Description

Technical Field

[0001] The present utility model mainly relates to the technical field of electrical equipment, and specifically relates to a supercapacitor discharging device with adjustable discharge load. Background Art

[0002] Electrical equipment is a general term for equipment composed of electrical components used for power generation, power transmission, power transformation, power distribution, power utilization, electrical control and other related functions. It covers various types of components from large-scale generators and transformers to small resistors, capacitors and other components. Its core function is to realize the conversion, transmission, storage or control of electric energy.

[0003] In this category, as a new type of energy storage electrical equipment, supercapacitors have become an important part of the field of electric energy storage by virtue of their extremely high power density, fast charge and discharge capacity and ultra-long cycle life. They store electric energy through the electric double layer formed between the electrode and the electrolyte. They not only have the characteristic of fast response of capacitors, but also have an energy storage scale close to that of batteries, and are widely used in scenarios requiring instantaneous high-power output or fast energy recovery. Discharging devices are key components matched with energy storage equipment such as supercapacitors. Their main function is to safely, stably and controllably release the electric energy stored in the supercapacitor according to actual requirements, and ensure that the discharging process meets the power requirements of the load through reasonable design of circuit structure and control logic. The load resistance of traditional devices is mostly in fixed configuration, and its resistance value and power parameters are difficult to adjust flexibly according to the capacity and voltage level of supercapacitors. When facing supercapacitors of different specifications, it is necessary to replace the whole set of devices or carry out complex circuit modification, which is cumbersome to operate, poor in adaptability, and difficult to meet diversified discharge requirements. Meanwhile, the power and voltage bearing range of a single device is limited. When dealing with large-capacity or high-voltage supercapacitor energy storage equipment, it is difficult to realize capacity expansion through simple combination, and the circuit connection mode is fixed. Multiple sets of devices require complex external wiring for cooperative work, lacking a unified standardized interface, which is prone to connection errors and affects the stability and safety of discharge.

The series copper busbar and the upper and lower sets of parallel copper busbars form a series circuit.

[0011] Furthermore, when the series copper busbar is horizontally installed between the main positive copper busbar, the fuse, and the main negative copper busbar, on the side of the main positive copper busbar, one end of the series copper busbar is connected to the main positive copper busbar and the fuse, and the other end is connected to the input terminal of the parallel copper busbar. On the side of the main negative copper busbar, one end of the series copper busbar is connected to the output terminal of the parallel copper busbar, and the other end is connected to the main negative copper busbar.

At the same time, the multi-side cabinet door design, combined with the top and bottom ventilation holes and fan integrated module to form a three-dimensional heat dissipation channel, not only ensures the convenience of multi-directional operation, but also efficiently dissipates the heat generated by the load resistors, achieving a unity of structural flexibility, operational convenience and efficient heat dissipation.

[0016] 2. The copper busbar integrated module of the device can flexibly realize the "series-parallel" circuit mode conversion by switching between vertical and horizontal installation of series copper busbars. With the adjustment of the number of load resistors, the discharge power can be precisely controlled over a wide range to meet the needs of supercapacitors of different capacities. The fuses connected in series in the total positive and total negative copper busbar lines provide reliable overcurrent protection.

[0022] Please refer to the appendix carefully. Figure 1-4 A supercapacitor discharge device with adjustable discharge load includes a power distribution cabinet 1, a resistor integrated module 2, a fan integrated module 3, and a copper busbar integrated module 4. The copper busbar integrated module 4 is detachably installed on one side of the power distribution cabinet 1, and the resistor integrated module 2 is detachably installed on the other side of the power distribution cabinet 1. Multiple resistor integrated modules 2 are distributed at equal intervals along a preset direction inside the power distribution cabinet 1 and are adjacent to the copper busbar integrated module 4. The fan integrated module 3 is installed below the resistor integrated module 2.

[0023] The copper busbar integrated module 4 includes an input copper busbar fixing bracket 5, an output copper busbar fixing bracket 6, a fuse 7, a main positive copper busbar 8, a main support 9, a main negative copper busbar 10, a parallel copper busbar 11, and a series copper busbar 12. The input copper busbar fixing bracket 5 and the output copper busbar fixing bracket 6 are both fixed on the main support 9. The main positive copper busbar 8 and the main negative copper busbar 10 are symmetrically distributed at both ends of the same side of the main support 9. The parallel copper busbar 11 is fixed between the main positive copper busbar 8 and the main negative copper busbar 10. The parallel copper busbar 11, the main positive copper busbar 8, and the main negative copper busbar 10 together form a parallel circuit composed of multiple load resistors connected in parallel. There are multiple sets of parallel copper busbars 11, each set is divided into upper and lower parts. The upper part is the input parallel copper busbar, and the lower part is the output parallel copper busbar. A fuse 7 is connected in series in each line from the main positive copper busbar 8 to the main negative copper busbar 10.

[0024] In this embodiment, as Figure 1 As shown, the front, back, left and right sides of the power distribution cabinet 1 are equipped with cabinet doors, and the top and bottom are equipped with ventilation holes. The fan integration module 3 works in conjunction with the ventilation holes at the bottom of the power distribution cabinet 1 to form a heat dissipation air duct from bottom to top.

