Figures 1 to 3, including a bottom plate 1, side plates 11 are installed at both ends of the bottom plate 1, and a front plate 12 and a rear plate 13 are installed between the side plates 11. A number of heat dissipation holes 121 are provided on the front plate 12, and an identification layer 122 is sprayed on the side of the front plate 12 away from the rear plate 13. The heat dissipation holes 121 facilitate heat dissipation of components, and the identification layer 122 reflects the name label, which is convenient for staff to identify. A left partition 15 and a right partition 16 are installed between the bottom plate 1, the front plate 12 and the rear plate 13. The left partition 15 and the right partition 16 are both located between the side plates 11, and the left partition 15 and the right partition 16 are both arranged parallel to the side plates 11. A cover plate 14 is installed on the side plates 11, the front plate 12 and the rear plate 13, and the top wall of the left partition 15 and the top wall of the right partition 16 are both in contact with the top of the cover plate 14. The left partition 15 is on the side away from the right partition 16 as the DC chamber 5, and the right partition 16 is on the side away from the left partition 15 as the AC chamber 6. The converter chamber is located between the left partition 15 and the right partition 16. High-power components for connecting to the power grid are installed in the AC chamber 6, high-power components for connecting to the battery are installed in the DC chamber 5, and high-power components for bidirectional current conversion are installed in the converter chamber. The front panel 12 is provided with mounting holes 1 21, 22, 3, 4, 24, and 5 25. A removable plug-in box 3 is installed in each of the mounting holes 1 21, 22, 3, 4, 24, and 5 25. The plug-in box 3 is made of metal. A status indicator light 31 and a debugging communication interface 32 are provided on the front side of the plug-in box 3. An isolation component 4 is provided on the rear side of the plug-in box 3. The isolation component 4 is used to isolate electromagnetic interference. The low-power components used for reliable operation management of equipment fire protection in the microgrid battery energy storage 5S comprehensive device are installed in the plug-in box 3 in the installation hole one 21, the low-power components used for safe and economical operation management of the energy storage battery in the microgrid battery energy storage 5S comprehensive device are installed in the plug-in box 3 in the installation hole two 22, the low-power components used for converting the grid AC power into DC power and the battery DC power into AC power in the microgrid battery energy storage 5S comprehensive device are installed in the plug-in box 3 in the installation hole three 23, the low-power components used for safe and reliable operation management of the AC distribution power supply and the DC working power supply in the microgrid battery energy storage 5S comprehensive device are installed in the plug-in box 3 in the installation hole four 24, and the low-power components used for safe and economical operation management of the energy storage battery charging and discharging energy, the equipment storage and generation energy, and the distribution and supply energy in the microgrid battery energy storage 5S comprehensive device are installed in the plug-in box 3 in the installation hole five 25. The right partition 16 and the left partition 15 separate the converter chamber 6, the DC chamber 5 and the converter chamber 7. The right partition 16 and the left partition 15 play the role of heat insulation and electromagnetic interference isolation, thereby reducing the mutual interference between high-power components.While reducing the distance between high-power and low-power components, plug-in box 3 isolates them, and isolation assembly 4 reduces electromagnetic interference with the components within plug-in box 3. This allows the components within the microgrid battery energy storage 5S integrated device to be distributed according to their function, simplifying the wiring between components. If any functional module fails, the corresponding plug-in box 3 can be directly disassembled and replaced, eliminating the need to individually identify components and wiring cables. This facilitates maintenance of the microgrid battery energy storage 5S integrated device and improves its operation and maintenance efficiency.

[0035] In order to support and limit the plug box 3, refer to Figures 1 to 5 A guide sleeve 8 is installed within mounting holes 1 21, 22, 3, 4, 24, and 5 25. The guide sleeve 8 is mounted on the plug-in box 3, with the inner wall of the guide sleeve 8 abutting against the outer wall of the plug-in box 3. A guide opening 81 is defined at the front of the guide sleeve 8 for inserting the plug-in box 3. The isolation assembly 4 is installed behind the guide sleeve 8. A set of fastening bases 832 are symmetrically mounted on the plug-in box 3. These fastening bases 832 define fastening holes 833, each of which contains fastening bolts 83, each of which is fitted with a gasket 831. A set of fastening nuts 82 are installed at the front of the guide sleeve 8. The fastening nuts 82 are threadedly engaged with the fastening bolts 83, which are used to abut the gasket 831 against the fastening nuts 82. Because the cross-section of the guide opening 81 is larger than that of the guide sleeve 8, insertion of the plug-in box 3 into the guide sleeve 8 is facilitated. After the plug-in box 3 is inserted into the guide housing 8, the fastening bolt 83 is threadedly connected to the fastening nut 82, so that the fastening bolt 83 abuts the gasket 831 against the fastening nut 82, thereby fixing the plug-in box 3 to the guide housing 8. When the plug-in box 3 is removed, the fastening bolt 83 is loosened to separate the fastening bolt 83 from the fastening nut 82. When the plug-in box 3 is installed in the guide housing 8, the guide housing 8 supports and limits the plug-in box 3, reducing the possibility of shaking of the plug-in box 3.

