Description

Technical Field

[0001] This utility model relates generally to the technical field of energy storage equipment, and more specifically to an electrical compartment and an outdoor energy storage cabinet. Background Technology

[0002] In the early stages of energy storage outdoor cabinet development, their structural designs often adopted a left-right compartment layout to house the battery compartment and electrical compartment, respectively. This design provided ample layout space for the assembly of electrical equipment, facilitating the integration of electrical units with similar functional attributes, such as inverters, power distribution devices, communication devices, and battery management units, into a single space. This resulted in clear functional zoning, orderly electrical wiring paths, and improved system integration, maintainability, and overall aesthetics. However, with increasingly stringent requirements for cost control in energy storage systems and a continuous pursuit of higher energy density per unit volume, the current mainstream design has gradually shifted towards a single-door cabinet structure with vertically layered, compartmentalized sections. In this structural form, the usable space in the electrical compartment is significantly reduced, posing a serious challenge to space utilization.

[0003] Therefore, there is a need to provide an electrical compartment and an outdoor energy storage cabinet to at least partially solve the above problems. Utility Model Content

[0004] The present invention includes a series of simplified concepts, which will be further explained in detail in the detailed description section. This present invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the first aspect of this utility model provides an electrical compartment for an outdoor energy storage cabinet. The electrical compartment includes a floor plate, a first mounting assembly, a second mounting assembly, and a third mounting assembly. The first, second, and third mounting assemblies are all located above and connected to the floor plate.

[0006] The floor plate has a front end and a rear end that are opposite in a first horizontal direction along the electrical compartment;

[0007] The first mounting assembly includes a first support member adapted to support a high-voltage box, the first support member being spaced apart from the bottom plate of the electrical compartment along the vertical direction of the compartment to form a first accommodating space adapted to accommodate an inverter;

The second mounting assembly is adapted to mount a power distribution assembly and a first communication assembly.

[0010] According to the electrical compartment of the first aspect of this utility model, by arranging a first mounting assembly and a second mounting assembly along a second horizontal direction, the first mounting assembly houses a high-voltage box and an inverter, while the second mounting assembly is used to house power distribution components and a first communication component, which are smaller in size than the high-voltage box and inverter. This facilitates full utilization and improves space efficiency. Since the first mounting assembly can arrange the high-voltage box and inverter vertically, its horizontal space occupation is reduced, leaving more usable space for the second mounting assembly, and simultaneously improving vertical space utilization.

In addition, by arranging a third mounting assembly between the first mounting assembly and the first mounting plate to install an uninterruptible power supply, the structural compactness of the electrical compartment is improved.

[0084] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0085] In the early stages of energy storage outdoor cabinet development, the structural design often adopted a left-right compartment layout to house the battery compartment and electrical compartment, respectively for the battery pack and electrical equipment. This design provided ample layout space for the assembly of electrical equipment, facilitating the integration of electrical units with similar functional attributes, such as inverters, power distribution devices, communication devices, and battery management units, into a single space. This resulted in clear functional zoning, orderly electrical wiring paths, and improved system integration, maintainability, and overall aesthetics. However, with the increasing demands for cost control in energy storage systems and the continuous pursuit of higher energy density per unit volume, the current mainstream design has gradually shifted to a single-door cabinet structure with upper and lower layers and compartments. In this structural form, the usable space in the electrical compartment is significantly reduced, posing a serious challenge to space utilization. Especially after accommodating large-volume electrical equipment such as high-voltage boxes, the remaining usable space is divided into multiple irregular areas, leading to limited layout and mutual interference of other electrical equipment. This leads to problems such as cluttered internal layout of electrical equipment compartments, disordered cable laying, and mixed functional module areas. This not only increases the construction difficulty and error risk of integrated assembly, but also seriously affects the internal heat dissipation management, maintenance convenience, and overall appearance quality of the equipment, thus restricting the optimization and upgrading of products towards higher integration and lower cost.

[0086] To at least partially solve the above problems, this utility model provides an electrical compartment and an outdoor energy storage cabinet. See below for details. Figures 1 to 9 The examples shown provide a detailed description of the electrical compartment 110 and the outdoor energy storage cabinet 100 according to embodiments of the present invention.

