[0041] Example 1

[0042] To save space and facilitate operation and maintenance, please refer to... Figure 1 , Figure 3 , Figure 4 , Figure 7 This embodiment provides an industrial and commercial energy storage cabinet, including a cabinet body 1, wherein a first space 2 and a second space 3 are provided inside the cabinet body 1 from top to bottom;

[0043] The second space 3 has an equipment room 4 located on the side near the rear panel of the cabinet 1. The equipment room 4 has a vertical partition 41 and a first supporting horizontal plate 42. The vertical partition 41 divides the equipment room 4 into two storage spaces along the width of the cabinet 1 for storing electrical equipment.

[0044] One end of the first support horizontal plate 42 is fixed to the vertical partition plate 41, and the other end of the first support horizontal plate 42 is fixed to the support beam 11 inside the cabinet 1; the first support horizontal plate 42 divides the storage space into upper and lower layers to separate the storage of electrical equipment, with a high degree of integration.

[0045] For example, the first space 2 and the second space 3 are separated by a partition 5, which supports the equipment to be placed in the first space 2, such as a battery box 21. To enhance the load-bearing capacity, a support rod 43 is provided at the lower part of the first support plate 42.

[0046] For example, the bottom of the cabinet 1 is bolted to the foundation, which can support the relocation of the entire machine within 1 hour. To facilitate heat dissipation, heat dissipation structures, such as radiators and heat dissipation perforated plates, are provided on the front and rear panels of the cabinet; more specifically, the heat dissipation structures are located at the bottom of the front and rear panels.

[0047] In the specific implementation process, see Figure 4 , Figure 5 Along the length of the second space 3, a third space 6, an equipment room 4, and a fourth space 7 are sequentially arranged. The bottoms of the third space 6, the fourth space 7, and the equipment room 4 are all separated by partitions 44, and the upper parts of the third space 6, the equipment room 4, and the fourth space 7 are connected. For example, the third space 6 and the fourth space 7 are located at the front and rear sides of the cabinet 1, respectively. A floor drain 61 is provided at the bottom of the third space 6 so that leaks inside the cabinet 1 can flow out of the cabinet 1 through the floor drain 61, preventing leaks from accumulating inside the cabinet 1. The fourth space 7 can be used to organize the cables of each device in the second space 3 and connect them to the cables outside the cabinet 1, which facilitates operation, maintenance, reduces the workload of staff, and improves work efficiency.

[0048] To improve stability, see Figure 5 The upper part of the fourth space 7 is also provided with a support member 71. The support member 71 can be a frame type, and the bottom of the frame type is provided with a second support plate 711 that is parallel to the first support plate 42 and has the same height, so that the first support plate 42 and the second support plate 711 can be used to support a device at the same time, such as a liquid cooling unit.

[0049] In the specific implementation process, see Figure 4 , Figure 8The cabinet 1 has a first cable tray 12 on its support beam 11, and the first cable tray 12 is located on one side of the third space 6, so that some of the wires in the cabinet 1 pass through the first cable tray 12, thereby improving the integration of the cabinet 1 and facilitating maintenance. It should be noted that the support beam 11 is set along the height direction of the cabinet 1 and is set on both sides of the length direction of the cabinet 1. The two ends of the support beam 11 abut against the bottom plate 13 and the top plate 14 of the cabinet 1, respectively. On the one hand, it supports the entire cabinet 1, and on the other hand, it can suspend small devices, such as protectors and switches, thereby improving the integration of the devices in the cabinet 1, reducing the size of the cabinet 1, and reducing the floor space occupied.

[0050] It should be noted that: the equipment room 4 is provided with a second cable tray 45, and the second cable tray 45 is located in the storage space where the first support plate 42 is located, so that the cables in the equipment room 4 can pass through the second cable tray 45, making the area planning inside the cabinet 1 more reasonable. Furthermore, in order to plan the space inside the cabinet 1 more reasonably, the second cable tray 45 is arranged parallel to the length direction of the cabinet 1, and the second cable tray 45 and the first cable tray 12 are located on the same side of the cabinet 1.

[0051] In the specific implementation process, see Figure 6 The cabinet 1 has reinforcing ribs 131 on its outer surface of the bottom plate 13, and the reinforcing ribs 131 have clearance openings 132. The bottom plate 13 has through holes 133 through which the wiring harness of the equipment room 4 enters the bottom of the cabinet 1 and then passes through the clearance openings 132. Thus, the reinforcing ribs 131 are located at the bottom of the cabinet 1. This design ensures that forklifts will not damage the cables at the bottom of the cabinet 1 during transport, improving the safety and stability of the cabinet 1. It should be noted that several clearance openings 132 can be provided, and specific clearance openings 132 for connecting cables can be selected according to actual needs. To facilitate the movement of the cabinet 1, clearance openings 132 are also provided along the circumference of the bottom of the cabinet 1, allowing cables to exit through these clearance openings and avoid contact with the ground.

[0052] In the specific implementation process, see Figure 1 , Figure 2The second space 2 contains at least two battery boxes 21 arranged from top to bottom. One storage space contains a high-voltage box 31, and the other storage space contains a liquid-cooled unit 32 and an energy storage converter 33. The liquid-cooled unit 32 and the energy storage converter 33 are located above and below the first supporting horizontal plate 42, respectively. The cables of the energy storage converter 33 enter the fourth space 7 through the second cable tray 45, and then exit the cabinet 1 through the through hole 133 and connect to external equipment via the clearance opening 132. This layout is compatible with energy storage converters 33 from various manufacturers, allowing for flexible adjustments. The cabinet 1 design achieves N+1 flexible expansion through bus parallel technology, with a maximum single system expansion to 1MW / 2MWh, meeting the incremental investment needs of industrial and commercial users.

[0053] For example, several support plates (not labeled in the figure) are symmetrically arranged on both sides of the width direction in the first space 2 to support the battery box 21;

[0054] The high-voltage box 31 integrates a DC circuit breaker 311 and an AC circuit breaker 312, greatly reducing installation and wiring operations. For example, the dimensions of the cabinet 1 can be 1150×1335×2230mm (width, length, and height, respectively), which occupies a small area and has a high space utilization rate.

[0055] The effects of this utility model are at least:

[0056] 1. The structural design, with the upper part serving as the battery compartment and the lower part as the electrical compartment, achieves physical isolation between strong and weak currents, shortening cable routing paths by more than 30%, significantly reducing installation complexity, and improving equipment disassembly and maintenance efficiency by 40%.

[0057] 2. The vertical stacking layout of the cabinets reduces the floor space to 1.53㎡, making them particularly suitable for space-sensitive scenarios such as industrial and commercial sites and underground parking lots;

[0058] 3. The integrated design of functional zones in the second space reduces operation and maintenance time to 1 / 3 of that of the traditional structure;

[0059] 4. This structural design reduces equipment maintenance costs by more than 25%, and the improved site adaptability reduces site selection costs by 30%; the modular design extends the equipment lifespan to 15 years, and the LCOE (Levelized Cost of Electricity) is 18.6% lower than the traditional solution.
