The explosion-proof lamp and lamp cover should be able to cut off the power automatically before opening. However, because the interlocking device is complicated and difficult to implement, most of the lamps only have a warning sign on the outer casing that is clearly prohibited from being powered on. Because the surface temperature is still high after the lamp is powered off, if the lamp cover is turned on immediately, there is still the danger of igniting the explosive gas mixture (mainly the explosion-proof structure), so the incandescent lamp, the high-pressure mercury lamp, the high-pressure sodium lamp, the light source with high surface temperature of the bulb. Pay attention to this when you can quickly open the cover.

However, if an explosion-proof fluorescent lamp is used, it has an interlocking mechanism for opening and closing the power, which provides convenience and safety for the maintenance work. Since the fluorescent lamp is a cold light source lamp, there is no high temperature on the surface, and the cover can be opened immediately after the power is turned off.

When replacing the bulb (tube), the explosion-proof joint surface of the explosion-proof lamp should be properly protected and must not be damaged; the cleaned explosion-proof surface should be coated with phosphate paste or 204-1 anti-rust oil, and it is strictly forbidden to paint other paint; There shall be no rust layer on the surface. If there is slight rust, there shall be no numbness after cleaning. Sealing rings for dustproof and waterproof must be guaranteed to be in good condition, which is very important for increased safety lamps. If the seal is damaged seriously, replace it with a seal of the same specification and the same material and replace the entire lamp if necessary. Pay attention to the integrity of the lamp cover during maintenance, and replace it if it is broken.

Explosion-proof luminaires should be regularly maintained and repaired in time.

1. Maintenance and maintenance personnel are required to undergo post training to understand the performance of the lamps and to clearly define the use requirements. Maintenance personnel must have the expertise to familiarize themselves with the structure of the lighting product.

2, check the plastic housing (transparent parts) of the lamp for serious discoloration, such as serious discoloration, indicating that the plastic has aged. Check whether the transparent part has been damaged by foreign matter, and whether the protection net is loose, desoldered, corroded, etc. If it is, stop using it and repair and replace it in time.

3. Regularly eliminate dust and dirt on the explosion-proof lamp housing to improve the light efficiency and heat dissipation performance of the lamp. The cleaning method can be sprayed according to the protective ability of the lamp housing (above the sign on the lamp) or with a damp cloth. When cleaning with water spray, the power should be cut off. It is strictly forbidden to wipe the plastic housing (transparent part) of the lamp with a dry cloth to prevent static electricity.

4. If the light source is damaged, the lamp should be turned off in time to inform the replacement, so as to prevent the electrical components such as the ballast from being abnormal for a long time because the light source cannot be started.

5. After opening the cover, check whether the flameproof joint surface is intact, whether the rubber seal is hard or sticky, whether the wire insulation layer is green and carbonized, and whether the insulation and electrical components have deformation and scorch marks. If these problems are found, they should be repaired and replaced in time.

6. When opening the lampshade, follow the warning card requirements and open the cover after disconnecting the power supply.

7. If there is accumulated water in the lamp cavity of the lamp used in the humid environment, it should be removed in time, and the sealing parts should be replaced to ensure the protective performance of the casing.

8. The sealed part of the lamp should not be removed and opened frequently.

9. Apply a damp cloth (not excessively wet) before closing the cover to lightly return the light and transparent parts to improve the light efficiency of the lamp. A layer of 204-1 replacement rust preventive oil should be applied thinly on the flameproof joint surface. When closing the cover, it should be noted that the seal ring is sealed at the original position.

10. The model, specification, size and performance of the light source, components and electrical components after repair and replacement shall be identical to the light source, components and electrical components before the repair and replacement.
