[0045] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and in combination with the embodiments.

[0046] In one embodiment, as Figures 1 to 4 shown, a busbar cabinet body structure is provided, including a housing 10 and a first support member 20. The housing 10 is provided with a first accommodation cavity 110 and a second accommodation cavity 120. The second accommodation cavity 120 is provided above the first accommodation cavity 110. The first accommodation cavity 110 is used to accommodate a DC component 80. The DC component 80 includes a conductive busbar group 820, and the conductive busbar group 820 is used to connect a first wire harness 90. The second accommodation cavity 120 is used to accommodate a first AC component and a communication component 50. The distance from the conductive busbar group 820 to the bottom surface of the housing 10 is between 200 millimeters and 800 millimeters.

[0047] Among them, the overall shape of the housing 10 can be a cuboid. The housing 10 may include several side plates. For example, the housing 10 may include a front panel, a rear panel, a left side plate, a right side plate, and a top. The front panel, the rear panel, the left side plate, the right side plate, and the top enclose to form an accommodation cavity, and the accommodation cavity can be divided into a first accommodation cavity 110 and a second accommodation cavity 120. It should be noted that the front panel can be used as the panel of the door body.

[0048] The first accommodation cavity 110 may be arranged adjacent to the bottom surface of the housing 10. A corresponding first bracket is arranged in the first accommodation cavity 110. The first bracket can be used to install or support the corresponding DC devices in the DC component 80, so as to realize accommodating the DC component 80 in the first accommodation cavity 110. The first bracket can also be used to strengthen the first accommodation cavity 110.

[0049] The DC component includes a conductive bar group, which can be composed of several conductive bars. The conductive bars can be copper bars and are installed on the first bracket in the first accommodation cavity. The conductive bars are used for electrically connecting the first wire harness. The first wire harness can be a power wire harness. For example, the first wire harness can be composed of several first cables. It should be noted that the first cables can be copper cables.

[0050] By arranging the first accommodation cavity 110 below the second accommodation cavity 120, arranging the conductive bar group in the first accommodation cavity, and setting the distance from the conductive bar group to the bottom surface of the housing to be between 200 mm and 800 mm, the DC component 80 is arranged adjacent to the lower part of the housing 10, with a large operating space, which is convenient for operators to assemble and repair the conductive bar group. In addition, when the first wire harness extends into the first accommodation cavity, there is enough space to bend in the first accommodation cavity to realize the electrical connection between the first wire harness and the conductive bar group, improving the convenience of disassembling and assembling the first wire harness.

[0051] The second accommodation cavity 120 is arranged above the first accommodation cavity 110. Corresponding second brackets are arranged in the second accommodation cavity 120. The second brackets can be used to install or support the corresponding AC components in the first AC component and the corresponding communication components in the communication component 50, so as to arrange the first AC component and the communication component 50 in the second accommodation cavity 120; the second brackets can also be used to strengthen the second accommodation cavity 120. Exemplarily, the first AC component and the communication component 50 are arranged at intervals in the second accommodation cavity 120, so that there is a certain distance between the first AC component and the communication component 50 to avoid signal interference and improve the reliability of communication control; in addition, through the partition setting of the first accommodation cavity 110 and the second accommodation cavity 120, the partition layout setting between the DC component 80, the first AC component and the communication component 50 is realized, thereby improving the power supply and communication reliability of the busbar cabinet.

[0052] In the above embodiments, the second accommodation cavity 120 of the housing 10 is disposed above the first accommodation cavity 110. The first accommodation cavity 110 is used to accommodate the DC component 80, and the DC component includes a conductive busbar group for connecting the first wire harness. The second accommodation cavity 120 is used to accommodate the first AC component and the communication component 50. The distance from the conductive busbar group to the bottom surface of the housing is between 200 mm and 800 mm, realizing a reasonable layout of the DC component 80, the first AC component, and the communication component 50. In this application, by disposing the first accommodation cavity 110 below the housing 10, the conductive busbar group is disposed in the first accommodation cavity, and the distance from the conductive busbar group to the bottom surface of the housing is between 200 mm and 800 mm, there is a large operating space, which facilitates the operator to assemble and repair the conductive busbar group. In addition, when the first wire harness extends into the first accommodation cavity, there is enough space to bend in the first accommodation cavity to realize the electrical connection between the first wire harness and the conductive busbar group. By providing the second accommodation cavity 120 on the first accommodation cavity 110, a partition setting for the DC component 80, the first AC component, and the communication component 50 is realized. Different types of devices have a certain distance in space, improving the power supply and communication reliability of the busbar cabinet, reducing the mutual interference between different types of devices, facilitating inspection, operation, and maintenance, and improving the maintainability of the busbar cabinet.

