Of course, the combiner function of integrated energy storage combiner and booster units is mainly achieved by designing combiner cabinets on the outside of outdoor buildings.

[0008] Of the four components—the high-voltage compartment, the auxiliary transformer compartment, the intelligent control compartment, and the combiner compartment—two are located on the first side of the medium-voltage compartment, and the other two are located on the second side of the medium-voltage compartment. The first side and the second side are two opposite sides of the medium-voltage compartment along a first direction.

[0009] In some embodiments of this application, the high-voltage output line and the low-voltage output line are respectively disposed on two opposite sides of the medium-voltage transformer along the first direction, the high-voltage compartment is disposed outside the medium-voltage compartment on the side corresponding to the location of the high-voltage output line, and the combiner compartment is disposed outside the medium-voltage compartment on the side corresponding to the location of the low-voltage output line.

[0010] In some embodiments of this application, the auxiliary transformer compartment and the manifold compartment are located on the same side of the medium-pressure compartment; the intelligent control compartment and the high-pressure compartment are located on the same side of the medium-pressure compartment.

[0011] In some embodiments of this application, the auxiliary transformer compartment and the combiner compartment are arranged along a second direction; and / or, the intelligent control compartment and the high-voltage compartment are arranged along a second direction;

[0012] The second direction is a direction that is parallel to the horizontal plane and perpendicular to the first direction.

[0013] In some embodiments of this application, the intelligent control compartment and the manifold compartment are located on the same side of the medium-voltage compartment; the auxiliary transformer compartment and the high-voltage compartment are located on the same side of the medium-voltage compartment.

[0014] In some embodiments of this application, the intelligent control compartment and the manifold compartment are arranged along a second direction; and / or, the auxiliary transformer compartment and the high-voltage compartment are arranged along a second direction;

[0015] The second direction is a direction that is parallel to the horizontal plane and perpendicular to the first direction.

[0016] In some embodiments of this application, the high-voltage outgoing line and the low-voltage outgoing line are located on the same side of the medium-voltage transformer, and the high-voltage compartment and the combiner compartment are located outside the medium-voltage compartment on the outgoing side of the medium-voltage transformer.

[0017] In some embodiments of this application, the high-voltage compartment and the manifold compartment are arranged along a second direction; and / or, the intelligent control compartment and the auxiliary transformer compartment are arranged along a second direction;

[0018] The second direction is a direction that is parallel to the horizontal plane and perpendicular to the first direction.

[0019] In some embodiments of this application, the medium-voltage transformer is a dry-type transformer; and / or, the auxiliary transformer is a dry-type transformer.

[0020] In some embodiments of this application, the medium-pressure chamber is provided with a first ventilation opening and a second ventilation opening on two opposite sides along the second direction, and a cooling fan is provided at the first ventilation opening and / or the second ventilation opening.

[0021] In some embodiments of this application, a rain cover is provided on the outside of the outdoor room above the cooling fan.

[0022] To address the issue of low space utilization and large overall size in integrated energy storage and converter transformers, this application provides an integrated energy storage and converter transformer, including an outdoor housing. The outdoor housing contains a medium-voltage compartment, a high-voltage compartment, an auxiliary transformer compartment, an intelligent control compartment, and a converter compartment. The medium-voltage compartment houses a medium-voltage transformer. The high-voltage compartment houses high-voltage electrical components connected to the high-voltage output of the medium-voltage transformer. The converter compartment houses converter electrical components connected to the low-voltage output of the medium-voltage transformer. The auxiliary transformer compartment houses an auxiliary transformer. The intelligent control compartment houses low-voltage control components. Two of the four compartments—the high-voltage compartment, the auxiliary transformer compartment, the intelligent control compartment, and the converter compartment—are located on the first side of the medium-voltage compartment, and the other two are located on the second side of the medium-voltage compartment. The first and second sides are two opposite sides of the medium-voltage compartment along a first direction. Compared to the traditional solution where the combiner cabinet is located on the outside of the outdoor building, the energy storage combiner and booster unit provided in this application eliminates the combiner cabinet on the outside of the outdoor building. Instead, it sets up a combiner compartment inside the outdoor building and, through a reasonable layout, places two of the four compartments—the high-voltage compartment, the auxiliary transformer compartment, the intelligent control compartment, and the combiner compartment—on the first side of the medium-voltage compartment, and the other two on the second side. The first and second sides are two opposite sides of the medium-voltage compartment along the first direction. This not only avoids the problem of excessive redundant space on both sides of the combiner cabinet, which would otherwise be wasted, but also makes reasonable use of the internal space of the outdoor building, greatly improving space utilization and reducing the overall size of the unit.

