Abstract

The invention provides a power distribution cabinet which comprises a cabinet body, a cabinet door and a base. The cabinet door and the cabinet body are connected through a rotating shaft type movable hinge. Four supporting legs are arranged on the base and provided with four wheels. A square window is formed in the upper portion of the cabinet door and used for installing a display instrument. A circular through hole is formed in the cabinet door and used for installing a control button. A handle made of insulating material is arranged on the cabinet door and used for pushing and pulling the cabinet door. The power distribution cabinet is characterized in that the opening angle of the cabinet door is larger than 120 degrees, the position, close to the edge of the cabinet door, of the inner wall of the cabinet door is provided with an installation box, and a pressing type soft magnetic switch is arranged in the installation box. The power distribution cabinet is convenient to overhaul; due to the cooling window, heat in the power distribution cabinet can be taken away in time, an electrical device in the cabinet body is protected, and the service life of the device in the cabinet body is prolonged; large-granularity dust in air can be prevented from entering the cabinet body, and it is avoided that after dust is accumulated on the surface of the electric device, normal work of the electric device is influenced.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a power distribution cabinet. Background technique [0002] The power distribution cabinet is a kind of electrical equipment and the general control center of various electrical appliances. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch, and each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. load shedding. In the existing technology, as more and more electrical components and wires and cables need to be accommodated inside the power distribution cabinet, the volume of the power distribution cabinet also becomes larger. The existing power distribution cabinets are often designed to be relatively close...
