Description

A U-shaped test stand for an on-board oil detection system Technical Field

[0001] This utility model relates to the field of power insulating oil analysis technology in the power industry, specifically to a U-shaped experimental platform for a vehicle-mounted oil detection system. Background Technology

[0002] Performance testing of insulating oil in power systems is an important means of fault diagnosis and hidden danger investigation of power equipment. The existing insulating oil testing mainly adopts the mode of on-site sampling and transportation to a fixed central laboratory for analysis. This mode has a long testing cycle and poor timeliness, which cannot meet the needs of emergency diagnosis of equipment faults. Moreover, the properties of oil samples are prone to change during long-distance transportation, resulting in distorted test results.

[0003] To address the issue of time-consuming transportation, staff have mounted testing equipment on vehicles for mobile testing operations. However, these mobile testing devices often suffer from incomplete functionality, typically possessing only single capabilities such as chromatographic or withstand voltage testing, and are unable to complete the full set of standard tests for insulating oil on-site. Furthermore, the internal space layout of existing mobile testing vehicles lacks scientific planning, with various testing instruments, auxiliary equipment, and safety facilities arranged haphazardly, resulting in low space utilization, long operational routes, and irregular equipment connections. Moreover, the equipment is easily damaged during transportation due to bumps, and there are safety hazards arising from inadequate hazard control during use. Therefore, there is an urgent need for a mobile insulating oil testing solution that can be quickly deployed to the site, is fully functional, operates stably, and has a rational layout.

[0004] Therefore, there is an urgent need for a U-shaped test platform for vehicle-mounted oil testing systems, which can scientifically integrate a complete set of insulating oil testing instruments and supporting facilities within the limited space of a vehicle, and realize the orderly arrangement of testing equipment. Summary of the Invention

[0005] To address the issues of low integration and unreasonable layout in existing vehicle-mounted oil and chemical testing systems, a U-shaped test bench for such systems is proposed. This bench includes test cabinets arranged in a U-shape, with placement slots on the tabletop within the U-shaped operating area to accommodate the entire testing device. It also incorporates a pneumatic and safety zone, a power distribution and energy storage zone, an environmental protection zone, and a storage zone, providing a foundation for comprehensive mobile testing.

[0006] To achieve the above objectives, this utility model proposes a U-shaped test bench for a vehicle-mounted oil and chemical testing system, including a mobile platform chassis and a box-shaped cabin mounted on the mobile platform chassis. The box-shaped cabin is equipped with multiple test cabinets, which enclose a U-shaped operating area along the side walls and rear of the box-shaped cabin. Each test cabinet includes a cabinet body and a tabletop, and a placement slot is provided on the tabletop. The placement slot has a square structure.

[0007] The compartment is also equipped with a gas passage and safety area, a power distribution and energy storage area, an environmental protection area and a storage area. The exterior of the compartment is equipped with an integrated auxiliary function structure, and the experimental cabinet located in the center of the U-shaped operating area is equipped with a central control and operation area.

[0008] Pipelines and wiring channels are pre-embedded inside the box-type cabin and experimental cabinet.

[0009] Furthermore, the U-shaped operating area includes a first long side, a second long side, and a connecting side. The placement slot at the position of the first long side is sequentially equipped with a fully automatic insulating oil analysis gas chromatograph, a host computer, a printer, an insulating oil acid value tester, and a tension tester.

[0010] The placement slot at the second long side position is sequentially equipped with a flash point tester, an insulating oil dielectric loss tester, a water-soluble acid value tester, an insulating oil withstand voltage tester, and a handwashing basin for experiments.

[0011] A trace moisture tester and a portable particle size analyzer are installed in the placement groove at the connection edge position.

[0012] The complete set of instruments for insulating oil testing is arranged in the placement slots on the first long side, the second long side, and the connecting side of the U-shaped operating area according to the testing process, forming a continuous testing operation zone. Operators can complete all testing items by following the U-shaped movement line without having to repeatedly turn back, which greatly improves the efficiency of on-site testing operations.