[0024] Furthermore, this application also provides a photovoltaic power station, including an energy storage system, which is the energy storage system described in the above-mentioned scheme. Since the aforementioned energy storage system has the above-mentioned technical effects, the photovoltaic power station with this energy storage system should also have the corresponding technical effects, which will not be elaborated further here.

[0049] The core of this application is to provide an integrated energy storage combiner and boost converter, an energy storage system, and a photovoltaic power station to solve the problem of large overall size caused by low space utilization of the integrated energy storage combiner and boost converter.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] String electrochemical energy storage, as an emerging energy storage technology, has achieved significant development in the new energy field in recent years. For large factories or residential areas, available space is limited, and the demand for energy storage battery capacity is high, while the requirement for charging and discharging speed is not too high. When using commercial energy storage systems, projects with the same capacity require a larger footprint compared to centralized solutions. Furthermore, commercial energy storage cabinets are expensive, and the need for cables and other accessories is greater, resulting in poor economic efficiency. Therefore, reducing the size and cost of the core equipment in this system, the integrated busbar booster unit, is of great significance.

[0052] Currently, integrated energy storage combiner and booster units have an outdoor enclosure containing a medium-voltage compartment, a high-voltage compartment, an auxiliary transformer compartment, and an intelligent control compartment, with the combiner cabinet located on the outside of the outdoor enclosure. The medium-voltage compartment houses the medium-voltage transformer, the high-voltage compartment contains high-voltage electrical components connected to the high-voltage output of the medium-voltage transformer, the auxiliary transformer compartment contains the auxiliary transformer, the intelligent control compartment contains the low-voltage control components, and the combiner cabinet contains combiner electrical components connected to the low-voltage output of the medium-voltage transformer. However, the current design of the combiner cabinet on the outside of the outdoor enclosure results in redundant space on both sides, leading to low space utilization and a large overall unit size.

[0053] Based on this, the present application provides an integrated energy storage combiner and booster unit to solve the problem of large overall size caused by low space utilization in integrated energy storage combiner and booster units.

[0054] Specifically, refer to Figure 1 As shown, the energy storage and booster integrated unit provided in this application specifically includes an outdoor room 1. The outdoor room is equipped with a medium-voltage compartment 11, a high-voltage compartment 12, an auxiliary transformer compartment 13, an intelligent control compartment 14, and a combiner compartment 15. The medium-voltage compartment 11 is equipped with a medium-voltage transformer 110. The high-voltage compartment 12 is equipped with a high-voltage electrical component connected to the high-voltage output line 111 of the medium-voltage transformer 110. The combiner compartment 15 is equipped with a combiner electrical component connected to the low-voltage output line 112 of the medium-voltage transformer 110. The auxiliary transformer compartment 13 is equipped with an auxiliary transformer 130. The intelligent control compartment 14 is equipped with a low-voltage control component.

[0055] The main function of the high-voltage electrical components in the high-voltage chamber 12 is to serve as the primary protection device for connecting and disconnecting the medium-voltage side from the power grid.

[0056] The main function of the combiner electrical component is to combine the current in the energy storage battery pack (not shown in the figure), and it is also responsible for distributing power to the low-voltage control components in the intelligent control compartment 14 of the integrated machine. The energy storage battery pack can be, but is not limited to, a string energy storage battery pack. The main function of the auxiliary transformer 130 is to transform the AC power drawn from the combiner compartment 15 to the AC power required by the intelligent control cabinet.

