AI Technical Summary

Technical Problem

In existing low-voltage cabinets, primary and secondary wiring harnesses and other components are concentrated at the back of the cabinet, resulting in poor heat dissipation and inconvenience for customer wiring and maintenance. This problem is particularly serious when the cabinet depth is ≤600mm due to limited space.

Method used

The low-voltage cabinet is divided into a drawer compartment, a secondary cable compartment, a cable inlet/outlet compartment, and a busbar compartment. A terminal block that can slide back and forth is installed in the secondary cable compartment. The terminal side wire harness is fixed by a guide rail mechanism, guide members, and sliding members to form a U-shaped structure, thereby realizing the separation of the primary and secondary systems. A push-pull drawer unit is set in the drawer compartment.

Benefits of technology

It achieves separation of primary and secondary systems, improves heat dissipation and safety reliability, and enhances the convenience of operation and maintenance. It is suitable for low-voltage power distribution systems in power plants, substations, industrial and mining enterprises, and has significant advantages, especially in cabinets with limited depth.

Abstract

The utility model relates to a drawing type wiring low-voltage cabinet, which comprises a cabinet body divided into a drawer chamber, a secondary cable chamber, a cable incoming and outgoing line chamber and a bus chamber, the secondary cable chamber is arranged on the right side of the drawer chamber, and the cable incoming and outgoing line chamber is arranged on the rear side of the drawer chamber and the secondary cable chamber. The bus chamber is arranged on the upper sides of the drawer chamber, the secondary cable chamber and the cable inlet and outlet chamber, a terminal strip capable of sliding back and forth is installed in the secondary cable chamber through a guide rail mechanism, the guide rail mechanism comprises guide pieces fixed on the cabinet body at intervals up and down, the guide pieces are provided with sliding pieces matched with the guide pieces, and the terminal strip is fixed at the front ends of the sliding pieces. A terminal side wire harness connected with the terminal strip is correspondingly fixed on the guide piece and the sliding piece through two fixing points, the terminal side wire harness between the two fixing points forms a U shape, and the length of the terminal side wire harness between the two fixing points is greater than or equal to the maximum sliding distance of the sliding piece relative to the guide piece. The LED lamp has the advantages of simple structure, convenience in maintenance and good heat dissipation effect.
