In recent years, with the frequent occurrence of safety accidents in special dangerous places such as coal mines and chemical enterprises, the country's emphasis on safety production has gradually increased. Special electrical products such as flameproof and flameproof lamps are the key to safe production.

    Explosion-proof lamps are electrical products used in explosive environments. According to their explosion-proof types, they are mainly divided into: explosion-proof "d", "n", "e", "explosion-proof", "explosion-proof" and Or a composite type composite explosion-proof type composed of two or more explosion-proof types, etc. Its design, inspection, production, installation, use and maintenance must comply with GB3836 explosion-proof standard and related standards.

    Explosion-proof lamps, as flame-proof electronic products, have certain special characteristics. Because their luminous and heating characteristics are not easy to meet the requirements of explosion-proof electrical energy limit and temperature limit, special attention should be paid to the energy generated by them in the design and manufacturing process. control.

    It is well known that the "maximum surface temperature" in an explosive atmosphere is a key factor, which refers to the electrical equipment operating under the worst conditions allowed, the surface or any part of which may be reached, and may cause the surrounding explosive gas atmosphere. maximum temperature. As an electrical product that can quickly generate high temperature and heat, the "maximum surface temperature" is even more important for it. Therefore, for the testing organization of explosion-proof lamps, the temperature test is the most important and the most difficult operation in the test.

    One is the classification of explosion-proof lamps.

    a Explosion-proof fluorescent lamps are divided into explosion-proof incandescent lamps, explosion-proof high-pressure mercury lamps, explosion-proof sodium lamps, explosion-proof metal halide lamps, LED explosion-proof lamps, etc. according to the type of light source;

    b According to the installation type, it is divided into: ceiling explosion-proof light, wall-suction explosion-proof light, hanging explosion-proof light, embedded explosion-proof light;

    c According to the use, it can be divided into: explosion-proof lighting fixtures, explosion-proof lighting fixtures, explosion-proof signal lights, explosion-proof emergency lighting, explosion-proof mobile lights;
