[0002] The intelligent plug-in test device for power automation equipment is a special device used to detect, evaluate and optimize the performance of intelligent plug-ins for power automation equipment. Through testing, it can ensure that the function, performance and reliability of the plug-in meet industry standards, avoid misoperation or refusal of protection due to plug-in failure, and ensure the safe and stable operation of the power grid. In addition, in complex application scenarios such as shipboard and airborne, electronic plug-ins are exposed to harsh environments such as high humidity, salt spray, and mold growth for a long time. Therefore, it is of great significance to simulate these environmental conditions during the test phase and conduct mold tests and salt spray tests.

[0003] At present, existing technologies are mostly limited to a single environment (shielding only or interference only), lack comparative data, and it is difficult to quantify the performance changes of the plug-in under electromagnetic interference, resulting in inaccurate tests on the adaptability and stability of the plug-in in complex electromagnetic environments, and it is difficult to discover in advance possible problems that may arise in the actual electromagnetic environment of the plug-in. In addition, the electromagnetic shielding lacks effective comprehensive wrapping and precise positioning measures, resulting in external electromagnetic interference that may affect the plug-in during the test, making the test environment not pure enough, and thus unable to ensure that the test results truly reflect the performance of the plug-in in the absence of electromagnetic interference, which interferes with the accurate evaluation of the plug-in performance.

[0015] Compared with the prior art, the advantages of the present invention are: The arrangement of the wire clamp and the wire trough in the present invention ensures the fixation and tidiness of the plug-in circuit, makes the internal circuit layout of the test device regular, avoids the disorderly entanglement of the circuit, is not only conducive to the installation, debugging and maintenance of the test device, but also reduces the risk of failure caused by circuit chaos, improves the reliability and stability of the test device, and the conductive foam can adapt to the size of the plug-in wire and fill the gap, improves the compatibility of the test device with different plug-ins, prevents the wire from loosening or shifting, and can also play a certain buffering and shock-absorbing role, protects the plug-in wire from damage, and extends the service life of the plug-in.

[0016] In the present invention, the cover plate and the wire clamp work together to form a complete wrapping of the plug-in, and the wire clamp groove at the bottom of the cover plate cooperates with the wire clamp shell to ensure that the cover plate is accurately docked when close to the installation groove, providing accurate protective positioning for the plug-in, and the cover plate wraps the plug-in to achieve electromagnetic shielding, creating a relatively pure electromagnetic environment for the plug-in, reducing the impact of external electromagnetic interference on the performance test of the plug-in, ensuring that the test results truly reflect the performance of the plug-in in the absence of electromagnetic interference, and using an electromagnetic interference generator to emit a corresponding degree of electromagnetic interference to the cabinet in an environment where the electromagnetic shielding is removed, and then testing the basic performance of the plug-in under interference and comparing it with the interference-free data can clearly understand the performance changes of the plug-in in the electromagnetic interference environment, evaluate the anti-interference ability of the plug-in, and provide an important basis for optimizing the design of the plug-in and improving its working performance in the actual electromagnetic environment.

[0017] In the present invention, the six-axis vibrator drives the cabinet to perform vibration test with the auxiliary support of the spring, simulating the vibration scenarios that the plug-in may encounter in actual work.

At the same time, the impact of cleaning on the performance of the plug-in can be monitored while the plug-in is in operation.

[0019] In the present invention, when a plug-in fails and subsequent tests cannot be continued, the power is cut off to the plug-in and the plug-in is isolated by the cover plate to ensure that the experiment continues safely. When the plug-in pushes the push door to rotate toward the inside of the cover plate, the push frame pushes the slip ring to slide along the slide groove and squeeze the spring, which plays a buffering role and avoids the plug-in from generating a large impact force when entering the cover plate and causing damage to the device or the plug-in itself. After the test is completed, the cover plate releases the cover on the plug-in, and at the same time, the elastic force of the spring causes the slip ring to slide and reset along the slide groove. The arc structure of the push frame can reset the push door that has been flipped into the inside of the cover plate to a closed state, ensuring that the device can quickly return to its initial state after the test is completed, preventing foreign matter from entering and affecting the experiment.

[0024] A plurality of mounting grooves 28 arranged in a rectangular array are provided on one side of the back plate 27 close to the cabinet door 3. A wire clamp 29 is provided below each mounting groove 28. The wire clamp 29 is composed of a shell 291 and a conductive foam 292.

