A weak current security cabinet with long service life

Abstract

The invention discloses a weak current security cabinet with a long service life. The cabinet comprises a cabinet body and a bottom plate; the bottom of the cabinet body is fixedly connected with thetop of the bottom plate; the top of the cabinet body is fixedly connected with a top cover; a brake wheel is arranged at the top of the bottom plate; and the left side and the right side of one side of the top of the bottom plate are fixedly connected with the left side and the right side of one side of the bottom of the top cover through first connecting columns, and the left side and the right side of the other side of the top of the bottom plate are fixedly connected with the left side and the right side of the other side of the bottom of the top cover through second connecting columns. Theinvention relates to the technical field of power distribution cabinets. According to the invention, dust prevention can be conducted on the heat dissipation holes through cooperation of the second sleeves, the first connecting columns and the dustproof nets, so on one hand, the problem that the heat dissipation holes are blocked can be solved, on the other hand, when the power distribution cabinet moves, the connecting strips and the metal clamping strips can slide under the outer surface of the cabinet body, the gravity center of the whole cabinet body is increased, and then the safety of the high-weak current security cabinet is enhanced.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a weak current security cabinet with long service life. Background technique [0002] The power distribution cabinet is divided into the power distribution cabinet and the lighting distribution cabinet and the metering cabinet (box), which is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. The first-level power distribution equipment is ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a weak current security cabinet with a long service life, which solves the problem that the heat dissipation effect of the existing power distribution cabinet is relatively poor, and the heat dissipation holes are easily blocked by dust, which reduces the heat dissipation effect and causes power distribution The service life of the cabinet is shortened, and the core of the existing power distribution cabinet is unstable when moving, and it is prone to collisions, resulting in damage to the power distribution cabinet
