III. Technical preparation methods for energy management of lighting power saving contract (1) The actual electric power of the three light sources is tested by “Hanghua” brand produced by Shanghai Xinhuali Electric Meter Factory and 2 single-phase electronic energy meters of 2.5A. Verified by the senior engineer of the company's electric energy meter verification room. The meter error is within 0.6%. The field test measures the power consumption (Kwh) of 24 hours a day, and then calculates the actual power consumption of the three light sources under the actual voltage state according to the power P=power consumption (Kwh) ÷ ignition time 24 hours.
(2) The actual ground illuminance value of the three light sources is tested by using a digital illuminometer (lux table) directly under the vertical direction of the three electric light sources, and directly reading the reading illuminance value Lx.
(III) Test of the actual color rendering performance of the three light sources The instrument for testing the color rendering performance is not portable and cannot be measured by the instrument in the field. Therefore, the comparison method is used to compare the scenes intuitively.
Its intuitive method is:
One is: first put your hands in the sun to watch the color, the hands are rosy and full of vitality.
The second is: then put the hands under three light sources to see the color, the color of the hands under the three light sources is very different.
The third is to compare the color of the hands under the three light sources with the color difference under the sunlight. The smaller the difference in color with sunlight, the higher the color rendering performance of the light source.
(4) Test of the actual stroboscopic effect of three kinds of light sources 1. Identification and evaluation tools: tools for visually identifying and evaluating the stroboscopic and stroboscopic effects of electric light sources, usually using gyro detection special gyro.
2, identification and evaluation criteria: identification and evaluation of electric light source stroboscopic and stroboscopic effects, is based on sunlight. The luminous flux of sunlight is smooth and stable, and there is no stroboscopic and stroboscopic effect.
The luminous flux of the electric light source is smooth and stable, and the closer to the sunlight, the smaller the stroboscopic depth of the electric light source, and the smaller the stroboscopic effect is.
3. Identification and evaluation methods:
A. First select a plane under the sun, and rotate the dedicated detection gyro on the plane. The special detection pattern on the gyro is a multi-channel black and white halo. In the whole process of rotation, the pattern on the gyro does not change with the speed of rotation, but is stably fixed.
This black and white, and stable fixed aura pattern, color phenomenon, indicates that the sun has no stroboscopic and stroboscopic effects.
B. Under the three light sources of mercury lamp, metal halide lamp and Qingdao flange energy-saving lamp, rotate the special detection gyro. The pattern under the three light sources is different. C. If it is directly below a certain light source, rotate the gyro. picture of. A plurality of auras with different colors are produced, and each aura will exhibit a random change in the direction of rotation, the speed of rotation, and the color as the speed of the rotation of the gyro changes. This rich pattern of patterns and colors indicates that the stroboscopic and stroboscopic effects of this source are very harmful.
D. If the pattern is rotated on the top of the gyro directly under a certain light source. Only a plurality of black and white halos are produced, and the black and white halo changes with the rotation speed of the gyroscope. Its rotation direction, rotation speed, and color do not change, and it is stable and fixed, which is similar to the effect under the sun. This indicates that this source has no stroboscopic and stroboscopic effects.
(V) Test of effective visual illumination of the ground and space The ground effective visual illumination and spatial effective visual illumination are the comprehensive feeling and evaluation of the human eye to the ground and space lighting effects and quality. It is related to the physical quantity such as luminous flux, light color, color rendering performance and stroboscopic effect in the lighting environment. It is also related to physiological factors such as human gender, age, and sensitivity of the human eye to red, green and blue light.
When the human eye perceives the stimulation of light, it cannot make a quantitative judgment on the intensity of light. However, it is very accurate to evaluate the light intensity of different types of light sources or several light sources of the same kind in the same space. Especially in the bright visual environment, this accuracy is quite high.
Therefore, to evaluate the ground effective visual illuminance and space effective visual illuminance of the three light sources, the following methods are adopted:
First, the Qingdao Franconian energy-saving lamps were used in the workshop to replace the original mercury lamps and the original metal halide lamps. Establish an actual lighting scene environment under three identical spatial conditions.
Secondly, the technicians involved in the technical preparation will experience, compare and evaluate the ground brightness and spatial brightness in the lighting environment of the three light sources.
The third is: You can also read the small number 6 Arabic numerals on the stock market in the evening newspaper in the lighting environment of the three light sources. Compare it to clarity and realism.
The fourth is: let the production workers in the production workshop feel and test the actual lighting effects and quality of the three light sources in the actual production operation.
(6) Three kinds of traditional light sources, such as mercury lamp and metal halide lamp, which are used for the actual ignition and ignition reliability of the three light sources. Jinniu Iron and Steel Co., Ltd. has been used for many years and has a good understanding of its ignition reliability. In the technical preparation of this case, the main purpose is to test the energy-saving lamps for the 6U-50W high-frequency contract energy management of Qingdao Frank, in the actual grid environment and space environment with severe voltage fluctuation, voltage drop, harmonic power and surge current. The reliability of igniting.
