Description

Technical Field

[0001] This utility model relates to the technical field of surge arrester vibration testing devices, and more specifically, to a surge arrester testing bracket and vibration testing device. Background Technology

[0002] In modern society, power facilities, especially transmission lines, are ubiquitous in urban and rural areas, forming the lifeline of cities. Their health directly affects the reliable supply of electricity. However, the vulnerability of transmission lines cannot be ignored, especially when faced with natural disasters such as lightning strikes, where their stability and safety are severely tested. Surge arresters, as guardians of power facilities, are widely deployed on overhead lines, particularly at towers susceptible to lightning strikes, significantly improving the lightning protection performance of the lines and ensuring the safe and efficient transmission of electricity.

[0003] Under the harsh conditions of the outdoor environment, surge arresters are constantly subjected to wind force or tower vibrations, which can cause minute or even invisible cracks in their structure. This not only reduces the service life of the surge arrester but also threatens the operational safety of power lines. Therefore, vibration testing of surge arresters is necessary to evaluate their structural strength and stability, especially for newly designed surge arresters, which has become an indispensable part of product development and quality control. However, existing vibration testing equipment lacks the function of adjusting the installation angle of the surge arrester, and cannot simulate the vibration conditions of the surge arrester at the actual installation angle. As a result, the test results cannot accurately reflect the performance of the surge arrester under actual operating conditions, thus affecting the accuracy of the test. Utility Model Content

[0004] The main purpose of this utility model is to provide a surge arrester test bracket and vibration test device, which can solve the problem that the existing surge arrester test bracket and vibration test device lack the function of adjusting the installation angle of the surge arrester, resulting in the test results not being able to truly reflect the performance of the surge arrester at the actual installation angle and the test accuracy being poor.

[0005] To achieve the above objectives, according to one aspect of the present invention, a surge arrester vibration testing device is provided, comprising a base and a support portion.

[0012] Furthermore, an angle sensor is provided on the second support, which can monitor the tilt angle of the second support relative to the horizontal plane.

[0013] Furthermore, the second support is provided with mounting holes, and multiple mounting holes are arranged at intervals.

[0014] According to another aspect of the present invention, a vibration testing device is also provided, including the above-mentioned surge arrester testing bracket.

[0015] Furthermore, the vibration testing device also includes a vibration table, and the surge arrester test bracket is detachably connected to the vibration table. The vibration table can drive the surge arrester test bracket to vibrate.

[0016] Applying the technical solution of this utility model, the base is the fundamental component of the entire test bracket. Its main function is to provide stable support for the support section and the surge arrester on it, ensuring that it can withstand the weight of the surge arrester and the entire device during testing.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1 to 4 As shown, this utility model provides a surge arrester test bracket, which includes a base 1 and a support part 2. The support part 2 includes a first support part 21 and a second support part 22. The first support part 21 is disposed on the base 1, and the second support part 22 is rotatably connected to the first support part 21. The second support part 22 can support and fix the surge arrester. The surge arrester test bracket also includes an angle adjustment component, which can drive the second support part 22 to rotate relative to the first support part 21 to adjust the tilt angle of the second support part 22 relative to the horizontal plane.

[0026] In the above technical solution, the base 1 is the fundamental component of the entire test bracket. Its main function is to provide stable support for the support part 2 and the surge arrester on it, ensuring that it can withstand the weight of the surge arrester and the entire device during testing. Simultaneously, it connects the support part 2 and the surge arrester on it to the vibration table, enabling the vibration generated by the vibration table to be effectively transmitted to the surge arrester. The first support part 21 supports the second support part 22 and the surge arrester on it, and the second support part 22 provides the mounting foundation for the surge arrester. The second support part 22 is rotatably connected to the first support part 21, allowing the test bracket to adjust the tilt angle of the second support part 22 relative to the horizontal plane as needed, thereby achieving the effect of testing the surge arrester at different angles. The angle adjustment component typically includes a telescopic rod, a screw, or a lifting device, thereby driving the second support part 22 to rotate relative to the first support part 21.

[0027] By cooperating with the angle adjustment component through the rotatable second support 22, the test bracket can adjust the tilt angle of the second support 22 and the surge arrester on it as needed, simulating the actual installation angle of the surge arrester. This yields more realistic test data, truly reflecting the performance of the surge arrester under actual operating conditions and significantly improving test accuracy. Furthermore, the more realistic test data can guide and optimize the surge arrester design process, further enhancing the safety and reliability of the surge arrester in actual use.

[0028] In one embodiment of the present invention, the angle adjustment component includes an adjustment part 3, which is disposed at the first end of the first support part 21 and connected to the first end of the second support part 22. The second end of the first support part 21 is hinged to the second end of the second support part 22. The adjustment part 3 can adjust the height of the second end of the second support part 22 to adjust the tilt angle of the second support part 22 relative to the horizontal plane.

