TECHNICAL FIELD

[0001] The utility model relates to the technical field of power grid management equipment, especially to a low voltage management equipment and box structure thereof. BACKGROUND

[0002] Low voltage refers to the voltage value of the user side being lower than the lower limit value of the voltage stipulated by the state, and low voltage generally occurs with the increase of the load of the user side, which will directly affect the operation of enterprises and the daily life of residents, therefore, it is crucial to take effective technical means to govern the low voltage problem. The existing common low voltage management technical means include adjusting the output voltage of the transformer, adjusting the load of three phases, reducing the loss of reactive voltage, adjusting the load through the energy storage device, etc., wherein, using the energy storage device can not only maintain the voltage stability, but also store electric energy when the power grid load is low, which can guarantee the overall efficiency of the power grid and is an important means among the common methods for low voltage management.

[0003] The battery is a component of the energy storage device in low voltage management, and compared with the control module, it has the characteristics of large volume and large weight. The installation position of the energy storage device includes: the substation position, the appropriate position (generally the middle position or the end position) of the distribution line, and the line on the user side. Among them, for the characteristics of rural power grids, in order to improve the efficiency of implementing low voltage management and reduce the setting cost, the preferred method is to install the energy storage device on the tower of the distribution line in the low voltage management based on the energy storage device.

[0004] The energy storage device generally includes a battery and a control module, and the specific implementation scheme is provided in the technical solution of patent application No. CN202011450856.0, and the battery and the control module are generally built-in in the equipment box, which is supported on the installation support fixed on the power grid tower. Through retrieval, the specific installation mode is similar to that in the specification attached to the patent application No. CN201721158360. X. Figure 5 The installation scheme is shown.

[0005] In order to improve the convenience of the use of the energy storage device in the power grid, it is necessary to further optimize the related technical solutions. UTILITY MODEL CONTENT

[0006] In order to solve the problem of optimizing the convenience of the use of the energy storage device in the power grid, the utility model provides a low voltage management equipment and box structure thereof. The scheme can configure appropriate battery module capacity according to the actual needs of the use position of the energy storage device, and solves the adaptability problem of the equipment box.

[0007] To solve the above problems, the low-voltage treatment equipment and the box structure thereof provided by the utility model solve the problems through the following technical points: the low-voltage treatment equipment box structure comprises an equipment box and a support assembly for supporting the equipment box, the equipment box comprises a first box body for mounting a control module, and the equipment box further comprises a second box body for mounting a battery module; the first box body and the second box body are relatively independent box bodies, the first box body and the second box body can be stacked in a stacked structure in the vertical direction, and the stacked structure can be supported on the support assembly.

[0008] In the prior art, the low-voltage treatment equipment based on an energy storage device comprises the following functions: when it is detected that the load on the line is greater than a set value or the voltage is lower than a set value, the load on the power supply side of the line is reduced and the household voltage of the user is ensured by discharging energy to the power grid. Such a structure usually comprises a control module and a battery module, the control module is electrically connected with the battery module, the battery module serves as an energy storage component, and the control module serves as a control component for controlling the energy storage of the battery module and discharging energy to the power grid. At the same time, such equipment is usually integrated into a complete set of equipment, and a general structure comprises an equipment box, the battery module and the control module are built-in in the equipment box to provide protection for the related modules by the equipment box.

[0009] In the prior art, the battery module and the control module generally share one equipment box, that is, the equipment usually comprises one box structure, and the battery module and the control module are built-in in the box structure. At the same time, among the control module and the battery module, the control module generally has a comparable volume, while the battery module has a significant volume difference. For equipment installed on a power grid tower, such as overhead installation, in order to reasonably control the size of the equipment box and reduce the overall weight of the equipment, the internal space of the equipment box is generally configured to only meet the current battery module installation needs (the internal space is determined according to the volume of the battery module, and the setting mode of having a rich space for later expansion is generally not adopted considering the equipment weight and setting cost, etc.), so that different application occasions with different low-voltage treatment capacity needs can meet the low-voltage treatment needs of different positions of the power grid by setting different models of the equipment box, and different models of the equipment box have different battery module accommodation capacities. When the energy storage capacity of the battery module in the equipment box is insufficient to meet the user side power demand, since the original equipment box does not have the capacity to expand the battery module, the equipment box needs to be replaced or even the complete set of equipment needs to be replaced. Therefore, the existing low-voltage treatment equipment based on an energy storage device has the problems of inconvenient configuration of the battery module capacity and the need for multiple models of the equipment box to solve the adaptability needs of different positions of the power grid, and the box structure is provided based on the problem.

