Abstract

The drawer mechanical interlocking mechanism for the low-voltage power distribution cabinet comprises a bottom plate, a cabinet body is welded to the center of the top of the bottom plate, vertical partition plates are welded to the top and the bottom of the inner side of the cabinet body, and transverse partition plates are welded to the other side walls of the vertical partition plates and the inner side walls of the cabinet body; the multiple sets of transverse partition plates are arranged at equal intervals, every two adjacent sets of transverse partition plates form a set of power distribution bin, mounting holes are formed in the two side walls of each power distribution bin, and first gears are rotationally mounted at the tops and the bottoms of the inner sides of the mounting holes. According to the drawer mechanical interlocking mechanism for the low-voltage power distribution cabinet, the drawer unit is fixed and limited through meshing of the first gear and the rack, the limiting stability of the drawer unit is ensured, the operation difficulty is reduced to a certain extent, and the problems that a traditional drawer mechanical interlocking mechanism is complex in structure and inconvenient to operate are solved. And the normal maintenance operation of the maintenance personnel is effectively ensured, and the practicability of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a drawer mechanical interlocking mechanism for low-voltage power distribution cabinets. Background technique [0002] In modern distribution network and engineering construction, withdrawable low-voltage distribution cabinets (hereinafter referred to as distribution cabinets) are widely used in power distribution systems in power plants, substations, factories and mines, and high-rise buildings. Power distribution cabinets play an important role as power conversion, distribution and control of power distribution, motor control and lighting distribution equipment. The drawer is provided with a mechanical interlocking mechanism to prevent the drawer from being opened with electricity. The mechanical interlocking mechanism controls the circuit in the power distribution cabinet to be disconnected when the drawer is pulled out, and the control circuit is connected ...
