The relationship between explosion-proof explosion-proof lamps and temperature:
1. Temperature measurement. The test point of the highest surface temperature of the explosion-proof explosion-proof luminaire is on the outer surface of the luminaire. Increased safety explosion-proof luminaires require that the maximum surface temperature of any part of the luminaire should not exceed the corresponding temperature group. The highest surface temperature of the luminaire appears on the blister of the light source. Therefore, the temperature group of the safety-enhanced luminaires of the explosion-proof luminaires using the same light source (due to the different test points, one external measurement, one internal measurement) is at least one or two groups. By determining the temperature-increased explosion-proof luminaires in this way, there is no high temperature that can ignite the explosive mixture.
Structural features of explosion-proof explosion-proof lamps:
2. The lamp holder adopts a structure with an explosion chamber. The portion of the screw socket where sparks may be generated when replacing the lamp should be placed in a separate explosion chamber. In order to prevent the spiral bulb from loosening itself in the lamp holder, the rotation torque and the screwing torque of the lamp holder should meet the requirements of the standard. The pin and base of the single-pin, non-starter fluorescent lamp shall comply with the provisions of the Fa6 lamp holder, and the structure is also a flameproof structure. This structure avoids the generation of sparks.

3. Components such as switches, triggers, etc. that may generate sparks or dangerous temperatures should be placed in an explosion-proof chamber or placed in a housing that achieves the same level of safety (eg, encapsulation, sanding, etc.) to avoid igniting flammable gases.
Explosion-proof explosion-proof light source option:
4. The choice of light source. Compared with other types of explosion-proof lamps, the increased safety type of explosion-proof lamps is the most stringent. The light source allowed by the feeder-powered luminaire is:
A. Fluorescent lamp without single starter with single pin;
B, general purpose incandescent lamps;
C, mixed light (self-ballasted mercury lamp).
