Explosion-proof lamps and lanterns installation specification

1. Explosion-proof symbols, shell protection level and temperature group adaptability: explosion-proof symbols, shell protection level and temperature group of lamps and lanterns should be adapted to the explosion-hazardous environment. When the design does not require, the type of lamps and lanterns and explosion-proof structure of the selection should be in line with the provisions.

2. The use of lamps and lanterns fittings: lamps and lanterns fittings must be complete, shall not use non-explosion-proof parts instead of explosion-proof fittings, such as metal grille, lampshade, junction box and so on.

3. Selection of installation location: the installation location of the lamps and lanterns should be away from the release source, and do not install lamps and lanterns on and below the pressure relief ports and discharge ports of various pipelines.    

4. Fixed installation requirements: lamps and switches installed firmly and reliably, lamps and switches and junction box threads engage the number of buttons not less than 5 buckles, threads smooth, intact, no corrosion, and in the threads are coated with electric power composite grease or conductive rust-resistant grease switch mounting position should be easy to operate, the height from the ground is not less than 1.3 meters.

5. Shell integrity: the shell of the lamps and switches is complete, no damage or depression, groove, no cracks in the lampshade, no twisting and deformation of the metal grille, and the explosion-proof mark is clear.

6. The state of fastening bolts and sealing washers: the fastening bolts of lamps and switches have no looseness or corrosion, and the sealing washers are intact.

7. conduit and lamps, junction box connection: conduit and explosion-proof lamps, junction box connection should be tight, sealing intact; threads should be engaged in the number of buttons not less than 5 buckles, and should be coated with electric power composite ester or conductive antirust ester on the threads.

8. Adjustment of tilted installation: When the lamps are installed at an angle, the relative positions of the joints and steel tubes must be adjusted to ensure that the shading plate is directly above the bulb.

9. Installation and maintenance of safety measures: installation and maintenance of lamps and lanterns, you must first cut off the power supply; use, the surface of the lamps and lanterns have a certain degree of temperature rise is a normal phenomenon, the center of the transparent parts of the temperature is higher, do not touch.

10. Requirements for replacement of light bulbs: when replacing light bulbs, the same type and power of light bulbs should be used; if the type or power of light bulbs is changed, the matching ballast should be replaced accordingly.
