Description

Technical Field

[0001] The present application relates to the field of energy storage technology, and in particular to a cabinet matching structure, an integrated cabinet and an energy storage system. Background Art

[0002] With the continuous development of energy storage technology, the application of energy storage systems is becoming more and more widespread. Energy storage systems are equipped with integrated cabinets, which can output power to the outside world through battery packs. At the same time, the integrated cabinets can also output the power generated by the power generation device after voltage stabilization and charge the battery pack.

[0003] An uninterruptible power supply (UPS) is placed inside the integrated cabinet, which is in turn arranged inside the energy storage cabinet. When arranging the integrated cabinet, the energy storage cabinet needs to be installed inside the integrated cabinet. Designing the coordination structure between different cabinets affects the production cost and coordination convenience of the cabinets. Therefore, simplifying the cabinet coordination structure and ensuring coordination convenience between cabinets is an important issue. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a cabinet matching structure, an integrated cabinet and an energy storage system, which can help simplify the cabinet matching structure and ensure the convenience of matching between cabinets.

[0005] In order to solve the above technical problems, the embodiment of the present application provides a cabinet matching structure, which includes a first cabinet, a support structure and a second cabinet. The first cabinet is provided with a first accommodating space, a second accommodating space and a third accommodating space in sequence along the first direction. The first accommodating space forms an uninterruptible power supply placement area, the second accommodating space forms a distribution component placement area, and the third accommodating space forms a bus component placement area. The first direction is parallel to the height direction of the first cabinet. The support structure includes a first support member and a second support member that are relatively arranged in the first accommodating space. The second cabinet is located in the first accommodating space, and the second cabinet abuts against the first support member and the second support member. A plug-in is provided on the side of the second cabinet close to the support structure. The plug-in forms a plug-in hole on one side of the second cabinet. The second cabinet is used to install an uninterruptible power supply.

[0006] The present application also provides an integrated cabinet comprising the aforementioned cabinet assembly structure, an uninterruptible power supply (UPS), a power distribution assembly, and a busbar assembly. The UPS is disposed within the second cabinet. The power distribution assembly is disposed within the power distribution assembly area of ​​the first cabinet. The busbar assembly is disposed within the busbar assembly area of ​​the first cabinet.

[0007] An embodiment of the present application further provides an energy storage system, which includes the above-mentioned integrated cabinet.

[0008] The cabinet matching structure, integrated cabinet, and energy storage system provided by the embodiments of the present application are provided with a support structure within the accommodation space of the first cabinet of the integrated cabinet. The support structure includes a plurality of support members, which can support the cabinet of the uninterruptible power supply, i.e., the second cabinet. The support structure can form a reserved space at the bottom of the second cabinet. The second cabinet is provided with a connector on a side close to the support structure. When the second cabinet abuts against the support structure, the connector is located within the reserved space. The connector can form a plug-in hole at the bottom of the second cabinet. The plug-in hole can be inserted with a fork to facilitate the transportation of the second cabinet, thereby improving the convenience of cabinet matching.

[0009] In some embodiments, the first and second support members include a first plate and a second plate disposed at an angle at one end. The first and second plates are each connected to the first cabinet at their other ends, and the first plate is used to support the second cabinet. This allows the different plates disposed at an angle to cooperate with each other to provide support, simplifying the structure of the support member.

[0010] In some embodiments, the angle between the first plate and the second plate is 15° to 25°. In this way, by making the angle between the different plates acute, the support strength can be ensured while reducing the space occupied.

[0011] In some embodiments, the first and second support members further include a stopper connected to the first plate, the stopper extending from an edge of the first plate and abutting against a side of the second cabinet. Thus, by providing the stopper on the edge of the first plate, the position of the second cabinet within the storage space can be restricted.

[0012] In some embodiments, the first and second support members further include a first extension portion and a second extension portion, wherein the first extension portion bends and extends from an edge of the first plate and abuts against the first cabinet, and the second extension portion bends and extends from an edge of the second plate and abuts against the first cabinet. Thus, by providing the extension portions on the edges of the plates, the mating area between the support member and the first cabinet can be ensured, thereby ensuring the fixing effect of the support member on the first cabinet.

[0013] In some embodiments, the first cabinet is provided with a first stopper and a second stopper spaced apart along the second direction. The first stopper and the second stopper are located on either side of the second cabinet and abut against the second cabinet. The second direction is perpendicular to the first direction. In this way, by providing the stopper within the first cabinet, the position of the second cabinet can be restricted, thereby preventing the second cabinet from easily moving.

