Description

Technical Field

[0002] High and low voltage distribution cabinet is a device used to distribute and control electric energy in power system, which is commonly found in factories, buildings, power stations and other places. It protects electrical equipment and ensures the safe operation of power system by reasonably distributing electric energy. High and low voltage distribution cabinet is divided into high voltage distribution cabinet and low voltage distribution cabinet, which are used to handle high voltage and low voltage power transmission respectively.

[0003] When high and low voltage distribution cabinets are in use, they will emit a lot of heat. Most of the existing high and low voltage distribution cabinets dissipate heat through heat dissipation holes or cooling fans. However, the air contains moisture, especially in some southern cities, where the humidity is relatively high. Traditional heat dissipation methods will introduce moisture into the cabinet. Long-term use will cause damage to the internal components of the cabinet. Most of the existing equipment dehumidifies by adding desiccant. The use of desiccant requires frequent replacement by staff, which is cumbersome. Summary of the invention