[0087] See Figures 2 to 4An embodiment of this utility model provides an electrical compartment 110. The electrical compartment 110 is used in an outdoor energy storage cabinet 100. The electrical compartment 110 includes a floor plate 120, a first mounting assembly 130, a second mounting assembly 140, and a third mounting assembly 180. The first mounting assembly 130, the second mounting assembly 140, and the third mounting assembly 180 are all located above and connected to the floor plate 120. The floor plate 120 has a front end 121 and a rear end 122 opposite to each other along a first horizontal direction D1 of the electrical compartment 110. The first mounting assembly 130 includes a first support member 131. The first support member 131 is adapted to support a high-voltage box. The first support member 131 is spaced apart from the floor plate 120 along the vertical direction D3 of the electrical compartment 110 to form a first receiving space 137 suitable for accommodating an inverter. The second mounting assembly 140 is located on one side of the first mounting assembly 130 along a second horizontal direction D2 of the electrical compartment. The second horizontal direction D2 is perpendicular to the first horizontal direction D1. The second mounting assembly 140 is adapted to mount a power distribution assembly and a first communication assembly. The second mounting assembly 140 includes a first mounting plate 150 and a second mounting plate 170. The first mounting plate 150 is spaced apart from the first mounting assembly 130 along a second horizontal direction D2. The second mounting plate 170 is located on the side of the first mounting plate 150 facing the rear end 122. The second mounting plate 170 is connected to the first mounting plate 150 and the first mounting assembly 130. A third mounting assembly 180 is located between the first mounting assembly 130 and the first mounting plate 150 along the second horizontal direction D2. The third mounting assembly 180 is connected to the floor plate 120 and encloses the floor plate 120 to form a second receiving space 184 suitable for mounting an uninterruptible power supply.

[0088] When using the electrical compartment 110, the inverter (also known as a "power conversion system," abbreviated as PCS) and the high-voltage box are placed above and supported by the first support member 131. The uninterruptible power supply (UPS) is placed in the third housing space 111 and constrained by the third mounting component 180. Various power distribution components in the power distribution assembly and the first communication component are mounted on the first mounting plate 150 and the second mounting plate 170. The power distribution assembly may include high-current terminals, current transformers, circuit breakers, copper busbars, insulators, air switches, meters, relays, surge arresters, and other power distribution devices. The first communication component may include network cable adapters, communication terminals, and other communication devices for establishing communication connections.

[0089] According to an embodiment of the present invention, the electrical compartment 110, by arranging the first mounting assembly 130 and the second mounting assembly 140 along the second horizontal direction D2, with the first mounting assembly 130 housing the high-voltage box and inverter, and the second mounting assembly 140 accommodating the power distribution assembly and the first communication assembly, which are smaller in size than the high-voltage box and inverter, facilitates full utilization and improves space efficiency. Since the first mounting assembly 130 can arrange the high-voltage box and inverter along the vertical direction D3, its horizontal space occupation is reduced, leaving more usable space for the second mounting assembly 140, and simultaneously improving the vertical space utilization rate D3. Furthermore, this helps to increase the usable space of the second mounting assembly 140 in the vertical direction D3, thereby increasing the space available for arranging the power distribution assembly and the first communication assembly, which in turn helps to increase electrical safety clearances and improve electrical safety. In addition, by arranging the third mounting assembly 180 between the first mounting assembly 130 and the first mounting plate 150 to install an uninterruptible power supply, the structural compactness of the electrical compartment 110 is improved. Furthermore, compared to the individual power distribution devices in the power distribution assembly and the individual communication devices in the first communication assembly, the uninterruptible power supply (UPS) is larger in size and requires priority in allocating its distribution space. While the third mounting assembly 180 occupies a portion of the space enclosed by the first mounting assembly 130 and the second mounting assembly 140, the remaining space can be utilized to house the power distribution assembly and the first communication assembly. By adopting the above solution, the space utilization rate of the electrical compartment 110 can be improved, thereby facilitating the miniaturization of the electrical compartment 110.

