Description

Technical Field

[0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment. Some electrical components are used in combination and installed in a transformer cabinet for use. The transformer cabinet is a box in the power system where the voltage and current of electric energy are transformed, concentrated and distributed. Its main purpose is to ensure the quality of electric energy and the safety of equipment. The transformer cabinet plays a vital role in the power system. By transforming, concentrating and distributing electric energy, it ensures the stability and safety of power supply. This type of equipment usually includes high-voltage distribution cabinets, low-voltage distribution cabinets, etc., which play a key role in the process of power transmission, distribution and use.

[0003] Power substation plays a vital role in the power system. It is used to install and protect various electrical equipment. However, when the existing power substation with high heat dissipation efficiency is used in the later stage, some power substations have the problem of low heat dissipation efficiency during use. With the operation of electrical equipment, a large amount of heat will be generated. If the heat cannot be dissipated in time and effectively, the temperature of the electrical equipment will be too high. Some equipment has heat dissipation holes for natural heat dissipation, but dust will also enter the ventilation mechanism. After long-term use, the heat dissipation holes will be blocked, resulting in a decrease in heat dissipation capacity. Therefore, manual dust removal is required. However, the dust removal process of these power cabinets is relatively difficult, which affects their normal operation and even shortens the service life of the equipment, and may also cause safety accidents.