The wires of each plug-in pass through the wire groove 26 and are electrically interconnected with the bus 14. The power control assembly provides power and test instructions for the plug-in. The arrangement of the wire clamp 29 and the wire groove 26 ensures that the plug-in circuit The fixation and tidiness make the internal circuit layout of the test device regular and avoid the disorderly entanglement of the circuits, which is not only conducive to the installation, debugging and maintenance of the test device, but also reduces the risk of failure caused by chaotic circuits and improves the reliability and stability of the test device. The conductive foam 292 can adapt to the size of the plug-in wires and fill the gaps, improve the compatibility of the test device with different plug-ins, prevent the wires from loosening or shifting, and at the same time play a certain buffering and shock-absorbing role, protect the plug-in wires from damage, and extend the service life of the plug-in. The outer wall of the cabinet 2 is fixedly installed with an environmental control assembly 24, and the side wall of the base 1 is fixedly installed with a display screen 13. The environmental control assembly 24 controls and detects environmental data such as temperature and humidity according to the test, and the tester observes and records the test data through the display screen 13.

[0025] The cabinet door 3 adopts a double-layer structure, consisting of an outer cabinet door 31 and an inner cabinet door 32. A cavity is formed between the inner cabinet door 32 and the outer cabinet door 31. The outer wall of the outer cabinet door 31 is fixedly installed with double-rod cylinders 33 distributed in a rectangular array. The telescopic end of each double-rod cylinder 33 is fixedly connected with a cover plate 35, and the cover plate 35 is located in the cavity. The multiple cover plates 35 correspond to the positions of the multiple installation grooves 28 respectively. The inner cabinet door 32 is provided with a guide through hole matching the movement trajectory of the cover plate 35. The double-rod cylinder 33 is started to push the cover plate 35 close to the corresponding installation groove 28 and cover the plug-in. The bottom of the cover plate 35 is provided with a wire clamp groove 3510, which is used for matching The cover plate 35 is connected to the housing 291 of the wire clamp 29 to ensure that the cover plate 35 is accurately docked with the wire clamp 29 when it is close to the installation groove 28, so that the cover plate 35 can stably cover the plug-in and provide accurate protection and positioning for the plug-in. The wire clamp 29 and the cover plate 35 work together to form a complete package for the plug-in. The cover plate 35 is rotatably connected to a push door 351, and the push door 351 is a double-door structure. The inner wall of the cover plate 35 is elastically connected to a slip ring 352 through a spring 2 356. The inner wall of the cover plate 35 is provided with a slide groove 355. The slip ring 352 is slidably connected to the slide groove 355. The slip ring 352 is rotatably connected to a pendulum 353 through a rotating shaft. A locking component is provided on the slip ring 352 to lock the The assembly includes a micro cylinder 359 fixedly mounted on the side wall of the slip ring 352, the telescopic end of the micro cylinder 359 is fixedly connected to a limit block 358, the limit block 358 is slidably connected to the inside of the slip ring 352, and the limit block 358 is located above the pendulum 353. The limit block 358 is pushed so that its bottom is against the top of the pendulum 353, so that the swing of the pendulum 353 can be limited. The state of the pendulum 353 can be flexibly controlled according to the test requirements. When it is necessary to simulate specific vibration conditions, the micro cylinder 359 drives the limit block 358 to move out of the top of the pendulum 353, and releases the pendulum 353 to allow it to swing and participate in the test. Under the action of the six-axis vibrator 11, The pendulum 353 is enabled to perform impact tests on the plug-in with different swing amplitudes. When the pendulum 353 does not need to move or is required to perform other test steps, the pendulum 353 is locked by the limit block 358 to ensure the accuracy and controllability of the test. A push frame 354 is fixedly installed on the side of the slip ring 352 close to the push door 351. The plug-in pushes the push door 351 to rotate toward the inside of the cover plate 35 and then enters the cover plate 35. When the push door 351 rotates, the push frame 354 pushes the slip ring 352 to slide along the slide groove 355 and squeezes the spring 2 356, which plays a buffering role and avoids a large impact force when the plug-in enters the cover plate 35, which may cause damage to the device or the plug-in itself.