Since the first box and the second box can be stacked into a stacked structure in the vertical direction, when the capacity of the low-voltage treatment equipment is configured according to specific applications, the appropriate number of second boxes can be selected according to specific needs to complete the installation of the required battery module. When the low-voltage treatment equipment applied to the power grid needs to be expanded, only the second boxes for installing new battery modules need to be added according to the expansion capacity on the basis of the original stacked structure. Therefore, the box structure provided by the present scheme can flexibly configure the number of second boxes according to the actual needs of the battery module. For example, a uniform second box size is set according to specific applications, and the appropriate number of second boxes can be selected according to the needs of different use positions or expansion needs during use. In this way, not only are the adaptability of the equipment box under the initial capacity requirements of the newly invested low-voltage treatment equipment and the adaptability of the equipment box under the expansion requirements of the later period solved, but also the problem of conveniently installing the required first box and second box on the support assembly is solved. At the same time, it is beneficial to the convenience of preparing and configuring the second box.

[0015] In the layering structure, the box body at the bottom side is the first box body, and a plurality of second box bodies are layered above the first box body. The application is a convenient installation form. When expanding the capacity, the control module generally has a relatively wide capacity adaptation range.

DETAILED DESCRIPTION

[0037] The present utility model will be further described in detail below in combination with embodiments, but the present utility model is not limited to the following embodiments:

[0038] Embodiment 1

[0039] As shown in Figures 1 to 8 , the low-voltage treatment equipment box structure includes an equipment box and a support assembly 1 for supporting the equipment box, the equipment box includes a first box body 22 for mounting a control module 24, and the equipment box further includes a second box body 32 for mounting a battery module 31, the first box body 22 and the second box body 32 are relatively independent box bodies, the first box body 22 and the second box body 32 can be stacked in a stacked structure in the vertical direction, and the stacked structure can be supported on the support assembly 1.

[0040] In the prior art, the low-voltage treatment equipment based on energy storage equipment includes the following functions: when it is detected that the load on the line is greater than a set value or the voltage is lower than a set value, the load on the power supply side of the line is reduced and the voltage of the user is ensured by discharging energy to the power grid. Such a structure generally includes a control module 24 and a battery module 31. The control module 24 is electrically connected to the battery module 31. The battery module 31 serves as an energy storage component, and the control module 24 serves as a control component for controlling the energy storage and discharging of the battery module 31. At the same time, such equipment is usually integrated into a complete set of equipment, and in a general structure, it includes an equipment box. The battery module 31 and the control module 24 are built into the equipment box to provide protection for the related modules using the equipment box.

[0041] In the prior art, the battery module 31 and the control module 24 generally share one equipment box, i.e., the equipment usually includes a box structure, and the battery module 31 and the control module 24 are built into the box structure. At the same time, among the two, the control module 24 and the battery module 31, for different treatment capacity / equipment, the control module 24 generally has a comparable volume, while the battery module 31 has a significant volume difference. For equipment such as overhead installation on a power grid tower, it is generally appropriate to configure the internal space of the equipment box to only be able to adapt to the current battery module 31 installation needs (the internal space is determined according to the volume of the battery module 31, and considering the equipment weight and installation cost, etc., generally not using a setting method with ample space for future expansion), so that for different use occasions with different low-voltage treatment capacity needs, to meet the low-voltage treatment needs of each position of the power grid, it is necessary to set different models of equipment boxes, and different models of equipment boxes have different battery module 31 capacity. When the energy storage capacity of the battery module 31 in the equipment box is insufficient to meet the user side power demand, since the original equipment box does not have the ability to expand the battery module 31, at this time it is necessary to replace the equipment box or even the complete set of equipment. Therefore, the existing low-voltage treatment equipment based on energy storage equipment has the problems of inconvenient configuration of the battery module 31 capacity and the need for multiple types of equipment boxes to solve the adaptability needs of different positions of the power grid. Based on this problem, the above box structure is provided.

