1. Definition and Function
Explosion-proof electric control cabinet is an electrical equipment that can be used safely in explosive environments, it adopts special explosion-proof structure and materials, which can effectively prevent explosion accidents caused by electrical sparks, arcs and high temperatures, so as to ensure production safety. Such products are widely used in petroleum, chemical, electric power, coal, medicine and other industries with flammable and explosive environments.
Second, product features
Explosion-proof performance: Through special explosion-proof design and materials, the safe operation of electrical equipment in flammable and explosive environments is ensured, and the fire and explosion caused by electrical sparks are effectively prevented.
Fire performance: Even if a fire occurs in the cabinet, the fire can be quickly controlled within a certain range to prevent the fire from spreading.
Dustproof, waterproof and anti-corrosion: It can adapt to the harsh industrial environment and ensure the long-term stable operation of the equipment.
Versatility and flexibility: It can be customized according to the specific needs of different industries to meet the requirements of use in different environments.
3. Product classification
According to the different explosion-proof levels and uses, explosion-proof electric control cabinets can be divided into many types, such as:
Conventional type: suitable for general flammable gas environment, explosion-proof grade is ExdI.
Increased safety type: suitable for environments containing flammable gases, explosion-proof level is ExdIIAT4.
Flameproof type: suitable for environments containing flammable liquid and gas mixtures, explosion-proof class ExdIICT6.
In addition, there are different types of explosion-proof electric control cabinets such as positive pressure type, negative pressure type, and intrinsically safe type to meet the needs of use in different environments.
Fourth, the product structure
The structure of the explosion-proof electric control cabinet mainly includes the shell, the distribution cabinet, the instrument panel, the console, the isolation switch, the cable joint and other parts. The shell is generally made of cast aluminum alloy material, and the surface is sprayed with plastic, which has good anti-corrosion, waterproof and dustproof properties. Various electrical components, such as circuit breakers, contactors, relays, transformers, etc., are provided inside the distribution cabinet, instrument panel and console to complete various electrical control and protection functions.
5. Use and maintenance
Inspection before use: Before using the explosion-proof electric control cabinet, check whether its appearance and internal electrical components are normal to ensure that there is no fault.
Matching of use environment: When using, attention should be paid to whether the explosion-proof level and use environment of the explosion-proof electric control cabinet are consistent with the use environment, so as to avoid danger caused by improper use.
Regular inspection and maintenance: Regularly inspect and maintain the explosion-proof electric control cabinet to ensure its normal operation. This includes checking the connections of electrical components, cleaning internal dust, etc.
Avoid overload: Overload should be avoided during use to prevent accidents caused by overheating of electrical components.
It is forbidden to change without permission: the electrical components shall not be replaced or the structure of the explosion-proof electric control cabinet shall not be changed without permission, so as not to affect its explosion-proof performance.
6. Application scenarios
Explosion-proof electric control cabinets are widely used in the following scenarios:
Oil & Gas Storage, Transmission & Processing: Protecting Equipment from Disasters such as Explosions.
Chemical plants, oil refineries: ensure the safe operation of electrical equipment in flammable gases and steam.
Mine electrical equipment: prevent sparks caused by electrical faults and ensure the safety of coal mining.
Marine and marine sector: Prevent explosions caused by seawater, fuels and other flammable substances.
Food processing and beverage production: Explosion-proof measures when flammable gases or solvents are used in specific processes.
Drug production and laboratory environments: Ensure the safety and stability of equipment.