[0029] In the above technical solution, the main function of the adjusting part 3 is to change the tilt angle of the second support part 22 relative to the horizontal plane by adjusting the height of the second end of the second support part 22. This design allows users to precisely control the test angle of the surge arrester as needed, ensuring that the test conditions are as consistent as possible with the actual application scenario, thereby obtaining test results that are closer to reality. The angle adjustment operation of the adjusting part 3 can be achieved by various mechanical or electronic means, such as using a screw, a motor-driven linear actuator, etc., to change the height of the second end of the second support part 22. The first support part 21 and the second support part 22 are hinged together. When the adjusting part 3 changes the height of the second end of the second support part 22, the second support part 22 rotates around the hinge position, thereby realizing the adjustment of the tilt angle of the second support part 22 relative to the horizontal plane.

[0030] In one embodiment of the present invention, the first support portion 21 includes a first support segment 212, a second support segment 213, and a third support segment 214. The first support segment 212 is connected to the base 1, the first end of the first support segment 212 is connected to the second support segment 213, the adjustment portion 3 is disposed on the second support segment 213, the second end of the first support segment 212 is connected to the third support segment 214, the second support portion 22 is hinged to the third support segment 214, and the second support segment 213 and the third support segment 214 gradually extend upward in a direction away from the first support segment 212.

[0031] In the above technical solution, the first support section 212 is directly connected to the base 1, responsible for transferring the weight of the entire support structure and the load of the surge arrester to the base, thereby ensuring the stability of the test device during vibration. The second support section 213 is mainly used for installing and supporting the adjustment part 3. The third support section 214 is hinged to the second support part 22, providing the second support part 22 with a fulcrum and a center of relative rotation. The second support section 213 and the third support section 214 gradually extend upwards in a direction away from the first support section 212. This structural layout allows the adjustment part 3 to effectively control the tilt angle of the second support part 22, and also ensures that during vibration testing, the vibration generated by the vibration table can be smoothly transmitted to the surge arrester through the support part 2, reducing the stress concentration phenomenon caused by the abrupt change in the support structure during vibration transmission, thereby extending the service life of the test support.

[0032] In one embodiment of the present invention, the adjusting part 3 includes an adjusting screw 31, a first mounting part 211 is rotatably provided at the second end of the first support part 21, the adjusting screw 31 passes through the first mounting part 211 and is threadedly connected to the first mounting part 211, a second mounting part 221 is provided on the second support part 22, the second mounting part 221 is hinged to the second support part 22, and the adjusting screw 31 is rotatably connected to the second mounting part 221.

[0033] In the above technical solution, the first mounting part 211 is located at the second end of the first support part 21, and its function is to support the adjusting screw 31. The adjusting screw 31 is threadedly connected to the first mounting part 211. By rotating the adjusting screw 31, the length of the adjusting screw 31 extending or retracting from the first mounting part 211 can be precisely controlled, thereby adjusting the height of the second end of the second support part 22, and thus adjusting the tilt angle of the second support part 22. The advantages of the screw are its simple structure, convenient operation, and high-precision adjustment capability, which greatly improves the flexibility and accuracy of the test angle adjustment. During the process of adjusting the tilt angle of the second support 22 by rotating the adjusting screw 31, the angle of the adjusting screw 31 itself will also change. Therefore, the first mounting part 211 is rotatably connected to the first support 21, and the second mounting part 221 is hinged to the second support 22, thereby providing the adjusting screw 31 with greater angular freedom. This avoids the adjusting screw 31 being limited by the angle of the first mounting part 211 and the second mounting part 221 when adjusting the tilt angle of the second support 22, which would prevent the angle from being adjusted normally or the angle adjustment from being inaccurate.

[0034] In one embodiment of this utility model, a limiting part 5 is also provided on the adjusting screw 31, and the limiting part 5 can lock the adjusting screw 31.

[0035] In the above technical solution, the limiting part 5 usually includes components such as anti-loosening nuts or locking washers. Its main function is to prevent the adjusting screw 31 from loosening or shifting during the test, ensuring that the surge arrester can accurately maintain the set tilt angle during the test, thereby improving the accuracy and reliability of the test results.

[0036] In one embodiment of the present invention, which is not shown in the figures, the angle adjustment component further includes a driving device. The driving device is driven to the adjustment part 3. The driving device can drive the adjustment part 3 to adjust the height of the second end of the second support part 22 to adjust the tilt angle of the second support part 22 relative to the horizontal plane.

[0037] In the above technical solution, the introduction of a drive device enables the surge arrester vibration testing device to automate angle adjustment. This is typically achieved through electric, hydraulic, or pneumatic methods. The operator can set the test angle via a control panel or computer interface, and the drive device will automatically adjust the adjustment unit 3, thereby changing the tilt angle of the second support unit 22. This automated adjustment not only reduces the complexity of manual operation but also avoids human error, improving the accuracy and consistency of the test. Electric, hydraulic, or pneumatic drive devices typically have high control precision and can achieve minute angle adjustments. Manual angle adjustment consumes a significant amount of time, especially when multiple angle tests are required to comprehensively evaluate the surge arrester's performance. The drive device, however, can drive the adjustment unit 3 to quickly and continuously adjust the angle, greatly improving the efficiency of vibration testing. This allows testers to complete multi-angle vibration tests in a short time, accelerating the research and development and verification process of surge arresters.

