Description

Technical Field

[0001] The utility model relates to the technical field of outdoor energy storage cabinet design, in particular to an outdoor energy storage busbar cabinet. Background Technique

[0002] With the rapid development of power systems and new energy applications, busbar cabinets, as key equipment, have been widely used in photovoltaic power generation, energy storage systems, and power distribution. The main function of a busbar cabinet is to converge multiple current sources into a single path and achieve effective transmission and distribution of current through protection devices and control devices. However, existing busbar cabinet technologies still have certain limitations in structural design and practical applications and cannot fully meet the requirements of efficient and flexible current management.

[0003] Currently, the widely used integrated busbar cabinets in the market usually place all components in a single cabinet and install each electrical component through a structure supported by beams and columns. The advantage of this design is a relatively high degree of functional integration, which can achieve the function of current convergence and distribution for one input and one output. However, the busbar cabinets of existing technologies have exposed some significant disadvantages during use.

[0004] Existing busbar cabinets need to accommodate a large number of electrical components such as circuit breakers and busbars inside. Their structural design is often relatively complex. This complexity not only increases the manufacturing cost and design difficulty but also brings challenges to later installation and maintenance. In addition, the internal space of the busbar cabinet is limited, and there are great restrictions when arranging large-current components. Especially when high-power equipment needs to be installed, the existing design cannot effectively utilize the space, resulting in inconvenient overall installation. Since the existing technology has not been optimized for the cabinet size in design, the shape of the busbar cabinet is relatively large, occupying a relatively large physical space. Especially in occasions where multiple busbar cabinets need to be installed, the space efficiency is low. Content of the Utility Model

Specific embodiments

[0033] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the embodiments and the drawings. The illustrative embodiments and descriptions of the present utility model are only used to explain the present utility model and are not intended to limit the present utility model.

[0034] Embodiment 1

[0035] Referring to Figures 1 - 5 , an outdoor energy storage busbar cabinet includes a busbar cabinet body and a busbar device. The busbar device is arranged in the busbar cabinet body. The busbar cabinet body includes a top cover 5, side plates 6, a bottom plate 7 and a door panel 8. The top cover 5 is arranged on the top of the side plates 6. The bottom plate 7 is arranged at the bottom of the side plates 6. The side plates 6 are of a U - shaped structure. A door panel 8 is arranged at the opening of the side plates 6. The top cover 5, side plates 6 and bottom plate 7 form a semi - enclosed cabinet that extends vertically in the up - down direction. The cabinet is designed to have a vertically extending structure, effectively utilizing the vertical space, facilitating the installation of multiple components within a limited floor area. The vertical space can arrange the equipment in layers, reasonably layout the equipment, and optimize the space utilization efficiency. Among them, the top cover 5 is located at the top of the cabinet, and the side plates 6 and bottom plate 7 form a support frame, with a stable overall structure, suitable for outdoor environments. The U - shaped structure enhances the support strength of the cabinet and provides space for the layout and operation of internal equipment, while facilitating the maintenance and installation of the equipment. One side of the cabinet is movably connected to one side of the door panel 8 through a hinge, and a door lock is arranged on the other side of the cabinet. The door lock is connected to the other side of the door panel 8 by a lock catch. Through the design of the hinge and the door lock, the door panel 8 can be flexibly opened and closed and fixed, ensuring that the cabinet is in a closed state during normal operation, improving the protection and safety of the equipment.

[0036] A preferred way is that the busbar cabinet body includes a bottom auxiliary plate 9. The bottom auxiliary plate 9 is arranged on the bottom plate 7 and is located at the opening of the side plate 6. The door panel 8 is located above the bottom auxiliary plate 9. The bottom auxiliary plate 9 is equivalent to adding an additional support structure on the bottom plate 7, which helps to improve the overall strength and load-bearing capacity of the cabinet body. Especially in the outdoor environment, the busbar cabinet has to bear various physical stresses. Setting the bottom auxiliary plate 9 can enhance the structural rigidity of the cabinet body and ensure its stability during long-term use. The door panel 8 is located above the bottom auxiliary plate 9. When the door panel 8 is opened, the bottom auxiliary plate 9 can play a role in isolating the equipment inside the cabinet, preventing dust or debris on the ground from directly entering the inside of the busbar cabinet, ensuring that the internal components are not directly affected by the external environment during maintenance and overhaul, and at the same time reducing the intrusion of external air flow and moisture, further improving the moisture-proof and dust-proof performance inside the cabinet body, thereby extending the service life of the internal electrical equipment.

