Anti-corrosion power cabinet with shielding layer

Abstract

An anti-corrosion power cabinet with a shielding layer includes stand columns, a box body, a fan, an electrical element and a mounting plate, left and right ends of the bottom of the box body are equipped with the stand columns, the fan is mounted above the top of the box body, the mounting plate is mounted on the inner side of the box body through bolt connection, the electrical element is mounted on the mounting plate, and the box body includes an insulating layer, a shielding layer, a metal layer and an anti-corrosion layer in sequence from inside to outside. The anti-corrosion power cabinet with a shielding layer overcomes defects of the prior art, an original metal box body structure is improved, the insulating layer, shielding layer, metal layer and anti-corrosion layer are adopted and are glued to perform one-time extrusion molding, the formed box body has the characteristics of light mass, corrosion resistance and an anti-distortion capability, an effect of prolonging the service life of the power cabin, environment protection and energy conservation and the like, the performance is excellent, and thus the anti-corrosion power cabinet is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of power cabinets, in particular to a corrosion-resistant power cabinet with a shielding layer. Background technique [0002] The power cabinet refers to the combination of electrical control cabinets that provide power for the normal operation of the entire machine, including contactors, frequency converters, high-voltage cabinets, transformers, etc. The power cabinet has the functions of providing power to electrical equipment, starting electrical equipment, and detecting whether the equipment is operating normally. The installation of the power cabinet is divided into two types: hanging type and floor type. The floor type power cabinet has a line through hole at the bottom, which communicates with the underground wire groove during installation. When a floor-standing power cabinet is used, the internal temperature of the power cabinet is relatively high during normal operation. The humidity on the groun...

AI Technical Summary

Problems solved by technology

When a floor-standing power cabinet is used, the internal temperature of the power cabinet is relatively high during normal operation. The humidity on the ground is high, which causes the moisture in the air to penetrate into the power cabinet from the bottom. When the air enters the power cabinet, water droplets will form. The ordinary drying box equipment can no longer meet the absorption and drying function, and it will still cause electrical shock after a long time. Equipment short circuit, leakage, accelerated aging, affect the safe operation of electrical equipment, and there are great potential safety hazards. In addition, the structure of the power cabinet in the prior art is complicated, which is not conducive to the maintenance work. The existing power cabinet does not have The effect of shielding and corrosion resistance is not good, therefore, a new technical solution needs to be provided to solve the problem