[0053] In one embodiment, the distance from the conductive busbar group 820 to the bottom surface of the housing 10 is between 400 mm and 600 mm, so as to make full use of the space inside the cabinet, so that there is enough operating space in the first accommodation cavity 110, facilitating the operator to extend the first wire harness 90 into the first accommodation cavity 110 and then bend the first wire harness 90 and connect it to the conductive busbar group 820, realizing the electrical connection between the first wire harness 90 and the conductive busbar group 820, and improving the convenience of assembling and repairing the conductive busbar group 820 and the first wire harness 90.

[0054] In one embodiment, at least one side surface of the housing 10 is provided with a first through hole for passing through the first wire harness 90 so that the first wire harness 90 is bent and connected to the conductive busbar group 820.

[0055] For example, the housing 10 can be a cuboid-shaped housing. The housing 10 includes a front side, a rear side, a left side, a right side, and a bottom surface. Then, a first through hole can be provided on at least one of the front side, the rear side, the left side, the right side, and the bottom surface, so that after the first wire harness 90 extends into the first through hole, it can be bent, and the bent first wire harness 90 can be connected to the conductive busbar group 820. It should be noted that the size of the first through hole can be determined according to the diameter of the first wire harness 90. Exemplarily, the size of the first through hole can be set to be slightly larger than the diameter of the first wire harness 90, to prevent dust and other foreign objects from entering the first accommodation cavity 110 due to the overly large first through hole, while ensuring the strength of the corresponding side of the housing 10. For example, the installation process of the first wire harness 90 can be as follows: the first wire harness 90 is extended into the first through hole on the corresponding side (such as the rear side or the bottom surface) of the housing 10. Based on the sufficient space size within the first accommodation cavity 110, the first wire harness 90 is bent within the first accommodation cavity 110, and the bent first wire harness 90 is connected to the conductive busbar group 820, so as to realize the electrical connection between the first wire harness 90 and the conductive busbar group 820.

[0056] In one embodiment, as Figure 2 shown, the conductive busbar group 820 includes at least two conductive busbars 822, and the first wire harness 90 includes at least two first cables 910; each first cable 910 passes through the first through hole, so that at least one first cable 910 is bent and connected to the corresponding conductive busbar 822.

[0057] Among them, the conductive busbar 822 is used to electrically connect the corresponding first cable 910. For example, the conductive busbars 822 can be arranged at intervals within the first accommodation cavity 110. The first through hole can be used for each first cable 910 to pass through, so that the corresponding first cable 910 can be bent after extending into the first through hole, and the bent first cable 910 can be connected to the corresponding conductive busbar 822. In one example, the diameter of the first cable 910 applied to the energy storage busbar cabinet is relatively large, and the material of the first cable 910 is relatively hard, making it difficult to bend by manpower. For example, the first cable 910 uses a YJV22 type cable (i.e., a copper core cable with steel tape armoring). After the first cable 910 extends into the first through hole, tools such as a pulley are usually needed to bend the first cable 910. Therefore, based on the sufficient space size provided within the first accommodation cavity 110, after the first cable 910 passes through the first through hole and enters the first accommodation cavity 110, the operator has sufficient space to use tools such as a pulley to bend the first cable 910, and the bent first cable 910 is connected to the conductive busbar 822, so as to realize the electrical connection between the first cable 910 and the corresponding conductive busbar 822, improving the convenience of the operator in assembling the conductive busbar 822 and the first cable 910.

[0058] In one embodiment, as Figure 3 、 Figure 6 andFigure 7 As shown, the second accommodation cavity 120 includes a first accommodation sub-cavity 122 and a second accommodation sub-cavity 124, and the first accommodation sub-cavity 122 and the second accommodation sub-cavity 124 are spaced apart; the first accommodation sub-cavity 122 is used to accommodate the first AC component, and the second accommodation sub-cavity 124 is used to accommodate the communication component 50.

