LED explosion-proof lamp installation route analysis

LED explosion-proof lamp 150w adopts unique heat dissipation structure, and uses heat transfer and heat conduction to accelerate heat conduction, effectively ensuring efficient heat dissipation of LED, so that LED life can reach 100,000 hours. The light distribution of the luminaire is unique, the illumination range is uniform, and the illumination angle is up to 220 degrees. The light is fully utilized; the light is soft and glare-free, which will not cause eye fatigue of the operator and improve work efficiency. Led explosion-proof lamp for use in the explosion-proof lamp of the winery: should use the zone road seal design; explosion-proof intrinsic safety type; protection grade IP65, anti-corrosion grade WF1, to achieve waterproof, dustproof, explosion-proof. The light source adopts the world's Zui bright LED, and the power consumption is only 40% of the metal halide lamp.

First, the LED explosion-proof lamp 150w line description and use matters

1, location selection

Electrical wiring should be routed where the risk of explosion is small or remote from the source of release.

2, laying method selection

The electrical lines in the explosion hazardous environment mainly include explosion-proof steel pipe wiring and cable wiring.

3, isolation seal

Non-combustible materials should be tightly blocked when laying the electrical circuit's channel and protecting the pipe, cable or steel pipe through the partition or floor between areas with different levels of explosion hazardous environment.

4, wire material selection

In the area of ​​explosion hazardous environment hazard level 1, the distribution line shall be copper conductor or cable. In the case of severe vibration, a multi-strand copper core cable or a multi-strand copper core cable should be used. Aluminum core power cables shall not be used in coal mines.

In the range of explosion hazard environment hazard level 2, the power line shall adopt aluminum core wire or cable with a cross-sectional area of ​​4mm2 and above, and the lighting circuit may adopt a cross-sectional area of ​​2.5 mm2. And above aluminum wire or cable.

5, allow current carrying capacity

For the selection of insulated conductor sections and cable sections in Zone 1 and Zone 2, the allowable current carrying capacity of the conductor shall not be less than 1.25 times the rated current of the fuse and the set current of the long-delay overcurrent release of the circuit breaker. The allowable current carrying current to the branch of the low-voltage cage induction motor shall not be less than 1.25 times the rated current of the motor.

6, the connection of electrical lines

The intermediate connections of the electrical lines in Zones 1 and 2 must be in the vicinity of the explosion-proof junction box or splice box that is compatible with the hazardous environment. The explosion-proof junction box should be used in Zone 1, and the increased safety junction box can be used in Zone 2.

If the aluminum line cable or wire is used in the electrical circuit of Zone 2, it must be reliable for the correct installation and maintenance of the user.

Second, the use of LED explosion-proof lamp 150w

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

2. 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.

3. Regularly eliminate dust and dirt on the outer casing of the explosion-proof lamp, and 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. Check whether the transparent parts have been damaged by foreign objects, and whether the protection net is loose, desoldered or corroded. If it is, stop using it and repair and replace it in time.

5. 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.

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

7. If the light source is damaged, the lamp should be turned off in time to notify 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.

8. 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.