[0014] In some embodiments, the first and second stoppers each include a first section and a second section located on the same plane, and a third section connecting the first and second sections, at least a portion of the third section being located on a different plane than the first section, the first and second sections being connected to the first cabinet, and at least a portion of the third section abutting against the second cabinet. Thus, forming a protruding portion on the stopper can reduce the difficulty of mating.

[0015] In some embodiments, a maximum distance between the third segment and the first segment in the second direction is 5 mm to 30 mm.

[0016] In some embodiments, there are multiple first limiters and multiple second limiters, and the multiple first limiters and multiple second limiters are arranged in sequence along the first direction. In this way, by increasing the number of limiters, it is possible to ensure that the second cabinet is limited at multiple different positions.

[0017] In some embodiments, the cabinet matching structure further includes a connecting assembly, the connecting assembly including a first connecting member and a second connecting member spaced apart in a first direction, the first connecting member and the second connecting member both connecting the first cabinet to the second cabinet. In this way, the first cabinet and the second cabinet can be connected by arranging multiple connecting members at different positions.

[0018] In some embodiments, the first connector is provided with a first mounting hole and a second mounting hole located on the same plane. The first mounting hole is used to allow a first fastener to pass through for connection to the first cabinet, and the second mounting hole is used to allow a second fastener to pass through for connection to the second cabinet. In this way, by providing different mounting holes on the first connector, the connection structure of the first connector can be simplified.

[0019] In some embodiments, the second connector includes a first abutting portion and a second abutting portion connected to each other, wherein the first abutting portion abuts against and connects to the first cabinet, and the second abutting portion abuts against and connects to the second cabinet. Thus, the second connector can be connected to the cabinet by forming a abutting portion, thereby ensuring a mating area and improving connection stability.

[0020] In some embodiments, the second connecting member further includes an enclosing portion, which is connected to the first fitting portion and encloses the first fitting portion to form a hollow area. In this way, the enclosing portion can be provided to form a handle to facilitate pulling the second cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, each embodiment of the present application will be described in detail below with reference to the accompanying drawings. However, it will be understood by those skilled in the art that in each embodiment of the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the present application can be implemented. The division of the following embodiments is for convenience of description and should not constitute any limitation on the specific implementation of the present application. The various embodiments can be combined with each other and referenced to each other under the premise of no contradiction.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0025] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and they can refer to internal connectivity between two components or interaction between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0026] Integrated cabinets are widely used electrical integration cabinets in energy storage systems. They are typically divided into multiple zones. For example, a currently used 6MW integrated cabinet is separated into two zones by a partition: a lower DC zone and an upper AC zone. The DC zone primarily serves as a DC busbar for the positive and negative outgoing wires from the high-voltage box in the energy storage system. The DC zone is where the positive and negative outgoing wires from the high-voltage box are finally connected via four busbars. A removable mounting plate is installed within the integrated cabinet, housing DC fuses and components for DC surge protection. The mounting plate can be opened using a door lock and handle, allowing it to be rotated to a certain angle for fuse removal. An uninterruptible power supply (UPS) (uninterruptible power supply) is installed in the AC zone above the integrated cabinet. The UPS cabinet has retractable rails underneath, which is not only complex but also requires high precision for coordination, making it difficult to coordinate between cabinets.

[0027] In order to simplify the cabinet matching structure and improve the convenience of cabinet matching, some embodiments of the present application provide a cabinet matching structure, in which a support member is provided in the storage space of the integrated cabinet to support the cabinet of the uninterruptible power supply. At the same time, a plug hole is formed at the bottom of the cabinet of the uninterruptible power supply, and the plug hole can be used for the fork of a handling machine such as a forklift to insert and then transport the uninterruptible power supply. When matching the cabinets, the uninterruptible power supply can be installed into the storage space of the integrated cabinet by a forklift, which can ensure the convenience of cabinet matching. At the same time, when the uninterruptible power supply needs to be moved out of the storage space of the integrated cabinet, a forklift can also be used to move the uninterruptible power supply out.

[0028] The following combination Figures 1 to 13The cabinet matching structure provided in some embodiments of the present application is described.