[0059] The first accommodation sub-cavity 122 and the second accommodation sub-cavity 124 are spaced apart. The first accommodation sub-cavity 122 is used to accommodate the first AC component, and the second accommodation sub-cavity 124 is used to accommodate the communication component 50. Thus, the first AC component and the communication component 50 are spaced apart, avoiding signal interference of the first AC component on the communication component 50, rationally utilizing the space of the second accommodation cavity 120, and improving the reliability of communication at the same time. Exemplarily, the first accommodation sub-cavity 122 can be disposed adjacent to the first side surface of the housing 10, and the second accommodation sub-cavity 124 can be disposed adjacent to the front panel of the housing 10, facilitating the connection between the first AC component and the second AC component 70.

[0060] In one embodiment, as Figure 1 、 Figure 3 and Figure 7 shown, a first partition 30 is provided between the first accommodation cavity 110 and the second accommodation cavity 120; the communication component 50 includes a controller 510 and a terminal block 520; the second accommodation sub-cavity 124 includes a first communication installation area 1242 and a second communication installation area 1244; the first communication installation area 1242 is provided on the first partition 30, and the second communication installation area 1244 is provided on the second side surface of the housing 10, and the second side surface of the housing 10 is adjacent to the first side surface; the first communication installation area 1242 is used to install the controller 510, and the second communication installation area 1244 is used to install the terminal block 520.

[0061] Among them, the first partition 30 is provided inside the housing 10, and the accommodation cavity of the housing 10 can be divided into the first accommodation cavity 110 and the second accommodation cavity 120 by the first partition 30. The controller 510 can be a BMS (Battery Management System). The terminal block 520 can include a power supply terminal, a communication terminal, and a control terminal. The power supply terminal can be a 24-volt power supply terminal. The first side surface of the housing 10 can be the outer wall of the rear panel of the housing 10, and the second side surface of the housing 10 can be the inner wall of the left side panel or the right side panel of the housing 10.

[0062] By providing a first communication installation area 1242 on the first partition 30, the controller 510 is installed in the first communication installation area 1242, that is, the first partition 30 plays a supporting role for the controller 510. By providing a second communication installation area 1244 on the second side surface of the housing 10, the terminal block 520 is installed in the second communication installation area 1244, thereby effectively utilizing the space of the second accommodation sub-chamber 124 and facilitating the wiring of the terminal block 520. Exemplarily, the control board can be arranged in the first communication installation area 1242 by means of snap connection or screw connection, etc., and the terminal block 520 can be arranged in the second communication installation area 1244 by means of snap connection or screw connection, etc. The second communication installation area 1244 can be provided with corresponding brackets, and then the terminal block 520 can be arranged on the corresponding brackets of the second communication installation area 1244 by means of snap connection or screw connection, etc.

[0063] Exemplarily, the second communication installation area 1244 is arranged adjacent to the front panel of the housing 10, so that after the operator opens the front panel (or door body), the terminal block 520 can be disassembled and assembled.

[0064] In one embodiment, as Figure 1 、 Figure 3 and Figure 6 shown, the first accommodation sub-chamber 122 is provided with a first AC installation area 1222 and a second AC installation area 1224; the first AC component includes an AC device group 610 and at least two UPS modules 620; the first AC installation area 1222 is arranged on the first communication installation area 1242, and the first AC installation area 1222 is used for installing the AC device group 610; the second AC installation area 1224 is arranged adjacent to the first side surface of the housing 10, and the second AC installation area 1224 is used for installing at least one UPS module 620.

[0065] Among them, the AC device group 610 can include a main incoming line circuit breaker, a miniature circuit breaker, a second terminal block 520, an AC / DC module, an intermediate relay, a splitter, an AC surge protection circuit, etc. The second terminal block 520 can include a wiring copper bar, a terminal for connecting to a high-voltage box, a terminal for connecting to a fire-fighting device, and a terminal for connecting to a disconnector 810. The UPS module 620 can include a UPS host and a storage battery. It should be noted that the UPS host and the storage battery can be integrated modules; the UPS host and the storage battery can also be independent modules.