[0025] With the above structure, the power distribution cabinet 1 has multiple cabinet doors on each side, which facilitates opening and closing operations from multiple directions, providing convenience for the installation, inspection and maintenance of internal modules. Ventilation holes are opened at the top and bottom, which, together with the fan integrated module 3, form a bottom-up heat dissipation air duct, which can quickly dissipate the heat generated by the load resistor 16 during operation, taking into account both ease of operation and high heat dissipation efficiency, and improving the practicality of the device.

[0026] In this embodiment, as Figure 3 As shown, the resistor integrated module 2 mainly consists of an insulating sleeve 15, load resistors 16, connecting rods 17 and resistor integrated brackets 18. Multiple load resistors 16 are passed through and fixed between the inner walls of the resistor integrated brackets 18 by the connecting rods 17. Adjacent load resistors 16 are separated by insulating sleeves 15. Load resistor input terminal connection 1601 and load resistor output terminal connection 1602 are respectively opened on one side of the load resistor 16.

[0027] Through the above structure, the connecting rod 17 is fixed through to ensure that multiple load resistors 16 are installed firmly. Multiple load resistors 16 can be installed conveniently according to actual discharge requirements, further enhancing the device's adaptability to different discharge scenarios. This achieves a balance between structural stability, electrical safety, and functional flexibility. The insulating sleeve 15 spacing can prevent leakage interference from adjacent resistors and ensure operational safety.

[0028] In this embodiment, as Figure 2 As shown, the series copper busbars 12 are installed vertically or horizontally.

[0029] When the series copper busbar 12 is vertically installed between the upper and lower sets of parallel copper busbars 11, one end of it is connected to the output terminal of the upper set of parallel copper busbars 11, and the other end is connected to the input terminal of the lower set of parallel copper busbars 11. The series copper busbar 12 and the upper and lower sets of parallel copper busbars 11 form a series circuit.

[0030] When the series copper busbar 12 is horizontally installed between the main positive copper busbar 8, the fuse 7 and the main negative copper busbar 10, on the side of the main positive copper busbar 8, one end of the series copper busbar 12 is connected to the main positive copper busbar 8 and the fuse 7, and the other end is connected to the input terminal of the parallel copper busbar 11. On the side of the main negative copper busbar 10, one end of the series copper busbar 12 is connected to the output terminal of the parallel copper busbar 11, and the other end is connected to the main negative copper busbar 10. The series copper busbar 12 and the parallel copper busbar 11 located in the lower group form a parallel circuit.

[0031] With the above structure, each line from the total positive copper busbar 8 to the total negative copper busbar 10 is connected in series with a fuse 7, which can quickly melt and cut off the circuit when the current is abnormal, providing reliable safety protection for the entire device. The series copper busbar 12 connects two sets of parallel copper busbars 11 in series by vertical installation and connects them to the total negative copper busbar 10 by horizontal installation to form a parallel circuit. The circuit connection method can be flexibly changed to realize the increase or decrease of the total resistance and the adjustment of the current, adapting to different voltage and discharge current requirements. It has both safety and adjustment flexibility, improving the applicability and reliability of the device.

[0032] In this embodiment, as Figure 2 As shown, in the copper busbar integrated module 4, the input copper busbar fixing bracket 5 and the output copper busbar fixing bracket 6 are arranged in pairs along the length of the total support 9. The input copper busbar fixing bracket 5 is provided with An point 13 corresponding to the load resistor input terminal connection 1601, and the output copper busbar fixing bracket 6 is provided with Bn point 14 corresponding to the load resistor output terminal connection 1602.

[0033] Through the above structure, the corresponding setting of An point and Bn point ensures accurate connection when load resistor 16 is connected, reducing connection errors. At the same time, this arrangement method facilitates the quick addition or removal of load resistors as needed, flexibly adjusts the circuit configuration, and improves the assembly efficiency and expansion adaptability of the device.

[0034] In this embodiment, as Figure 2 As shown, point An 13 and point Bn 14 correspond one-to-one. The load resistor 16 is electrically connected to point An 13 via a wire through the load resistor input terminal 1601. The load resistor 16 is electrically connected to point Bn 14 via a wire through the load resistor output terminal 1602.

[0035] With the above structure, the number and combination of load resistors 16 can be flexibly selected through the corresponding interface, easily realizing discharge power adjustment and adapting to different discharge requirements.

[0036] In this embodiment, as Figure 1 , Figure 2 Diagram and Figure 4 As shown, multiple sets of distribution cabinets 1 are connected in series or in parallel through a total positive copper busbar 8 and a total negative copper busbar 10. When connected in series, the total negative copper busbar 10 of the previous set of distribution cabinets 1 is electrically connected to the total positive copper busbar 8 of the next set of distribution cabinets 1. When connected in parallel, the total positive copper busbars 8 of each set of distribution cabinets 1 are electrically connected to each other, and the total negative copper busbars 10 are electrically connected to each other.