[0037] In this embodiment, installation columns 10 are provided in the busbar cabinet body. There are 3 installation columns 10. The 3 installation columns 10 are arranged at intervals on the bottom plate 7. The installation columns 10 are arranged at intervals and only 3 columns are used to support the equipment installation on the back of the cabinet body, optimizing the space utilization inside the cabinet body, avoiding excessive columns occupying space, and leaving more installation space for components such as guide rails, busbar copper row busbars 14 and busbars 14. The installation columns 10 are all located on the back of the busbar cabinet body. One side of the installation column 10 is fixedly connected to the back of the side plate 6. On the other side of the installation column 10, guide rails, busbar copper row busbars 14 and busbars 14 are installed. Although only 3 installation columns 10 are used, one side of the column is fixedly connected to the back of the side plate 6, and the other side supports equipment such as guide rails, busbar copper row busbars 14 and busbars 14. Through this connection, it is ensured that each column is supported by the side plate 6, thus forming a relatively stable structure. Reducing the column structure can leave a relatively large operating space for the layout of the internal components of the cabinet body, facilitating maintenance and repair operations, reducing the inconvenience caused by narrow space during daily maintenance, and at the same time reducing the weight of the entire cabinet body. For outdoor energy storage equipment, the equipment weight is an important consideration factor in installation and transportation.

[0038] The installation column 10 is successively fixed with a first guide rail 11, a second guide rail 12, a third guide rail 13, a busbar 14, a fourth guide rail 15, a fifth guide rail 16, a first busbar copper row busbar 17, a second busbar copper row busbar 18, a third busbar copper row busbar 19, and a fourth busbar copper row busbar 20 from bottom to top. Both ends of the first guide rail 11 are respectively fixed to 2 adjacent installation columns 10 through insulator brackets 24. Both ends of the busbar 14 are respectively fixed to 2 non-adjacent installation columns 10 through insulator brackets 24. Both ends of the fourth guide rail 15 and the fifth guide rail 16 are respectively fixed to 2 non-adjacent installation columns 10 through insulator brackets 24. Both ends of the first busbar copper row busbar 17, the second busbar copper row busbar 18, the third busbar copper row busbar 19, and the fourth busbar copper row busbar 20 are fixed to 2 non-adjacent installation columns 10 through busbar copper row 21 insulator brackets 24. The guide rails and the busbar copper row busbar 14 are fixed to the installation column 10 through insulator brackets 24, effectively achieving electrical isolation and preventing potential safety hazards caused by current short circuits or electric leakage. Each busbar copper row busbar 14 is fixed to a different installation column 10 through an insulating bracket, ensuring the safety and stability of electrical connections and avoiding short circuits or interference between electrical devices. Among them, the busbar 14 is responsible for collecting current and transmitting it to each circuit breaker and energy storage device. Through such a layout, the role of the busbar 14 in the system is maximized. In addition, dispersing the devices on multiple guide rails and at different height positions can improve the heat dissipation efficiency between the devices and avoid local overheating problems caused by device concentration.

[0039] Specifically, a surge protector 4 is fixedly arranged on the first guide rail 11, a first power supply circuit breaker 2 and a second power supply circuit breaker 3 are fixedly arranged on the second and third guide rails 13, a main power supply circuit breaker 1 is fixedly arranged on the fourth guide rail 15 and the fifth guide rail 16, and [there is something] fixedly arranged on the busbar 14. The surge protector 4 is fixed on the first guide rail 11 to ensure that it can protect the system immediately when the current surges and prevent surges from damaging other key devices in the system. The main power supply circuit breaker 1 is fixed on the fourth and fifth guide rails 16 to ensure its stable installation as a core device and reduce the influence of external factors on its operation.

[0040] The power supply side of the main power supply circuit breaker 1 is connected to 4 busbar copper bars 21. The 4 busbar copper bars 21 are respectively fixed to the first busbar copper bar bus 17, the second busbar copper bar bus 18, the third busbar copper bar bus 19, and the fourth busbar copper bar bus 20 through insulators 26. The 4 busbar copper bars 21 are fixed to the bus 14 through insulators 26. Fixing the busbar copper bars 21 to the first to fourth busbar copper bar buses 20 and the bus 14 through insulators 26 is to transmit the current of the main power supply circuit breaker 1 to different buses 14 respectively, ensuring that the current is evenly distributed to each branch, and further transmitting the current to other devices through the bus 14. The setting of the bus 14 ensures the functions of current collection and shunting, and can effectively distribute or concentrate the current between multiple lines, preventing current overload or uneven transmission.