[0066] By arranging the first AC installation area 1222 on the first communication installation area 1242, the AC device group 610 is installed on the first AC installation area 1222, so that there is a spaced arrangement between the AC device group 610 and the controller 510; by arranging the second AC installation area 1224 adjacent to the first side of the housing 10, the second AC installation area 1224 is spaced from the first communication installation area 1242, and the second AC installation area 1224 is spaced from the second communication installation area 1244. At least one UPS module 620 is installed in the second AC installation area 1224, so that there is a spaced arrangement between the UPS module 620 and the controller 510 and the terminal block 520 respectively, realizing the partition setting of the first communication installation area 1242, the second communication installation area 1244, the first AC installation area 1222 and the second AC installation area 1224, and further realizing the partition setting between the first AC component and the communication component 50, facilitating the disassembly, installation and maintenance operations of the first AC component and the communication component 50 by the operator, and at the same time being able to avoid signal interference, improving the power supply and communication reliability of the busbar cabinet.

[0067] Exemplarily, the AC device group 610 can be arranged in the first AC installation area 1222 by means of snap connection or screw connection, etc., and the corresponding USP module can be arranged in the second AC installation area 1224 by means of snap connection or screw connection, etc. The first AC installation area 1222 can be provided with corresponding brackets, so that the AC device group 610 can be arranged on the corresponding brackets in the first AC installation area 1222 by means of snap connection or screw connection, etc.; the second AC installation area 1224 can be provided with corresponding brackets, so that the corresponding USP module can be arranged on the corresponding brackets in the second AC installation area 1224 by means of snap connection or screw connection, etc. In one example, the first AC installation area 1222 can also be provided with a detachable panel, and the detachable panel can be used to cover the first AC installation area 1222 to prevent the operator from accidentally touching the live AC devices. The detachable panel is provided with a window. For example, after the wiring of the AC device group 610 is completed, by covering the detachable panel, only the operation handle of the circuit breaker and the visible window of the surge protection circuit are left on the detachable panel, thereby improving the safety of the busbar cabinet.

[0068] In one embodiment, as Figure 1 、 Figure 4 and Figure 6 shown, the busbar cabinet body structure further includes a first support member 20, and the first support member 20 is arranged on the first side of the housing 10, and the first support member 20 is used to support the second AC component 70.

[0069] The first support member 20 can be used to support the second AC component 70. The size of the AC device in the second AC component 70 is larger than that of the AC device in the first AC component, and the weight of the AC device in the second AC component 70 is greater than that of the AC device in the first AC component.

[0070] The first support member 20 is disposed on the first side surface of the housing 10. The first support member 20 is located outside the accommodation cavity, that is, the first support member 20 is disposed outside the housing 10. Exemplarily, the first side surface of the housing 10 is the rear panel of the housing 10, that is, the first support member 20 can be disposed on the outer wall of the rear panel of the housing 10. By disposing the second AC component 70 on the first support member 20, the partitioned arrangement of the second AC component 70 with the DC component 80, the first AC component, and the communication component 50 is realized, signal interference is avoided, and at the same time, the space in the first accommodation cavity 110 or the second accommodation cavity 120 is not occupied. It is convenient for the operator to operate or disassemble and assemble the second AC component 70 from the first side surface of the housing 10, improving the disassembly and assembly convenience and reliability of the busbar cabinet.

[0072] Wherein, the second support member 40 can be used to support at least one UPS module 620, and the UPS module 620 can be disposed on the second support member 40 by means of snap connection or screw connection, etc. The second support member 40 can be disposed on the first side surface of the housing 10 by means of screw connection or welding, etc., and the second support member 40 is spaced apart from the first support member 20. The second support member 40 is disposed on the first side surface of the housing 10, and the second support member 40 is located outside the accommodation cavity, that is, the second support member 40 is disposed outside the housing 10. Exemplarily, the first side surface of the housing 10 is the rear panel of the housing 10, that is, the second support member 40 can be disposed on the outer wall of the rear panel of the housing 10. Since the size and weight of the UPS module 620 are relatively large, by disposing the UPS module 620 on the second support member 40, the partitioned arrangement of the UPS module 620 with the communication component 50 is realized, signal interference is avoided, and at the same time, the space in the second accommodation cavity 120 is not occupied, facilitating the operator to operate or disassemble and assemble the UPS module 620 from outside the housing 10, improving the disassembly and assembly convenience and reliability of the busbar cabinet.

