1. Definition of explosion-proof distribution box

Explosion-proof distribution box is an electrical equipment used to distribute and control electric energy. It is mainly used in flammable and explosive places such as petroleum, chemical industry, and gas. It has various structural forms such as explosion-proof, explosion-proof, and increased safety to meet different use environments and safety requirements.

2. Design principles of explosion-proof distribution boxes

1. Safety: The design of explosion-proof distribution boxes should comply with relevant national standards and industry standards to ensure the safe use of equipment in flammable and explosive places.

2. Reliability: Explosion-proof distribution box certificates are required by national standards. The structural design should ensure that the equipment has good impact resistance, vibration resistance, and corrosion resistance to extend the service life of the equipment.

3. Economy: The design of explosion-proof distribution boxes should fully consider the cost of the equipment, and strive to reduce the production cost of the equipment while ensuring safety and reliability.

4. Aesthetics: The appearance design of the explosion-proof distribution box should meet the requirements of modern industrial aesthetics, making the equipment both safe and beautiful.

3. Design scheme of explosion-proof distribution box

1. Structural design: The structural design of the explosion-proof distribution box should adopt a flameproof structure to ensure that when the equipment explodes, the internal electrical components will not cause the spread of flames. At the same time, the shell of the device should be made of metal materials to improve the impact resistance of the device.

2. Selection of electrical components: The electrical components in the explosion-proof distribution box should be explosion-proof products, such as explosion-proof switches, explosion-proof fuses, etc. These components should have good explosion-proof performance and can be used safely in flammable and explosive places.

3. Wiring method: The wiring method of the explosion-proof distribution box should use terminal blocks or bolt connections to ensure the reliability of the electrical connection. At the same time, the terminal blocks of the equipment should have protective covers to prevent electrical components from being affected by the external environment.

4. Protection measures: The shell of the explosion-proof distribution box should adopt a sealed structure to prevent the external environment from affecting the electrical components inside the equipment. At the same time, the interior of the device should be equipped with ventilation holes to ensure that the temperature inside the device does not become too high.

5. Installation method: The installation method of explosion-proof distribution box should be fixed or mobile installation to meet different usage requirements. At the same time, the equipment should be equipped with mounting holes and bolt holes to facilitate user installation and maintenance.

4. Summary

Explosion-proof distribution box is an important safety equipment, and its design should fully consider factors such as safety, reliability, economy, and aesthetics. By adopting explosion-proof structure, selecting explosion-proof electrical components, using terminal connections, setting protective measures and installation methods, the safe use of explosion-proof distribution boxes in flammable and explosive places can be ensured.
