A dust-proof and heat-dissipating power distribution cabinet with an extension mechanism for electric power

Abstract

The invention provides a power distribution cabinet equipped with an extension mechanism for dust prevention and heat dissipation for electric power, relates to the technical field of power distribution cabinets, and solves the problem that the internal space of conventional power distribution cabinets is fixed and difficult to change, and when expanding equipment, additional power distribution is required. Cabinets, while adding or removing power distribution cabinets, some lines also need to be reconnected, which is not only troublesome, but also takes up a lot of space, and affects the normal operation of the equipment in use, including the main body of the power distribution cabinet; the power distribution The front end plane of the cabinet main body is equipped with a cabinet door by installing a hinge at the left end edge to rotate. In the present invention, since the left end of the bottom plane of the upper heat dissipation grid of the main body of the power distribution cabinet and the left end of the top plane of the lower end heat dissipation grid are respectively provided with L-shaped hanging grooves A, which can be matched with the inner cabinet and the inner card mechanism, so that the inner The cabinet can be drawn out for expansion, so as to adapt to the situation of expanding the line, making the power distribution cabinet more adaptable.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, more specifically, to a power distribution cabinet equipped with an extension mechanism for dust prevention and heat dissipation for electric power. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and 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 ...

AI Technical Summary

Problems solved by technology

[0004] Usually, the internal space of the power distribution cabinet is fixed and difficult to change. When expanding equipment, additional power distribution cabinets need to be added. When adding or removing power distribution cabinets, some lines also need to be reconnected, which is not only troublesome, but also takes up a lot of space. And affect the normal operation of the equipment being used
