AI Technical Summary

Technical Problem

In the existing technology, the connection and fixing of transformer tap leads requires manual operation, which is labor-intensive, inefficient, and of unstable quality, and is prone to failure.

Method used

A tap changer lead pressing fixture was designed, including a base plate, a telescopic element, a fixed mold, and a moving mold. The telescopic element drives the linear displacement of the moving mold and the fixed mold. The protrusions and grooves are used to achieve a tight connection between the tap changer and the lead. The push force is buffered by a reset spring to improve the connection quality and efficiency.

Benefits of technology

It achieves stable connection of tap leads, reduces labor intensity, improves production efficiency, and avoids quality problems and malfunctions caused by manual operation.
