Recently, Qingdao Unicom began to renovate the lighting of 16 end station measuring stations, replacing the original electronic ballast type fluorescent lamps with LED lighting lights, and replacing some of the aging lighting lines. After calculation, the power saving rate reached 75. %, can save more than 200,000 degrees of electricity in years.
At present, the lighting fixtures of the 16 end stations of Qingdao Unicom use 40W single and double-tube electronic ballast type fluorescent lamps, all of which are 24-hour lighting. This mode of operation wastes power and easily causes safety accidents (ballast type). Fluorescent lamps are prone to spontaneous combustion of lamps, causing fire accidents). In order to complete the energy-saving emission reduction targets and eliminate safety hazards, the company decided to modify the lighting of all end-office measuring stations. They first investigated it and developed a retrofit plan. They decided to replace the fluorescent lamp of the measuring platform with a long-life, energy-efficient LED lamp (power of 18W) and replace the aging lighting circuit to save energy and eliminate safety. The purpose of the hidden danger. In order to check the effect, they selected the Shandong Road Surveying Station as a pilot project for the LED light test a year ago. The measuring station originally had 56 double-tube electronic ballast-type fluorescent lamps distributed on the upper and side walls of the distribution frame. According to the working area of ​​the measuring platform, the lighting in the measuring platform is re-arranged, single-tube lamps are installed in the general working area, double-tube lamps are installed in important work places, and the height of the lamps in the measuring table is re-worked according to the work needs. Adjustments were made. The original electronic ballast type fluorescent lamps in the converted measuring table were all replaced with LED energy-saving lamps, and some aging lighting lines were replaced at the same time. Before the renovation, the annual electricity cost of the Shandong Road measuring platform lighting was 14,438 yuan, 4,106 yuan after the transformation, the annual electricity saving was 12,377 yuan, and the electricity saving rate was 75%. The effect was very obvious. The project has invested a total of more than 10,000 yuan, including replacement of LED lighting and distribution line transformation, saving one year of electricity bills to recover investment. The modified measuring platform not only saves electricity costs, but also eliminates the fire hazard of the lighting and reduces the frequency of replacement of the lighting.
According to statistics, Qingdao Unicom's 16-terminal measuring station computer room uses a total of more than 900 40W fluorescent lamps, and the annual electricity consumption is about 31.5 million degrees. According to the effect of the lighting modification of the Shandong Road measuring platform, the annual electricity consumption can be more than 200,000. degree.