[0037] Through the above structure, multiple sets of distribution cabinets 1 can be combined in series and parallel under a modular structure via positive copper busbars 8 and total negative copper busbars 10. In series combination, the total negative copper busbar 10 of the previous set of distribution cabinets 1 is electrically connected to the total positive copper busbar 8 of the next set of distribution cabinets 1, which can quickly increase the discharge voltage. In parallel combination, the total positive copper busbars 8 of each set of distribution cabinets 1 are electrically connected to each other, and the total negative copper busbars 10 are electrically connected to each other, which can effectively enhance the current carrying capacity. It can flexibly adapt to external supercapacitor energy storage devices with different capacity, voltage and current requirements, greatly expanding the application scenarios. Moreover, the connection method is simple and direct, which is convenient for quick adjustment according to actual working conditions, ensuring efficient and stable discharge process.

[0038] The specific operating procedure of this utility is as follows: First, the external supercapacitor energy storage device needs to be connected to the copper busbar integrated module 4 of the discharge device. Specifically, the positive terminal of the supercapacitor energy storage device is connected to the main positive copper busbar 8, and the negative terminal is connected to the main negative copper busbar 10. At this time, the fuse 7 in the copper busbar integrated module 4 will protect each line from the main positive copper busbar 8 to the main negative copper busbar 10. When the current in the line increases abnormally, the fuse 7 will melt and cut off the circuit to prevent equipment damage and safety accidents.

[0039] Next, select the number and connection method of the load resistors 16 participating in the work in the resistor integration module 2 according to the actual needs. Each load resistor 16 has a load resistor input terminal connection 1601 and a load resistor output terminal connection 1602 on one side. They are electrically connected to the corresponding An point 13 on the input copper busbar fixing bracket 5 and the corresponding Bn point 14 on the output copper busbar fixing bracket 6 in the copper busbar integration module 4 through wires.

[0040] The discharge power can be adjusted by changing the number of load resistors 16 connected to the circuit. When the number of load resistors 16 decreases, the discharge power decreases; when the number of load resistors 16 increases, the discharge power increases.

[0041] During the discharge process, the circuit structure can be changed by adjusting the installation method of the series copper busbar 12 according to the voltage of the external supercapacitor energy storage device. When the voltage of the external supercapacitor energy storage device is high, the series copper busbar 12 is vertically installed between the upper and lower sets of parallel copper busbars 11, so that one end of the series copper busbar 12 is connected to the output terminal of the upper set of parallel copper busbars 11 and the other end is connected to the input terminal of the lower set of parallel copper busbars 11. At this time, the upper and lower sets of parallel copper busbars 11 form a series circuit through the series copper busbar 12, which increases the total resistance of the circuit, reduces the discharge current, and increases the discharge time, ensuring a stable and safe discharge process.

[0042] When the voltage of the external supercapacitor energy storage device is within the preset range and a larger discharge current is required, the series copper busbar 12 is horizontally installed between the main positive copper busbar 8, the fuse 7, and the main negative copper busbar 10. On the side of the main positive copper busbar 8, one end of the series copper busbar 12 is connected to the main positive copper busbar 8 and the fuse 7, and the other end is connected to the input terminal of the parallel copper busbar 11. On the side of the main negative copper busbar, one end of the series copper busbar 12 is connected to the output terminal of the parallel copper busbar 11, and the other end is connected to the main negative copper busbar 10. At this time, the series copper busbar 12 and the lower parallel copper busbar 11 form a parallel circuit, the total circuit resistance decreases, the discharge current increases, and the discharge time decreases.

[0043] During the discharge period, the fan integrated module 3 starts to work. Since the top and bottom of the power distribution cabinet 1 are equipped with ventilation holes, the fan integrated module 3 and the ventilation holes at the bottom of the power distribution cabinet 1 cooperate to form a heat dissipation air duct from bottom to top.

[0044] When the load resistor 16 in the resistor integrated module 2 is working, it will generate heat. This heat dissipation duct can dissipate the heat in time, ensuring that the resistor integrated module 2 and the entire discharge device work in a suitable temperature environment, and preventing the equipment performance and service life from being affected by excessive temperature.

[0045] When multiple sets of distribution cabinets 1 need to work together to adapt to different discharge requirements, multiple sets of distribution cabinets 1 can be connected in series or in parallel through copper busbars: When connected in series, the total negative copper busbar 10 of the first set of distribution cabinet 1 is electrically connected to the total positive copper busbar 8 of the second set of distribution cabinet 1. After the combination, the system discharge voltage increases, which is suitable for external supercapacitor energy storage equipment that requires a higher discharge voltage.

[0046] When connected in parallel, the total positive copper busbars 8 of each group of distribution cabinets 1 are electrically connected to each other, and the total negative copper busbars 10 of each group of distribution cabinets 1 are electrically connected to each other. After the combination, the current carrying capacity of the system is enhanced, which is suitable for external supercapacitor energy storage equipment that requires a large discharge current.

[0047] Through this flexible combination, the discharge device can be adapted to external supercapacitor energy storage devices with different capacities, voltages and current requirements, achieving efficient and safe discharge operation.

[0048] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