[0029] like Figures 1 to 13 As shown, the cabinet matching structure provided in some embodiments of the present application includes a first cabinet 11, a support structure and a second cabinet 14. The first cabinet 11 is arranged along a first direction ( Figure 1 A first storage space 101, a second storage space 102, and a third storage space 103 are sequentially arranged (in the direction indicated by the arrow P in the middle). The first storage space 101 forms the area for placing the uninterruptible power supply (UPS), the second storage space 102 forms the area for placing the power distribution components, and the third storage space 103 forms the area for placing the busbar components. The support structure includes a first support member 12 and a second support member 13 disposed relative to each other within the first storage space 101. A second cabinet 14 is located within the first storage space 101 and abuts against the first and second support members 12 and 13. A connector 141 is provided on the side of the second cabinet 14 closest to the support structure. The connector 141 forms a socket 142 on one side of the second cabinet 14. The second cabinet 14 is used to mount the UPS.

[0030] The first cabinet body 11 is a cabinet body of an integrated cabinet. Different storage spaces are formed in the first cabinet body 11, which are used to place uninterruptible power supplies, power distribution components and busbar components respectively. Different storage spaces can be formed by partitions. The first cabinet body 11 can be formed by adopting a frame structure, and the storage space can be closed by setting cabinet panels. The first direction is the vertical downward direction when the first cabinet body 11 is in use, that is, the first direction is parallel to the height direction of the first cabinet body 11. The first storage space 101 is located in the upper area of ​​the first cabinet body 11, the second storage space 102 is located in the middle of the first cabinet body 11, and the third storage space 103 is located in the lower area of ​​the first cabinet body 11.

[0031] The support structure is disposed within the first storage space 101 of the first cabinet 11 and includes a first support member 12 and a second support member 13 spaced apart from each other. The support structure supports the second cabinet 14, ensuring that the bottom of the second cabinet 14 maintains a distance from the inner wall of the first storage space 101 of the first cabinet 11. The first and second support members 12, 13 are connected and fixed to the first cabinet 11 to ensure stability during support.

[0032] The second cabinet 14 is a cabinet for an uninterruptible power supply, and is used to install the uninterruptible power supply. The second cabinet 14 is placed in the first storage space 101 of the first cabinet 11. A plug-in connector 141 is provided at the bottom of the second cabinet 14. The plug-in connector 141 forms a plug-in hole 142 at the bottom of the second cabinet 14. The plug-in hole 142 can be a blind hole or a through hole provided on the plug-in connector 141, or a groove 1411 ( Figure 6As shown, the bottom of the second cabinet 14 closes the opening at the top of the groove 1411, forming a connector hole 142. When the second cabinet 14 is mated with the first cabinet 11, the bottom of the second cabinet 14 abuts the first and second support members 12, 13 of the support structure, and the connector 141 is located within the space separated by the support structure. The connector 141 forms a connector hole 142 at the bottom of the second cabinet 14, allowing forklift insertion, facilitating the transport of the second cabinet 14 and enabling the uninterruptible power supply cabinet to be assembled or removed using a forklift.

[0033] The cabinet matching structure provided in some embodiments of the present application is provided with a support structure in the accommodation space of the first cabinet 11 of the integrated cabinet. The support structure includes a plurality of support members, which can support the cabinet of the uninterruptible power supply, that is, the second cabinet 14. The support structure can form a reserved space at the bottom of the second cabinet 14. The second cabinet 14 is provided with a connector 141 on the side close to the support structure. When the second cabinet 14 abuts against the support structure, the connector 141 is located in the reserved space. The connector 141 can form a plug hole 142 at the bottom of the second cabinet 14. The plug hole 142 can be inserted by a fork to facilitate the transportation of the second cabinet 14, thereby improving the convenience of cabinet matching.

[0034] In some embodiments, the first support member 12 and the second support member 13 include a first plate 121 and a second plate 122 set at an angle at one end, and the other ends of the first plate 121 and the second plate 122 are connected to the first cabinet 11, and the first plate 121 is used to support the second cabinet 14.

[0035] That is to say, the support member includes different plates, and there is an angle between the different plates. The different plates are all connected to the first cabinet 11 to ensure the connection strength between the support member and the first cabinet 11. The first plate 121 plays the role of supporting the second plate 122. The second plate 122 combined with the first plate 121 can ensure the overall structural strength of the support member. Different supports are arranged adjacent to different sides of the first cabinet 11, and a reserved space is formed in the area between the first support 12 and the second support 13, which can be used to accommodate the connector 141 at the bottom of the second cabinet 14. The first plate 121 and the second plate 122 of the different supports can adopt an integrally molded structure to ensure structural strength. In actual circumstances, the first plate 121 can be provided with a wiring hole so that the connecting cables inside the integrated cabinet can pass through.

