What should I do if the explosion proof metal halide lamp and the floodlight are not lit

First, check if the headlight bulb is short-circuited. If the bulb is normal, check the fuse and control line switch.

Take a look: open the lampshade to see if the front end of the bulb and the whole bulb are black, if it is black, replace it immediately, if the bulb is still not lit, replace the trigger (most of the bulb and the flip-flop are burned out). When the sodium lamp is just turned on, if you see the bulb turning white or green, it means that the bulb is aging, which will cause periodic flickering and flickering, and needs to be replaced.

Second listening: Hearing the squeak sound, it is the discharge sound from the ballast to the lamp port, indicating that there is something wrong with this line, check whether the wire head and the lamp port are short-circuited, and whether the shrapnel in the lamp port is in good contact with the bulb contact. If the sodium lamp is not lit after troubleshooting, and there is a buzzing sound, it means that the domestic and imported sodium bulbs, triggers and ballasts are not compatible, and the same specifications will be on.

Three smells: judge whether the ballast is broken, if there is no obvious burnout traces, smell the ballast to see if there is a burnt smell, it means that the ballast is burned out and needs to be replaced.

There is electricity at the screw mouth of the electric tester, but the light is still not on, it is a problem, how to repair it?

There are several reasons why the lamps do not light up, the main reasons are as follows:

1: The bulb and lampholder are burned out, and the maintenance method is to replace the bulb and lampholder of the same model;

2. The trigger or capacitor is burned out, and the trigger or capacitor of the same model is replaced; It is best to open the entire electrical box to see if there are electrical devices burned out or the circuit burned out in the electrical box. (Also, the explosion-proof lamp you use is of poor quality, and it is normal for it to be broken).

Thank you, go back and I'll check the explosion-proof light circuit, which explosion-proof light is of better quality?

From the surface point of view, the surface of the explosion-proof lamps is smooth without sand holes, no depressions, sprayed yellow plastic according to the national standard, uniform and no leakage, with EX logo, small and smooth knots, pure transparent glass without bubbles and impurities. Screws on the lamps and.

The accessories are generally made of 201 stainless steel, the minimum pressure of the lamp shell is not less than 6mm, and the minimum glass thickness is not 8mm. It is best to check the explosion-proof certificate, and many companies in the same industry have explosion-proof certificates that are PS, and it is best to go to the relevant detection machine.

Construct to verify the authenticity of the explosion-proof certificate. Explosion-proof lamps, light sources and electrical appliances should be of good brands, and they should not contain cheap water goods.

Metal halide lamps and LED lamps are different light sources used in explosion-proof floodlights, which can be used. Now everyone has begun to choose the CCD297 explosion-proof floodlight with LED light source, mainly for energy saving, long life, and compact appearance.

It cannot be connected directly, which is the most obvious wrong connection in explosion-proof construction. The connection method is to use the explosion-proof cable entry device in the junction box to lead the cable out, and the cable entry device should choose the kind of tail threaded, and then the iron pipe is directly connected with the tail thread of the cable entry device. If your steel pipe is a straight steel pipe, then it will not be difficult to screw it, if your steel pipe has bends or corners, then it is generally necessary to have another union joint.

If your steel pipe is a grounding network, then the grounding wire of the metal halide lamp should be crossed to the steel pipe with a jumper.

Inspection: Damaged lamps, poor line contact, etc.

If the lamp is damaged, you can buy a lamp of the same model or a lamp with the same voltage, power and function to replace it.

Check to find that the part is broken.

The main susceptible metal halide lamps are bulbs, ballasts, and triggers.

Try changing the bulb first, then change the trigger if it doesn't light up, if it doesn't light up, it's the ballast.

Hello, can you ask how many watts and how much is the ZJD metal halide lamp Thank you.

The metal halide lamp and the rectifier are clearly protected by two shells, one is a rectifier and the other is a lamp, and the rectifier shell contains capacitors, and there is no indication that the capacitors cannot be discharged in China.

1. All the advantages are that the structure is compact, delicate and compact, and the installation and maintenance are relatively convenient. When the ballast fails, it is easy to remove the lamp head as a whole and replace it with a spare lamp head to restore the lighting immediately. Faulty lamp heads can be taken to a convenient place and slowly detected for repair.

In addition to the platform guardrail installation, the double inlet structure is generally made, and there is no need for another junction box.

A rectifier is a device that converts alternating current into direct current, which can be used for power supply devices and radio signal detection. Rectifiers can be made of vacuum tubes, ignition tubes, solid-state silicon semiconductor diodes, mercury arcs, etc. On the other hand, a device that converts direct current into alternating current is called an "inverter".

In the standby UPS, only the battery needs to be charged, and there is no need to supply power to the load, so there is only a charger. In a double-conversion UPS, this device not only supplies power to the inverter, but also charges the battery, so it is called a rectifier charger.

A rectifier is a rectifier device, which is simply a device that converts alternating current (AC) to direct current (DC). It has two main functions: first, it converts alternating current (AC) into direct current (DC), which is filtered to supply the load or to the inverter; Second, the battery is charged at a voltage that is charged.

Therefore, it also acts as a charger.

Metal halide lamps are not the same thing as mercury lamps at all! At present, mercury lamps are rarely used in new projects in China, mainly considering energy saving and light efficiency. Most of the chemical plants and workshops are mainly lit by metal halide lamps.

Metal halide lamps are a type of high-intensity gas discharge lamps (HID). At present, this light source (light bulb) must be used with a separate ballast. I haven't heard of anyone who can make a high-intensity gas discharge light source for the self-balancing type.

Your question should be: the difference between the two types of explosion-proof metal halide lamps in one piece and split type.

All-in-one: The ballast is built into the lamp head, which is generally an imported brand. The advantage is that the structure is compact and delicate, and the installation and maintenance are relatively convenient.

When the ballast fails, it is easy to remove the lamp head as a whole and replace it with a spare lamp head to restore the lighting immediately. Faulty lamp heads can be taken to a convenient place and slowly detected for repair. In addition to the platform guardrail installation, the double inlet structure is generally made, and there is no need for another junction box.

The disadvantage is that it is slightly higher.

Split: The ballast is placed in a separate flameproof electrical box, which is generally a domestic brand product. The advantage is that the cost is low. The disadvantage is that it is large in size and inconvenient to install. When the ballast fails, the ballast can only be replaced on site, and the repair time is relatively long.

Don't quite understand your question about the ballast device of explosion-proof metal halide lamp? The ballasts of explosion-proof metal halide lamps are the same as other ballasts. He's explosion-proof, explosion-proof, it's actually just on top of the lamp, which is the shell.

There is a kind of outside the town (with ballast): that is, you take a mercury lamp and connect it to the ballast (mercury lamp with ballast).

There is also the self-town (with ballast): that is, there is already a ballast in the lamp head of the mercury lamp, so don't connect it, directly connect it to the lamp head, and it will light up, this is the self-town.

I don't know what kind of light source your floodlight is? With such a large power, it should be a metal halide lamp, whether it is the reason for the ballast, it is recommended to let the manufacturer test it. Our company is also a manufacturer specializing in the production of metal halide floodlights, generally this kind of lamps and lanterns have a warranty period, my company name is:
