AI Technical Summary

Technical Problem

The installation of electrical components inside existing low-voltage switchgear is inconvenient, especially in confined spaces where installation requires bending over or crawling into the cabinet, leading to operational difficulties.

Method used

A low-voltage switchgear with fire protection was designed, which adopts a sliding connection structure of uprights and crossbars. The crossbars and uprights are conveniently installed and disassembled through first and second fixing components. The fire protection is achieved by combining temperature sensors and an alarm system.

Benefits of technology

It simplifies the installation and disassembly process of electrical components, reduces the operational difficulty for staff, and provides timely alarms through temperature sensors, thereby reducing the risk of fire and achieving more efficient fire protection.

Abstract

The utility model relates to the field of switch cabinet equipment, and discloses a low-voltage switch cabinet with fireproof protection. The cabinet comprises a shell and a cabinet door hinged to the shell, mounting plates, a stand column connected to the mounting plates in a sliding mode and a transverse rod used for being fixed to the stand column are fixedly arranged in the shell, mounting grooves are formed in the mounting plates, the mounting grooves are formed in the length directions of the mounting plates, and the transverse rod is fixed to the stand column. The stand column is slidably connected into a mounting groove in the mounting plate, a first fixing assembly is arranged on the stand column, a second fixing assembly is arranged on the cross rod, the first fixing assembly is used for fixing the stand column to the mounting plate, and the second fixing assembly is used for fixing the cross rod to the stand column. A first sliding groove used for containing the transverse rod is formed in the side face of the mounting plate, a second sliding groove used for being communicated with the first sliding groove is formed in the stand column, and the device has the effect that components can be conveniently mounted in the shell.