[0036] In addition, the angle between the first plate 121 and the second plate 122 may be 15° to 25°.

[0037] The angle between the first plate 121 and the second plate 122 is an acute angle, which can reduce the space occupied while ensuring the support strength of the support member. Figure 8 and Figure 9 As shown, the first support member 12 and the second support member 13 are both formed by a first plate 121 and a second plate 122 in the form of an acute angle. The first plate 121 is located on a plane perpendicular to the first direction, and the second plate 122 is inclined relative to the first plate 121. The end of the second plate 122 separated from the first plate 121 is connected to the first cabinet 11. In order to facilitate the connection of the support members, cabinet panels can be provided on both sides of the first cabinet 11, and the support members can be fixed on the cabinet panels. In actual situations, the angle between the first plate 121 and the second plate 122 can be 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24° or 25°.

[0038] In some embodiments, the first support member 12 and the second support member 13 may further include a limiting portion 123 connected to the first plate 121 . The limiting portion 123 bends and extends from the edge of the first plate 121 and abuts against one side of the second cabinet 14 .

[0039] The limiting portion 123 is located at the edge of the first plate 121, and the limiting portion 123 can limit the second cabinet 14 at the edge of the first plate 121. The limiting portion 123 can be set in a plate shape, and the limiting portion 123 and the first plate 121 can be set in a vertical form. Figure 4 and Figure 5 As shown, one end of the support member having a limiting portion 123 is located at the rear side of the first cabinet 11. The limiting portion 123 abuts against the rear side of the second cabinet 14, thereby limiting the insertion position of the second cabinet 14. In actual situations, the rear side of the integrated cabinet can be enclosed by a decorative panel to the first receiving space 101.

[0040] In some embodiments, the first support member 12 and the second support member 13 may further include a first extension portion 124 and a second extension portion 125, wherein the first extension portion 124 is bent and extended from the edge of the first plate body 121 and abuts against the first cabinet body 11, and the second extension portion 125 is bent and extended from the edge of the second plate body 122 and abuts against the first cabinet body 11.

[0041] In other words, the edges of the different plates of the support member are bent and extended to form extensions, which abut against the first cabinet 11. These extensions ensure a good fit between the support member and the first cabinet 11. In practice, the extensions are provided with through-holes that allow them to be secured to the first cabinet 11 using fasteners such as screws. The extensions can be integrally formed with the plates to ensure the structural strength of the support member.

[0042] In practice, the first plate 121 of the various supports can be provided with multiple rolling elements that can rotate freely on the first cabinet 11. The rolling elements can be ball bearings or rotating shafts. During assembly and removal of the second cabinet 14, the rolling elements reduce resistance to movement of the second cabinet 14. Furthermore, there is no need to reserve significant height space for the second cabinet 14, and the second cabinet 14 can be moved within the storage space without having to raise the second cabinet 14.

[0043] In addition, a transfer platform can be set at the position of the first cabinet 11 corresponding to the second storage space 102, and the transfer platform can be transformed between a working state and a storage state. When the transfer platform is in the working state, the second cabinet 14 can be temporarily placed on the transfer platform to store or continue to transfer the second cabinet 14. When the transfer platform is in the storage state, the transfer platform can serve as a cabinet door of the second storage space 102 to close the second storage space 102. In this way, the function of the cabinet can be enriched while simplifying the cabinet structure. The transfer platform can be formed by a plate-like member and a support rod. The plate-like member can be rotatably connected to the first cabinet 11. When the plate-like member is in a horizontal state, it can be supported by a support rod to form a placement platform. After the support rod is withdrawn, the plate-like member can be retracted to close the front side of the second storage space 102.

[0044] like Figure 7 As shown, the first cabinet 11 can be provided with a first limiter 15 and a second limiter 16 spaced apart along the second direction. The first limiter 15 and the second limiter 16 are located on both sides of the second cabinet 14 and abut against the second cabinet 14. The second direction is perpendicular to the first direction.

