What Are the Principles of Explosion-proof Smartphones?

As the main supplier of energy such as gasoline, kerosene, diesel, heavy oil, and natural gas, petrochemical companies often work in explosive hazardous areas. A slight mistake can cause an explosion. Flameproof mobile phone can meet the needs of explosion-proof hazardous areas.

Understanding of explosion-proof smartphones

For some industrial products used in special environments where there are a large amount of flammable and explosive gases or dust, such as underground mine phones for mine industry. explosion-proof certification is generally required to ensure the safety of the product during use and the personal safety of the user. Explosion-proof smartphones use internal components to limit various parameters of electrical equipment circuits, or take protective measures to limit the discharge energy of circuit sparks and heat energy, so that the electrical effects produced in normal operation and specified fault conditions cannot ignite the explosive mixture in the surrounding environment, thereby achieving electrical explosion-proof. The circuit of such electrical equipment itself has explosion-proof performance, which is inherently safe, and is called intrinsically safe. The mobile communication device that adopts intrinsically safe circuit is called intrinsically safe security camera. The explosion-proof design of explosion-proof smartphones makes the circuit itself comply with the use of explosive hazardous gases or explosive mixture places, so there is no need to conduct external shielding and isolation treatment on the devices, and it has great advantages in terms of product weight, volume, operation, and other aspects.

Choosing explosion-proof smartphones

When choosing explosion-proof smartphones, it is necessary to know that ordinary smartphones can also generate explosion hazards in dangerous places. So how to make them explosion-proof? According to the conventional explosion-proof processing method, smartphones can be designed as intrinsically safe type,  spark-free type, explosion proof intercom system and explosion proof walkie talkie. "Ia" intrinsically safe explosion-proof smartphones can be used in dangerous places of zones 0, 1, and 2, while "Ib" intrinsically safe explosion-proof smartphones can be used in dangerous places of zone 1 and zone 2. Spark-free explosion-proof smartphones can only be used in dangerous places of zone 2.

Explosion-proof smartphones can only be used normally in hazardous environments, such as viewing information and answering calls, and should not be directly disassembled in the workplace. Although the internal structure eliminates thermal effects and electrostatic phenomena, the manual operation of disassembling the battery can still cause electrostatic sparks, which may cause explosions. Charging is also not allowed. The original charger should be properly stored and charged outside the workplace. Do not replace the charger at will, which may damage the internal current circuit of the phone.