[0090] See Figures 2 to 4 ,as well as Figures 6 to 9In some embodiments, the bottom plate 120 includes a main plate portion 123, a first recessed portion 124, and a second recessed portion 125. The main plate portion 123 is connected to a first mounting assembly 130, a second mounting assembly 140, and a third mounting assembly 180. The main plate portion 123 is located between the first recessed portion 124 and the second recessed portion 125 along a first horizontal direction D1. The first recessed portion 124 is located at the front end 121. The first recessed portion 124 is provided with a communication mounting portion 124a and a ventilation portion 124b. The communication mounting portion 124a and the ventilation portion 124b are arranged along a second horizontal direction D2. The communication mounting portion 124a is adjacent to the first mounting plate 150. The second recessed portion 125 is located at the rear end 122. The second recessed portion 125 is adapted to collect liquid. The second recessed portion 125 has a drain hole 125a. Functional zoning is achieved by dividing the floor plate 120 into a first recessed section 124, a main board section 123, and a second recessed section 125, distributed sequentially from front to back. The first recessed section 124 can accommodate a second communication component and ventilation equipment, which helps increase the volume of the electrical compartment 110 and improves the utilization of space in the front of the electrical compartment 110 along the vertical direction D3. Simultaneously, it prevents the installed second communication component and ventilation equipment from interfering with the disassembly and installation of the inverter and uninterruptible power supply along the first horizontal direction D1. The main board section 123 can accommodate the first mounting component 130, the second mounting component 140, and the third mounting component 180, serving as the main body supporting these structures. The second recessed area is used to collect liquids such as rainwater intruding from the rear ventilation openings and drains the collected liquid through the drain hole 125a to prevent liquid accumulation. Furthermore, the second recessed portion 125 can increase the distance between the power distribution components and electrical equipment located on the main board portion 123 and the rear ventilation opening, thereby preventing rainwater from reaching the electrical equipment.

[0091] Optionally, the bottom plate 120 is a one-piece metal plate.

[0092] See Figure 2 In some further embodiments, the electrical compartment 110 also includes a communication cover 191. The communication cover 191 is connected to the communication mounting portion 124a. The communication cover 191 and the communication mounting portion 124a are at least partially spaced apart. The space between the communication cover 191 and the communication mounting portion 124a is adapted to accommodate a second communication component. A clearance notch is provided at one end of the communication cover 191 near the first mounting plate 150. The upper surface of the communication cover 191 does not protrude from the upper surface of the main board portion 123. By providing the communication cover 191, the second communication component is protected by being covered after it is installed in the communication mounting portion 124a. The clearance notch at the end of the communication cover 191 near the first mounting plate 150 allows the communication harness of the second communication component to pass through and be routed nearby.

[0093] Optionally, the second communication component includes a communication terminal.

[0094] See Figures 2 to 4 ,as well as Figures 6 to 9 In some further embodiments, the motherboard portion 123 has an external cable pass-through hole 123a suitable for cable routing. By providing the external cable pass-through hole 123a, it is convenient for external power lines to pass through and be introduced into the electrical compartment 110.

[0095] Optionally, an external cable pass-through hole 123a is provided at one end of the motherboard portion 123 near the second recessed portion 125. There are multiple external cable pass-through holes 123a. The size of each external cable pass-through hole 123a can be different. In the illustrated example, the multiple external cable pass-through holes 123a include one large and two small circular holes.

[0096] In some further embodiments, the end of the main board portion 123 facing the front end 121 is higher than the end of the main board portion 123 facing away from the front end 121, so as to guide liquid flow to the second sinking portion 125. In the event of rainwater intrusion into the area where the main board portion 123 is located, the liquid can be guided by the main board portion 123 to the second sinking portion 125, thereby preventing water accumulation in the main board portion 123 and improving electrical safety.

[0097] Continue reading Figures 2 to 4 ,as well as Figures 6 to 9 In some embodiments, the floor plate 120 includes a main plate portion 123, a first recessed portion 124, and a second recessed portion 125. The main plate portion 123 is located between the first recessed portion 124 and the second recessed portion 125 along a first horizontal direction D1. The first mounting assembly 130 also includes two sets of support columns 132. The two sets of support columns 132 are arranged at intervals along a second horizontal direction D2. One set of support columns 132 is located at the end of the main plate portion 123 along the second horizontal direction D2. Both sets of support columns 132 are connected to the main plate portion 123. A first support member 131 is connected between the two sets of support columns 132. By connecting both sets of support columns 132 to the main plate portion 123, and connecting the first support member 131 to the support columns 132, the integrity and stability of the connection structure between the first mounting assembly 130 and the main plate portion 123 can be improved. Meanwhile, compared to arranging each of the two sets of support columns 132 separately in the main board section 123 and areas outside the main board section 123, it is more convenient to uniformly position the support columns 132, thereby reducing assembly difficulty, and it also helps to unify the length of the support columns 132, thereby reducing the design and processing difficulty of the support columns 132.

