[0038] Please refer to the following: Figure 1 and Figure 2 The cabinet provided in this application embodiment will now be described. The cabinet includes multiple cabinets 100, which are detachably connected sequentially along the length of the cabinet. Each cabinet 100 includes a top frame 110, a main frame 120, and a base frame 130 connected sequentially along the height of the cabinet. Each cabinet 100 has multiple connection points 140 distributed on the top frame 110, main frame 120, and base frame 130. The connection points 140 are used for detachable connection between adjacent cabinets 100. A connector is provided at the connection point between adjacent cabinets 100, with one part of the connector connected to one cabinet 100 and the other part connected to the other cabinet 100.

[0039] Compared with the prior art, the cabinet provided in this application can be disassembled into multiple cabinets 100, each of which is transported separately and then assembled at the designated location. This solves the transportation and installation problems caused by the excessive size of traditional large cabinets. Multiple connection points 140 are distributed on the top frame 110, the main frame 120, and the base frame 130, which can fix adjacent cabinets 100 in all directions from the top, middle, and bottom, ensuring the stability and uniformity of the connection. By setting connectors, the connection strength between adjacent cabinets 100 can be further strengthened, ensuring the structural stability and seismic resistance of the cabinet after disassembly and reassembly.

[0040] This application uses a two-cabinet setup as an example. The cabinet includes a first cabinet and a second cabinet. The first cabinet is a modular double-door cabinet, containing ten PM100D power modules, two bypass modules, one monitoring module, one main circuit switch, and multiple first conductive bars. The second cabinet is a switch single-door cabinet, containing a bypass switch, a bypass maintenance switch, an output switch, and multiple second conductive bars. The first and second conductive bars are one-to-one, with one first conductive bar connected to one second conductive bar. The first cabinet includes a first top frame, a first main frame, and a first base frame; the second cabinet includes a second top frame, a second main frame, and a second base frame. The first and second top frames are bolted together; the first and second main frames are bolted together; and the first and second base frames are bolted together. When conditions permit, the entire cabinet can be transported and installed directly. If the freight elevator is too small to fit, the cabinet can be disassembled into the first and second cabinets, transported in the elevator, and then reassembled into the cabinet at the designated location.

[0041] In one embodiment of this application, please refer to the following: Figure 4 and Figure 5 The connectors include a top connector 210 and a base connector. The top connector 210 is used to connect the top frames 110 of two adjacent cabinets 100; the base connector is used to connect the base frames 130 of two adjacent cabinets 100.

[0042] In this embodiment, by subdividing the connector into a top connector 210 and a base connector, targeted designs can be made for the different stress characteristics of the top and bottom of the cabinet 100, further improving the rationality of the connection structure. The top connector 210 can effectively constrain the relative displacement of adjacent cabinets 100 in the horizontal direction, preventing the cabinets 100 from becoming misaligned due to shaking during transportation or use; the base connector can enhance the overall load-bearing capacity and anti-overturning performance of the cabinet, ensuring that multiple cabinets 100 form a stable overall structure after assembly, maintaining good stability even when the ground is uneven or subjected to external impact.

[0043] In one embodiment of this application, please refer to the following: Figure 5 and Figure 6 The top connector 210 includes a connector body 211 and limiting portions 212 located at both ends of the connector body 211; the limiting portions 212 are perpendicular to the connector body 211; the connector body 211 is arranged along the length direction of the joint between the two cabinets 100, the two cabinets 100 are sandwiched between the two limiting portions 212, one end of the top connector 210 along its width direction is connected to one of the cabinets 100, and the other end of the top connector 210 along its width direction is connected to the other cabinet 100.

[0044] In this embodiment, the limiting part 212 can precisely limit the lateral position of two adjacent cabinets 100, preventing left and right offset of the cabinets 100 during the connection process and ensuring the alignment accuracy at the connection seam. The connector body 211 is arranged along the length of the connection seam, which can make the connection force evenly distributed along the longitudinal direction of the cabinet 100, reducing local stress concentration. At the same time, the two ends of the top connector 210 are connected to the two cabinets 100 respectively, forming a "bridge-type" connection structure, which can transmit lateral force and buffer longitudinal vibration to a certain extent, further improving the overall seismic performance of the cabinet.