The technical method is: the Qingdao Franco 6U-50W high-frequency contract energy management special energy-saving lamp is installed in the production workshop and actually ignited for 6 months.

Fourth, the lighting energy-saving contract energy management technology preparation time <br> The technical preparation of this case, since mid-March 2006.

VII. Energy-saving and energy-saving contract after energy management implementation Energy-saving benefit evaluation (I) Saving electricity efficiency after reforming high-pressure mercury lamp (calculated by turning on the light every day for 24 hours)
1. After replacement, the electric power saved by 1 lamp = mercury lamp electric power 393W - energy saving lamp electric power 64W = 329W
2. After replacement, the electricity saved by 1 lamp for 1 day is turned on 24 hours per day = 329W × 24 hours = 7.796 degrees 3. After replacement, the electricity cost saved by 1 day for 1 day is 24 hours per day = 7.796 degrees × The comprehensive electricity price is 0.463 yuan / kWh = 3.66 yuan 4. After replacement, the electricity cost saved by 1 lamp for 1 month is 24 hours per day = 3.66 yuan per day × 30 days = 109.8 yuan 5. After replacement, 1 lamp saves 1 year The number of electricity charges is turned on 24 hours a day = 109.8 yuan per month × 12 months = 1317.6 yuan. 6. After the replacement, the original high-pressure mercury lamp used to maintain the cost of replacing the mercury lamp is saved by one lamp for one year. Due to its technical quality, Qihui's ignition life is about 2-3 months. In this case, the maximum life expectancy is 3 months. 1 year 1 lamp needs to be replaced = 12 months ÷ 3 months = 4盏. The market price of 400W mercury lamp is about 23-28 yuan. In this case, the minimum value of the price is 23 yuan. therefore,
1 lamp saves the cost of replacing the lamp for 1 year = 4盏×23 yuan=92 yuan 7. After the replacement, the total benefit of 1 lamp saving for one year is the contraction energy management after the original high-pressure mercury lamp is implemented. The value of the increase is 3 times higher than the original = 4 times of the original, and the lighting effect and quality are greatly improved.
1 lamp saves 1 year total benefit = 1 year saves electricity fee 1317.6 yuan + saves mercury lamp cost 92 yuan = 1409.6 yuan 8, after replacement, 1 lamp saves 3 years of total benefit to the original high pressure mercury lamp implementation of contract energy After the management of power saving transformation, the value of the ground illuminance is increased by 3 times compared with the original = 4 times of the original, and the lighting effect and quality are greatly improved.
The total benefit saved by 1 lamp for 3 years = the total benefit saved by the year is 1409.6 yuan × 3 = 4228.8 yuan (2) The power saving effect after the metal halide lamp is modified (calculated by turning on the lamp every day for 24 hours)
1. After replacement, the electric power saved by 1 lamp = metal halide lamp electric power 519W-energy-saving lamp electric power 64W=455W
2. After replacement, the electricity saved by 1 lamp for 1 day is turned on 24 hours per day = 455W × 24 hours = 10.92 degrees 3, after replacement, the electricity cost saved by 1 day for 1 day is 24 hours = 10.92 degrees × The comprehensive electricity price is 0.463 yuan / kWh = 5.06 yuan 4. After replacement, the electricity cost saved by 1 lamp for 1 month is 24 hours per day = 5.06 yuan per day × 30 days = 151.8 yuan 5. After replacement, 1 lamp saves 1 year The number of electricity charges is turned on 24 hours a day = 151.8 yuan per month × 12 months = 1821.6 yuan 6. After the replacement, 1 lamp is saved for 1 year. The original metal halide lamp used to maintain the replacement of the metal halide lamp Its ignition life is about 1 year, and 1 lamp needs to be replaced 1 year. The market price of 400W metal halide lamps is around 60-80 yuan. In this case, the minimum value of the price is 60 yuan. Therefore, 1 lamp saves the cost of replacing the lamp for 1 year = 1盏×60 yuan = 60 yuan. 7. After the replacement, the total benefit saved by 1 lamp for 1 year is implemented after the contract energy management of the original metal halide lamp is implemented. The increase in ground illuminance is 25% higher than the original, and the lighting effect and quality are significantly improved.
1 lamp saves 1 year total benefit = 1 year saves electricity 1821.6 yuan + saves mercury lamp cost 60 yuan = 1881.6 yuan 8, after replacement, 1 lamp saves 3 years of total benefit to the original metal halide lamp contract energy After the management of power-saving renovation, the increase in ground illumination is 25% higher than the original, and the lighting effect and quality are significantly improved.
The total benefit of 1 lamp saving for 3 years = 1 year saving total benefit 1881.6 yuan × 3 = 5644.8 yuan