[0045] The second direction is perpendicular to the first direction, and the second direction is the left and right direction when the integrated cabinet is actually used, and the width direction of the integrated cabinet. Different limiting members are located on different sides of the second cabinet body 14. Through the cooperation between different limiting members, the position of the second cabinet body 14 in the second direction can be limited to ensure the stability of the second cabinet body 14 in the first accommodating space 101. The limiting members can play a limiting role on the left and right sides of the second cabinet body 14 to prevent the second cabinet body 14 from shaking left and right in the accommodating space of the first cabinet body 11. In actual circumstances, connecting plates 1011 can be set on the left and right sides of the first cabinet body 11, and the connecting plates 1011 can be locked on the frame columns of the first cabinet body 11 by fasteners, and the limiting members can be locked on the connecting plates 1011 by fasteners.

[0046] In some embodiments, the first limit member 15 and the second limit member 16 may include a first section 151 and a second section 152 located on the same plane, and a third section 153 connecting the first section 151 and the second section 152, at least a portion of the third section 153 is located on a different plane from the first section 151, the first section 151 and the second section 152 are connected to the first cabinet body 11, and at least a portion of the third section 153 abuts against the second cabinet body 14.

[0047] That is, the middle portion of the position limiting member is provided in a convex shape, and the first section 151 and the second section 152 near the two ends of the position limiting member are both connected to the first cabinet 11. The first section 151 and the second section 152 can be provided with through holes so that the position limiting member can be fixed to the first cabinet 11 using fasteners. At least part of the third section 153 abuts against the second cabinet 14, that is, the third section 153 can be partially convex or the entire section can be convex. The connection between the second section 152 and the third section 153, and the connection between the first section 151 and the third section 153 can be transitioned in an inclined form or in a vertical form. In actual situations, the third section 153 can be provided with one or more protrusions, and the multiple protrusions can abut at different positions of the second cabinet 14, which can reduce the matching accuracy. At the same time, the connection between two adjacent protrusions can be located on the same plane as the first section 151, or it can be connected to the first cabinet body 11 using fasteners, thereby forming a connection with the first cabinet body 11 at more than two positions to ensure the connection strength between the limiter and the first cabinet body 11.

[0048] In addition, the maximum distance between the third section 153 and the first section 151 in the second direction may be 5 mm to 30 mm.

[0049] That is, the maximum protrusion height of the third section 153 relative to the first section 151 can be 5 mm to 30 mm, for example, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, or 30 mm. By controlling the protrusion structure of the stopper within a certain protrusion height range, the fit clearance between the stopper and the second cabinet 14 can be reduced while ensuring the strength of the stopper itself, thereby preventing the stopper from easily deforming or damaging.

[0050] In some embodiments, there may be multiple first limiting members 15 and multiple second limiting members 16 , and the multiple first limiting members 15 and the multiple second limiting members 16 are all arranged in sequence along the first direction.

[0051] A plurality of different limiting members are arranged at intervals on both sides of the second cabinet 14. A plurality of first limiting members 15 can play a limiting role on one side of the second cabinet 14, and a plurality of second limiting members 16 can play a limiting role on the other side of the second cabinet 14. By increasing the number of limiting members, it is possible to ensure that the second cabinet 14 is limited in a larger area, effectively ensuring the stability of the second cabinet 14 when it is matched with the first cabinet 11. Figure 7 As shown, multiple first limiting members 15 and multiple second limiting members 16 can be respectively provided corresponding to the top area, the middle area, and the bottom area of ​​the first accommodating space 101, thereby respectively playing a limiting role in different areas of the first accommodating space 101. In different areas of the first accommodating space 101, two or more limiting members can be grouped together to play a limiting role in more locations and reduce the difficulty of cooperation with the second cabinet 14.

[0052] In actual situations, in order to facilitate the exposure of the second cabinet 14, the side where the first limiting member 15 or the second limiting member 16 is located can be set as a movable structure, so that the second cabinet 14 located in the first accommodating space 101 can be exposed by moving the side wall of the cabinet. For example, when a cabinet door is set on the front side of the second cabinet 14, a movable cabinet side wall can be set on the side where the cabinet is locked, so that the cabinet side wall can be moved so that the cabinet side wall and the limiting member located on the cabinet side wall are moved away from the second cabinet 14, thereby avoiding the installation or removal of the second cabinet 14.

[0053] In some embodiments, the cabinet matching structure may further include a connecting assembly, which includes a first connecting member 17 and a second connecting member 18 spaced apart in a first direction, and the first connecting member 17 and the second connecting member 18 both connect the first cabinet 11 and the second cabinet 14 .

