Fluorescent light sources are widely used in a variety of locations as fluorescent light sources. Fluorescent lamps have the advantages of high luminous efficiency, good color rendering performance, long life, soft light, large light-emitting area of ​​lamps, small brightness, small glare, uniform distribution of luminous flux and low temperature rise. They are ideal light sources for chemical fiber enterprises. In the lighting design of the curtain fabric, in addition to the use of high-pressure mercury lamps in the places where the visual conditions are lower, and the high-quality mercury lamps and the general places requiring waterproof and dustproof lighting, the other main production sites are all illuminated by fluorescent lamps.
Current Fluorescent Lamp Usage Since the fluorescent lamp is a gas discharge lamp that has a negative volt-ampere characteristic during operation, the ballast is connected in series to limit the current through the lamp and enable the lamp to start and operate normally. . Therefore, the ballast is an indispensable important component of fluorescent lamps, and its performance is directly related to the lighting effect of fluorescent lamps.
At present, in industrial and mining enterprises and civil buildings, low-efficiency fluorescent lamps are commonly used with corresponding starters and magnetic ballasts for illumination. The inductor ballast fluorescent lamp has the following disadvantages: low luminous efficiency, high power consumption, easy blackening of the lamp tube, short life, easy to break the starter, frequent replacement, low voltage cannot be started, and the ballast is heated at high voltage. It is easy to cause fire, burn out the lamp tube, easy to produce noise, the light is easy to flash, and the electrical maintenance work is large. In large-scale production sites, especially chemical fiber plants with high illumination requirements and large plant area, such as the nylon plant of Yueyang Petrochemical Plant and the spinning workshop of polyester plant, use this kind of inductance ballast fluorescent lamp, due to the starter and the lamp Easy to destroy, maintenance can not keep up, resulting in poor lighting effect, uneven illumination, forming dark areas, have a great impact on the quality of spinning products, production efficiency and vision health, while lighting maintenance costs are high, so shop operators And the electrician reacted strongly to this, hoping to replace the ideal fluorescent lamp to improve the lighting conditions and reduce the lighting maintenance workload.
With the increasing attention of the country to lighting energy conservation and the many defects of magnetic ballasts of magnetic ballasts, in the late 1980s, ordinary electronic ballasts were introduced in China. There is no qualitative difference between the working principle and function of the electronic ballast and the magnetic ballast, except that the former operates in the frequency range of 20 to 100 KHz, while the latter operates in the 50 Hz power frequency. In fact, the electronic ballast is composed of an electronic frequency converter plus a high-frequency ballast. Due to the increase of the working frequency, its own power consumption, volume and weight are greatly reduced compared with the power frequency ballast, and it is not necessary to adopt The starter shortens the start-up time. It should be said that the birth of ordinary electronic ballasts is a big improvement. Compared with magnetic ballasts, it has the advantages of power saving, small size, light weight and easy start, but there are also low power factor (about 0.6). ); the harmonic component is large (more than 130% of the fundamental wave), the third harmonic is serious (up to 90% of the fundamental wave), causing distortion of the grid voltage waveform, polluting the grid, affecting the normal operation of other electrical equipment; lack of necessary Protection, work is not reliable, the lamp is easy to damage; there is no soft start measures, so that the two ends of the lamp are blackened in advance, the life is shortened and other defects, plus some manufacturers' components are inferior and shoddy, resulting in repeated failures in use. It has caused a lot of accidents, making people daunting about the new product of electronic ballasts. Most of the current electronic ballasts distributed in the city are still such ordinary electronic ballasts.
Energy-saving electronic ballast performance and characteristics Energy-saving electronic ballast overcomes many defects of common electronic ballasts, passive filter to achieve power factor of 0.9 or more, power saving effect is more significant, harmonic total drop Up to 30%, the third harmonic dropped to 18%, combined with soft start, abnormal state protection and other measures, its performance has been greatly improved, and reliability has been greatly improved. This electronic ballast is used with high-efficiency small-diameter fluorescent tubes and new lamp holders, and has received good lighting effects and has been well received by users. Due to the difference in the technical level and manufacturing process of each factory, the performance of the energy-saving electronic ballasts produced is also different, and should be selected for use. The energy-saving electronic ballast fluorescent lamps used in the curtain fabric project are provided by two lamps and lanterns factories. The technical performance and characteristics of the DW-36 fluorescent lamps provided by Changsha Huaxing Automatic Control Equipment Factory are described below.
The use of energy-saving electronic ballast fluorescent lamps in the curtain fabric project With the rapid development of China's national economy, the illuminance standards are also correspondingly improved, enabling workers to work under good lighting conditions. According to international surveys, after the improvement of factory lighting conditions, labor productivity can be increased by 2 to 10%, transportation accidents can be reduced by 5 to 10%, consumption can be reduced by 4 to 8%, and product quality can be improved by 10 to 20%.
High-mast lights are quite different in nature from more typical street or roadway lights. High-mast fixtures are regularly mounted at 60 ft to more than 100 ft above ground level and occasionally as high as 250 ft. Normal Street Lights are typically mounted at heights lower than 60 ft, and many are in the 30-ft range.
The applications for high-mast lights include installations at transportation terminals, other large, outdoor maintenance or storage yards, and specialty roadway applications. The aforementioned freeway interchange installations are probably the most common roadway application, although you will find some high-mast lights within municipalities in busy areas
