How to use the explosion-proof distribution box

With the rapid development of industries such as petroleum, chemical industry, military industry, engineering, factories, mines, and mining, explosion-proof distribution boxes are used more and more widely in production, storage, and rescue. How to prevent accidental explosion of the explosion-proof distribution box has become a very important issue in explosive gas hazardous locations. Since the explosion-proof distribution boxes inevitably generate sparks during their work, once they meet the explosive gas mixture at the production or rescue site, it will lead to an explosion accident, which will directly endanger the lives of national property and citizens. Therefore, as the most widely used lighting fixture, its explosion-proof technology has long attracted people's attention and great attention.

Explosion-proof distribution box is divided into: explosion-proof lighting box, explosion-proof power box, explosion-proof control box, explosion-proof control cabinet, explosion-proof power distribution cabinet, explosion-proof operation box, explosion-proof box, explosion-proof starting box, explosion-proof motor starter, explosion-proof soft start, explosion-proof frequency conversion Box, explosion-proof star triangle starting box, explosion-proof auto-coupling step-down starting box, explosion-proof magnetic starting box, explosion-proof power socket box, mobile explosion-proof box, BMG explosion-proof distribution box.

1, according to the actual lighting needs of the work site, determine the lamp installation location and method, and then press the lamp to the 220V power contact point to prepare the appropriate length of the three-core cable (if using the steel cable wiring will be introduced to the three-core cable Lamp installation place).

2, first remove the fixing screws on the wiring chamber, pull out the wiring part of the terminal box; take out the sealing ring and the connector (with set screw) from the packing box, insert the cables in turn; then separate the three-core cable end In the access box, mark “L” and “N” and the grounding point, press the cable with the pressure wire clamp, and fix it with the fastening screw, then tighten the joint, press the seal ring tightly, and tighten the set screw from the side.

3. Screw the part of step 2 into the steel tube, tighten the set screws from the side, and then install the lamp body along the guide rail of the junction box, then tighten the screws on the panel.

4. Finally, connect the other end of the three-core cable to the 220V power supply in accordance with the requirements of the explosion-proof distribution box.

5, when replacing the bulb, first cut off the power, then use the Allen wrench to remove the set screws on the shell, use a large screwdriver or other tools to loosen the lamp cover 6 turns, and then carefully remove the lamp cover by hand, rotating Replace the old bulb with a new one.
