[0002] In the energy storage power station of the existing technology, it is necessary to install the energy storage converter cabinet, high-voltage switch cabinet, transformer cabinet and control cabinet separately on site. With the gradual increase of the capacity of new energy generation such as wind power generation and photovoltaic power generation and their continuous grid connection, the requirements for energy storage power stations are getting higher and higher. The original energy storage power station is inconvenient to install and cannot adapt to the harsh environment. Therefore, the integrated converter and booster came into being.

Among them, one end of the vacuum load switch is used to connect to the power grid, and the other end is connected to the high-voltage end of the transformer, and the low-voltage end of the transformer is connected to the energy storage converter.

[0006] However, in the process of using the above-mentioned energy storage and boost integrated equipment, since the energy storage inverter and transformer are two major heat-generating components, and the transformer chamber and the inverter chamber are separated only by a partition, the energy storage inverter and the transformer will heat each other through the partition, resulting in poor heat dissipation effect of the energy storage and boost integrated equipment, affecting the overall performance of the energy storage and boost integrated equipment.

[0028] In order to solve the problems in the background technology, the core inventive concept of the utility model is: by arranging the converter cabinet outside the box body, and forming a heat dissipation space connected to the outside world between the side wall of the converter cabinet and the side wall of the box body, on the one hand, the cold air from the outside can enter the heat dissipation space and cool the converter cabinet and the transformer room, thereby improving the heat dissipation effect; on the other hand, the air in the heat dissipation space can separate the converter cabinet and the transformer room, thereby preventing the converter cabinet and the transformer room from heating each other, thereby improving the heat dissipation effect of the converter and booster, and improving the overall performance of the converter and booster.

[0029] The present invention is further described in detail below in conjunction with the embodiments.

[0030] The specific embodiment of the current conversion and voltage boosting integrated machine provided by the utility model is as follows:

[0031] like Figure 1-2 As shown, the converter and booster comprises a box body 1, wherein the box body 1 has a transformer chamber 4 for arranging a working transformer 4-1 and a high-voltage chamber 5-1 for arranging a high-voltage switch, the transformer chamber 4 is arranged at one end of the box body 1, and the box body 1 is also provided with a mounting base 1-1-1 which is integrally connected to the box body 1 or separately fixed on the box body 1, and a converter cabinet 2 is mounted on the mounting base 1-1-1, and a set distance is provided between the side wall of the converter cabinet 2 and the side wall of the box body 1 to form a heat dissipation space 8 connected to the outside.

[0032] Specifically, in order to simplify the structure, the box body 1 includes a bottom plate 1-1 and a side plate that enclose the transformer chamber 4 and the high-voltage chamber 5-1. A part of the bottom plate 1-1 extends out of the transformer chamber 4 and the high-voltage chamber 5-1 to form a mounting base 1-1-1, and the structure is simple. Of course, in other specific embodiments, the mounting base 1-1-1 can also be fixedly connected to the side plate of the box body 1. Specifically, the mounting base 1-1-1 includes a mounting plate and a connecting plate for fixing the mounting plate and the side plate of the box body 1. In the vertical direction, the thickness of the mounting plate is less than the thickness of the connecting plate. The converter cabinet 2 is arranged on the mounting plate. At this time, the bottom plate 1-1 is located in the box body 1. In different specific embodiments, the mounting base 1-1-1 can be integrally formed with the base 1-1 of the box body 1; the mounting base 1-1-1 can also be separately arranged, so that the box body 1 and the mounting base 1-1-1 are a split structure, and the mounting base 1-1-1 is fixedly connected to the box body 1 by welding or flange connection. In this embodiment, the specific structure and connection method of the mounting base 1-1-1 and the box body 1 are not limited, as long as it can be ensured that the converter cabinet 2 can move synchronously with the box body 1 after being fixed on the mounting base 1-1-1, that is, the converter cabinet 2 and the box body 1 are fixed as one.

[0033] Specifically, as a specific implementation method, Figure 1 As shown, the top of the heat dissipation space 8 is connected to the outside, and along the Figure 1 In the direction perpendicular to the paper surface, both ends of the heat dissipation space 8 are connected to the outside world; of course, in other specific embodiments, refer to Figure 1 As shown, a cover plate may be provided between the converter cabinet 2 and the box body 1, so that the top of the heat dissipation space 8 is not connected to the outside. In this embodiment, the specific structure of the heat dissipation space 8 is not limited, as long as the heat dissipation space 8 can separate the transformer chamber 4 and the converter cabinet 2.

