Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, and particularly relates to an electrical cabinet with a fire prevention function. Background Technique

[0002] An "electrical cabinet" is an enclosed device used to protect and control components of a power system. It is mainly made of steel materials, and common manufacturing materials include hot-rolled steel plates and cold-rolled steel plates. Among them, cold-rolled steel plates are more suitable for manufacturing electrical cabinets because of their softer material. Electrical cabinets are widely used in industries such as chemical industry, environmental protection, power system, metallurgy, industry, nuclear power, fire safety monitoring, and transportation.

[0003] Power switches, fuses, relays, AC and DC motor controllers, transformers and other electronic components can be installed inside the electrical cabinet. It can protect electrical equipment, quickly cut off the circuit in case of abnormal conditions such as current overload and short circuit, avoid the occurrence of major accidents, and at the same time can control the working state of electrical equipment, such as operations like turning on, turning off, and starting. In addition, the electrical cabinet also has the functions of ventilation, heat dissipation and filtration to improve the service life of electrical components.

[0004] With the development of social economy, the use of electricity is becoming more and more popular, which makes the use of electrical cabinets more and more. Since there are many electrical components inside the electrical cabinet, if fire prevention is not paid attention to, it will cause certain safety hazards, and in serious cases, it may even lead to the explosion of the electrical cabinet.