[0026] The cover plate 35 wraps the plug-in to achieve electromagnetic shielding, creating a relatively pure electromagnetic environment for the plug-in, greatly reducing the impact of external electromagnetic interference on the plug-in performance test, ensuring that the test results truly reflect the performance of the plug-in in a state without electromagnetic interference, providing an accurate data basis for evaluating the electromagnetic compatibility of the plug-in, and helping to improve the stability of the plug-in in practical applications. The six-axis vibrator 11 drives the cabinet 2 to perform a vibration test with the auxiliary support of the spring 12 to simulate the vibration scenarios that the plug-in may encounter in actual work. Afterwards, the pendulum 353 is used to perform an impact test on the plug-in with different swing amplitudes in cooperation with the six-axis vibrator 11 to further simulate the impact conditions that the plug-in may face, and comprehensively evaluate the performance and reliability of the plug-in under complex working conditions. After the test, the double-rod cylinder 33 is reset to release the cover plate 35. In addition to covering the plug-in, the elastic force of the second spring 356 causes the slip ring 352 to move forward and reset along the slide groove 355. The head 357 of the push frame 354 is an arc-shaped structure, which can reset the push door 351 that is flipped into the cover plate 35 to a closed state, ensuring that the device can quickly return to its initial state after completing the test. An electromagnetic interference generator 21 is fixedly installed on the top of the cabinet 2. In an environment where the electromagnetic shielding is removed, the electromagnetic interference generator 21 is used to emit a corresponding degree of electromagnetic interference into the cabinet 2, and then the basic performance of the plug-in is tested under interference and compared with the previous interference-free data. This comparative test method can clearly understand the performance changes of the plug-in in the electromagnetic interference environment, evaluate the anti-interference ability of the plug-in, and provide an important basis for optimizing the design of the plug-in and improving its working performance in the actual electromagnetic environment.

[0027] The top of the cabinet 2 is fixedly connected with an atomizing nozzle 1 22 and an atomizing nozzle 2 23. The atomizing nozzle 1 22 sprays spore liquid into the interior of the cabinet 2. The environmental control assembly 24 performs environmental control at the same time to ensure the growth environment of the test mold. The tester tracks and records the plug-in data according to the display screen 13, simulating the harsh environment in which the plug-in may encounter mold erosion in actual use, which helps the tester to evaluate the tolerance and reliability of the plug-in in the mold environment, and discovers performance degradation, short circuit and other problems that may be caused by mold growth in advance, and provides data support for the application of the plug-in in outdoor, humid and other places where mold is easy to grow. The inner cabinet door 32 is provided on one side close to the back panel 27. Multiple groups of cleaning components are arranged. After the mold test is completed, the cleaning components clean the plug-in. The multiple groups of cleaning components correspond to the positions of multiple installation grooves 28 respectively. The cleaning components include a cleaning ring 36. The cleaning ring 36 is fixedly installed on the side of the inner cabinet door 32 close to the installation groove 28 through a cylinder 34. An annular air pipe 361 and a liquid pipe 362 are fixedly installed on the inner wall of the cleaning ring 36. A plurality of air jet nozzles are evenly arranged along the circumference on the inner side of the air pipe 361. A plurality of liquid spray nozzles are evenly arranged along the circumference on the inner side of the liquid pipe 362. The air pipe 361 is fixedly connected to an air inlet pipe 363. The liquid pipe 362 is fixedly connected to a liquid inlet pipe 364. Both the air inlet pipe 363 and the liquid inlet pipe 364 are hoses.

[0028] The liquid pipe 362 sprays a special charged cleaning liquid through a liquid spray nozzle to directly clean the plug-in, thereby avoiding the interface wear and poor contact problems caused by repeated plugging and unplugging. At the same time, the impact of cleaning on the performance of the plug-in can be monitored when the plug-in is in operation, ensuring that the cleaning process will not damage the normal operation of the plug-in. The cylinder 34 drives the cleaning ring 36 to reciprocate to achieve comprehensive cleaning of all parts of the plug-in. The lower end side wall of the cabinet 2 is fixedly connected to a drain pipe 25, and an inclined guide plate 210 is installed on the inner wall of the cabinet 2, and the lower end of the guide plate 210 faces the drain pipe 25. The dirty liquid generated by cleaning is collected by the guide plate 210 and discharged from the drain pipe 25 to reduce the stagnation of the dirty liquid. In order to reduce the risk of residual ozone and secondary contamination, after cleaning, pressurized ozone gas is sprayed through the air pipe 361 to disinfect the plug-in. Ozone can effectively kill residual mold spores and other microorganisms due to its strong oxidizing property, further ensuring the cleanliness and hygiene of the plug-in, preventing mold from growing again, and extending the service life of the plug-in. After disinfection, the environmental control assembly 24 automatically starts the strong exhaust mode to quickly remove residual ozone and ensure that the ozone concentration drops below the safety threshold to protect the health of operators. At the same time, the system maintains a dry environment in the cabinet, effectively preventing oxidation of plug-in contacts or degradation of insulation performance, providing stable environmental conditions for subsequent tests, and ensuring continuous and reliable test results.

