terminal g2 are connected via the transfer connector, which acts as a third-party connector and is also removable and replaceable, further improving system maintenance convenience and system reliability.

A power distribution input cabinet 401 can be positioned between the first and second AC inputs 201, 202, and the UPS cabinet 10. The battery packs 203 are used to input DC power to the UPS cabinet 10. A battery junction box 50 can be positioned between the battery packs 203 and the UPS cabinet 10. The UPS cabinet 10 converts the current and supplies power to the loads, which include a first user load 301 and a second user load 302.
