Principle of explosion-proof lamp

Time:2022-05-20 Views:0

Principle: The principle of explosion-proof type According to the concept of explosion-proof and fire-proof type of European standard EN13463-1:2002 "Non-electrical equipment for explosive atmospheres - Part 1: Basic methods and requirements", the explosion-proof type is to take measures to allow internal explosions and prevent flames An explosion-proof type of transmission explosion is the most commonly used type of explosion-proof. Because the shell of this type of explosion-proof lamp is generally made of metal material, it has good heat dissipation, high shell strength and good durability, and is very popular with users. Moreover, many components of increased safety explosion-proof lamps, such as lamp sockets, interlock switches, etc., also use explosion-proof structures. Electrical equipment with flameproof enclosures is called flameproof electrical equipment. If an explosive gas mixture enters the flameproof enclosure and is ignited, the flameproof enclosure can withstand the explosion pressure of the explosive gas mixture inside and prevent the internal explosion from propagating to the explosive mixture around the enclosure. This is a gap explosion-proof principle, that is, a structure designed on the principle that the metal gap can prevent the spread of the explosion flame and cool the temperature of the explosion product, achieve flame extinguishing and cooling, and suppress the expansion of the explosion.

Types of explosion-proof lamps Explosion-proof lighting lamps: mainly used for lighting in flammable and explosive places, divided into explosion-proof fluorescent lamps, explosion-proof floodlights, explosion-proof floodlights, explosion-proof induction lamps, explosion-proof explosion-proof lamps, explosion-proof LEDs Lamps, explosion-proof platform lamps, explosion-proof street lamps and other explosion-proof emergency lamps: mainly used for emergency use in flammable and explosive places, divided into explosion-proof sign lamps, explosion-proof emergency lighting lamps and other explosion-proof signal lamps: mainly used in flammable and explosive places For command signals, it is divided into explosion-proof sound and light alarm lights, explosion-proof aviation signal lights and explosion-proof anti-corrosion lamps: mainly used in flammable, explosive and corrosive places: divided into increased safety explosion-proof anti-corrosion lamps, stainless steel explosion-proof anti-corrosion lamps, etc.
