Description

Technical Field

[0001] This utility model relates to the field of high-voltage fuse mechanical performance testing technology, and in particular to a high-voltage fuse quality testing device. Background Technology

[0002] In power systems, high-voltage fuses are critical protective components, and their stability and reliability directly affect the safe operation of the entire power system. High-voltage fuses not only need to maintain stable electrical performance under normal operating conditions, but also need to maintain their structural integrity and functional effectiveness under repeated operation, accidental impacts, and vibrations during transportation or operation.

[0003] However, existing high-voltage fuse testing methods and technologies often have limitations, making it difficult to comprehensively and accurately evaluate fuse performance under various complex environments. Specifically, traditional testing methods may only focus on the electrical performance of the fuse under static conditions, neglecting its mechanical stability during repeated operation; or they may only assess the impact resistance of the casing through simple drop tests, lacking precise measurements of the specific stress and deformation during the impact; or when simulating vibration environments, they may fail to accurately reflect the complex vibration conditions that the fuse may encounter during transportation or operation, leading to discrepancies between the evaluation results and actual application conditions.

[0004] These problems mean that in practical applications, high-voltage fuses may fail to withstand the mechanical stress from repeated operation, physical damage from accidental impacts, or structural loosening and electrical connection failure under vibration, leading to power system faults or even more serious safety accidents. Therefore, developing a quality testing device that can comprehensively and accurately evaluate the performance of high-voltage fuses under various complex environments has become an urgent technical problem to be solved in the field of power system safety.

[0020] Unless otherwise defined, the technical or scientific terms used in this invention shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0021] Example 1 like Figures 1-2 As shown, this utility model discloses a high-voltage fuse quality testing device, which includes a testing platform 1. The testing platform 1 is equipped with a stability testing mechanism, a shell strength testing mechanism, and a vibration testing mechanism. The testing platform 1 serves as the basic platform of the entire testing device, supporting and fixing the other testing mechanisms to ensure the stability of the testing process.

[0022] An AC power supply 3 is provided at one end of the stability testing mechanism, and a shell strength testing mechanism is provided at the other end of the stability testing mechanism. A vibration testing mechanism is provided at one end of the shell strength testing mechanism, and a testing box 23 is provided at one end of the vibration testing mechanism.

[0023] The stability testing mechanism includes a fixed frame 4, a rotating disk 6 mounted above the fixed frame 4, a fixing hole 7 above the rotating disk 6 with contacts inside the fixing hole 7, a rotating frame 5 connected above the rotating disk 6, a robotic arm 12 mounted on the rotating frame 5, and a fixing disk 8 fixedly connected to the top of the rotating frame 5 with fixing contacts 9. The fixed frame 4 and the rotating disk 6 simulate the repeated switching action of a fuse in actual operation, with the contact and separation of the fuse achieved by the rotation of the rotating disk 6. The fixing hole 7 and the contacts are located on the rotating disk 6, forming an electrical connection with the contact disk on the rotating frame 5, used to test the electrical performance and mechanical stability of the fuse during repeated contact and separation.

[0024] The bottom of the fixed frame 4 is provided with a mounting bracket 2. The fixed frame 4 is fixedly connected to the testing table 1 through the mounting bracket 2. The bottom of the rotating disk 6 is provided with a motor. The motor is fixed to the bottom of the fixed frame 4, and the output shaft of the motor is connected to the rotating disk 6.

[0025] like Figure 3 As shown, one end of the robotic arm 12 is connected to the output shaft of the rotating gear 11. The rotating gear 11 is electrically connected to the rotating motor 10. The robotic arm 12 includes a rotating rod 14 and a fixed clamp 15. The fixed clamp 15 is located at the end of the rotating rod 14, and a displacement sensor 13 is installed on the rotating rod 14. A storage spring 17 is installed inside the fixed clamp 15, and a push block 18 is connected to the end of the storage spring 17. Rubber layers 16 are installed on the two clamping arms of the fixed clamp 15. The robotic arm 12 is used to grasp and place high-voltage fuses to realize an automated testing process. The rotating rod 14 has a rotation function to adjust the direction of the fuse; the fixed clamp 15 has a storage spring 17 and a push block 18 inside, which are used to push the fuse into the drop platform 19 in a specific step.

[0026] The casing strength testing mechanism includes a drop platform 19, which is a slope structure, and a pressure sensor 20 is installed on the drop platform 19. The slope structure design simulates the scenario when the fuse is accidentally dropped or impacted, and the pressure sensor 20 accurately measures the deformation and stress of the fuse casing when impacted.

[0027] The vibration detection mechanism includes a drive motor 21 and rotating rollers 22. The output shaft of the drive motor 21 is connected to the rotating rollers 22, and the distance between the rotating rollers 22 is smaller than the diameter of the high-voltage fuse. The drive motor 21 drives the rotating rollers 22 to rotate, simulating the vibration environment that the fuse may encounter during transportation or operation. The distance between the rotating rollers 22 is designed to be smaller than the diameter of the high-voltage fuse to ensure that the fuse can fully contact the rotating rollers 22 during vibration.

[0028] The detection box 23 is located at the bottom of the rotating roller 22 at the end of the vibration detection mechanism, and a conductive block 24 is installed inside the detection box 23. The positive and negative terminals of the AC power supply 3 are electrically connected to the contacts in the fixing hole 7 and the fixing contact 9, respectively. The positive and negative terminals of the AC power supply 3 are also electrically connected to the conductive blocks 24 at both ends inside the detection box 23, respectively.

[0029] The working process of the above device is as follows: The rotating rod 14 of the robotic arm 12 is adjusted to the appropriate position, and the fixing clamp 15 grasps the high-voltage fuse and places it in the fixing hole 7 of the rotating disk 6. The rotating disk 6 rotates under the drive of the motor, realizing the repeated contact and separation of the fuse. At the same time, the AC power supply 3 supplies power to test the electrical performance and mechanical stability.

[0030] After the stability test is completed, the rotating rod 14 of the robotic arm 12 rotates, placing the high-voltage fuse horizontally. The storage spring 17 stores power, and then the push block 18 pops out, causing the high-voltage fuse to slide out of the fixing clamp 15 and into the drop platform 19. The high-voltage fuse slides down the drop platform 19, simulating an accidental drop or impact scenario, and the pressure sensor 20 records the force data and deformation.

[0031] The high-voltage fuse, sliding down the drop platform 19, is caught by the rotating roller 22. The drive motor 21 starts, causing the rotating roller 22 to rotate, simulating the vibration environment during transportation or operation. The high-voltage fuse vibrates between the rotating rollers 22, simulating actual transportation or operating conditions. After vibration testing, the high-voltage fuse enters the test box 23, contacts the conductive block 24, and its electrical connection performance is tested. The system collects and analyzes all test data, evaluates the mechanical stability, shock resistance, and structural stability of the high-voltage fuse, and generates a test report.

[0032] Therefore, this utility model adopts the above-mentioned high-voltage fuse quality testing device, which integrates a stability testing mechanism, a shell strength testing mechanism, and a vibration testing mechanism. By simulating the actual working conditions of the fuse under repeated operation, accidental impact, and transportation / operation vibration environments, it uses a fixed disk and a rotating disk to test the electrical performance and mechanical stability, a drop platform to evaluate the shell's impact resistance, and a drive motor to drive the rotating roller to simulate the vibration environment. This comprehensively verifies the fuse's mechanical stability, impact resistance, and structural stability, effectively overcoming the technical limitations of existing testing methods in terms of comprehensiveness, authenticity, and reliability.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