[0054] After the first cabinet 11 and the second cabinet 14 are mated, the connecting assembly can be used to secure the first cabinet 11 and the second cabinet 14, connecting the first cabinet 11 and the second cabinet 14 into a single unit. The first connector 17 and the second connector 18 can connect different cabinets at different locations along the first direction, ensuring a secure connection between the cabinets. In practice, two or more connectors can be provided in the same direction to connect different cabinets.

[0055] like Figure 11 As shown, the first connecting member 17 can be provided with a first mounting hole 171 and a second mounting hole 172 located on the same plane, the first mounting hole 171 is used for the first fastener to pass through and connect to the first cabinet 11, and the second mounting hole 172 is used for the second fastener to pass through and connect to the second cabinet 14.

[0056] The first connector 17 can be configured in a plate shape, with the first mounting hole 171 and the second mounting hole 172 located at different positions on the first connector 17. Both the first mounting hole 171 and the second mounting hole 172 can be passed through by fasteners, so that the first connector 17 uses multiple fasteners to connect the first cabinet 11 and the second cabinet 14. By arranging the different mounting holes on the first connector 17 on the same plane, the structure of the first connector 17 can be simplified, thereby reducing the difficulty of connecting the first connector 17.

[0057] like Figure 12 As shown, the second connecting member 18 may include a first fitting portion 181 and a second fitting portion 182 connected to each other, the first fitting portion 181 abuts against the first cabinet 11 and is connected to the first cabinet 11, and the second fitting portion 182 abuts against the second cabinet 14 and is connected to the second cabinet 14.

[0058] The first fitting portion 181 and the second fitting portion 182 are located at different positions of the second connector 18 and are used to form a connection relationship with different cabinets. By connecting the fitting portions with different cabinets, the matching area between the different cabinets can be ensured, thereby ensuring the stability of the connection. The different fitting portions can all be configured in a plate shape, and the connection between the different fitting portions can adopt an acute angle, a right angle, or an obtuse angle as the transition. The different fitting portions can adopt an integrally molded structure to ensure the structural strength of the second connector 18.

[0059] In addition, the second connecting member 18 may further include an enclosing portion 183 , which is connected to the first fitting portion 181 and encloses the first fitting portion 181 to form a hollow area 184 .

[0060] The enclosing portion 183 is connected to the first fitting portion 181 and is configured to have multiple bends or a continuous bend. The hollow area 184 formed between the enclosing portion 183 and the first fitting portion 181 can be used to form a handle on the enclosing portion 183 to apply tension to the second cabinet 14 during transportation.

[0061] like Figure 12 As shown, the first fitting portion 181 and the second fitting portion 182 of the second connector 18 are arranged perpendicularly, and the through holes on the first fitting portion 181 and the through holes on the second fitting portion 182 are staggered. The enclosing portion 183 includes an extension portion and two connecting portions arranged opposite to the extension portion, with the ends of the two connecting portions away from the extension portion connected to the second fitting portion 182. The extension portion and the second fitting portion 182 remain parallel, and the connecting portions are arranged perpendicularly between the extension portion and the second fitting portion 182, together enclosing a hollow area 184, allowing the enclosing portion 183 to be used as a handle.

[0062] The cabinet matching structure provided in some embodiments of the present application eliminates the original guide rail pull-out matching structure of the uninterruptible power supply, and forms a rear-end closed plug hole 142 at the bottom through two bottom brackets, namely the plug-in component 141. The rear-end closure can avoid damage to the wiring harness, and reinforcing ribs and other structures can also be set on the bottom bracket.

[0063] The connecting assembly can include four connecting parts, which are connected to the columns of the cabinet. The upper two connecting parts only serve as a connection, and the lower two connecting parts are also provided with handles. The bolts that serve as a tightening function can be hidden in the handles. Sensors, buttons and other components can also be set.

[0064] On the left and right sides of the first cabinet 11 are two sets of brackets, namely the first support member 12 and the second support member 13. The triangular structure of the bracket can enhance the supporting strength. The bracket is provided with limit members for limiting the left and right sides of the cabinet of the uninterruptible power supply. The bracket and the limit member can also be provided with wire holes 126 and tie holes 127. Other structures can also be used to replace the function of the wire holes 126.

