Abstract
Description
Technical Field
[0001] This utility model relates to the field of standardized distribution radio area technology, and in particular to an integrated intelligent platform device. Background Technology
[0002] In modern power systems, the application of test bench technology is becoming increasingly widespread; however, existing technologies have many problems. Traditional high-voltage equipment on test benches, such as disconnecting switches, corrosion-resistant porcelain insulators, and drop-out fuses, is typically installed at a height of more than 3 meters above the ground using a crossarm mounting method. While this configuration ensures equipment operation to some extent, it also introduces safety hazards such as increased risk of electric shock to personnel and short circuits caused by hanging objects. Furthermore, the equipment occupies a large area and has a long construction period, causing numerous inconveniences for the construction and maintenance of the power system.
[0003] Of particular note is the significant defect in the low-voltage configuration of traditional distribution boxes. The low-voltage distribution box is installed independently below the transformer, measuring approximately 1.4 meters in length, 1.5 meters in height, and 0.8 meters in depth, occupying about 1.2 square meters. Due to its low installation location, the distribution box is highly susceptible to rainwater immersion, especially in urban flooding. This can not only damage the equipment but also potentially lead to serious safety accidents. Furthermore, the low-position installation of the distribution box increases the risk of electric shock to personnel.
[0004] In summary, existing platform technology has shortcomings in terms of safety, space utilization efficiency, and ease of construction. Utility Model Content

[0031] Please see Figures 1 to 6 The integrated intelligent test bench equipment includes a low-voltage module 10, a transformer module 20, and a test bench 30. Both the low-voltage module 10 and the transformer module 20 are mounted on the test bench 30. The low-voltage module 10 and the transformer module 20 are connected by plug-in components to achieve modular assembly.
[0032] In this technical solution, the low-voltage module 10 and the transformer module 20 are integrated into a single intelligent rack unit through modular assembly, effectively reducing the overall size of the equipment and improving land use efficiency, thus solving the problem of the large footprint of traditional rack units 30. Simultaneously, modular assembly reduces on-site construction workload, allowing much work to be completed in the factory beforehand, shortening the construction cycle and improving efficiency. Furthermore, the rack unit 30 enclosure is mounted at the same height as the ground surface, avoiding safety hazards caused by rainwater immersion and urban flooding, and reducing the risk of electric shock. The modules are connected using connectors, reducing the need for terminal fabrication and installation, lowering the probability of flashover and short-circuit faults, and thus reducing maintenance costs. This technical solution not only efficiently utilizes space but also improves construction convenience, enhances equipment safety and environmental adaptability, and reduces maintenance costs through intelligent management, thereby improving equipment reliability and stability.
[0033] In one embodiment, the platform 30 is installed at a height of 2.6m above the ground. Both the low-voltage module 10 and the transformer module 20 can be fixed to the platform 30 by bolts, welding, or other methods. In this case, the low-voltage module 10 and the transformer module 20 are set at the same height as the ground. When repairing one module, it is not necessary to cross the other module in the vertical direction, thereby reducing the risk of electric shock. The transformer module 20 has a high-voltage side and a low-voltage side. The high-voltage side is connected to the high-voltage line through an insulated cable. After the transformer module 20 transforms the voltage, the low-voltage side is used to output low-voltage current, such as 220V AC mains power, 380V industrial power, etc. At the same time, the low-voltage compartment and the transformer compartment are connected by a plug-in assembly to achieve electrical conduction. Specifically, the plug-in assembly includes a busbar, a connector, and an interface. The busbar is the core component of the plug-in assembly, typically made of copper or aluminum, which has good conductivity and mechanical strength. The busbar can be designed as flat, rectangular, or other suitable shapes to ensure efficient and safe current transmission. One end of the busbar is connected to the low-voltage side of the transformer module 20, and the other end is connected to the low-voltage module 10. Connectors and interfaces ensure a stable connection between the busbar and the low-voltage room equipment, while also facilitating equipment disassembly and maintenance. Connectors typically have good electrical contact performance and mechanical stability, and can withstand certain tensile and compressive forces to ensure connection reliability. Understandably, the plug-in assembly undergoes necessary insulation treatment to ensure the safety of the electrical connection. Current transmission is achieved through the plug-in assembly.