[0057] For example, the auxiliary transformer 130 can specifically transform the 690V AC power drawn from the combiner compartment 15 to the 400V AC power required by the intelligent control cabinet.

[0058] The main function of the intelligent control compartment 14 is to provide auxiliary power and fire protection power for the energy storage combiner and booster unit, as well as control related low-voltage electrical components such as lighting, heat dissipation, and fire signals.

[0059] Compared to the traditional approach of placing the combiner cabinet on the outside of the outdoor room, the energy storage combiner and booster unit provided in this application eliminates the combiner cabinet on the outside of the outdoor room 1. Instead, it incorporates a combiner compartment 15 inside the outdoor room 1. Specifically, through a well-planned layout, two of the four compartments—high-voltage compartment 12, auxiliary transformer compartment 13, intelligent control compartment 14, and combiner compartment 15—are located on the first side of the medium-voltage compartment 11, while the other two are located on the second side. The first and second sides are two opposite sides of the medium-voltage compartment 11 along a first direction, specifically referring to the length of the outdoor room 1. This layout of the outdoor room 1 not only avoids the problem of excessive redundant space on both sides of the combiner cabinet, thus preventing space waste, but also makes reasonable use of the internal space of the outdoor room, greatly improving space utilization and reducing the overall size of the unit.

[0060] In some specific implementation plans, refer to Figures 2-5 , combined Figure 1 ,in, Figure 1 The diagram shows the medium-voltage transformer 110 using a configuration where high and low voltage lines exit on the same side, but it is not limited to this configuration. For example... Figures 2-5 The aforementioned medium-voltage transformer 110 can specifically employ different side outputs, meaning the high-voltage output 111 and the low-voltage output 112 are respectively located on two opposite sides of the medium-voltage transformer 110 along the first direction. Specifically, the high-voltage compartment 12 is located outside the medium-voltage compartment 11 on the side corresponding to the high-voltage output 111, and the bus compartment 15 is located outside the medium-voltage compartment 11 on the side corresponding to the low-voltage output 112. The advantage of this structural form is that the high and low voltages are located on different sides, which further enhances safety.

[0061] in, Figures 2-5 The diagram shows four layout structures of the energy storage combiner and step-up unit from a top-down perspective when the high-voltage output line 111 and the low-voltage output line 112 of the medium-voltage transformer are located on different sides.

[0062] Specifically, refer to Figure 2 and Figure 3 The layout shown is as follows: the auxiliary transformer compartment 13 and the combiner compartment 15 are located on the same side of the medium-voltage compartment 11, which makes the wiring of the relevant electrical components between the auxiliary transformer compartment 13 and the combiner compartment 15 more convenient. The intelligent control compartment 14 and the high-voltage compartment 12 are located on the same side of the medium-voltage compartment 11, which makes the wiring between the relevant electrical components in the intelligent control compartment 14 and the relevant electrical components in the high-voltage compartment 12 more convenient.

[0063] Furthermore, referring to Figure 2 and Figure 3To minimize spatial redundancy, the auxiliary transformer compartment 13 and the junction compartment 15 can be designed to be arranged along the second direction, and their positions can be interchanged. Similarly, the intelligent control compartment 14 and the high-voltage compartment 12 can also be designed to be arranged along the second direction, and their positions can be interchanged. The second direction is parallel to the horizontal plane and perpendicular to the first direction. This structural design reduces the redundant space of the outdoor room 1 in the second direction.

[0064] Reference Figure 4 and Figure 5 The layout shown is such that the intelligent control compartment 14 and the combiner compartment 15 are located on the same side of the medium-voltage compartment 11, making wiring between the relevant electrical components in the intelligent control compartment 14 and the relevant electrical components in the combiner compartment 15 more convenient. Similarly, the auxiliary transformer compartment 14 and the high-voltage compartment 12 are located on the same side of the medium-voltage compartment 11, making wiring between the relevant electrical components in the auxiliary transformer compartment 14 and the high-voltage compartment 12 more convenient.