[0034] Specifically, Figure 1-2 As shown, as a specific implementation, a low-voltage chamber 9 is also provided in the box body 1, and a controller 7 for controlling the entire converter and booster is provided in the low-voltage chamber 9; however, in other specific implementations, the low-voltage chamber 9 may not be provided in the box body 1, and the controller 7 is provided in the high-voltage chamber 5-1 or the transformer chamber 4.

[0035] Among them, as a use mode of the integrated converter and booster, an energy storage converter is installed in the converter cabinet 2, a high-voltage switch is installed in the high-voltage chamber 5-1, and a working transformer 4-1 is installed in the transformer chamber 4; the energy storage converter is electrically connected to the low-voltage end of the working transformer 4-1, and the high-voltage end of the working transformer 4-1 is electrically connected to one end of the high-voltage switch, and the other end of the high-voltage switch is used to connect to the power grid when in use, and the energy storage converter is also electrically connected to the energy storage battery system on the user side. When the power grid is sufficient, the power grid supplies power to the energy storage battery system; when the power grid is insufficient, the energy storage battery system supplies power to the power grid. However, the integrated converter and booster in this embodiment can also be applied to other scenarios according to actual needs, and the application scenarios of the integrated converter and booster are not limited in this embodiment.

[0036] The transformer chamber 4 and the high-voltage chamber 5-1 are integrated by the box 1, and the structure is simple. The box 1 can be used to protect the components in the transformer chamber 4 and the high-voltage chamber 5-1, so that the converter and booster can be used in harsh environments. Specifically, the converter cabinet 2 and the box 1 both meet the IP65 protection level; the transformer chamber 4 is arranged at one end of the box 1, and a mounting base 1-1-1 is arranged on the bottom plate 1-1 of the box 1 close to the end of the transformer chamber 4, and the converter cabinet 2 can be installed on the mounting base 1-1-1 on the bottom plate 1-1 of the box 1, so that the converter cabinet 2 is also integrated into the box. 1, so that the assembly of the converter and booster can be completed in the factory, which is convenient for installing the converter and booster on site; at the same time, a set gap is left between the side wall of the converter cabinet 2 and the side wall of the box body 1 to form a heat dissipation space 8. On the one hand, external cold air can enter the heat dissipation space 8 and cool the converter cabinet 2 and the transformer chamber 4, thereby improving the heat dissipation effect. On the other hand, the air in the heat dissipation space 8 can separate the converter cabinet 2 and the transformer chamber 4, thereby preventing the converter cabinet 2 and the transformer chamber 4 from heating each other, thereby improving the heat dissipation effect of the converter and booster, and improving the overall performance of the converter and booster.

[0037] like Figure 1-3 As shown, in order to conveniently form a converter chamber and install the energy storage converter in the converter chamber, as a specific implementation method, the converter cabinet 2 itself has a converter chamber, and the energy storage converter is installed in the converter chamber. The structure is simple, and the ready-made converter cabinet 2 can be directly installed on the mounting base 1-1-1, which is convenient for installation. Specifically, the mounting base 1-1-1 is a mounting plate, and threaded holes are provided on the mounting plate. The converter cabinet 2 is threadedly connected to the mounting plate through the threaded holes on the mounting plate. Of course, in other specific implementation methods, the converter cabinet 2 can also be welded to the mounting plate. In different specific implementation methods, the mounting plate can be a rectangular plate; or, the mounting plate includes a fixed plate and a connecting plate, the converter cabinet 2 is installed on the fixed plate, and the two ends of the connecting plate are fixedly connected to the fixed plate and the box body 1 respectively, and the connecting plate is along Figure 1The length of the vertical direction in the paper is less than the length of the fixed plate. Figure 1 The length in the direction perpendicular to the paper surface, the number of connecting plates can be one, two or more.

[0038] In other specific embodiments, a converter room can be formed between the converter cabinet 2 and the mounting base 1-1-1, that is, the mounting base 1-1-1 on the bottom plate 1-1 of the box body 1 serves as the bottom plate 1-1 of the converter cabinet 2, thereby saving raw materials and reducing costs.

