Electric power cabinet

Abstract

The invention discloses an electric power cabinet which comprises an electric power cabinet body composed of a cabinet body, a water collection box, an exhaust fan, an impurity prevention mechanism and a sewage tank, the top of the cabinet body is fixedly connected with the bottom of the water collection box, the left side of the cabinet body is fixedly connected with the outer side of the exhaust fan, and the impurity prevention mechanism comprises a sealing plate. The invention relates to the technical field of electric power. The electric power cabinet solves the problems that when electric power equipment runs, a large amount of current flows through the electric power equipment through a wire, so that a magnetic field exists in the equipment cabinet, dust in air is attracted by the magnetic force of the magnetic field and enters the cabinet body through the heat dissipation holes, and the dust is attracted to the inner walls of the heat dissipation holes by the magnetic force, so that the internal temperature of the equipment cabinet rises; and the problems of unstable operation of power equipment, potential safety hazards, equipment damage caused by the fact that rainwater easily enters the cabinet body through heat dissipation holes, long-term exposure of the equipment in the air, easy coverage of the heat dissipation holes by spider webs and the like, and further influence on heat dissipation in the power cabinet in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of electric power, in particular to an electric power cabinet. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are 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. [0003] According to Chinese patent CN112018644A, the present invention pro...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a power cabinet, which solves the problem that when the power equipment is running, a large amount of current flows through the power equipment through the wires, so that there is a magnetic field inside the equipment cabinet, and the dust in the air is subjected to the magnetic force of the magnetic field. Attraction enters the interior of the cabinet through the heat dissipation holes, and the dust is magnetically adsorbed on the inner wall of the heat dissipation holes, causing the internal temperature of the equipment cabinet to rise, making the operation of the power equipment unstable, and posing safety hazards. At the same time, rainwater can easily enter the cabinet through the heat dissipation holes If it is exposed to the air for a long time, the heat dissipation holes are easily covered by spider webs, which will affect the heat dissipation inside the power cabinet.