[0029] After completing the cleaning and disinfection process, the atomizing nozzle 23 sprays salt spray solution to simulate the corrosion effect of the coastal high salt spray environment on the plug-in. The salt contained in the salt spray is corrosive and can corrode the metal parts, circuit boards, etc. of the plug-in, affecting its electrical and mechanical properties. By simulating this environment, the corrosion resistance of the plug-in in such special environments can be effectively evaluated, potential corrosion hazards can be discovered in advance, and the plug-in can be ensured to be able to operate stably in actual use, and its reliability in complex environments can be improved. Combined with the previous vibration, impact, electromagnetic shielding, electromagnetic interference, mold and other tests, the salt spray test further enriches the test device's performance inspection dimensions for the plug-in in different harsh environments. This comprehensive test system can more realistically reflect the various challenges that the plug-in may face in actual applications, making the test results more comprehensive and representative, and providing more comprehensive data support for the optimized design and quality improvement of the plug-in.

[0030] When the present invention is in use, the tester installs the plug-in into the installation slot 28 and then closes the cabinet door 3. The environmental control assembly 24 controls and detects environmental data such as temperature and humidity according to the test. The tester observes and records the test data through the display screen 13. The power control assembly provides power and test instructions to the plug-in. When the plug-in fails and subsequent tests cannot be continued, the power is cut off to the plug-in and the plug-in is isolated by the cover plate 35 to ensure that the experiment continues safely. The lines of each plug-in are merged into the bus 14 from the wire trough 26 and connected to the power control assembly in the base 1. The fixation of each plug-in line is ensured by the wire clamp 29.

[0031] The double-rod cylinder 33 drives the cover plate 35 to extend, and the cover plate 35 presses against the back plate 27 and covers the plug-in. The wire clamp groove 3510 and the shell 291 are closely matched to ensure electromagnetic shielding while preventing the cover plate 35 from crushing the line. As the plug-in enters the cover plate 35, the top of the plug-in pushes the push door 351 to turn inward, and the inward-turned push door 351 pushes the push frame 354 and the slip ring 352 connected thereto to move inward and squeeze the spring 2 356. The pendulum 353 adapts to the size of the plug-in to reach a suitable position. The plug-in is electromagnetically shielded by the back plate 27, the wire clamp 29 and the cover plate 35. In the electromagnetic shielding environment, each plug-in is powered on for performance testing to test the accuracy, reaction speed, whether the instructions are executed smoothly and other basic performance of the plug-in. Then the six-axis vibrator 11 is on the spring With the auxiliary support of one 12, the cabinet 2 is driven to perform a vibration test to monitor the use of the plug-in under different vibration environments. After the vibration test is completed, the micro cylinder 359 retracts to drive the limit block 358 to move out of the top of the pendulum 353, and the limit on the pendulum 353 is released, so that the pendulum 353 can swing freely. With the cooperation of the six-axis vibrator 11, the pendulum 353 performs an impact test on the plug-in with different swing amplitudes. After the impact test is completed, the micro cylinder 359 extends out to insert the limit block 358 into the top of the pendulum 353, and the double-rod cylinder 33 drives the cover plate 35 to reset, and the cover on the plug-in is released. Under the elastic force of the spring two 356, the sliding ring 352 moves forward along the slide groove 355 to reset, and the head 357 of the push frame 354 pushes the push door 351 to reset to a closed state.

[0032] In the environment of removing electromagnetic shielding, the electromagnetic interference generator 21 sends a corresponding degree of electromagnetic interference signal to the cabinet 2, tests the basic performance of the plug-in under interference and compares it with the previous data without interference, then the atomizing nozzle 22 sprays spore liquid in the cabinet, and the environmental control assembly 24 performs environmental control to ensure the growth environment of the mold used for testing. The tester tracks and records the plug-in data according to the display screen 13. After the mold test is completed, the liquid pipe 362 sprays the special charged cleaning liquid outward through the liquid spray nozzle under the supply of the liquid inlet pipe 364, and the cylinder 34 is continuously extended and retracted to clean the ring 3. 6 reciprocating motion to clean the plug-in, then the liquid pipe 362 stops working, and the air pipe 361 sprays pressurized ozone to disinfect the plug-in under the air supply of the air inlet pipe 363. The environmental control assembly 24 strengthens the exhaust to remove ozone and ensure the dryness of the cabinet 2. During this period, the dirty liquid falls on the guide plate 210 and is finally discharged from the drain pipe 25. After the cleaning and disinfection is completed, the atomizing nozzle 23 sprays salt mist, and the tester tracks and records the data. After the test is completed, the plug-in is cleaned again. After the tester has sorted out the data, the cabinet door 3 is opened, and the plug-in is removed and then the next batch of plug-ins are installed and tested.
