Why do we use an explosion-proof camera?

The initial demand for anti-explosion requirements for electrical equipment came from coal mines, which were very prone to explosions or burning because of gas under the coal mines. With the development of industrialization, the demand for explosion-proof requirements for electrical equipment has expanded to various fields - petroleum, chemical, pharmaceutical, marine, aerospace, metallurgical, scientific research and military industries. The demand is even worse, the requirements are different, the pertinence is stronger, especially the rapid development of China's petrochemical industry, accelerating the development of explosion-proof industrial monitoring products, and a large number of electrical equipment is used in production. The electrical equipment, safety equipment and lighting fixtures used will inevitably produce sparks, arcs and high temperatures that are allowed under normal conditions. However, due to factors such as site conditions, the concentration of the mixture at the risk of explosion may increase continuously, reaching a certain concentration. The source of the detonation - electric spark, arc and high temperature detonation, the consequences are unimaginable. In recent years, many explosion accidents have occurred. The more serious explosions are: (2015.8.12) Tianjin Binhai New Area explosion accident, (2016.8.2) Jiangsu Kunshan factory explosion accident, (2017.4.12) Chongqing oil storage tank Explosion accident, (2017.12.10) Jiangsu Lianyungang chemical enterprise workshop explosion and so on.

Many industrial enterprises or research departments, such as petroleum, chemical, gunpowder, natural gas, etc., often leak and overflow a variety of flammable, explosive gases, liquids and during the process of experimentation, production, processing, transportation and storage. A variety of dust and fiber, when mixed with air, will become a mixture that is prone to explosion hazard, and the surrounding area is also a dangerous place of explosion. When the concentration of explosives reaches the critical point of the explosion, once the source of the detonation occurs, serious accidents such as explosions and fires may occur, causing casualties and property losses. Therefore, cameras, electric pan/tilt, junction boxes and other equipment installed in hazardous areas must be explosion-proof; and electrical explosion-proof types can be divided into explosion-proof, intrinsically safe, and encapsulated types. At present, most of the explosion-proof cameras on the market use explosion-proof type, and explosion-proof is the most direct and economical explosion-proof type. Explosion-proof cameras, explosion-proof high-speed balls, explosion-proof junction boxes and other explosion-proof monitoring equipment produced by Shenzhen Rongfang Company are also equipped with explosion-proof structure.