[0065] Furthermore, to minimize spatial redundancy, the intelligent control compartment 14 and the junction compartment 15 can be designed to be arranged along the second direction, and their positions can be interchanged. The auxiliary transformer compartment 13 and the high-voltage compartment 12 can also be designed to be arranged along the second direction. The second direction is parallel to the horizontal plane and perpendicular to the first direction. This structural design reduces the redundant space of the outdoor room 1 in the second direction.

[0066] In some other specific implementation schemes, combined with Figure 1 The high-voltage output line 111 and the low-voltage output line 112 are located on the same side of the medium-voltage transformer 110. For example, the high-voltage output line 111 and the low-voltage output line 112 can be distributed along the height of the medium-voltage transformer 110.

[0067] Reference Figure 6 and Figure 7 The layout shown is as follows: both the high-voltage compartment 12 and the combiner compartment 15 are located outside the medium-voltage compartment 11, corresponding to the outgoing line side of the medium-voltage transformer 110. This design allows the high and low voltage outgoing lines of the medium-voltage transformer 110 to be wired on the same side, making the operation more efficient.

[0068] In a further implementation scheme, to minimize spatial redundancy, the high-voltage compartment 12 and the junction compartment 15 can be designed to be arranged along the second direction, and their positions can be interchanged. Similarly, the intelligent control compartment 14 and the auxiliary transformer compartment 13 can also be designed to be arranged along the second direction, and their positions can be interchanged. The second direction is parallel to the horizontal plane and perpendicular to the first direction. By designing this structure, the redundant space of the outdoor room 1 in the second direction can be reduced.

[0069] It should be noted that the medium-voltage transformer 110 mentioned above can be, but is not limited to, a dry-type transformer; similarly, the auxiliary transformer 130 can be, but is not limited to, a dry-type transformer. For example, the medium-voltage transformer 110 and the auxiliary transformer 130 can also be designed as other types of transformers, such as oil-immersed transformers, depending on actual needs. In practical applications, the configuration can be selected according to specific requirements, and no specific limitations are made here.

[0070] In some specific implementation plans, refer to Figure 1 Specifically, the aforementioned medium-voltage compartment 11 can be designed with a first ventilation opening 113 and a second ventilation opening 114 respectively on two opposite sides along the second direction, and a cooling fan 115 is installed at the first ventilation opening 113 and / or the second ventilation opening 114. This design allows a cooling airflow to be formed inside the medium-voltage compartment 11, which helps to reduce the internal temperature of the medium-voltage compartment 11, thereby improving the operational safety and efficiency of the medium-voltage transformer 110.

[0071] In some other specific implementations, a rain cover 116 can also be installed on the outside of the outdoor room 1 above the cooling fan 115. By designing the rain cover 116, rainwater can be effectively prevented from damaging the cooling fan 115, which can help extend the service life of the cooling fan 115, and at the same time, it can also minimize the possibility of rainwater entering the medium-pressure chamber 11 through the cooling fan 115.

[0072] On the other hand, this application also provides an energy storage system, including an integrated energy storage combiner and booster unit as described in any of the above schemes. Since the aforementioned integrated energy storage combiner and booster unit has the above-mentioned technical effects, the energy storage system having the integrated energy storage combiner and booster unit should also have the corresponding technical effects, which will not be elaborated here.

[0073] Furthermore, this application also provides a photovoltaic power station, including an energy storage system, which is the energy storage system described in the above-mentioned scheme. Since the aforementioned energy storage system has the above-mentioned technical effects, the photovoltaic power station with this energy storage system should also have the corresponding technical effects, which will not be elaborated further here.

[0074] It should be noted that the power cabinet can be a converter power cabinet or other types of power cabinets, and no specific limitation is made here.

[0075] It should also be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