[0034] In one embodiment, the transformer module 20 includes a high-voltage unit and a transformer substation. The high-voltage unit includes a high-voltage load switch and a plug-in fuse. The transformer substation is equipped with a transformer box 21, which houses an oil-immersed power transformer 22. The high-voltage load switch and the plug-in fuse are located inside the transformer box 21, wherein the high-voltage load switch and the plug-in fuse are connected in series, and the plug-in fuse is connected to the high-voltage side of the oil-immersed power transformer 22. The transformer box 21 is an insulated structure, and the insulated cable for connecting the high-voltage line passes through the transformer box 21 and connects to the high-voltage side of the oil-immersed power transformer 22. The high-voltage load switch and plug-in fuse between the lines are used to achieve electrical protection. Specifically, the high-voltage incoming line is connected to the incoming terminal of the high-voltage load switch, the outgoing terminal of the high-voltage load switch is connected to the fuse, and the outgoing terminal of the fuse is connected to the high-voltage side of the transformer. When an overload or short circuit occurs on the high-voltage side of the transformer, the fuse blows, cutting off the fault current. At the same time, the load switch receives the fuse's blow-off action signal (through a mechanical interlocking device) and automatically trips to achieve dual protection. In this process, because the high-voltage load switch and plug-in fuse are located inside the transformer box 21, the risk of exposure is eliminated, reducing the frequency of electric shock and short circuits caused by hanging objects.
[0035] Furthermore, the low-voltage side of the oil-immersed power transformer 22 is equipped with an emergency power input port, which is used to quickly connect to a backup power source in case of emergency. This design allows for rapid connection to a generator or other backup power source during main power failure or equipment maintenance to ensure the continuity of power supply.
[0036] In one embodiment, please refer to Figure 4The low-voltage module 10 includes a low-voltage box 11, a low-voltage disconnect switch 12, and a low-voltage intelligent switch 13. The low-voltage disconnect switch 12 and the low-voltage intelligent switch 13 are electrically connected and both are housed within the low-voltage box 11. The low-voltage disconnect switch 12 is electrically connected to the low-voltage side of the transformer module 20. The low-voltage box 11 serves as the outer casing of the low-voltage module 10, housing and protecting the internal electrical equipment. It is typically made of metal or insulating materials, providing excellent protection against external objects and damage to the internal electrical equipment. The low-voltage disconnect switch 12 is installed within the low-voltage box 11 and located at the input terminal of the low-voltage module 10, used to disconnect the low-voltage circuit and ensure the circuit is properly closed. For safety during maintenance, the low-voltage disconnect switch 12 is connected to the low-voltage side of the transformer module 20 via a busbar or cable, transmitting current from the transformer to the low-voltage module 10. The low-voltage intelligent switch 13 is also installed in the low-voltage box 11, connected to the output terminal of the low-voltage disconnect switch 12, and is used to provide multiple protection functions, such as overvoltage, undervoltage, overload and short-circuit protection. The low-voltage disconnect switch 12 and the low-voltage intelligent switch 13 are connected via a busbar or cable to achieve electrical connection. The low-voltage disconnect switch 12 is used to transmit current from the low-voltage side of the transformer module 20 to the low-voltage module 10, and the low-voltage intelligent switch 13 is used to detect the low-voltage disconnect switch 12 to achieve electrical protection.