[0013] All testing instruments are placed in square slots on the tabletop, ensuring precise positioning and fixation of the equipment. This effectively prevents slippage and collisions during vehicle transportation, protecting delicate components and guaranteeing both transport safety and testing accuracy. Handwashing sinks are conveniently located near the various testing instruments to meet cleaning and rinsing needs during experiments, optimizing operational details and enhancing on-site convenience. A complete set of insulating oil testing instruments is integrated within the U-shaped operating area, enabling on-site completion of all standard testing items, including chromatography, acid value, dielectric loss, trace moisture, and particle size, completely resolving the limitation of traditional vehicle-mounted testing equipment with limited functionality.

[0014] Furthermore, the central control and operation area is equipped with a controller and a power distribution control cabinet. The controller is communicatively connected to a fully automatic insulating oil analysis gas chromatograph, a host computer, a printer, an insulating oil acid value tester, a tension tester, a flash point tester, an insulating oil dielectric loss tester, a water-soluble acid value tester, an insulating oil withstand voltage tester, a trace moisture tester, and a portable particle size analyzer.

[0015] The centralized control and power distribution design reduces the complexity of wiring connections between instruments, facilitates unified equipment debugging, fault diagnosis and daily maintenance, and reduces equipment operation and maintenance costs.

[0016] Furthermore, the gas path and safety zone are located on one side of the connection edge, and a centralized storage cabinet for gas cylinders is provided in the gas path and safety zone. The centralized storage cabinet integrates hydrogen cylinders and air cylinders. A combustible gas sensor and a gas audible and visual alarm are installed on the top of the centralized storage cabinet. The centralized storage cabinet is also equipped with a forced exhaust fan. The combustible gas sensor, the gas audible and visual alarm, and the forced exhaust fan are all electrically connected to the controller.

[0017] The gas pipeline and safety area are centrally equipped with a centralized storage cabinet for gas cylinders, which uniformly isolates and stores flammable cylinders such as hydrogen cylinders and air cylinders, realizing centralized control of hazardous sources and reducing the safety risks caused by gas cylinder leaks and collisions from the source. The combustible gas sensor, gas audible and visual alarm and forced exhaust fan are linked and uniformly controlled by the controller, which can monitor the concentration of combustible gas in the cabin in real time. In the event of a leak, it can immediately issue an audible and visual alarm signal and automatically start the exhaust fan to quickly reduce the concentration of combustible gas in the cabin and ensure the safety of the vehicle-mounted working environment.

[0018] Furthermore, the power distribution and energy storage area is located on one side of the connection edge. The power distribution and energy storage area is equipped with a power distribution control cabinet, a battery pack, a vehicle-mounted generator compartment, and a mains power interface. The vehicle-mounted generator compartment and the mains power interface are electrically connected to the battery pack and the power distribution control cabinet.

[0019] With a triple power supply mode, the equipment can be directly connected to the mains power supply when available, and can generate its own power through the vehicle-mounted generator when there is no mains power. The battery pack can store power and provide emergency power, ensuring continuous and stable power supply for the testing equipment in various field environments and improving the equipment's environmental adaptability.

[0020] Furthermore, the environmental protection zone is located on the upper part of the inner wall of the cabin, and the environmental protection zone is equipped with an air conditioner, a temperature and humidity sensor, and a top exhaust fan. The temperature and humidity sensor, the air conditioner, and the top exhaust fan are electrically connected to the controller.

[0021] The environmental protection equipment is integrated into the upper part of the inner wall of the container, without occupying the testing and operation space, making reasonable use of the three-dimensional space of the container and further improving the space utilization rate.

[0022] Furthermore, the storage area is located on the side wall near the upper part of the interior wall of the compartment, and includes multiple overhead cabinets. This fully utilizes the unused three-dimensional space of the compartment, without occupying space for testing operations and equipment placement, further improving the utilization rate of the limited space on the vehicle.

[0023] Furthermore, the integrated auxiliary functional structure includes site lighting installed on the outside of the box-type cabin, and electric support legs installed at the four corners of the mobile platform chassis.

[0024] The exterior of the van-type chassis is equipped with site lighting, providing ample illumination for on-site sampling and testing operations in special scenarios such as nighttime, underground power distribution rooms, and dimly lit outdoor environments. This solves the lighting challenges in special environments and enhances the equipment's adaptability to different scenarios. The mobile platform chassis is equipped with electrically operated support legs at its four corners. During testing operations, the support legs can be electrically lowered to stably fix the vehicle body to the ground, effectively preventing vehicle swaying or tilting from affecting the operational accuracy of the testing instruments and ensuring the accuracy of the test results.