[0045] In one embodiment of this application, please refer to the following: Figure 5 and Figure 7 The base connector includes a first connector 220, which is elongated and arranged perpendicular to the length of the joint between the two cabinets 100. One end of the first connector 220 along its length is connected to one of the cabinets 100, and the other end of the first connector 220 along its length is connected to the other cabinet 100.

[0046] In this embodiment, the first connector is positioned perpendicular to the joint, providing strong support in the lateral direction of the cabinet 100 and tightly "pulling" the two cabinets 100 together, effectively resisting the tendency of the cabinet to separate during horizontal vibration. Its design, with both ends connected to adjacent cabinets 100, allows the connection force to act directly on the base frame 130 of the cabinet 100, ensuring a short and efficient force transmission path and preventing deformation of the connection structure due to excessive lever arm. This layout also forms a cross-force system with the top connector 210, reinforcing the cabinet 100 connection from different directions and further improving the overall structural rigidity and torsional resistance of the cabinet.

[0047] In one embodiment of this application, please refer to the following: Figure 5 and Figure 7The base connector also includes a second connector 230, which includes a connecting part and an abutting part that are perpendicular to each other. The connecting part and the abutting part are integrally formed into an L-shaped second connector 230. The second connector 230 is located at the connection between the base frame 130 and the main frame 120. The connecting part is connected to the base frame 130, and the abutting part abuts against the main frame 120. When connecting two cabinets 100, the second connector 230 can be fixed to the base frame 130 of one of the cabinets 100 first. The other cabinet 100 can slide along the L-shaped second connector 230 to fit and fix itself to the first cabinet 100. Then, it is connected and fixed by the fasteners of the first connector 220. In this way, the two cabinets 100 can be connected quickly and accurately.

[0048] In this embodiment, the connection between the connecting part and the base frame 130 can be achieved through fasteners 142 such as bolts, ensuring a stable connection between the second connecting part 230 and the bottom structure of the cabinet 100. The abutment between the abutting part and the main frame 120 can distribute the vertical load transmitted by the main frame 120 to the base frame 130, forming an effective force transmission path and preventing the base frame 130 from deforming due to excessive local stress. This vertically distributed connecting part and abutting part structure enables the second connecting part 230 to have the dual functions of connection and load-bearing, which not only enhances the connection strength of adjacent cabinets 100 at the bottom, but also improves the overall compression resistance of the cabinet, ensuring that the bottom structure of the cabinet 100 remains stable and reliable during long-term use or when bearing heavy equipment.

[0049] In one embodiment of this application, please refer to the following: Figure 2 and Figure 3 The main frame 120 includes a crossbeam 121 and a longitudinal beam 122, which are connected to form a frame structure; multiple connection points 140 are distributed on the crossbeam 121 and the longitudinal beam 122.

[0050] In this embodiment, the intersecting frame structure formed by the horizontal beams 121 and the vertical beams 122 provides basic support for the cabinet 100. Through the connection with the horizontal beams 121 and the vertical beams 122, the stress originally concentrated at the edge of the frame is transferred inward, effectively improving the overall load-bearing capacity and deformation resistance of the main frame 120. The dispersed distribution of multiple connection points 140 on the horizontal beams 121 and the vertical beams 122 allows for multi-point alignment and fixation when adjacent cabinets 100 are connected. This not only enhances the strength of the connection but also ensures that the stress on each connection point 140 is uniform, avoiding the impact on the overall structural stability due to overload of local connection points 140.

[0051] In one embodiment of this application, a conductive busbar is also provided inside the cabinet 100, and a connection area is formed within the frame structure. The conductive busbar 123 is connected to the crossbeam 121 and / or the longitudinal beam 122 and is located within the connection area. Multiple connection points 140 are distributed on the conductive busbar 123, and the conductive busbars of two adjacent cabinets 100 are interconnected.

[0052] In this embodiment, the conductive busbar 123 is used to realize power transmission and distribution within the cabinet, connecting various functional modules (such as power modules, switch modules, etc.) into a complete electrical circuit. Placing the conductive busbar 123 within the connection area formed by the crossbeams 121 and longitudinal beams 122, and connecting it to the crossbeams 121 and / or longitudinal beams 122, also enhances the stability of the frame structure. Connection points 140 are distributed on the conductive busbar 123, allowing adjacent cabinets 100 to complete electrical connections simultaneously with mechanical connections, simplifying the assembly process, reducing the complexity of additional wiring, and improving the overall electrical performance stability of the cabinet.