[0039] like Figure 3 As shown, in order to improve the heat dissipation capacity of the converter cabinet 2, as a specific implementation, the converter cabinet 2 is installed with an air conditioner 2-2 for blowing cold air into the converter room, thereby improving the heat dissipation capacity of the converter cabinet 2. Specifically, as Figure 3 As shown, the upper part of the converter cabinet 2 has an air inlet elbow 2-1, the lower side wall of the converter cabinet 2 has an air outlet 2-3, and the converter cabinet 2 has a corresponding heat dissipation fan. The air inlet elbow 2-1, the heat dissipation fan and the air outlet 2-3 constitute a first heat dissipation duct; the converter cabinet 2 is provided with air conditioners 2-2 on both opposite sides, and the air conditioners 2-2 blow cold air into the converter room. Specifically, in different specific embodiments, the cold air blown by the air conditioners 2-2 can be directly blown into the first heat dissipation duct; or, the cold air blown by each air conditioner 2-2 enters the independent second heat dissipation duct and the third heat dissipation duct, and the converter cabinet 2 is also provided with air outlets corresponding to the second heat dissipation duct and the third heat dissipation duct. Of course, in other specific embodiments, the air conditioner 2-2 may not be provided, and the converter cabinet 2 may be cooled only by the heat dissipation fan.

[0040] like Figure 1-2 As shown, in order to conveniently electrically connect the converter and the working transformer 4-1 and simplify the structure, as a specific implementation, a connecting pipe 3 is provided in the heat dissipation space 8, and its two ends are respectively connected to the converter chamber and the transformer chamber 4, and a conductive member for electrically connecting the converter and the working transformer 4-1 is provided in the connecting pipe 3. The structure is simple, and the converter and the working transformer 4-1 can be conveniently electrically connected. Specifically, the conductive member is a commonly used conductive member such as a cable or a conductive copper busbar.

[0041] However, in other specific embodiments, when the bottom plate 1-1 at one end of the box body 1 close to the transformer chamber 4 protrudes outward to form a mounting base 1-1-1, a first channel connecting the transformer chamber 4 and the converter chamber when in use is processed on the bottom plate 1-1 of the box body 1, and a conductive member is installed in the first channel to electrically connect the converter and the working transformer 4-1.

[0042] like Figure 1-3As shown, in order to simplify the structure and improve the heat dissipation effect of the high-voltage switch, as a specific implementation, the box body 1 is provided with an air inlet structure 1-4 and an air outlet structure, and the box body 1 is also provided with a heat dissipation fan for sending air from the air outlet structure, and the high-voltage chamber 5-1 is connected with the transformer chamber 4. Specifically, the inner cavity of the high-voltage switch cabinet 5 constitutes the high-voltage chamber 5-1. Compared with the closed high-voltage chamber 5-1 formed by the closed high-voltage switch cabinet 5, the high-voltage chamber 5-1 is connected with the transformer chamber 4 (that is, the high-voltage switch cabinet 5 is an open frame structure). On the one hand, the weight of the converter and booster can be reduced by reducing the weight of the high-voltage switch cabinet 5; on the other hand, it is beneficial to the heat dissipation of the high-voltage switch, and the heat dissipation effect of the high-voltage switch can be improved. There is no need to design an additional heat dissipation fan in the high-voltage chamber 5-1, which can reduce the use of the fan and simplify the structure.

[0043] However, in other specific embodiments, a liquid cooling channel may be provided on the box body 1 to cool the transformer chamber 4 and the high-voltage chamber 5-1 by liquid cooling. Specifically, when in use, the liquid cooling channel is connected to the heat exchanger through a pipeline to form a loop, and the heat exchanger exchanges heat with the outside air to cool the coolant in the entire loop.

[0044] Of course, in other specific embodiments, the high-voltage switch cabinet 5 can also be a closed high-voltage switch cabinet 5. In this case, the high-voltage chamber 5-1 and the transformer chamber 4 are two independent chambers, and the box body 1 is respectively provided with air inlet structures 1-4, air outlet structures and heat dissipation fans corresponding to the high-voltage chamber 5-1 and the transformer chamber 4.

[0045] like Figure 1-3 As shown, in order to facilitate the maintenance of the working transformer 4-1, the high-voltage switch and the controller 7, as a specific implementation, the box body 1 is provided with a transformer chamber door 1-2 corresponding to the transformer chamber 4, a high-voltage chamber door corresponding to the high-voltage chamber 5-1 and a low-voltage chamber door 1-3 corresponding to the low-voltage chamber 9. After opening different doors, different devices can be directly maintained, and the staff does not need to enter the box body 1, which is convenient for maintenance. At the same time, after opening the low-voltage chamber door 1-3, the controller 7 can also be conveniently operated.