[0025] Furthermore, the experimental cabinet is equipped with a clean water tank and a wastewater tank, and the experimental handwashing sink is equipped with a faucet and a water pipe. The faucet is connected to the clean water tank through the water pipe, and the experimental handwashing sink is connected to the wastewater tank through the water pipe.

[0026] The experimental cabinet integrates a clean water tank and a wastewater tank, which are connected to the handwashing sink for experiments via water pipes. This enables the independent supply of experimental water and the centralized collection of experimental wastewater, eliminating the need to rely on on-site water sources and sewage facilities, and enhancing the equipment's ability to operate independently on-site.

[0027] The beneficial effects of this utility model through the above technical solution are as follows:

[0028] This utility model utilizes multiple experimental cabinets to form a U-shaped operating area. Leveraging the integrated structure of the cabinets and tabletop, combined with square placement slots on the tabletop, it achieves standardized and organized placement of testing equipment, avoiding space waste caused by haphazard equipment placement and significantly improving the utilization rate of limited vehicle space. By dividing the compartment into functional areas such as a pneumatic and safety zone, and a power distribution and energy storage zone, and simultaneously setting a central control and operation area in the center of the U-shaped operating area, it achieves a zoned layout for testing, control, and auxiliary functions, making the work process clearer and the operator's workflow more rational. Pre-embedded pipes and wiring channels within the compartment and experimental cabinets prevent exposed, messy, and tangled pipelines, maintaining a clean operating environment and preventing pipeline damage from external impacts and vibrations, while also facilitating equipment disassembly and maintenance. The integrated external auxiliary functional structure complements the internal functional areas, making the entire experimental platform an integrated testing carrier adapted to the vehicle environment, providing comprehensive support for on-site testing operations.

Detailed Implementation

[0034] Example 1

[0035] As shown in Figures 1-4, a U-shaped test bench for a vehicle-mounted oil and chemical testing system includes a mobile platform chassis 1 and a box-type cabin 2 mounted on the mobile platform chassis 1. The box-type cabin 2 is equipped with multiple test cabinets 3, which are arranged along the two side walls and the rear of the box-type cabin 2 to form a U-shaped operating area. Each test cabinet 3 includes a cabinet body and a table surface. A placement slot 4 is provided on the table surface, and the placement slot 4 has a square structure.

[0036] The compartment 2 is also equipped with a gas passage and safety area, a power distribution and energy storage area, an environmental protection area and a storage area. The exterior of the compartment 2 is equipped with an integrated auxiliary function structure. The experimental cabinet 3, located in the center of the U-shaped operation area, has a central control and operation area.

[0037] Pipelines and wiring channels are pre-embedded inside the box-type cabin 2 and the experimental cabinet 3.

[0038] The U-shaped operating area includes a first long side, a second long side, and a connecting side. The placement slot 4 at the position of the first long side is arranged in sequence with a fully automatic insulating oil analysis gas chromatograph 5, a host computer, a printer, a tension tester, and an insulating oil acid value tester 6.

[0039] The placement slot 4 at the second long side position is arranged in sequence with a flash point tester, an insulating oil dielectric loss tester 7, a water-soluble acid value tester 8, an insulating oil withstand voltage tester 9, and a handwashing basin 10 for experiments.

[0040] A trace moisture tester 11 and a portable particle size analyzer are installed in the placement groove 4 at the connecting edge position.

[0041] The central control and operation area is equipped with a controller 12 and a power distribution control cabinet 13. The controller 12 is connected to a fully automatic insulating oil analysis gas chromatograph 5, a host computer, a printer, an insulating oil acid value tester 6, a tension tester, a flash point tester, an insulating oil dielectric loss tester 7, a water-soluble acid value tester 8, an insulating oil withstand voltage tester 9, a trace moisture tester 11, and a portable particle size analyzer.

[0042] The gas path and safety zone are located on one side of the connection edge. The gas path and safety zone are equipped with a gas cylinder centralized storage cabinet 14, which integrates hydrogen cylinders and air cylinders. A combustible gas sensor 15 and a gas audible and visual alarm are installed on the top of the gas cylinder centralized storage cabinet 14. The gas cylinder centralized storage cabinet 14 is also equipped with a forced exhaust fan 16. The combustible gas sensor 15, the gas audible and visual alarm, and the forced exhaust fan 16 are all electrically connected to the controller 12.

