AI Technical Summary
Existing test equipment for fuse-type disconnect switches has a complex structure and poor adaptability, making it difficult to meet the composite testing requirements of various models and specifications, resulting in low testing efficiency and insufficient accuracy of results.
The system employs X-axis and Y-axis guide rails combined with a multi-link transmission assembly to enable flexible movement of the linkage seat in the X and Y directions. The action angle is adjusted through the multi-link transmission assembly, and the operating state under different working angles is simulated by combining a rotary drive plate and a positioning shaft structure. A power drive assembly and coupling are added to ensure transmission accuracy.
It enables rapid and accurate positioning and adjustment of fuse-type disconnect switches of different specifications and models, enhances the adaptability and versatility of the device, provides more comprehensive performance testing, and improves testing efficiency and accuracy.
