Power distribution cabinet shell for construction site

Abstract

The invention discloses a power distribution cabinet shell for a construction site, and relates to the technical field of power distribution cabinets. The power distribution cabinet shell for the construction site comprises a shell body, wherein a sealing door plate is movably installed on the front side of the shell body, a heat dissipation device penetrates through the side face of the shell body and is fixed to the side face of the shell body, and a plurality of heat dissipation channels are formed between the two sides of the heat dissipation device in a penetrating mode. According to the power distribution cabinet shell for the construction site, a filter screen is arranged in the heat dissipation channel, so that air in the heat dissipation channel can be filtered, dust in the air is attached to the surface of the filter screen, and the dust in the air is prevented from influencing the service life of a power distribution cabinet; and the vibration of large-scale equipment on the construction site can enable a filter screen cleaning mechanism to automatically clean the filter screen, so that the influence on the heat dissipation effect of the power distribution cabinet caused by excessive dust accumulated on the filter screen is prevented, and the service life of the power distribution cabinet is prolonged on the premise that the heat dissipation effect of the power distribution cabinet is not influenced.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a housing of a power distribution cabinet for a construction site. Background technique [0002] Power distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, and 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] In the construction site, it is necessary to use...

AI Technical Summary

Problems solved by technology

[0003] In the construction site, it is necessary to use power supply equipment to supply power to various large-scale construction equipment. At the same time, the power distribution cabinet is also an indispensable power supply control device. However, the air near the construction site contains a lot of dust, which will enter the power distribution cabinet through the heat dissipation holes, and accelerate the damage of the internal components of the power distribution cabinet, which has certain defects.