[0053] Specifically, the conductive busbar 123 is made of copper or aluminum with high conductivity, which can effectively reduce resistance loss during current transmission and increase the structural strength of the main frame 120. The connection of the conductive busbars 123 of adjacent cabinets 100 can be achieved by bolt fastening or plug-in structure, which not only ensures the tightness of the connection to reduce contact resistance, but also facilitates quick docking during the assembly of cabinets 100.

[0054] In one embodiment of this application, please refer to the following: Figure 2 and Figure 3 The connection point 140 includes a mounting hole 141, and a fastener 142 is provided in the mounting hole 141. The fastener 142 is used to connect two adjacent cabinets 100 at the mounting hole 141.

[0055] In this embodiment, the design of the mounting hole 141 provides a precise positioning reference for the installation of the fastener 142, ensuring that adjacent cabinets 100 can be quickly aligned during connection, thus improving assembly efficiency. The fastener 142 can be made of high-strength bolts, screws, etc., and its cooperation with the mounting hole 141 forms a rigid connection, effectively transmitting tensile and shear forces between cabinets 100. During actual installation, the preload of the connection point 140 can be controlled by adjusting the tightening torque of the fastener 142, allowing multiple connection points 140 to form a cohesive whole, preventing individual connection points 140 from failing due to excessive force.

[0056] Please see Figure 1 , Figure 1A dashed circle in the diagram represents a connection point 140. A connection point 140 may include multiple mounting holes 141. These mounting holes 141 can be configured with different diameters and spacings according to actual connection requirements to accommodate fasteners 142 of different specifications, enhancing the versatility and flexibility of the connection structure. For example, when adjacent cabinets 100 need to transmit a large load, a high-strength bolt with a larger diameter can be used with mounting holes 141 of the corresponding diameter to ensure connection strength; while for parts with smaller loads, smaller fasteners 142 can be used, reducing costs while ensuring connection reliability. The distribution of multiple mounting holes 141 at the same connection point 140 also enables the cabinets 100 to be connected and fixed at multiple angles and directions, further improving the stability and tightness of the connection between adjacent cabinets 100, effectively preventing relative rotation or loosening of the cabinets 100 during use.

[0057] In one embodiment of this application, the top frame 110, the main frame 120, and the base frame 130 are all steel frame structures.

[0058] In this embodiment, the steel frame structure features high strength and rigidity, providing a solid load-bearing foundation for the cabinet and effectively resisting external impacts and vibration loads. The top frame 110, main frame 120, and base frame 130 are connected using an integral molding or welding process, ensuring the connection strength between the frames and preventing structural deformation or loosening under stress. The selection of steel can be optimized according to the load-bearing requirements and seismic resistance level of the cabinet. For example, using high-quality steel such as Q235 or Q345 ensures structural safety while controlling the overall weight, facilitating transportation and installation.

[0059] In one embodiment of this application, please refer to the following: Figure 4 and Figure 5 The cabinet 100 includes a cabinet door 150 and a door panel 160; the door panel 160 is connected to the main frame 120, one side of the cabinet door 150 is connected to the main frame 120 by a hinge, and the other side of the cabinet door 150 is fixed to the main frame 120 by a door lock.

[0060] In this embodiment, the door panel 160 can be fixedly installed or movably connected according to actual needs. Its connection to the main frame 120 can be achieved using bolts or welding, ensuring the structural stability of the door panel 160 and the cabinet 100, while providing protection and enclosed space for the equipment inside the cabinet. The cabinet door 150 is flexibly opened and closed via hinges, facilitating daily maintenance, inspection, and replacement of the UPS equipment inside the cabinet by operators. The door lock effectively ensures the security of the equipment inside the cabinet, preventing unauthorized personnel from arbitrarily opening the cabinet door 150 and avoiding the risk of accidental damage to the equipment or data leakage. The design of the cabinet door 150 and door panel 160 ensures the airtightness of the cabinet 100 to reduce the impact of external factors such as dust and moisture on the equipment, while also taking into account both operational convenience and safety.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
