Explosion proof control cabinet is a special control equipment used in flammable and explosive environments, with functions such as explosion prevention, fire prevention, and corrosion prevention. It is widely used in places with explosive gases or dust such as petroleum, chemical, and coal mines, effectively preventing explosion accidents by isolating hazardous sources and combustion aids.

The outer shell of explosion-proof control cabinets is usually welded with steel plates or cast aluminum alloy, and internal components with explosion-proof functions, such as input/output isolation barriers and intrinsic safety power supplies, are installed to ensure that external circuit problems will not be caused in the event of electrical component failures.

Advantages And Characteristics：

• High safety: The explosion-proof cabinet adopts special design and materials, which can effectively prevent accidents such as fires and explosions, and ensure the safety of personnel and equipment.

• Comprehensive protection: Explosion proof cabinets have various safety protection features such as fire prevention, waterproofing, and explosion prevention, which can prevent harmful substances such as odors and pollutants from spreading to the surrounding environment in the working environment.

• Clear explosion-proof rating: Explosion proof cabinets are classified into European made explosion-proof rating and American standard explosion-proof rating according to different explosion-proof requirements, ensuring safety in different environments.

• Strict design requirements: In addition to basic explosion-proof functions, explosion-proof cabinets also need to consider safety performance such as preventing electrical fires, leakage, lightning, insects and ants, dust, moisture, and corrosion.

• Sturdy structure: The outer shell of explosion-proof cabinets is generally made of welded steel plates or cast aluminum alloy, with high-voltage electrostatic spraying. The overall structure is composed of a composite structure of explosion-proof and increased safety shells.

• Explosion proof internal components: The components installed inside the explosion-proof cabinet also have explosion-proof functions. Even if there is a malfunction or problem with the internal electrical components, it will not affect external sensors or other electrical circuits.

Application area:

• Petrochemical industry: In the petrochemical industry, there are a large number of flammable and explosive materials, such as gasoline, diesel, and natural gas. Positive pressure explosion-proof cabinets use an internal ventilation system to pressure clean air from outside the cabinet into the interior, ensuring that the pressure inside the cabinet remains consistently higher than the external environmental pressure. This effectively isolates and dilutes flammable and explosive gases, reducing the risk of fire and explosion.

• Coal industry: The production environment of the coal industry often contains flammable and explosive substances such as coal dust and gas. The application of positive pressure explosion-proof cabinets in the coal industry is mainly used for the protection and monitoring of underground electrical equipment, which can effectively prevent external flammable and explosive gases from entering the cabinet, thereby ensuring the safe operation of electrical equipment.

• Pharmaceutical industry: The pharmaceutical industry has extremely high requirements for the safety of the production environment, as any minor pollution or malfunction may affect the quality and safety of drugs. The application of positive pressure explosion-proof cabinets in the pharmaceutical industry can provide a safe and clean production environment, ensuring drug quality and production safety.

• Substations, power plants and other places: In these places, positive pressure explosion-proof cabinets are used to protect key electrical equipment and control systems from external environmental influences, ensuring the stable operation of the power system.

• High risk industrial sites: including explosive gas mixture risk sites (Zone 1, Zone 2), combustible dust environments (Zone 20, Zone 21, Zone 22), and specific temperature groups (T1-T6).

• Outdoor application: The outdoor explosion-proof positive pressure cabinet is designed specifically for outdoor flammable and explosive environments, with features such as rain, dust, and sun protection. It is widely used in outdoor places such as petroleum, chemical, and pharmaceutical industries where flammable and explosive gases, dust, or fibers exist.
