AI Technical Summary

⚠Technical Problem

The existing high and low voltage distribution cabinets have a one-piece structure, which results in a long manufacturing cycle, making it difficult to meet the needs of large-scale production and rapid delivery, and lacking effective sealing and protection performance.

⚗Method used

The cabinet adopts a modular splicing structure. By combining splicing units, insert rods and seals, cabinets of different heights can be formed. The sealing performance is improved by using beveled sealing and seals, and the insert rods and locking nuts are used to lock and fix the cabinet.

🎯Benefits of technology

It shortens the manufacturing cycle, improves production efficiency, meets the needs of large-scale production and rapid delivery, and enhances the sealing and protection performance of the cabinet.

Abstract

This utility model discloses a modularly assembled high and low voltage switchgear cabinet structure, in which several sets of splicing units are stacked vertically to form a spliced ​​state. Each splicing unit includes a first frame, a second frame, and a beam connecting the first and second frames. The top of the first frame has a first inclined surface extending circumferentially; the bottom of the second frame has a second inclined surface extending circumferentially. In the spliced ​​state, the first inclined surface on the first unit and the second inclined surface on the second unit in adjacent layers are mutually abutted and sealed. Inserting rods are inserted vertically into each set of splicing units. A limiting block is provided on the first end of the inserting rod outside the splicing unit; a locking nut is threadedly connected to the second end of the inserting rod outside the splicing unit. This utility model, through modular splicing, can form cabinet structures of different heights, thereby shortening the manufacturing cycle, saving time and labor, and effectively meeting the needs of large-scale production and rapid delivery of high and low voltage switchgear.