[0075] Wherein, the first support member 20 can be arranged above the second support member 40. The first support member 20 can be used to support the transformer 710. Since the size and weight of the transformer 710 are relatively large, by arranging the transformer 710 on the first support member 20, the partition setting of the transformer 710 and the communication component 50 is realized, avoiding signal interference and at the same time avoiding occupying the space in the second accommodation cavity 120, facilitating the operator to disassemble, assemble or maintain the transformer 710 from the outside of the housing 10, and improving the disassembly and assembly convenience and reliability of the busbar cabinet.

[0076] Exemplarily, a first window is provided on the left side plate of the housing 10 or a second window is provided on the right side plate. A first detachable plate is provided on the first window, and a second detachable plate is provided on the second window; the first side surface of the housing 10 is the outer wall of the rear panel of the housing 10.

When the transformer 710 needs to be disassembled and assembled, the first detachable plate or the second detachable plate of the housing 10 can be removed, and then the disassembly and assembly operation of the transformer 710 can be conveniently performed.

[0077] In one embodiment, as Figure 4 、 Figure 5 and Figure 7 shown, the first accommodation cavity 110 is provided with a third accommodation sub-cavity 112 and a fourth accommodation sub-cavity 114; the DC component 80 includes a disconnector 810; the third accommodation sub-cavity 112 is located between the second accommodation cavity 120 and the fourth accommodation sub-cavity 114. The third accommodation sub-cavity 112 is used to accommodate the disconnector 810, and the fourth accommodation sub-cavity 114 is used to accommodate the busbar group 820.

[0078] Among them, the conductive busbar group 820 can be a copper busbar. The conductive busbar group 820 is used to connect the first wire harness, and the first cable is a DC wire harness. The disconnect switch 810 is connected to the conductive busbar group 820. The disconnect switch 810 can be used as a circuit breaker for the input power supply or as a disconnect switch 810 for the output load, so as to isolate the output of the electrical equipment from the load.

[0079] The fourth accommodation subchamber 114 is located at the lowermost position of the accommodation chamber of the housing 10. The fourth accommodation subchamber 114 is used to accommodate the conductive busbar group 820. Exemplarily, the fourth accommodation subchamber 114 is provided with corresponding brackets, and thus the conductive busbar group 820 can be arranged on the corresponding brackets of the fourth accommodation subchamber 114 by means of screwing or the like. The third accommodation subchamber 112 is arranged on the fourth accommodation subchamber 114. The third accommodation subchamber 112 is used to accommodate the disconnect switch 810. Exemplarily, the third accommodation subchamber 112 is provided with corresponding brackets, and thus the conductive busbar group 820 can be arranged on the corresponding brackets of the third accommodation subchamber 112 by means of screwing or the like.

[0080] By partitioning the first accommodation chamber 110 and the second accommodation chamber 120, the partitioned setting of the DC component 80 with the first AC component, the second AC component 70 and the communication component 50 is realized. Different types of devices have a certain distance in space, which improves the power supply and communication reliability of the busbar cabinet; reduces the mutual interference between different types of devices and is convenient for maintenance and operation; by partitioning the third accommodation subchamber 112 and the fourth accommodation subchamber 114, there is a large operating space, which is convenient for the operator to disassemble and assemble the DC cable; Exemplarily, the space size of the fourth accommodation subchamber 114 is larger than that of the third accommodation subchamber 112. For example, the distance between the conductive busbar group 820 and the bottom surface of the housing 10 is 600 mm, so as to ensure that there is enough operating space for the DC circuit, which is convenient for disassembling and assembling the DC cable and meets the bending radius requirements of the cable.

[0081] In one embodiment, as Figure 4 、 Figure 5 and Figure 7 shown, the fourth accommodation subchamber 114 is provided with a first DC installation area 1142 and a second DC installation area 1144; the DC component 80 further includes a surge protector 830; the first DC installation area 1142 is arranged adjacent to the third accommodation subchamber 112; the first DC installation area 1142 is used to install the conductive busbar group 820, and the second DC installation area 1144 is used to install the surge protector 830.

