Then, explosion-proof treatment is carried out. Explosion-proof treatment mainly includes two aspects: explosion-proof coating and explosion-proof device.

The explosion-proof coating is to coat a special explosion-proof coating at the bottom of the street lamp, which can effectively isolate external sparks and gases and prevent the occurrence of **. Explosion-proof device refers to the installation of some special devices at the bottom of the street lamp, such as explosion-proof valves, explosion-proof covers, etc., which can quickly release the internal pressure and reduce the power of the street lamp.

Finally, strict testing and acceptance are carried out. After the explosion-proof treatment at the bottom of the street lamp is completed, strict testing and acceptance are required to ensure that the effect of the explosion-proof treatment meets the relevant standards and requirements. The inspection and acceptance mainly include visual inspection, sealing performance test, electrical performance test, etc., to ensure that the explosion-proof treatment at the bottom of the street lamp achieves the expected effect.

To sum up, the explosion-proof treatment at the bottom of the street lamp is achieved through steps such as selecting suitable materials, carrying out explosion-proof design, carrying out explosion-proof treatment, and conducting strict testing and acceptance. These measures can effectively prevent accidents during the use of street lamps and ensure the safety of pedestrians and vehicles.

4. One end of the prepared three-core power cable is introduced into the ballast cavity through the introduction device of the ballast input port, and then the L wire (live wire), N wire (middle line) and ground wire are respectively connected to the terminal of the number position of the ballast, and the hold-down nut is tightened.

5. Close the ballast box cover and tighten the fastening bolts, and finally connect the other end of the three-core cable to the 220V power supply according to the explosion-proof requirements.

6. When replacing the bulb, first cut off the power supply, check whether the chain is hung well, and then use an Allen wrench to unscrew the six hexagon bolts on the lamp shell, carefully pull the lamp body part downward, separate the lamp body from the lamp head shell, and unscrew the old bulb and replace it with a new bulb.

1. Explosion-proof street lamps are mostly installed outdoors, so it is very important when choosing explosion-proof street lights.

2. The protection level must reach (IP) 54 or above, anti-corrosion level (WF) 1 or above, and insulation and other level 1.

3. Finally, a grounding wire needs to be connected to the grounding terminal outside the ballast.

4. The scope of use of metal halide lamps and sodium lamps with explosion-proof street lamps, the light emitted by metal halide lamps is generally white light and is mostly used in areas with less fog, while the light emitted by high-pressure sodium lamps is yellow light and is mostly used in foggy urban areas, and the penetration of yellow light to fog is relatively strong.

1. When installing and maintaining the lamps, the power supply must be cut off.

2. When using, there is a certain temperature rise on the surface of the lamp, which is a normal phenomenon, and the center temperature of the transparent parts is high, so it should not be touched.

3. The ballast equipped by the company must be used.

4. The starting current of the lamp is times of the normal working current, and the starting current of the 250W lamp is the buried surplus.

5. The lamp head shell is equipped with a shock-absorbing foam stove roller, which must be taken out when it is installed and used for the first time.

6. Determine the installation position of the lamp according to the on-site environment and lighting needs, and prepare the corresponding length of three-core cable according to the distance from the lamp to the 220V power supply.

7. Pass the 2-meter three-core cable equipped with the lamp through the steel pipe and fix the lamp.

8. Open the fixing screw of the upper cover of the ballast box, loosen the compression nut of the cable introduction of the ballast box, and introduce the lamp cable and the power supply cable into the ballast box through the compression nut respectively.

9. According to the wiring diagram in the box, connect the lamps and power supply inlet cables, close the upper cover of the liquid ballast box, and tighten the screws. Then input the ballast box to the other end of the cable, and turn on the 220V power supply according to the explosion-proof requirements to illuminate.

10. When replacing the bulb, you only need to rotate the lamp shell in the clockwise direction to separate the lamp shell from the upper cover, remove the bulb, replace it with a new bulb, and install the lamp in the opposite direction.

Warning: 1. It is strictly forbidden to turn on the lamps with electricity.

2. When installing the lamp, be sure to ground the lamp shell and make it firm.