[0036] In order to reduce the electromagnetic interference of high-power components to low-power components, refer to Figures 1 to 4The isolation assembly 4 includes an isolation plate 41 and an anti-electromagnetic interference ring 42. The isolation plate 41 is installed on the rear side of the guide sleeve 8, and the anti-electromagnetic interference ring 42 is installed on the isolation plate 41. The anti-electromagnetic interference ring 42 is located outside the guide sleeve 8. An electrical socket 43 is installed on the isolation plate 41, and the electrical socket 43 is located inside the guide sleeve 8. The cables on the electrical socket 43 pass through the anti-electromagnetic interference ring 42 and are connected to the high-power components. An electrical plug connector 33 is installed on the rear side of the plug box 3, and the electrical plug connector 33 is plugged into the electrical socket 43. When the plug box 3 is inserted into the guide sleeve 8, the electrical plug connector 33 is plugged into the electrical socket 43, so that the low-power components in the plug box 3 are electrically connected to the high-power components through the electrical plug connector 33 and the electrical socket 43. The anti-electromagnetic interference ring 42 is sleeved on the connecting line to isolate electromagnetics and reduce the electromagnetic interference of high-power components on low-power components.

[0037] To reduce the possibility of connecting lines crossing each other, refer to Figures 1 to 3 , mounting hole 1 21 and mounting hole 2 22 are both connected to the DC chamber 5, mounting hole 3 23 is connected to the converter chamber 7, and mounting hole 4 24 and mounting hole 5 25 are both connected to the AC chamber 6. An AC port 61 is provided on the front panel 12, and the AC port 61 is interconnected with the AC chamber 6, and the AC port 61 is located between mounting hole 4 24 and mounting hole 5 25. A DC port 51 is provided on the front panel 12, and the DC port 51 is interconnected with the DC chamber 5, and the DC port 51 is located between mounting hole 1 21 and mounting hole 2 22. The operating handle of the DC circuit breaker in the DC circuit extends from the DC port 51, and mounting hole 1 21 and mounting hole 2 22 are distributed on both sides of the DC port 51, so that the battery management module and the fire management module are distributed on both sides of the DC high-power components, making it easier for the battery management module and the fire management module to be connected to the DC high-power components, while shortening the wiring length between the fire management module, the battery management module and the DC circuit. The AC circuit breaker operating handle in the AC circuit extends from the AC port 61. Mounting holes 4 24 and 5 25 are located on both sides of the AC port 61, allowing the power management module and the power management module to be located on both sides of the AC high-power components. This facilitates the connection of the power management module and the power management module to the AC high-power components, while also shortening the wiring length between the power management module, the power management module, and the AC circuit. Mounting hole 3 23 is located on one side of the converter chamber 7, facilitating the connection of the bidirectional converter module to the high-power components in the converter circuit and shortening the wiring length between the bidirectional converter module and the converter circuit. The converter chamber 7 is located between the DC chamber 5 and the AC chamber 6, facilitating the connection of DC high-power components and AC high-power components to the converter high-power components. By optimizing the layout of components, the interlacing of connecting wires is reduced, making it easier to identify connecting cables between components, and thus facilitating disassembly and replacement by staff, thereby facilitating maintenance of the microgrid battery energy storage 5S integrated device and improving the operation and maintenance efficiency of the microgrid battery energy storage 5S integrated device.

[0038] In order to facilitate the installation of high-power components, refer to Figures 1 to 3 The spacing between the second mounting hole 22 and the fourth mounting hole 24 is greater than 40% of the width of the front plate 12, facilitating installation of high-power components for bidirectional conversion within the converter chamber 7. The first mounting hole 21 and the fifth mounting hole 25 are located close to both sides of the front plate 12. The spacing between the first mounting hole 21 and the second mounting hole 22 is approximately 20% of the width of the front plate 12, facilitating installation of high-power DC components between the battery management module and the fire management module. The spacing between the fourth mounting hole 24 and the fifth mounting hole 25 is approximately 20% of the width of the front plate 12, facilitating installation of high-power AC components between the power management module and the energy management module.

[0039] The implementation principle of a 5S integrated microgrid battery energy storage device that is easy to operate and maintain in an embodiment of the present application is as follows: the converter chamber is located between the DC chamber 5 and the AC chamber 6, facilitating the connection of DC high-power components and AC high-power components to the converter high-power components. The low-power components in the battery management module and the low-power components in the fire management module are distributed on both sides of the DC high-power components, facilitating the connection of the battery management module and the fire management module to the DC high-power components, while also shortening the wiring length between the fire management module, the battery management module, and the DC circuit. The low-power components in the power management module and the low-power components in the electric energy management module are distributed on both sides of the AC high-power components, facilitating the connection of the power management module and the electric energy management module to the AC high-power components, while also shortening the wiring length between the power management module, the electric energy management module, and the AC circuit. The low-power components in the bidirectional converter module are installed in the converter chamber, facilitating the connection of the bidirectional converter module to the high-power components in the converter circuit, shortening the wiring length between the bidirectional converter module and the converter circuit. By optimizing the layout of components, the intertwining of connecting wires is reduced, making it easier to identify the connecting cables between components and facilitating removal and replacement by staff. The right partition 16 and the left partition 15 separate the converter chamber, the DC chamber 5, and the converter chamber 7. The right partition 16 and the left partition 15 provide thermal insulation and electromagnetic interference isolation, reducing mutual interference between high-power components. While reducing the distance between high-power and low-power components, the plug-in box 3 isolates the low-power components from the high-power components. The isolation assembly 4 weakens electromagnetic interference on the components within the plug-in box 3, thereby distributing the components in the microgrid battery energy storage 5S integrated device according to function and improving the neatness of the wiring between components. When any functional module fails, the corresponding plug-in box 3 is directly disassembled and replaced, reducing the need to individually identify components and wiring cables, facilitating maintenance of the microgrid battery energy storage 5S integrated device and improving the operation and maintenance efficiency of the microgrid battery energy storage 5S integrated device.