[0082] Among them, the surge protector 830 can be used to absorb the mutated surge voltage and play a role in overvoltage protection. The first DC installation area 1142 can be arranged below the third accommodation sub-cavity 112. The first DC installation area 1142 is spaced from the bottom surface of the housing 10 to ensure a certain distance between the first DC installation area 1142 and the bottom surface of the housing 10, thus facilitating the operator to wire. The second DC installation area 1144 can be arranged on the second side or the third side of the housing 10. The second side of the housing 10 is adjacent to the first side of the housing 10, and the third side of the housing 10 is adjacent to the first side of the housing 10. For example, the second side of the housing 10 can be the inner wall of the left side plate of the housing 10, and the third side of the housing 10 can be the inner wall of the right side plate of the housing 10. Exemplarily, the surge protector 830 can be arranged in the second DC installation area 1144 by means of snap connection or screw connection, etc., and the conductive busbar group 820 can be arranged in the first DC installation area 1142 by means of snap connection or screw connection, etc.

[0083] By arranging the first DC installation area 1142 adjacent to the third accommodation sub-cavity 112, arranging the second DC installation area 1144 on the second side or the third side of the housing 10, installing the conductive busbar group 820 in the first DC installation area 1142, and installing the surge protector 830 in the second DC installation area 1144, the partition setting of the first accommodation cavity 110 is realized, and further the partition setting between the surge protector 830 and the conductive busbar group 820 is realized, which facilitates the operator to disassemble, install and maintain the surge protector 830 and the conductive busbar group 820, and improves the disassembly and installation convenience of the DC components 80 of the busbar cabinet.

[0084] In one embodiment, the first DC installation area 1142 is spaced from the bottom surface of the housing 10.

[0085] Among them, the spacing distance between the first DC installation area 1142 and the bottom surface of the housing 10 can be determined according to the actual application scenario of the busbar cabinet. For example, the spacing distance between the first DC installation area 1142 and the bottom surface of the housing 10 can be set to 600 mm, that is, the distance between the conductive busbar group 820 and the bottom surface of the housing 10 is 600 mm, thereby ensuring sufficient DC loop operation space and facilitating wiring of the conductive busbar group 820 and disassembling and installing DC cables.

[0086] In one embodiment, as Figures 1 to 3 shown, there is also provided a busbar cabinet, including DC components, first AC components, communication components and the busbar cabinet body structure as described in any one of the above; the DC components, first AC components, and communication components are respectively arranged on the busbar cabinet body structure.

[0088] The housing is provided with a first accommodation cavity and a second accommodation cavity. The second accommodation cavity is arranged above the first accommodation cavity. The first accommodation cavity is used to accommodate the DC component, and the DC component includes a conductive busbar group for connecting the first wire harness. The second accommodation cavity is used to accommodate the first AC component and the communication component. The distance from the conductive busbar group to the bottom surface of the housing is between 200 mm and 800 mm, realizing a reasonable layout of the DC component, the first AC component, and the communication component.

[0089] In the above embodiment, by arranging the first accommodation cavity below the housing, the conductive busbar group is arranged in the first accommodation cavity, and the distance from the conductive busbar group to the bottom surface of the housing is between 200 mm and 800 mm, there is a large operating space, which is convenient for operators to assemble and repair the conductive busbar group. In addition, when the first wire harness extends into the first accommodation cavity, there is enough space to bend in the first accommodation cavity to realize the electrical connection between the first wire harness and the conductive busbar group. By arranging the second accommodation cavity on the first accommodation cavity, the partition setting of the DC component, the first AC component, and the communication component is realized. Different types of devices have a certain distance in space, improving the power supply and communication reliability of the busbar cabinet; reducing the mutual interference between different types of devices, facilitating maintenance and operation, and improving the maintainability of the busbar cabinet.

[0090] In one embodiment, an energy storage container is further provided, including a container body and the busbar cabinet as described above; the busbar cabinet is arranged in the container body.

[0091] Among them, the energy storage box body may include an electrical compartment, and the busbar cabinet may be arranged in the electrical compartment.

[0092] The specific description of the busbar cabinet can refer to the specific description of the busbar cabinet in the above embodiments, and will not be elaborated here.

[0093] In the above embodiment, through the partition setting of the internal space of the busbar cabinet body and the optimized layout setting of the DC component, the first AC component, and the communication component, the overall volume of the busbar cabinet body is reduced, and thus the space occupied by the energy storage box body can be reduced, facilitating the maintenance operation or disassembly and assembly of the busbar cabinet by operators.

[0094] It should be noted that the energy storage container may further include components such as battery modules. Specifically, the energy storage container may include more components than those described in the above embodiments, or combine certain components, or have different component arrangements.

[0095] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0096] The above-described embodiments only express several implementation manners of the present application.