[0043] The power distribution and energy storage area is located on one side of the connection edge. The power distribution and energy storage area is equipped with a power distribution control cabinet 13, a battery pack 27, a vehicle-mounted generator compartment 17, and a mains power interface 18. The vehicle-mounted generator compartment 17 and the mains power interface 18 are electrically connected to the battery pack 27 and the power distribution control cabinet 13.

[0044] The environmental protection zone is located on the upper part of the inner wall of the compartment 2. The environmental protection zone is equipped with an air conditioner 19, a temperature and humidity sensor 20, and a top exhaust fan 22. The temperature and humidity sensor 20, the air conditioner 19, and the top exhaust fan 22 are electrically connected to the controller 12.

[0045] The storage area is located on the side wall near the upper part of the inner wall of the compartment 2, and includes multiple hanging cabinets 21.

[0046] The integrated auxiliary function structure includes site lighting 24 installed outside the box-type cabin 2, and electric support legs 23 installed at the four corners of the mobile platform chassis 1.

[0047] The experimental cabinet 3 is equipped with a clean water tank 25 and a wastewater tank 26. The experimental handwashing sink 10 is equipped with a faucet and a water pipe. The faucet is connected to the clean water tank 25 through the water pipe, and the experimental handwashing sink 10 is connected to the wastewater tank 26 through the water pipe.

[0048] During operation, the testing vehicle equipped with this U-shaped test bench is driven to the sampling site for insulating oil of power equipment. Depending on the available space, the vehicle is parked in a flat location that facilitates sampling. Then, the electric support legs 23 in the integrated auxiliary function structure are activated to extend the electric support legs 23 at the four corners of the mobile platform chassis 1 downwards and press them firmly against the ground, thus fixing the vehicle body horizontally and preventing the vehicle body from shaking during subsequent testing operations, which could affect the accuracy of the instrument. If the work site is in a dark environment such as at night or in an underground power distribution room, the site lighting 24 outside the box-type cabin 2 is turned on to provide sufficient lighting for on-site sampling and test bench operation.

[0049] Check if there is a mains power interface at the work site. If so, connect the mains power line to the mains power interface 18 of the test bench, and supply power to all equipment in the box 2 through the power distribution control cabinet 13, while charging the battery pack 27. If there is no mains power at the site, start the vehicle-mounted generator compartment 17, and the generator will provide power to the equipment. The power distribution control cabinet 13 will realize unified power control to ensure stable power supply to all equipment.

[0050] The controller 12 in the central control and operation area turns on the air conditioner 19 and the temperature and humidity sensor 20 in the environmental protection area. The temperature and humidity sensor 20 monitors the temperature and humidity data in the cabin 2 in real time and transmits it to the controller 12. The controller 12 automatically adjusts the operation of the air conditioner 19 according to the standard temperature and humidity requirements for insulating oil testing. At the same time, the top exhaust fan 22 can be turned on as needed to realize air circulation in the cabin and adjust the cabin environment to meet the testing requirements. After the temperature and humidity stabilize, the environmental preparation is completed.

[0051] Check the gas cylinder storage cabinet 14 in the gas circuit and safety area to confirm that the valves of the internal hydrogen cylinders and air cylinders are closed and the connections are sealed. Then turn on the power of the combustible gas sensor 15 and the gas audible and visual alarm to put them into working condition and ensure that the sensor, controller 12 and forced exhaust fan 16 are linked normally. At the same time, check whether the water tank 25 in the experimental cabinet 3 has enough water and whether the wastewater tank 26 is empty. Confirm that the faucet and water pipe of the experimental handwashing sink 10 are sealed and there is no leakage.

[0052] In the central control and operation area, via controller 12, all testing instruments in each of the U-shaped operation area's placement slots 4 are sequentially activated, including the fully automatic insulating oil gas chromatograph 5, insulating oil acid value tester 6, insulating oil dielectric loss tester 7, water-soluble acid value tester 8, insulating oil withstand voltage tester 9, and trace moisture tester 11. Simultaneously, the host computer and printer are turned on, and each instrument enters the self-test mode. The operator checks the self-test status of each instrument through the host computer. Once all instruments pass the self-test, the testing preparation work is completed.

