An internal circulation cooling power distribution cabinet

Abstract

The invention discloses an internal circulation cooling distribution box which comprises a box body. The box body is internally provided with a cavity with is provided with a cooling chamber and an electric apparatus room in the vertical direction, the electric apparatus room is divided into multiple placing areas through partition plates, sliding rails corresponding to the partition plates are arranged on the inner side wall of the electric apparatus room, the two ends of the partition plates are located on the sliding rails respectively, a cooling pipe is arranged on the rear side wall of the electric apparatus room, cable grooves are formed in the inner side walls of the placing areas, multiple first vent holes are formed in the outer side wall of the box body, an electric apparatus room door is hinged to the side wall of the electric apparatus room, multiple monitoring devices are arranged on the internal surface of the electric apparatus room door, and the cooling chamber is internally provided with a cooling case. Accordingly, independent operation of cooling devices and electrical components is achieved, the cooling effect of the distribution box is effectively improved, water proofing and damp proofing can be achieved, the service life of the electrical components is prolonged, the automation degree is high, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of electrical automation, in particular to an internal circulation cooling power distribution cabinet. 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. The heat dissipation device in the existing power distribution cabinet...

AI Technical Summary

Problems solved by technology

The heat dissipation device in the existing power distribution cabinet has no obvious effect and cannot meet the cooling requirements. At the same time, the heat dissipation device is generally installed in the cabinet together with the electrical components. The power distribution cabinet is easy to get wet and water in the rainy season, and cannot be effectively waterproof and moisture-proof