[0065] like Figures 1 to 5 As shown, the bottom of the uninterruptible power supply cabinet is provided with two hollow bottom brackets, and the two bottom brackets are used for inserting two forks of a forklift to move the uninterruptible power supply located above the first cabinet 11 through the two bottom brackets. When replacing the uninterruptible power supply, considering that it is too heavy to be carried manually, a mechanical forklift can be used to fork out the uninterruptible power supply as a whole. Figure 4 and Figure 5 As shown, the rear ends of the two bottom brackets are closed to avoid damage to the wiring harness located behind the bottom brackets, and structures such as reinforcing ribs can also be processed on the bottom brackets.

[0066] like Figure 1 and Figure 3 As shown, four connectors are connected to the columns of the cabinet body. The two upper connectors only connect the cabinet body of the uninterruptible power supply and the cabinet body of the integrated cabinet. In addition to connecting the cabinet body of the uninterruptible power supply and the cabinet body of the integrated cabinet, the two lower connectors are also provided with handles to assist in pulling the uninterruptible power supply outward by a forklift. The bolt holes of the lower connectors can be hidden in the handles, and sensors, buttons and other components can also be provided on the connectors.

[0067] like Figures 7 to 9 As shown, two brackets, i.e., support members, are provided on the left and right sides of the cabinet. The bracket includes a first extension 124, a first plate 121, a second plate 122, and a second extension 125 connected in sequence from top to bottom. The first extension 124 is perpendicular to the first plate 121, and the angle between the first plate 121 and the second plate 122 is an acute angle to enhance the support strength of the uninterruptible power supply. The first extension 124 and the second extension 125 are parallel. Figure 9As shown, the bracket is further provided with a wire hole 126 and a tie hole 127 , and the function of the tie hole 127 can be replaced by other structures.

[0068] like Figure 7 As shown, two groups of limit plates are provided on the left and right sides of the cabinet, that is, plate-shaped limit members to limit the left and right directions of the uninterruptible power supply. Each group of limit plates includes a plurality of limit plates arranged on the side panels of the cabinet in sequence from top to bottom, and at least one limit plate in each group of limit plates is located on the first plate body 121 of the support member.

[0069] In addition, if Figure 13 As shown, a controller 111 can be provided on the front side of the second cabinet 14 to play a control role, and the controller 111 can be integrated on the cabinet door. In actual circumstances, cabinet panels or cabinet doors can be provided on different sides of the first cabinet 11 to seal different accommodation spaces to isolate them from the influence of the external environment.

[0070] Some embodiments of the present application further provide an integrated cabinet comprising the aforementioned cabinet assembly structure, an uninterruptible power supply (UPS), a power distribution assembly, and a busbar assembly. The UPS is disposed within the second cabinet. The power distribution assembly is disposed within the power distribution assembly area of ​​the first cabinet. The busbar assembly is disposed within the busbar assembly area of ​​the first cabinet.

[0071] The DC busbar assembly connects to the high-voltage box of the battery cluster inside the container, which in turn outputs DC power to the energy storage converter via the AC / DC distribution assembly. The AC / DC distribution assembly also outputs AC power, connecting it to an external power source and the electrical devices inside the container. The AC / DC distribution assembly consists of an AC control section and a DC distribution section. The AC control section connects to the external power source and the electrical devices inside the container, while the DC distribution section connects to the energy storage converter.

[0072] The integrated cabinet integrates the AC control and DC power distribution components, saving space in the container's width when installed. Furthermore, the DC busbar assembly is located to one side of the AC / DC power distribution components, further saving space in the container's width.

[0073] Some embodiments of the present application also provide an energy storage system, which includes the above-mentioned integrated cabinet.

[0074] The energy storage system includes a container body, which is equipped with a liquid cooling unit. The integrated cabinet is installed in the container body and is arranged side by side with the liquid cooling unit in the width direction of the container body. The integrated cabinet integrates the AC control part and the DC power distribution part to meet the electrical control requirements. When the integrated cabinet and the liquid cooling unit are placed side by side in the container body, the space in the width direction of the container body is saved. In addition, the DC bus assembly is located to one side of the AC and DC power distribution assembly, making the integrated cabinet more compact in its own width direction, further saving space in the width direction of the container body, thereby facilitating the liquid cooling unit to increase the upper limit of the design size, and thus facilitating the improvement of the battery energy density in the container body.

[0075] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present application, and that in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
