day, with the little sister Xiaoqian of Sunzen Lighting, we will take you  understand the field of industrial lighting, a very subdivided field-explosion-proof lighting. The following text is the definition of an explosion-proof lamp on an encyclopedia: an explosion-proof lamp refers  a dangerous place where combustible gas and dust exist, and can prevent the arc, sparks and high temperature that may be generated inside the lamp. The flammability in the surrounding environment Gas and dust, so as  meet the requirements of explosion-proof lamps. Also called explosion-proof lamps, explosion-proof lighting. Different flammable gas mixture environments have different requirements for the explosion-proof grade and explosion-proof form of the explosion-proof lamp. For details, please refer  GB3836 and IEC60079.

　　The hazardous location area is divided in the national explosion-proof standard GB3836:

　　According  the different physical states of the substances present in the places, hazardous places are divided in explosive gas environments and combustible dust environments.

　　According  the length of time the hazardous substances exist in the location, the two types of hazardous locations in different physical states are divided in three zones, namely: for explosive gas environments, zone 0, zone 1, and zone 2; for combustible dust environment, zone Zone 20, Zone 21 and Zone 22.

　　For explosive gas environment, GB 3836.14—2000 standard stipulates:

　　Zone 0: The place where explosive gas environment occurs continuously or exists for a long time.

　　Zone 1: A place where an explosive gas environment may occur during normal operation.

　　Zone 2: During normal operation, it is impossible  have an explosive gas environment. If it occurs, it will happen occasionally and only exist for a short time.

　　Here, "normal operation" refers  the state in which normal driving, running, spping, loading and unloading of flammable products, opening and closing of closed container lids, safety valves, discharge valves, and all facry equipment are working within their design parameters .

　　Three zones are divided according  the time of existence of hazardous substances and gases each year:

　　Long-term existence (greater than 1000h/year) Zone 0

　　Exist during normal operation (10-1000h/year) Zone 1

　　Exist only when it is abnormal (less than 10h/year) Zone 2

　　According  the national explosion-proof standard GB3836, the equipment category and electrical equipment used in explosive gas atmosphere are classified:

　　Electrical equipment for explosive gas atmosphere is divided in:

　　Class I: electrical equipment used underground in coal mines;

　　Class II: electrical equipment used in facries;

　　Class II flameproof "d" and intrinsically safe "i" electrical equipment are divided in IIA, IIB, and IIC categories.

　　Briefly 90% of Class II non-mining explosion-proof electrical equipment is used in petroleum, offshore oil, petrochemical, chemical industry and pharmaceutical industries (referred  as petrochemical industry). The hazardous chemical workplaces in these industries are flammable and explosive. There are many types of gases/vapors, the process and equipment of production, srage, and transportation are complex and changeable, and there are many types of release sources, and it is difficult  analyze and determine explosion risk facrs. Therefore, the selection, installation, use and maintenance of explosion-proof electrical equipment are much more complicated than mine-use explosion-proof electrical equipment. Selection of explosion-proof electrical equipment: First, select the corresponding electrical explosion-proof type  meet the hazardous area divided by the hazardous location; second, select the level and temperature group of the explosion-proof electrical equipment according  the types of flammable and explosive gases/dust that may exist in the hazardous environment The third is  consider the impact of other environmental conditions on the explosion-proof performance (for example: chemical corrosion, salt spray, high temperature and humidity, sand, dust, rain, or vibration); the fourth is  ensure the particularity of installation, use and maintenance; the fifth is  choose explosion-proof Certificate of conformity and products certified by the country.

　　(1) According  the "Code for the Design and Construction of Gas Stations for Aumobile Gas Stations" (GB50156-2002) (2006 edition), the lighting fixtures of buildings in explosive areas in gas stations must be explosion-proof.

　　(2) Miner's lamp is the abbreviation of mining lamps or industrial and mining lamps.  achieve healthy and sustainable development, mining enterprises must transform and upgrade, and use technological transformation as a means  improve product quality, reduce production costs, and reduce energy consumption and pollutant emissions . Miner's lamp is suitable for the dangerous environment of the coal mine industry with explosive gas mixtures such as methane and coal dust; it is suitable for fixed flood lighting in underground roadways and chambers of coal mines.

　　Mine lighting case: The current status and existing problems of underground lighting in coal mines in my country. A new concept of green lighting in coal mines is proposed with the main goals of improving the efficiency of coal mine lighting, saving energy, reducing light pollution, and improving coal mine production safety and efficiency. Its main connotation is  use high-efficiency energy-saving lighting fixtures such as LED  replace traditional low-efficiency lighting fixtures, and  adopt scientific lighting design and control methods  improve lighting power efficiency and lighting quality.

　　(3) Copper facry lighting: my country's metallurgical enterprises include the complete departments of mining, sintering, coking, steelmaking, steel rolling and corresponding ferroalloys, refracry materials, carbon products, geological prospecting, engineering design, building construction, scientific research, etc. Industrial system.

　　Lighting is a key auxiliary production facility for metallurgical enterprises, and regulations put forward higher requirements for facry lighting. Not only do they have higher requirements for traditional indicars such as brightness and glare, but also for light uniformity, color rendering index, energy saving, and long life. , Product matching combination, etc. have put forward higher standards and requirements.

　　Therefore, the lamps must meet the objective conditions of high temperature, strong vibration, dust, mixed gas and other objective conditions.

　　Power plant lighting: A power plant is a facry that converts the energy of various power sources in electrical energy. According  the form of energy used, it can be divided in thermal power plants, hydroelectric power plants, nuclear power plants, geothermal power plants, wind power plants, etc. Power plant lighting has put forward higher requirements, not only in brightness, glare and other traditional indicars, but also in terms of light uniformity, color rendering index, energy saving, long life, and product matching combination. High standards and requirements.

　　In summary, explosion-proof lamps are generally used in more dangerous areas, such as mines, mines, chemical plants, gas stations, steel plants, power plants, etc. Therefore, the significance of the existence of LED explosion-proof lights is  make the production of lighting safer and more energy-saving for companies that need it. The most important of these is  make these areas safer. Safe production is a pic that every company emphasizes with workers every day. Safety should not be negligent, and safety must be paid attention . LED explosion-proof lights are an important part of basic safety construction. Link. Speaking of this, explosion-proof lamps are not only a general lighting product, but also the cornersne of the lives of countless people. Here, we also call for explosion-proof lamps and lanterns designers and manufacturers  design and produce conscientiously; users of explosion-proof lamps must use them correctly and choose
