Explosion-proof t8led lamp grille lamp petrochemical plant-Lant Lighting

  There are many petrochemical plants. When considering lighting, explosion-proof led lamps are required to improve safety. At present, Shenzhen Langte Lighting led explosion-proof lamps have explosion-proof t8led lamps and explosion-proof t5led lamps for you to choose from.

1. The explosion-proof t8led lamp is composed of two parts

Explosion proof enclosures and fluorescent tubes

Therefore, the price of explosion-proof lamps consists of two parts. The price of explosion-proof lamp shells generally requires high structural requirements, which is higher than that of fluorescent lamps. The price of T8led lamps is higher than that of fluorescent lamps. Therefore, in general, the price of explosion-proof LED lamps is higher than that of fluorescent lamps. Ordinary explosion-proof lamp. But the safety is greatly improved.

Second, the price picture of explosion-proof led lamp

 The explosion-proof structure type of the explosion-proof lamp should be determined according to the regional level and scope of the explosive gas environment.

 For example, explosion-proof lamps must be used within the scope of Zone 1;

  Fixed lamps and lanterns in Zone 2 can adopt explosion-proof and increased safety type, and mobile lamps must adopt explosion-proof type. The level or group of the selected explosion-proof lamp should not be lower than the level and group of the explosive mixture in the explosion-hazardous environment. At the same time, the influence of the environment on the explosion-proof lamp should be considered, and it should meet the requirements of various environments such as ambient temperature, air humidity, corrosive or polluting substances.

Explosion-proof lamps and lanterns must be installed in explosion-proof enclosures, and explosion-proof boxes are required for circuits, wiring heads, switches, etc.

Three, explosion-proof led lamp wiring diagram

1. Installation of single-tube explosion-proof lamp:

1. Determine the installation position of the lamp, select the appropriate installation method, and prepare the corresponding length of φ6~8mm three-core cable according to the distance from the lamp to the 220V power supply contact;

2. Open the two locks on the lamp holder to open the back cover, pass one end of the prepared three-core cable through the inlet, connect the live wire (L) to the "L" terminal, and connect the neutral wire (N) to the On the "N" terminal, connect the ground wire (PE) to the "PE" terminal, and then press the cable at the inlet with a compression nut, close the back cover, fasten the lock, and then connect the three-core cable The other end is connected to the power supply, and the lighting can be realized.

2. Wiring diagram of double tube led explosion-proof lamp

The plugs at both ends are connected in parallel, and the input line can be used through the junction box. Because there is a power supply inside the LED tube. No ballast required. For example, the explosion-proof lamp shell equipped by Langte Lighting has actually been equipped with the internal circuit. Can be used directly.

The difference between explosion-proof led lamps and ordinary led lamps

1. Different models: ordinary lamps can be generally divided into fixed, removable and embedded, etc. The model of explosion-proof lamp represents a kind of explosion-proof technology, explosion-proof principle and explosion-proof structure. Different explosion-proof models have corresponding standard requirements.

2. Different standards: Explosion-proof lamps are made in strict accordance with national standards. The shell of explosion-proof lamps will be marked with Ex explosion-proof type, explosion-proof grade and temperature group and other explosion-proof marks. Ordinary lamps do not have such strict explosion-proof grades. and type tags.

3. Different functions: most of the explosion lamps are LED lamps, which have the advantages of high electro-optical conversion rate, low heat dissipation, low power consumption and long service life. The explosion-proof lamp has a good explosion-proof function and is used for lighting in more dangerous places. Explosion-proof lamps can prevent the generation of arcs, sparks and high temperatures inside the lamps, while ordinary lamps are prone to sparks and heat on the surface of the lamp during lighting. If they come into contact with explosive gases, they will lead to explosions.

4. Different installations: Generally speaking, electrical appliances with explosion-proof function cannot be grounded, otherwise it is easy to generate sparks. Most of the power cords used are also explosion-proof and flame-retardant, and the protection against electric shock is also to prevent explosion-proof lamp shells and some parts. Electricity can cause electric shock or spark explosion.

5. Different quality: The production process and materials used are different, and the explosion-proof lamp has advantages and performance that cannot be surpassed and compared by ordinary lamps.

6. Different energy saving: Explosion-proof lamps have the characteristics of high efficiency and energy saving, which can save more than half of electricity compared with ordinary lamps, and the replacement of explosion-proof lamps is also very convenient, as long as the end cover is removed, it can be replaced directly.

Recommended, explosion-proof grille light, Langte Lighting provides explosion-proof grille lamp panel, replaces the LED lamp, becomes the explosion-proof grille lamp with a specification of 600*600, and adds explosion-proof mesh, which has reached the convenience requirements.
