Detailed Implementation

[0020] Example: Figure 1 and Figure 2As shown, it includes an insulation resistance tester 1, a display screen 2, a switch 4, and a knob 5. The display screen 2 is mounted on the front of the insulation resistance tester 1 by screws. A connection hole 3 is provided on the upper front side of the insulation resistance tester 1. The switch 4 is mounted on the right front side of the insulation resistance tester 1 by screws. The knob 5 is rotatably connected to the lower front side of the insulation resistance tester 1. The insulation resistance tester 1, the display screen 2, and the knob 5 are all electrically connected to the switch 4. The outer shell of the insulation resistance tester 1 is made of carbon fiber.

[0021] When using this device, first, connect one end of the test lead to the designated connection hole 3 on the device, and then connect the other end to the device under test, ensuring a stable and complete test circuit. This provides a reliable electrical connection foundation for subsequent measurements. Next, start the insulation resistance tester 1 via switch 4 and activate the display screen 2. This allows the data collected in real time by the insulation resistance tester 1 to be clearly and intuitively displayed on the display screen 2, facilitating timely observation and recording of relevant values ​​by the operator, thus improving testing efficiency. Then, according to the rated voltage and insulation class requirements of the device under test, rotate the adjustment knob 5 to select an appropriate voltage level, for example, gradually adjusting from 500V to 5000V to meet the insulation performance testing needs in different scenarios. Simultaneously, by controlling the start and stop of the high-voltage output, the device effectively avoids voltage fluctuations while ensuring measurement accuracy. The device mitigates the risk of equipment damage from overvoltage loading. The entire testing process not only ensures the accuracy and repeatability of measurement data but also significantly enhances operational safety and controllability, effectively avoiding measurement errors or electrical safety accidents caused by voltage incompatibility. Furthermore, the device's flexible voltage adjustment mechanism not only enhances its adaptability to various electrical equipment but also extends the service life of the tested equipment to a certain extent, preventing insulation breakdown or material aging caused by excessive voltage during testing. This achieves efficient, safe, and accurate insulation performance evaluation. Carbon fiber material possesses excellent insulation properties, effectively blocking leakage risks and ensuring operational safety. Its lightweight characteristics further enhance the device's portability and ease of use. After testing, the insulation resistance detector 1 automatically releases residual charge to prevent electric shock to operators.

[0022] like Figure 1 and Figure 2 As shown, it also includes a support plate 6, conductor posts 7 and a clamping frame 8. The support plate 6 is welded to the bottom of the insulation resistance tester 1, and conductor posts 7 are symmetrically welded to the left and right sides of the front of the support plate 6. The clamping frame 8 is welded to the right side of the insulation resistance tester 1.

[0023] like Figure 1 and Figure 2 As shown, it also includes a protective pad 9. The front of the clamping frame 8 is glued with the protective pad 9, which is made of rubber.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, it also includes a mounting plate 10, a clamping plate 11, a guide rail 12, and a positioning plate 13. The mounting plate 10 is installed on the back of the insulation resistance tester 1 by screws. The clamping plate 11 is welded to the back of the mounting plate 10. The guide rail 12 is clamped onto the clamping plate 11. The positioning plate 13 is welded to the back of the guide rail 12.

[0025] When inspecting higher equipment, the operator can first insert one end of the test line into the designated connection hole 3 of the device to ensure good contact. Then, the test line is wound orderly around the appropriate guide post 7 to avoid damage caused by tangling or pulling. Finally, the test end of the test line is clamped in the clamping frame 8. The rubber protective pad 9 effectively protects the test end of the test line to prevent damage caused by vibration or collision during transportation or climbing. Then, the device is firmly clamped to the guide rail 12 by the clamping plate 11, and the clamping plate 13 securely fixes the device to the operator's belt, making the device easy to carry and use on site, greatly improving the portability and ease of operation of the device, making the inspection work more efficient and safe. After completing the above preparations, the operator can carry the device safely to the high-altitude work area. After reaching the destination, the operator only needs to remove the other end of the test line from the clamping frame 8 to quickly start the inspection work, improving operational efficiency and safety, and ensuring the convenience of high-altitude operations and the reliability of equipment inspection.