[0098] See also Figures 2 to 4 ,as well as Figures 6 to 9In further embodiments, the two sets of support columns 132 include a first front column 133, a second front column 134, and a rear column 135. The first front column 133 is located on the side of the second front column 134 facing away from the second mounting assembly 140 along a second horizontal direction D2. The first front column 133 and the second front column 134 are spaced apart and aligned along the second horizontal direction D2. The rear column 135 is located on the side of the second front column 134 facing the rear end 122 along a first horizontal direction D1. The rear column 135 is spaced apart and aligned with the second front column 134 along the first horizontal direction D1. The first support member 131 includes a first support member 131a and a second support member 131b arranged opposite each other. One end of the first support member 131a is connected to the first front column 133, and the other end extends along the first horizontal direction D1 above the rear end 122 to be adapted to connect to the column 101 on the rear side of the energy storage outdoor cabinet 100. The second support member 131b connects between the second front column 134 and the rear column 135. Since no other support column 132 is installed behind the first front support column 133, and instead the first support member 131a is connected to the first front support column 133 via the rear upright column 101 of the energy storage outdoor cabinet 100, the number of components can be reduced. Furthermore, compared to the second front support column 134 and the rear support column 135, since the first front support column 133 does not need to be connected to the second mounting plate 170, the size of the first front support column 133 along the second horizontal direction D2 can be reduced. This allows the first support member 131a to be arranged as close as possible to the end of the main board portion 123 along the second horizontal direction D2, further reducing the size of the first mounting assembly 130 along the second horizontal direction D2. The structure formed by the second front support column 134, the rear support column 135, and the second support member 131b connecting them can not only serve as a structure for installing and supporting the high-voltage box, but also be used to connect to the second mounting plate 170.

[0099] See Figures 2 to 4 ,as well as Figures 6 to 8In some further embodiments, the first support member 131 has a first support surface 131c for supporting the high-voltage box. The electrical compartment 110 also includes a cable storage box 138. The cable storage box 138 is connected between two sets of support columns 132. Along the vertical direction D3 of the electrical compartment 110, the top surface of the cable storage box 138 does not extend beyond the first support surface 131c. The cable storage box 138 is used to store cables. A first cable through-hole 138a is provided at the top of the cable storage box 138. A second cable through-hole 138b is provided at the end of the cable storage box 138 facing the first mounting plate 150. A first receiving space 137 is located between the cable storage box 138 and the compartment floor plate 120. The cable storage box 138 is provided to support and store the inverter cables. The first cable through-hole 138a is provided to allow cables from the inverter to pass through and connect to the high-voltage box. A second cable via 138b is provided to allow cables from the inverter to pass through and connect to the corresponding power distribution device located in the first mounting assembly 130.

[0100] See Figures 2 to 4 , Figure 6 ,as well as Figure 8 In some embodiments, the first mounting assembly 130 further includes a second support member 136. The second support member 136 is located below the first support member 131. A first receiving space 137 is defined between the second support member 136 and the first support member 131. The second support member 136 is used to support the inverter. Compared to placing the inverter directly on the upper surface of the floor plate 120, adding a second support member 136 to support the inverter improves the load-bearing capacity and stability of the inverter's support structure.

[0101] Optionally, the second support member 136 includes a pair of support members similar to the first support member 131a and the second support member 131b described above. The pair of support members are respectively connected to two sets of support columns 132.

[0102] In the example shown, the first support member 131a, the second support member 131b, and the support members are all plates with an L-shaped cross-section.