[0041] The output end of the main power supply circuit breaker 1 is connected to 4 copper bars 22. The 4 copper bars 22 are respectively connected to the first branch bus 14, the second branch bus 14, the third branch bus 14, and the fourth branch bus 14. The two ends of the bus 14, the first branch bus 14, the second branch bus 14, the third branch bus 14, and the fourth branch bus 14 are sequentially connected through insulators 26. The output end of the main power supply circuit breaker 1 is connected to 4 copper bars 22, which are respectively connected to the first, second, third, and fourth branch buses 14, so that the current can be further distributed from the main power supply circuit breaker 1 to multiple branches, forming a multi-way output structure. By independently transmitting the current through each branch, the needs of different electrical equipment can be met. At the same time, since the current is dispersed to multiple branches, the current load on a single line is reduced, and the risk of damage during overheating or sudden current increase is reduced.

[0042] Each copper bar 22 or bus 14 is fixed through an insulator bracket 24, ensuring electrical isolation between current channels, improving the safety of the system, and preventing phenomena such as current short circuit or arc discharge. The insulator bracket 24 also plays a supporting role, ensuring the stability of the copper bars 22 and the bus 14 and the rationality of the layout, and reducing the impact of vibration or other external forces on the electrical connection.

[0043] The input end of the first backup power supply circuit breaker 2 is connected to 4 branch copper bars 23. The 4 branch copper bars 23 are respectively connected to the first branch bus 14, the second branch bus 14, the third branch bus 14, and the fourth branch bus 14. The input end of the second backup power supply circuit breaker 3 is connected to 4 branch copper bars 23. The 4 branch copper bars 23 are respectively connected to the first branch bus 14, the second branch bus 14, the third branch bus 14, and the fourth branch bus 14, so that the two power supplies respectively obtain current from the bus 14, ensuring that the two currents can work independently or in parallel, realizing two independent current outputs, and improving the flexibility and redundancy of the system through the multi-branch bus 14.

[0044] In a preferred embodiment, the top cover 5 is provided with louvers, and the front of the bottom auxiliary plate 9 is provided with louvers.

[0045] Embodiment 2

[0046] Reference Figure 6 , on the basis of Embodiment 1, this embodiment proposes an electrical connection relationship of an outdoor energy storage busbar cabinet.

[0047] An outdoor energy storage busbar cabinet includes a busbar cabinet body and a busbar device. The busbar device is arranged in the busbar cabinet body. The busbar device includes a main power supply breaker 1, a first secondary power supply breaker 2, a second secondary power supply breaker 3, and a surge protector 4. The model of the main power supply breaker 1 is SM8630M4P230630(630A), the models of the first secondary power supply breaker 2 and the second secondary power supply breaker 3 are SM8250M4P230250(250A), and the model of the surge protector 4 is NXSCB-II 100H. The power supply side of the main power supply breaker 1 is electrically connected to the grid connection cabinet. The output end of the main power supply breaker 1 is respectively electrically connected to the input ends of the first secondary power supply breaker 2, the second secondary power supply breaker 3, and the input end of the surge protector 4. The output ends of the first secondary power supply breaker 2 and the second secondary power supply breaker 3 are respectively electrically connected to the energy storage cabinet. The surge protector 4 is connected to the grounding bar 27. The main power supply breaker 1 is the main input control device of the entire system and is responsible for receiving power from the grid connection cabinet. The power supply side of the main power supply breaker 1 is connected to the grid connection cabinet and can handle a maximum current of 630A, which is suitable for high-power input. The models of the two secondary power supply breakers are the same, and they respectively handle the current output from the main power supply breaker 1, allowing the system to flexibly shunt according to requirements. Each secondary power supply breaker can carry a maximum current of 250A.

[0048] One input and two outputs means that through one input, that is, the main power supply breaker 1, it outputs to two different secondary power supply breakers, namely the first secondary power supply breaker 2 and the second secondary power supply breaker 3 at the same time, to achieve current shunting. When the main power supply breaker 1 receives power, the current enters the first secondary power supply breaker 2 and the second secondary power supply breaker 3 through its output end respectively. These two secondary power supply breakers supply power to their respective energy storage cabinets and can work independently to achieve two-way output.

[0049] Two inputs and one output means that two power inputs can jointly pass through the main power supply breaker 1 and finally output to the same load. In a specific situation, assuming that the input ends of the first and second secondary power supply breakers 3 are simultaneously connected to two independent power sources, such as power sources from two grid connection cabinets. When it is necessary to combine the outputs of these two power sources, the current can be collected to one output end through the main power supply breaker 1.
