For a long time, power plant lighting system safety hazards commonly exist in the safe operation system of each thermal power plant, due to the harsh site environment, long lighting time, high lighting requirements, a huge number of lamps and lanterns, inconvenient maintenance, and other issues have long plagued the relevant management, operation, and maintenance personnel.
Especially in the worst environment in the power plant coal transmission system, most of the lamps and lanterns due to backward design, resulting in too many lamps and lanterns on site, unreasonable lighting installation position, and illumination can not meet the normal production and maintenance requirements, greatly increasing the late maintenance costs, not only resulting in a waste of resources but also greatly reduce the efficiency, coupled with the plant high temperature, dust, vibration, corrosion of the special working environment, lighting can not meet the basic Safety production needs
The overall site environment is relatively poor, with uneven illumination, most of the highest illumination is only about 20Lx, seriously affecting the production and normal maintenance of workshop equipment and maintenance, especially the bridge part of the lighting, illumination is insufficient, the ground is slippery, more steps, walking between people have a dizzy feeling, lurking huge security risks, for these situations we developed the corresponding lighting products, while the development of the corresponding Lighting solutions.
First of all, our lamps and lanterns fully meet and higher than the GB3836 standard requirements, to ensure that the lamps and lanterns are explosion-proof and reliable, the product light source module, uses a high-brightness LED light source, with a rate of constant current drive power supply, than the gas discharge lamp power saving up to 60%;
LED components are all sealed, waterproof, and dustproof, with no internal cleaning and maintenance; the circuit substrate has low thermal resistance, and a specially designed module circuit, and each unit failure will not affect the rest of the normal operation of the remaining components.
Secondly, for the power module, we use a constant current drive power supply with an intelligent power regulator; with a luminous flux compensation function, reducing light decay, to ensure the luminous efficiency of the LED light source;
With over-voltage protection, over-current protection, and surge current protection functions.
Finally, the heat dissipation module, explosion-proof lamp shell using aluminum alloy high-pressure casting molding, the surface after shot-blasting high-pressure electrostatic spraying, effectively provides the heat dissipation performance of the shell;
Aluminum substrate close to the aluminum alloy shell, can instantly convert the point heat source into a surface heat source, heat dissipation area multiplied, conducive to rapid heat dispersion, improve the efficiency of heat dissipation;
Shell surface with shunt dispersion groove, with the help of airflow to take away heat; heat sink high density The heat sink has a high density, which greatly provides heat dissipation area and fully guarantees the heat dissipation requirements of LEDs and longer service life.
We recommend the following special explosion-proof lamps for power plant grid lighting scenarios.
