Description

Technical Field

[0001] This utility model relates to the field of support insulator technology, and in particular to a novel support insulator anti-compression device. Background Technology

[0002] Due to varying working environment requirements, post-type insulators necessitate a compressive strength test. This test primarily verifies insulation strength, ensuring equipment reliability under extreme conditions, preventing power outages due to insulation defects, guaranteeing power supply stability, and identifying low-value or zero-value insulators (insulators with breakdown voltages of zero or near zero). This prevents flashovers in polluted environments or under overvoltage conditions, reducing the risk of equipment damage. Therefore, routine compressive strength tests are required for post-type insulators after production. This test improves factory acceptance efficiency, ensures the rejection of substandard products, and enhances verification efficiency. Utility Model Content

Upper guide wheels 2 are provided on both sides of the top of the movable iron box 4 and the support plate 7 via guide wheel fixing plates 3. The guide wheel fixing plates 3 are fixed to the top of the movable iron box 4 and the support plate 7. A pressure-resistant plate 6 is fitted onto two parallel and spaced threaded rods 5. One end of each threaded rod 5 is threadedly connected to the movable iron box 4, and the other end of each threaded rod 5 passes through the support plate 7 and is connected to a nut. The two support plates 7 are connected to the tension testing machine head 11 via a connecting rod 1 8 and a connecting rod 2 10. One end of the connecting rod 1 8 passes through the middle of the support plate 7 and is secured with a nut, while the other end is threadedly connected to one end of the connecting rod 2 10. The other end of the connecting rod 2 10 is fixedly connected to the tension testing machine head 11.

[0014] The movable iron box 4, with its upper guide wheel 2 and lower guide wheel 9, can be adjusted and moved according to the product length.
