So what is an explosion-proof lamp? Where must explosion-proof lamps be used?

The definition of explosion-proof signs in explosion-proof lamps:

The explosion-proof mark in explosion-proof lamps refers to the marks used to describe the explosion-proof grade, temperature group, explosion-proof type and applicable area of explosion-proof lighting lamps.

Explosion-proof mark description:

Explosion-proof lighting equipment is in accordance with the requirements of GB 3836. The explosion-proof mark of explosion-proof lighting equipment includes:

Explosion-proof type + equipment category + (gas group) + temperature group

1. Explosion-proof type

According to the explosion-proof measures taken, explosion-proof lamps can be divided into explosion-proof type, increased safety type, intrinsically safe type, positive pressure type, oil immersed type, sand-filled type, encapsulated type, n type, special type, dust explosion-proof type, etc. . Their identification is shown in Table 1.

Explosion-proof lamp refers to a lamp used in dangerous places where flammable gas and dust exist, and can prevent the arc, spark and high temperature that may be generated inside the lamp from igniting the flammable gas and dust in the surrounding environment, so as to meet the requirements of explosion-proof. Also called explosion-proof electrodeless 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 induction lamp

Such as liquefied gas stations, chemical plants, paint spray booths, polishing and polishing workshops, automobile wheel polishing workshops, coal washing plants, garbage power plants, gas stations, gas filling stations, flour mills, ammonia reservoirs, firecracker warehouses, artillery rooms, steel plants, gas Stations, paint depots, oil depots, clothing factory depots, chemical depots, fuel depots, fireworks workshops, metal polishing workshops, magnesium powder polishing workshops, aluminum powder polishing workshops, tobacco warehouses, paper mills, dye rooms, pharmaceutical factories, thermal power plants, metallurgy Explosion-proof lights are needed in flammable, explosive, and dusty air environments such as factories, coal mine tunnels, and coal storage areas.

Specializing in the production of explosion-proof LED lights, explosion-proof fluorescent lamps, explosion-proof electrical appliances, explosion-proof distribution boxes