[0053] During operation, insulating oil samples collected from power equipment are sent to the connecting edge of the U-shaped operating area on the experimental platform. This area serves as the sample pretreatment area. A portable particle size analyzer is used to perform preliminary particle size testing on the oil sample. At the same time, according to the sample requirements of each testing instrument, the oil sample is pretreated by dispensing, filtering, and other pretreatment operations. During the pretreatment process, the utensils can be cleaned through the experimental handwashing sink 10. The water in the handwashing sink 10 is supplied by the clean water tank 25, and the wastewater is discharged into the wastewater tank 26 through the water pipe to achieve centralized collection of sewage.

[0054] The operator stands in the control and operation area in the center of the U-shaped operation zone and performs a complete set of tests on the insulating oil sequentially along the first and second longest sides of the U-shaped operation zone using the shortest operating route. The specific operation is as follows:

[0055] First long-side detection: The pretreated oil sample is sent into the fully automatic insulating oil analysis gas chromatograph 5. After setting the detection parameters, the chromatographic analysis is started. The detection data is transmitted to the controller 12 in real time and displayed in the host computer. After the chromatographic detection is completed, the oil sample tension and acid value are detected by the tension tester and the insulating oil acid value tester 6 in sequence. All detection data are collected and summarized by the controller 12.

[0056] Second long-side testing: The oil sample is sent into the flash point tester, insulating oil dielectric loss tester 7, water-soluble acid value tester 8, and insulating oil withstand voltage tester 9 respectively. The flash point, dielectric loss, water-soluble acid value, and withstand voltage performance are tested in sequence according to the insulating oil testing standards. The operation and data reading of each instrument are completed uniformly in the central control and operation area, without the need for operators to repeatedly go back and forth.

[0057] Additional testing at the connection point: The oil sample is sent into the trace moisture analyzer 11 to complete the detection of trace moisture content in the oil sample, which, together with the previous particle size detection data, forms complete physicochemical index data of the oil sample.

[0058] After all the tests are completed, the operator reviews and organizes the test data stored in the controller 12 via the host computer. After confirming that the data is correct, the operator prints the insulating oil test report on-site through the printer connected to the controller 12, providing real-time data support for fault diagnosis and hidden danger investigation of power equipment.

[0059] During the detection process, if the combustible gas sensor 15 detects that the concentration of combustible gas in the compartment 2 exceeds the standard, it will immediately transmit a signal to the controller 12. The controller 12 will automatically trigger the gas audible and visual alarm to issue an alarm signal and start the forced exhaust fan 16 to exhaust the gas until the gas concentration in the compartment returns to a safe range. The operator will then check the gas circuit connection of the gas cylinder centralized storage cabinet 14 according to the alarm prompt, eliminate the potential for leakage, and continue the operation.

[0060] After testing, in the central control and operation area, use controller 12 to sequentially shut down all testing instruments, reset the operating parts and testing accessories of each instrument, and simultaneously turn off the printer and host computer to ensure that all instruments are in standby / shutdown mode. Turn off environmental protection equipment such as temperature and humidity sensor 20, air conditioner 19, and top exhaust fan 22, as well as safety equipment such as combustible gas sensor 15 and gas audible and visual alarm. If using mains power, first disconnect the line connection of mains interface 18. If using vehicle-mounted generator compartment 17 for power supply, turn off the generator and reset the oil and electrical circuits. Finally, cut off the main power supply through power distribution control cabinet 13 to ensure that there are no live devices in the compartment. Clean the experimental glassware and oil sample residues on each table in the U-shaped operation area. After cleaning the glassware again through the experimental handwashing sink 10, classify and store the glassware, testing consumables, and remaining oil samples into the hanging cabinet 21 on the upper part of the inner wall of the compartment 2, and close the cabinet door. Check the remaining water level in the clean water tank 25 and record the collection status of the wastewater tank 26 for subsequent water replenishment and wastewater cleaning. After confirming that all equipment and materials on the test bench have been stored, the electric support legs 23 are retracted upwards by the controller 12 until they are fully reset to the four corners of the mobile platform chassis 1. The site lighting 24 is then turned off, and the test vehicle is driven away from the work site to complete the on-site testing of the insulating oil.
