The selection of explosion-proof lighting fixtures for explosion-hazardous locations should be based on the category and regional classification of the explosion hazard location and the level and group of explosive mixtures present in the establishment.
The lighting fixtures used in Zone 1.0 are specifically designed for lighting fixtures in Zone 0 and are currently still blank in China. Now we are developing special explosion-proof flashlights with light source cavity filling and battery cavity-based safety lines. The explosion-proof principle is to prevent the flashlight from being accidentally impacted, collided and dropped, and the light source cavity and the bulb blister are damaged at the same time. The oil in the cavity of the light source is rapidly cooled to cool the hot tungsten wire so as to achieve explosion-proof effect. In foreign countries, there is an explosion-proof light pipe lighting equipment specifically for the 0 zone, the explosion-proof lighting fixtures outside the 0 zone Yang, with the light guide the explosion-proof lighting into the zero zone location.
Explosion-proof lamps suitable for use in Zone 2.1 shall be flameproof, increased-safety, positive-pressure type, and composite-type explosion-proof lamps designed for use in Zone 1. In China's current explosion-proof regulations, some increase safety-type explosion-proof lamps are classified as suitable for use only in Zone 2. This is mainly due to the higher safety requirements for maintenance and maintenance, and the poor maintenance of China's factories and mines. Prepared.
Explosion-protected luminaires suitable for use in Zone 3.2 In Zone 2, in addition to the explosion-proof luminaires used in Zone 0 and Zone 1, there are also non-sparkproof explosion-proof luminaires designed specifically for Zone 2. In explosion hazardous locations, the vast majority of the area can be divided into 2 areas. Area 2 has a large area, good air circulation, and the accumulation of dangerous gases has a relatively low probability of explosion. The use of high-intensity gas discharge lamps as light sources abroad The spark-free luminaires have been widely adopted.
4.10 Dust explosion-proof lamps suitable for use in zone 10 Dust explosion-proof lamps with dust-tight enclosures must be used in Zone 10.
Dust explosion-proof lamps and lanterns suitable for use in zone 5.1l Dust explosion-proof lamps with dust-tight enclosures can be used in zone 11. Dust explosion proof enclosures with dust-proof enclosures are permitted in dust-explosive hazardous locations where there is only a combustible non-conductive dust mixture. Lamps.