[0103] See Figures 2 to 6 ,as well as Figure 8In some embodiments, the first mounting plate 150 is arranged vertically. The first mounting plate 150 includes a first plate 151, a second plate 152, and a connecting plate 155 arranged sequentially along a first horizontal direction D1. The first plate 151 is adjacent to the rear end 122. The first plate 151 extends along the first horizontal direction D1. The second plate 152 extends in a direction inclined to the first horizontal direction D1 and away from the first mounting assembly 130. The second mounting assembly 140 also includes an insulator bracket 160. The insulator bracket 160 is connected to the first plate 151. The insulator bracket 160 has a plurality of insulator mounting surfaces 161 spaced apart along a second horizontal direction D2. The height of each insulator mounting surface 161 decreases sequentially along the direction close to the first plate 151. The first plate 151 is provided with an insulator mounting portion 151a. The insulator mounting portion 151a is spaced apart from the plurality of insulator mounting surfaces 161 along the second horizontal direction D2. Furthermore, the height of the insulator mounting portion 151a is lower than that of the multiple insulator mounting surfaces 161. The connecting plate 155 is adapted to connect to the column 101 on the front side of the outdoor energy storage cabinet 100. Through the multiple insulator mounting surfaces 161 of the insulator bracket 160 and the insulator mounting portion 151a located on the first plate 151, multiple insulators can be arranged and installed in a stepped manner. These insulators will be used to support and connect multiple copper busbars arranged in the vertical direction D3 to maintain electrical safety clearances that meet relevant requirements. This not only accommodates the installation of stepped copper busbars but also makes full use of the structure of the first plate 151, which helps to reduce the space occupied by the connection structure of all copper busbars and insulators in the second horizontal direction D2, further improving the space utilization rate of the electrical compartment 110 in the second horizontal direction D2. By providing a second plate 152 and arranging it at an angle relative to the first horizontal direction D1, it facilitates observation and operation from the front of the electrical compartment 110 when power distribution devices such as air switches, meters, relays, and surge arresters are installed on the second plate 152. Furthermore, it reduces the space occupied by the power distribution devices on the side of the first plate 151 facing the first mounting assembly 130. By providing a connecting plate 155, the first mounting plate 150 can be securely fixed when the connecting plate 155 is connected to the outdoor energy storage cabinet 100.

[0104] Optionally, the angle between the second plate 152 and the first horizontal direction D1 is 30° to 60°. Preferably, the angle between the second plate 152 and the first horizontal direction D1 is 45°.

[0105] Continue reading Figures 2 to 6 ,as well as Figure 8In some further embodiments, the first mounting plate 150 also includes a third plate 153. The third plate 153 extends along a first horizontal direction D1. The third plate 153 is connected between the end of the second plate 152 opposite to the first plate 151 and the connecting plate 155. The third plate 153 may be provided with a wire groove along the vertical direction D3. In addition, another wire groove along the vertical direction D3 may also be provided at the end of the first plate 151 near the second plate 152. The wire groove is used for routing and restraining cables to prevent cable arrangement from becoming messy.

[0106] See also Figures 2 to 6 ,as well as Figure 8 In some further embodiments, the first mounting plate 150 further includes a fourth plate 154. The fourth plate 154 extends along a direction intersecting a first horizontal direction D1. The fourth plate 154 and the second plate 152 are located on the same side of the third plate 153 along a second horizontal direction D2. The fourth plate 154 connects between the third plate 153 and the connecting plate 155. The fourth plate 154, the third plate 153, and the second plate 152 enclose a first receiving groove. The first receiving groove is used to accommodate a wire trough connected to the third plate 153 to make full use of space. The connecting plate 155 intersects with the fourth plate 154 to enclose a second receiving groove. The second receiving groove is used to accommodate a column 101 on the front side of the energy storage outdoor cabinet 100. When applied to the outdoor energy storage cabinet 100, the second plate 152, the third plate 153, and the fourth plate 154 of the first mounting plate 150 are located between the front column 101 and the rear column 101, which can make full use of the space between the front column 101 and the rear column 101.

[0107] Optionally, the first plate 151 and the fourth plate 154 are coplanar. The fourth plate 154 is used to mount the surface of the column 101 toward the other column 101 along the second horizontal direction D2.

[0108] Optionally, to ensure a safe electrical clearance, the first plate 151 also has an operating hole 151b. The operating hole 151b is an elongated hole. The length direction of the elongated hole is consistent with the first horizontal direction D1. The operating hole 151b is located on the side of the insulator mounting part 151a near the rear end 122.

