Explosion-proof lights and lampshades should be able to automatically cut off the power before they are opened. However, due to the complexity of setting up the interlocking device, it is difficult to implement. Therefore, most lamps and lanterns only have warning signs such as “No live-on†on the obvious part of the enclosure. Because the surface temperature of the bulb is still high after power off, if you open the lampshade immediately, there is still the danger of igniting the explosive gas mixture (mainly flameproof structure). Therefore, the surface temperature of the incandescent lamp, high pressure mercury lamp, and high pressure sodium lamp are high. , but also quickly open the lid of the luminaire to pay attention to this. The use of more CeY-1 explosion-proof fluorescent lamps by the company's unit has an interlock mechanism that opens and closes the power supply, providing convenience and safety for maintenance work. Because the fluorescent lamp is a cold light source lamp, there is no surface high temperature, and the lid can be opened immediately after the power is turned off.
When replacing the bulb (tube), the explosion-proof lamp 's flameproof joint shall be properly protected and shall not be damaged; the cleaned explosion-proof surface shall be coated with phosphated plaster or 204-1 anti-rust oil; other paints shall be prohibited from painting; There shall be no rust layer on the surface. If there is slight rust, there should be no numbness after cleaning. The seals used for dust protection and waterproofing must be kept intact. This is very important for the increased safety lighting. If the seal is seriously damaged, replace it with a seal of the same size and material and replace the entire light if necessary. When overhauling, pay attention to whether the lampshade is intact and replace it immediately if it is broken.
Portable luminaires are divided into two types: feed-grid-powered and self-powered. For lamps powered by the feed-in network, rubber-sleeved cables shall be used between the explosion-proof junction boxes (boxes) or explosion-proof plugs and the lamps. The grounding or connection of the neutral conductor shall be within the same sheath; the cable shall adopt the minimum allowable cross-section of the main conductor core. 25 mm2 YC, YCW heavy duty rubber cable. One point to be emphasized here: The cable for portable lighting does not allow intermediate connectors. The author's unit has had such an accident: One night repairing the ethylene transfer pump, then the temporary explosion-proof lamp, the explosion-proof mark is dIICT4. When the fitter took up the lamp and looked closely at the pump body, it ignited the ethylene gas leaking from the pump body and burned one of its faces. After checking the explosion-proof performance of the lamp is normal, the problem lies in the lamp's cable. Originally, there was a cable joint 15m away from the lamp, which was wrapped with an insulating wrap. When the cable was connected to the lamp, it was dragged on the ground to expose the cable core. When the fitter raised the lamp to illuminate the pump body, the bare wire core hit the equipment base channel steel. On the ground, ignited the ground and ignited the ethylene gas mixture. This accident exposed the loopholes in our explosion-proof safety management. After the accident, we conducted a thorough inspection of all portable lamps and their cables to eliminate the hidden dangers of similar accidents. This accident tells us that in the management of explosion-proof electrical safety, there must be no luck mentality. We must do it in strict accordance with relevant regulations and requirements in order to be foolproof.
