Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical cabinets, in particular to an electrical cabinet with a power-off protection mechanism. BACKGROUND

[0002] An electrical cabinet is a cabinet made of steel for protecting components and devices from working abnormally. The manufacturing materials of an electrical cabinet are generally divided into hot-rolled steel plates and cold-rolled steel plates. The cold-rolled steel plate is more flexible than the hot-rolled steel plate and is more suitable for the manufacturing of an electrical cabinet. The electrical cabinet is widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc.

[0003] Most of the electrical devices equipped with solar panels on the market currently adopt a fixed installation method for the solar panels. Due to the rotation of the earth and the continuous change of the position of the sun in the sky, the design of the fixed angle makes the solar panels unable to always face the sunlight, thereby seriously affecting the absorption efficiency of solar energy. This not only wastes valuable solar energy resources, but also limits the stability and sustainability of the energy supply of the entire electrical system, increases the dependence on traditional power grids or other backup power sources, and cannot achieve effective circuit protection mechanism when the electrical cabinet has a short circuit or excessive current.

[0004] During the long-time operation of electrical equipment, a large amount of heat is generated. If the heat cannot be effectively dissipated in time, the internal temperature will rise, thereby affecting the performance and service life of electronic components and devices. In complex use environments, especially in outdoor places, these heat dissipation holes are easily disturbed by external factors. For example, in windy and sandy weather, the sand particles carried in the air will gradually accumulate around the heat dissipation holes and enter the holes, causing blockage. Once the heat dissipation holes are blocked, air circulation is blocked, and heat cannot be normally discharged, which will cause local overheating in the equipment interior, and the heat dissipation of each part becomes uneven. Under such harsh working conditions for a long time, electronic components and devices may be damaged due to high temperature, such as capacitor bulging, chip failure, etc. In severe cases, it may even cause fire accidents and other safety accidents, causing huge economic losses and safety hazards to the users. Moreover, the traditional cleaning method of the heat dissipation holes is mainly manual maintenance, which is not only time-consuming and labor-intensive, but also difficult to ensure timeliness and thoroughness, and cannot meet the demand for long-term stable operation of the equipment in complex and variable environments.

[0005] When a large amount of sand and dust is carried by strong wind, the existing electrical devices can only passively withstand it. On the one hand, the sand and dust easily block the heat dissipation holes. On the other hand, the open heat dissipation holes also allow the sand and dust to directly enter the interior of the equipment, adhere to the surface of the circuit board and other precision components, wear the mechanical transmission parts, and reduce the insulation performance of the equipment, further aggravating the aging and failure probability of the equipment.

[0006] Therefore, the application provides an electrical cabinet with a power-off protection mechanism to solve the above problems. SUMMARY
