AI Technical Summary

Technical Problem

The existing high-voltage fuse brackets have a fixed height that cannot be adjusted, and the mounting holes are not easily compatible with the mounting holes of outdoor utility poles, crossarms, and electrical cabinets, resulting in inconvenient installation.

Method used

A bracket-type high-voltage fuse was designed. The screw is driven to rotate by the meshing of the worm gear and worm wheel. The height of the lifting column and the insulating base plate can be adjusted by the threaded connection. The position of the mounting hole can be adjusted by the telescopic groove and the limiting groove, so as to achieve flexible installation of the fuse.

Benefits of technology

It enables flexible adjustment of fuse height and adaptation of mounting holes, ensuring smooth connection of metal clamps to high-voltage lines and improving the practicality and flexibility of installation.
