An electrical explosion-proof cabinet is a device specially designed to safely control and protect electrical systems in flammable and explosive environments.

The basic functions and importance of electrical explosion-proof cabinets：

• Basic functions: Electrical explosion-proof cabinets are mainly used to prevent explosions caused by sparks or heat generated by electrical equipment. They are suitable for explosive hazardous environments such as petroleum and petrochemical, chemical, brewing, medicine, paint, textile, printing and dyeing, and military facilities. Its working principle is to form a micro-positive pressure environment through a positive pressure purge control system to prevent external flammable gases from entering, thereby protecting internal electrical components.
• Importance: In hazardous environments such as petrochemicals, the use of electrical explosion-proof cabinets is essential to ensure the safety of personnel and equipment in the workplace. They can effectively prevent fire and explosion accidents, reduce risks in the production environment, and meet strict industrial safety standards.

Types and structural features of electrical explosion-proof cabinets：

• Type: Common electrical explosion-proof cabinet models on the market include BZY series explosion-proof positive pressure control cabinet, BKZ series explosion-proof control box, BJX series explosion-proof junction box, etc. These products combine explosion-proof technology, electronic technology, precision processing technology and other advanced technologies.
• Structural features: Electrical explosion-proof cabinets are usually made of high-strength materials, such as steel plate welding or stainless steel, with excellent explosion-proof performance and anti-corrosion capabilities. The cabinet design takes into account the heat dissipation requirements, internal air pressure balance, and safe power-off measures in emergency situations.

Application scope and selection points of electrical explosion-proof cabinets：

• Application scope: Electrical explosion-proof cabinets are widely used in flammable and explosive environments such as coal mines, oil mining, refineries, chemical plants, pharmaceutical plants, etc., especially in key areas where explosion risks need to be strictly controlled.
• Selection points: When choosing an electrical explosion-proof cabinet, you should consider its safety, applicable explosive and dusty environments, temperature groups, protection levels and other factors. For example, different series of explosion-proof cabinets are suitable for different hazardous areas and explosive gas environments, and users should choose according to specific application scenarios.