[0109] Optionally, the first mounting plate 150 mentioned above is an integral plate made of metal plates through processes such as cutting and bending.

[0110] See Figure 3 , Figure 6 ,as well as Figure 8In some embodiments, the second mounting plate 170 includes a first mounting plate 171, a second mounting plate 172, and a third mounting plate 173 arranged sequentially along a first horizontal direction D1. The first mounting plate 171 is located on the side of the second mounting plate 172 facing away from the rear end 122. The first mounting plate 171 is arranged vertically. The first mounting plate 171 is connected to the first mounting plate 150 along a second horizontal direction D2. The second mounting plate 172 is arranged intersecting with the first mounting plate 171. The upper surface of the second mounting plate 172 is adapted to connect a current transformer. The second mounting plate 172 has a current transformer through hole 172a. The third mounting plate 173 is arranged intersecting with the second mounting plate 172. The end of the third mounting plate 173 facing away from the second mounting plate 172 is lower than the end of the third mounting plate 173 facing the second mounting plate 172. The third mounting plate 173 has a network cable adapter mounting part 173a.

[0111] When applied to the outdoor energy storage cabinet 100, the space on the side of the first mounting plate 171 away from the rear end 122 (i.e., the third mounting space mentioned above) is used to install a circuit breaker, the upper part of the second mounting plate 172 is used to install a current transformer, the current transformer through hole 172a of the second mounting plate 172 is used to pass through the cable connected to the current transformer, and the third mounting plate 173 is used to install high current terminals, network cable adapters, communication terminals and other devices.

[0112] With the above configuration, the space on the side of the first mounting plate 171 facing the front end 121, the upper space of the second mounting plate 172, and the space on one side of the third mounting plate 173 can be utilized.

[0113] Furthermore, the third mounting plate 173 is inclined in the vertical direction D3. The third mounting plate 173 extends downwards in the direction away from the front end 121. The space above the third mounting plate 173 is used to install high-current terminals, network cable adapters, communication terminals, and other devices to facilitate wiring, maintenance, and other operations from the rear of the electrical compartment 110.

[0114] Optionally, the angle between the third mounting plate 173 and the vertical direction D3 is 30° to 60°. Preferably, the angle between the third mounting plate 173 and the vertical direction D3 is 45°.

[0115] See Figures 2 to 4 ,as well as Figure 6In some embodiments, both the first mounting plate 171 and the second mounting plate 172 are spaced apart from the floor plate 120 along the vertical direction D3 of the electrical compartment 110. The space between the second mounting plate 172 and the floor plate 120 is suitable for accommodating an uninterruptible power supply (UPS). This arrangement allows for full utilization of the space below the first mounting plate 171 and the second mounting plate 172 when the space on the side of the second mounting plate 170 facing the front end 121 is insufficient to accommodate the UPS, thereby further improving the space utilization rate of the electrical compartment 110 in both the first horizontal direction D1 and the vertical direction D3.

[0116] Furthermore, the first mounting plate 171 is welded to the first plate 151 of the first mounting plate 150.

[0117] Furthermore, a diagonal brace 178 is connected between the second mounting plate 170 and the first mounting plate 150. The diagonal brace 178 is specifically connected between at least one of the second mounting plate 172 and the third mounting plate 173 and the first plate 151.

[0118] Optionally, the second mounting plate 170 is an integral plate made of metal sheet through processes such as cutting and bending.

[0119] Optionally, the second mounting plate 172 is arranged horizontally.

[0120] Optionally, the third mounting plate 173 is detachably connected to the rear support column 135. The second mounting plate 172 is detachably connected to the second support member 131b via a connecting bracket 177 or directly.

[0121] See Figures 2 to 4 ,as well as Figures 6 to 8 In some embodiments, the top of the third mounting assembly 180 is lower than the top of the first mounting assembly 130 and the top of the second mounting assembly 140, so as to form a third receiving space 111 enclosing the top of the third mounting assembly 180, the first mounting assembly 130, and the second mounting assembly 140. The third receiving space 111 is adapted to accommodate a portion of the power distribution assembly. This facilitates full utilization of the space above the third mounting assembly 180.

