AI Technical Summary

Technical Problem

After a long period of use, the tripping structure of the existing adjustable air switch is affected by the weakening of magnetic force, and the length of the fixed decoupling lever does not adapt to the voltage and current fluctuations of different circuits.

Method used

By setting a first linear roller, a coil, a first excitation block, a second linear roller and a second excitation block in the air switch, the magnetic linkage between the coil and the excitation block is used to enhance magnetic stability; at the same time, the limit block, worm gear, rectangular lifting column, thread groove and worm are adopted to adjust the distance between the hoist and the chain.

Benefits of technology

It effectively improves the life of the air switch, ensures magnetic stability, and improves the ability to adapt to different circuits, enhancing the adaptability of the air switch.