[0038] In one embodiment of this utility model, a vibration sensor 6 is also provided between the base 1 and the support, and the vibration sensor 6 can acquire vibration data.

[0039] In the above technical solution, vibration sensor 6 is used to acquire vibration data transmitted to the surge arrester by the vibration table, providing a data foundation for subsequent data analysis and surge arrester performance evaluation. By analyzing the changes in vibration frequency, amplitude, and vibration mode, the stability and strength of the surge arrester under different angles and vibration conditions can be evaluated, providing a scientific basis for surge arrester design optimization, material selection, and production quality control.

[0040] In one embodiment of the present invention, an angle sensor is provided on the second support portion 22, and the angle sensor can monitor the tilt angle of the second support portion 22 relative to the horizontal plane.

[0041] In the above technical solution, the angle sensor can monitor the tilt angle of the second support 22 relative to the horizontal plane in real time, which is crucial for ensuring the consistency and accuracy of test conditions. By acquiring angle data in real time, the test conditions of the surge arrester under different tilt states can be precisely controlled and verified, avoiding errors that may be introduced by manual visual inspection or measurement. In the automated testing system, the angle sensor can be linked with components such as the vibration table and adjusting screw to automatically calibrate and provide feedback on the adjustment results according to the set test angle. This not only simplifies the preparation work before testing but also ensures the accurate setting of the test angle for each test, improving testing efficiency and data quality.

[0042] In one embodiment of the present invention, the second support portion 22 is provided with mounting holes 222, and a plurality of mounting holes 222 are arranged at intervals.

[0043] In the above technical solution, the mounting hole 222 provides a reliable installation interface for the surge arrester. Multiple spaced mounting holes 222 can accommodate the installation requirements of surge arresters of different sizes and shapes. By selecting different mounting holes, testers can adjust the installation position of the surge arrester on the support according to the specific specifications of the arrester under test or the test requirements, enhancing the versatility and adaptability of the testing device.

[0044] According to another aspect of the present invention, a vibration testing device is also provided, including the surge arrester testing bracket of the above embodiment.

[0045] In the above technical solution, the integration of the surge arrester test bracket and vibration testing device provides greater flexibility in experimental design. Users can easily adjust the installation angle and position of the surge arrester according to different testing objectives, simulating the actual installation angle of the surge arrester. They can collect and analyze the surge arrester's response data under various vibration conditions, including vibration frequency, amplitude, mode, and the impact of the surge arrester's tilt angle on its performance. This yields more realistic test data, truly reflecting the surge arrester's performance under actual operating conditions and significantly improving test accuracy. Using this test data to guide and optimize the surge arrester design process can further improve the safety and reliability of the surge arrester in actual use.

[0046] In one embodiment of this utility model, the vibration testing device further includes a vibration table, and the surge arrester test bracket is detachably connected to the vibration table. The vibration table can drive the surge arrester test bracket to vibrate.

[0047] In the above technical solution, a vibration table is used to generate vibration, which is then transmitted to the surge arrester via a surge arrester test bracket. By setting up a surge arrester test bracket with an adjustable test angle, when simulating different installation angles of the surge arrester, the user only needs to operate the angle adjustment component to quickly adjust the surge arrester test angle, without the need for additional tooling adjustments or cumbersome preparation work. This significantly improves the speed of the test preparation stage, thereby increasing the efficiency of the entire test process.

[0048] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The base 1 is the basic component of the entire test bracket. Its main function is to provide stable support for the support part 2 and the surge arrester on it, ensuring that it can bear the weight of the surge arrester and the entire device during the test. At the same time, it connects the support part 2 and the surge arrester on it to the vibration table, so that the vibration generated by the vibration table can be effectively transmitted to the surge arrester. The first support part 21 is used to support the second support part 22 and the surge arrester on it. The second support part 22 is used to provide the installation foundation for the surge arrester. The second support part 22 is rotatably connected to the first support part 21, so that the test bracket can adjust the tilt angle of the second support part 22 relative to the horizontal plane as needed, thereby achieving the effect of testing the surge arrester at different angles. The angle adjustment component usually includes a telescopic rod, a screw, or a lifting device, etc., thereby driving the second support part 22 to rotate relative to the first support part 21.

[0049] By cooperating with the angle adjustment component through the rotatable second support 22, the test bracket can adjust the tilt angle of the second support 22 and the surge arrester on it as needed, simulating the actual installation angle of the surge arrester. This yields more realistic test data, truly reflecting the performance of the surge arrester under actual operating conditions and significantly improving test accuracy. Furthermore, the more realistic test data can guide and optimize the surge arrester design process, further enhancing the safety and reliability of the surge arrester in actual use.