[0037] Further, please refer to Figure 4 The low-voltage module 10 also includes a low-voltage outgoing circuit breaker 14. The low-voltage outgoing circuit breaker 14 is equipped with a health detection unit and is connected to the low-voltage disconnect switch 12. The health detection unit includes a high-precision sensor and a high-performance processor. The health detection unit is configured to collect and analyze electrical parameters, thereby achieving high-precision acquisition and calculation of electrical parameters such as voltage, current, power, and temperature. It also provides multiple protection functions such as long delay, short delay, instantaneous, overvoltage, undervoltage, and zero-circuit protection. It also has rich electrical parameter curves, event records, and frozen data, providing accurate data support for intelligent distribution area line loss analysis, intelligent operation and maintenance, rapid fault location and diagnosis, etc., and providing early warning of low-voltage side operation problems in the distribution area, thereby improving the reliability of power supply to users. The low-voltage outgoing circuit breaker 14 is installed in the low-voltage box 11 and connected to the low-voltage disconnect switch 12. It further distributes the current from the low-voltage disconnect switch 12 to each load end and provides overvoltage, undervoltage, overload, and short-circuit protection functions.
[0038] In one embodiment, the low-voltage module 10 is also provided with a sensorless connection port for the generator vehicle. The sensorless connection port for the generator vehicle is located between the low-voltage disconnect switch 12 and the low-voltage intelligent switch 13. The low-voltage cable of the generator vehicle can be directly connected to the sensorless connection port while energized, so that the user has zero awareness of power outages during the entire process of power transfer from the generator vehicle. After the generator vehicle is energized and before it is energized and disconnected, the quasi-synchronous grid connection technology of the generator vehicle is applied to realize the grid connection of the generator vehicle and seamless switching of user load.
[0039] In one embodiment of this utility model, please refer to Figure 1 The integrated intelligent test bench device also includes a control module 40, which includes a gateway and a distribution transformer monitoring terminal. The gateway is communicatively connected to the distribution transformer monitoring terminal. The low-voltage side of the transformer module 20 is electrically connected to the distribution transformer monitoring terminal. In this embodiment, the gateway adopts an industrial-grade embedded computer that supports 4G / 5G, LoRaWAN, and Ethernet multi-mode communication, and has a built-in SIM card slot and encryption chip. The distribution transformer monitoring terminal integrates a voltage / current transformer, a temperature sensor, and an energy metering chip, and can be connected to the gateway via an RS485 bus. The voltage / current sampling line of the distribution transformer monitoring terminal is directly connected to the low-voltage side output terminal of the transformer module 20 to collect parameters such as voltage, current, and power factor in real time. Digital temperature sensors are arranged at the transformer oil temperature probe and the circuit breaker of the low-voltage module 10. The data is uploaded to the distribution transformer monitoring terminal via the Modbus RTU protocol, thereby realizing real-time monitoring, data analysis, and remote management of the transformer module 20.
[0040] In one embodiment, please refer to Figure 5 The integrated intelligent platform equipment is equipped with two low-voltage modules 10, which are located on both sides of the control module 40. Each low-voltage module 10 is equipped with a low-voltage intelligent outgoing switch to meet the power supply needs of the distribution area.
[0041] In one embodiment of this utility model, the transformer module 20 is further provided with a zinc oxide surge arrester. The zinc oxide surge arrester is gapless and is connected in parallel to the incoming side of the high-voltage load switch, directly connecting the phase line and the grounding grid, thereby protecting the integrated intelligent platform equipment from lightning and overvoltage damage.
[0042] Furthermore, both the low-voltage module 10 and the transformer module 20 are equipped with temperature sensors. The temperature sensors are used to detect temperature changes in the low-voltage module 10, the transformer module 20, and the connection between them. Specifically, the temperature sensors can be embedded in the fastening nuts of the cable terminals. By monitoring temperature changes in real time, the temperature sensors can promptly detect potential overheating problems, prevent malfunctions and accidents caused by overheating, and improve the safety of equipment operation. At the same time, the temperature sensors can promptly detect and handle abnormal temperature problems, which can reduce damage to the equipment caused by overheating and extend the service life of the equipment.