[0122] Furthermore, the third mounting assembly 180 is spaced apart from the first mounting plate 171 and the second mounting plate 172 in the vertical direction D3. In an application scenario where the second mounting assembly 140 is detachable as a whole, the power distribution assembly and the first communication assembly can be pre-installed on the second mounting assembly 140. Then, the second mounting assembly 140, equipped with the power distribution assembly and the first communication assembly, can be assembled onto the bottom plate 120, and then the third mounting assembly 180 can be installed onto the bottom plate 120. In short, this improves assembly efficiency.

[0123] Furthermore, along the second horizontal direction D2, the first mounting plate 150 and the third mounting assembly 180 are spaced apart to form a fourth receiving space 112. The fourth receiving space 112 is suitable for accommodating a portion of the power distribution components. That is, the third mounting assembly 180 is arranged close to the first mounting assembly 130 along the second horizontal direction D2, thereby leaving the fourth receiving space 112 between the third mounting assembly 180 and the first mounting plate 150. The fourth receiving space 112 can be used to accommodate power distribution devices such as switching power supplies.

[0124] See Figure 2 , Figure 7 ,as well as Figure 8 In some further embodiments, the third mounting assembly 180 includes a first limiting member 181, a second limiting member 182, and fastening bolts 183. The first limiting member 181 extends along the vertical direction D3 of the electrical compartment 110. The bottom end of the first limiting member 181 is connected to the bottom plate 120. There is a pair of first limiting members 181. The pair of first limiting members 181 are spaced apart along a second horizontal direction D2. The second limiting member 182 extends along the second horizontal direction D2. Both ends of the second limiting member 182 are screwed to the top ends of the pair of first limiting members 181 by fastening bolts 183. Before assembling the uninterruptible power supply (UPS), loosen the fastening bolt 183, raise the second limiting member 182 to a position that avoids the UPS, then place the UPS between the pair of first limiting members 181 and below the second limiting member 182, and then tighten the fastening bolt 183 until the second limiting member 182 presses against the UPS, thereby locking the UPS in place. The pair of first limiting members 181 are used to limit the UPS in the second horizontal direction D2. It is understood that when the UPS is not installed, if the fastening bolt 183 is tightened, the distance between the second limiting member 182 and the floor plate 120 is less than the height of the adapted UPS.

[0125] Optionally, the lower end of the first limiting member 181 is detachably connected to the bottom plate 120 by fasteners such as bolts.

When the third mounting assembly 180 is arranged close to the first mounting assembly 130, the fastening portions of both first limiting members 181 face downwards towards the first mounting plate 150 for easy assembly and disassembly.

[0127] See Figure 2 and Figure 3In some embodiments, a first electrical box connection portion is provided near the front end 121 of the first mounting plate 150.

By providing the electrical box panel 192, power distribution devices, cables, etc., can be concealed and hidden, thereby protecting the power distribution devices and cables while improving aesthetics. Because the electrical box panel 192 is removable, it facilitates inspection and maintenance of the power distribution components when necessary. The operating opening 192a on the electrical box panel 192 facilitates operation of air switches, circuit breakers, and observation of meter readings. The presence of an inlet / outlet on the electrical box panel 192 facilitates avoidance of uninterruptible power supplies.

[0128] Optionally, the first electrical box connection portion is located on the second front support 134. The second electrical box connection portion is located on the connecting plate 155 of the first mounting plate 150.

[0129] Optionally, there can be multiple operating openings 192a. The shape, size, and position of each operating opening 192a can be adapted to the actual application and are not limited here.

[0130] In some embodiments, the electrical compartment 110 further includes a support 193. The support 193 is disposed above the first mounting assembly 130 and the first mounting plate 150. The support 193 is adapted to connect to the bottom of the battery compartment 104 to support cables connecting the high-voltage box and the battery compartment 104. By providing the support 193, the space in the upper part of the electrical compartment 110 is further utilized, and it is also beneficial to rationally plan the wiring path and improve the aesthetics.

[0131] Optionally, when the electrical compartment 110 is applied to the outdoor energy storage cabinet 100, the support 193 is detachably connected to the skin 106 or base plate at the bottom of the battery compartment 104 by fasteners such as bolts. Space is reserved above the support 193 for cable routing.