[0046] Reference Figure 1-3As shown, in order to simplify the structure and ensure the safety of the staff, as a specific implementation method, the upper end of the high-voltage chamber 5-1 is connected to the upper end of the low-voltage chamber 9, so that there is no need to set a fan and corresponding air inlet and outlet separately in the low-voltage chamber 9, the structure is simple, and the height of the connection between the high-voltage chamber 5-1 and the low-voltage chamber 9 is greater than the height of the staff, so as to avoid the staff from contacting the high voltage electricity when operating the controller 7. However, in other specific implementation methods, a mesh can also be set on the partition between the high-voltage chamber 5-1 and the low-voltage chamber 9, and the height of the mesh is lower than the height of the staff. Under the premise that the high-voltage chamber 5-1 is connected to the low-voltage chamber 9, the partition can ensure that the staff will not contact the high-voltage switch when operating the controller 7, so as to avoid the staff from contacting the high voltage electricity when operating the controller 7. Of course, in other specific implementation methods, the upper end of the low-voltage chamber 9 can also be connected to the upper end of the transformer chamber 4, so that there is no need to set a fan and corresponding air inlet and outlet separately in the low-voltage chamber 9.

[0047] like Figure 1-6 As shown, in order to avoid dust accumulation or moisture in the box body 1, as a specific embodiment, the air inlet structure 1-4 is an air inlet louver and a mesh plate 1-4-1 located downstream of the air inlet louver, and the mesh plate 1-4-1 is filled with a filter element for filtering dust. Specifically, the air inlet louver and the mesh plate 1-4-1 are fixedly connected to the box door, and the filter element is filter cotton, which can filter dust and absorb water vapor, thereby avoiding dust accumulation or moisture in the box body 1, so that the variable current booster can adapt to harsh environments with large dust such as the Gobi Desert. The air outlet structure is an air outlet elbow 1-5, and the air outlet of the air outlet elbow 1-5 points downward to prevent rainwater from falling into the air outlet elbow 1-5. However, in other specific embodiments, the filter element can also be a filter bag filled with activated carbon; the air inlet louver and the mesh plate 1-4-1 can also be set on other parts of the box body 1 except the box door.

[0048] Reference Figure 3 As shown, in other specific embodiments, the air inlet structure 1-4 can also be an air inlet elbow 2-1 arranged on the upper part of the box body 1, and the air inlet of the air inlet elbow 2-1 points downward to prevent rainwater from falling into the air inlet elbow 2-1; the air outlet structure is an air outlet louver, and a mesh plate 1-4-1 is provided downstream of the air outlet louver, and the mesh plate 1-4-1 is filled with a filter element for filtering dust.

[0049] Reference Figure 2As shown, in order to simplify the structure and reduce the cost, as a specific implementation method, a power transformer 6 is installed in the low-voltage chamber 9, and the input end of the power transformer 6 is used to be electrically connected to the low-voltage end of the working transformer 4-1 in the transformer chamber 4, and the controller 7 is electrically connected to the output end of the power transformer 6 (that is, the output end of the power transformer 6 is connected to the controller 7 for controlling the entire converter and booster), so that when the power grid is sufficient, the power grid is used to power the controller 7, and when the power grid is insufficient, the energy storage battery system is used to power the controller 7, with a simple structure and low cost.

[0050] However, in other specific implementations, a UPS (Uninterruptible Power Supply) may be separately provided in the low-voltage chamber 9 to supply power to the controller 7 .

[0051] like Figure 1-3 As shown, in order to simplify the structure, as a specific implementation, the low-voltage chamber 9 is connected to the transformer chamber 4, so there is no need to set a separate air outlet structure and a heat dissipation fan at the corresponding position of the box body 1 and the low-voltage chamber 9, and only the air inlet structure 1-4 is set at the corresponding part of the box body 1 and the low-voltage chamber 9 to increase the air intake into the box body 1, and the structure is simple. However, in other specific implementations, the low-voltage chamber 9 can also be a separate chamber, and the air inlet structure 1-4, the air outlet structure and the heat dissipation fan are set at the corresponding position of the box body 1 and the low-voltage chamber 9.

[0052] Finally, it should be noted that the above are only preferred embodiments of the utility model and are not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments without creative work, or replace some of the technical features therein by equivalents.
