Electric control power distribution cabinet with moisture-proof and cooling functions

Abstract

An electric control power distribution cabinet with moisture-proof and cooling functions of the present invention comprises a power distribution cabinet shell and a shell base arranged at the bottom of the power distribution cabinet shell, the front and rear side surfaces of the power distribution cabinet shell are both equipped with door body frames, and the two sides of each door body frame are equipped with the L-shaped cover body sliding grooves in the vertical direction. The L-shaped cover body sliding grooves are internally equipped with the movable cover bodies, the left side face and the right side face of the power distribution cabinet shell are both provided with heat dissipation cylinder assembling holes, a heat dissipation cylinder is arranged in each heat dissipation cylinder assembling hole. A semiconductor refrigeration piece is arranged in each heat dissipation cylinder, a transverse hole, a longitudinal hole and a vertical hole which are horizontally and vertically communicated are formed in the shell base, and the vertical holes, the transverse holes and the longitudinal holes are communicated with one another. By means of the scheme, the electric control power distribution cabinet with the damp-proof and cooling functions can achieve the damp-proof function, the noise reduction function, the cooling function and the waterproof function on the power distribution cabinet at the same time, the safety coefficient of the power distribution cabinet can be greatly increased, and the service life of the power distribution cabinet can be greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of electric control power distribution, in particular to an electric control power distribution cabinet with moisture-proof and cooling functions. Background technique [0002] Electric control distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Power distribution cabinets are collectively referred to as motor control centers. In some occasions, 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 should provide protection, monitoring and control for the load. [0003] The electric control distribution cabinet has the advantages of small size, easy installation, special tec...

AI Technical Summary

Problems solved by technology

[0004] For the power distribution cabinet used outdoors, when the internal circuit components continue to work, the temperature inside the power distribution cabinet will rise. Excessive temperature in the power distribution cabinet will seriously affect the service life of the internal circuit components. Electric cabinets are prone to exposure to wind and sun. Outdoor distribution cabinets are only simple iron shells and cement bases. On the one hand, they cannot effectively dissipate heat and prevent moisture. It will also cause relatively loud noise, which can easily cause people to panic. When the above problems cannot be solved, the service life of the power distribution cabinet will often be shortened.

[0005] Chinese patent document CN 108711755 A discloses a heat dissipation power distribution cabinet, including a cabinet body heat dissipation power distribution cabinet, the top of the cabinet body heat dissipation power distribution cabinet is provided with an air inlet heat dissipation power distribution cabinet, and the air inlet is provided with an air inlet cover. The two side walls of the body heat dissipation power distribution cabinet are provided with heat dissipation windows and heat dissipation power distribution cabinets, and the heat dissipation windows are provided with heat dissipation window covers. The electric cabinet is located inside the heat dissipation power distribution cabinet of the cabinet body. The heat dissipation power distribution cabinet with air outlet is installed at the bottom of the heat dissipation power distribution cabinet of the cabinet body. There is a heat dissipation power distribution cabinet with a cabinet door on the electric cabinet, which can only dissipate heat for the power distribution cabinet. At the same time, due to the air inlet, a large amount of oxygen and water vapor will enter the interior of the power distribution cabinet, and the oxygen can be released inside the power distribution cabinet. Oxidation of components and components, water vapor will condense inside the power distribution cabinet, causing internal short circuit and causing safety accidents
