I would like to ask if the metal shells of electrical equipment (fans, explosion-proof lights, etc.) in Class IIB explosion-proof places must be grounded both inside and outside? The equipment (inner cavity) has been connected to the ground grid outside the explosion-proof area through a dedicated grounding wire (combined with the phase wire and grounding wire in a steel pipe). Should a grounding wire be installed in the explosion-proof area to ground the equipment shell? If necessary, how should the grounding wire in the explosion-proof field be protected to prevent static sparks? In addition, the fan manual indicates that both the inside and outside of the casing should be grounded.
On the original construction drawing, the wiring from the distribution box to the explosion-proof lamps and explosion-proof sockets uses B-plastic copper wires to pass through the bridge, and then passes through galvanized steel pipes after exiting the bridge to lay them to the explosion-proof lamps and explosion-proof sockets. But now some people have proposed that the wiring through a section of the bridge should not use B lines, but should use cables. Is there any regulation in the regulations that this person mentioned? I am a newbie, I hope you can give me some answers, wait online!
Whether to use cables depends on whether the environment of the bridge section is in an explosion hazardous environment. If it is based on the design specifications for electrical installations in explosion and fire hazardous environments, cables should definitely be used. , otherwise you can use line B. The general practice is to use flame retardant cables. I have seen many examples of laying B wires through pipes on the bridge, but it is not appropriate to directly lay B wires on the bridge! Most explosion-proof lights are waterproof and anti-corrosion. It mainly depends on your choice. Just choose the outdoor explosion-proof type.
Can explosion-proof lights be installed outdoors and exposed to the sun and rain? Explosion-proof lamps are mainly used in dust, combustible gas, and flammable warehouses. Explosion-proof is mainly sealed, including the explosion-proof flexible connecting pipe and junction box, which have sealing gaskets. However, they are not moisture-proof lamps. Moisture-proof lamps The appearance is different from that of explosion-proof lamps. It is recommended to use special outdoor waterproof and splash-proof lamps for outdoor use.