[0042] In the structural design of the above box structure, the first box body 22 and the second box body 32 are respectively arranged for the control module 24 and the battery module 31, that is, in the low-voltage treatment equipment using the box structure, the control module 24 is installed in the first box body 22 to form a control box assembly 2, and the battery module 31 is installed in the second box body 32 to form a battery box assembly 3. Since the first box body 22 and the second box body 32 can be stacked in a stacked structure in the vertical direction, when the capacity of the low-voltage treatment equipment is configured according to the specific application, the number of second box bodies 32 can be selected according to the specific needs to complete the installation of the required battery module 31. When the low-voltage treatment equipment applied to the power grid needs to be expanded, only the second box body 32 is added according to the expansion capacity to install the new battery module 31. Therefore, the box structure provided by the present scheme can flexibly configure the number of second box bodies 32 according to the actual needs of the battery module 31. For example, a uniform size of the second box body 32 is set according to the specific application, and the appropriate number of second box bodies 32 is selected according to the needs of different use positions or expansion needs during use. In this way, not only the adaptability of the equipment box under the initial capacity requirement of the newly invested low-voltage treatment equipment and the adaptability of the equipment box under the expansion requirement of the later period are solved, but also the problem of conveniently installing the required first box body 22 and second box body 32 on the support assembly 1 is solved, which is beneficial to the convenience of preparing and configuring the second box body 32.

[0043] In one specific application, according to the capacity of the conventional battery module 31 at present, the second box body 32 is preferably set to have the capacity to accommodate two battery modules 31.

[0044] Embodiment 2:

[0045] This embodiment is further refined on the basis of embodiment 1:

[0046] The second box body 32 is a box structure with a second box cover 33 arranged on the side, and the first box body 22 is a box structure with a first box cover 21 arranged on the top. In the application, the second box cover 33 and the first box cover 21 are respectively the box cover of the second box body 32 and the first box body 22. The purpose of arranging the position of the related box cover is that, for the battery module 31, the wiring port, the switch module and the indication module are generally arranged at the front end of the battery module 31. The second box cover 33 of the second box body 32 is arranged on the side, and the side of the second box body 32 with the second box cover 33 can be used as the front side. After the battery module 31 is placed into the second box body 32 from the position of the second box cover 33, the above switch module and indication module are exposed at the position of the second box cover 33 of the second box body 32. In this application, the second module wiring, temporary manual control and the running state of the battery module 31 can be obtained very conveniently. For the control module 24, a plurality of wiring terminals are generally arranged on the side. The first box cover 21 is arranged on the top of the first box body 22. After the first box cover 21 is opened and the control module 24 is placed into the first box body 22 from the top of the first box body 22, the wiring operation of the control module 24 can be completed in the gap between the control module 24 and the inner wall of the first box body 22. In summary, the position of the related box cover in the application is arranged to ensure the convenience of installing, controlling and maintaining the control module and the battery module 31.

The outer surface of the first box body 22 is provided with a fin heat sink 25. In the application, the ventilation window 35 and the fin heat sink 25 are respectively used to solve the problem of heat dissipation of the inside of the second box body 32 and the first box body 22. For the characteristics that the battery module 31 generates less heat under normal circumstances and has good water vapor protection ability, the ventilation window is used to realize the air convection in the second box body 32 to achieve the purpose of heat dissipation. For the characteristics that the control module 24 has relatively large heat dissipation, reliability and life which are easily affected by the surrounding environment, the fin heat sink 25 is used to increase the heat dissipation area of the surface of the first box body 22 to achieve the purpose of heat dissipation, and the control module 24 is arranged in a closed space to maintain the reliability of the control module 24. At the same time, for the characteristics that the low-voltage treatment equipment tower is not convenient to maintain, the application does not use a convection fan when solving the heat dissipation problem, which can effectively reduce the failure rate of the low-voltage treatment equipment and optimize its maintenance-free nature.
