The energy-saving transformation of the elevated street lamps on Yingtian street has been completed, saving at least 30% electricity.

the energy-saving transformation of the elevated street lamps on Yingtian street has been completed.

. It was learned from the street lamp management office of the Municipal Urban Management Bureau that after 12 all night efforts of street lamp maintenance workers, 1677 street lamps along the elevated Yingtian street were all energy-saving transformed in the early morning of November 26. LED lamps with higher luminous efficiency replace the original high-pressure sodium lamps. It is estimated that at least 30% of electricity can be saved

at 10:00 p.m. on November 23, the traffic of overhead vehicles decreased significantly, and the street lamp maintenance workers began to change their lights. At the section of Yingtian Street elevated near saihongqiao interchange, we can see that an engineering vehicle is parked in the South barricade, and two workers are standing in a 1 square meter platform, which is sent to the top of a 10 meter high street lamp pole by the lifting arm, removing the original high-pressure sodium lamp and installing a new LED lamp. At the bottom of the street lamp pole, the other two workers operate synchronously to pull out the old wires and connect the new wires. After 10 minutes, a street lamp was successfully replaced and turned on again

the area where the street lamp energy-saving transformation is implemented this time is Yingtian Street Viaduct (section from Qinhong South Road to Yangzi Avenue), with a total length of 9.8 kilometers and a total of 1677 street lamps. The operation is very difficult. In order to ensure the normal traffic of vehicles at night, we can't cut off power and change the lights. If we remove one lamp, it must be replaced and lit immediately. LIANGHAI, manager of the facility maintenance department of the street lamp Department of the Municipal Urban Management Bureau, said that when the operation is smooth, one lamp can be replaced in 10 to 20 minutes. In case of special circumstances such as disconnection, it will take 40 minutes to 1 hour

although the energy-saving transformation of street lamps is time-consuming and heavy, in order to ensure that the lighting rate of street lamps in the main urban area is above 99%, more than 100 street lamp maintenance workers in the street lamp Department of the Municipal Urban Management Bureau still have to complete daily inspection and maintenance from Monday to Thursday night. From November 2, every Friday to Sunday, from 10:00 p.m. to 6:00 a.m. the next day, we spent 12 overnight to complete the transformation task. LIANGHAI said that the first weekend was warm, and it was cool for everyone to wear thick work clothes to work on the elevated ground. In the second week, the energy consumption of 100million tons of standard coal was reduced. At the end of the second week, the weather began to turn cold. Wearing down jackets could not stop the wind from pouring in. Several artificial people got cold all night

in order to complete the transformation task with quality and quantity, the street lamp Department of the Municipal Urban Management Bureau gave full play to the exemplary role of Party members, named the engineering vehicle group with Party members but experience has shown that it was a party member vehicle group, and awarded the Party member pioneer number. Among the more than 100 maintenance workers, there are 39 party members. They arrive at the unit oneortwo hours in advance every night to make preliminary preparations. During on-site operation, the Party member fleet sets an example, and the operation is more standardized and faster, playing a good exemplary and leading role. Huangliben, a member of the facility maintenance branch of the street lamp Office of the Municipal Urban Management Bureau, said that weijianqiang, a member of the lighting office, although he had no street lamp maintenance skills, volunteered to drive a pickup truck to deliver lamps overhead and insisted on delivering more than 10 times and hundreds of lamps every night

the street lamps along the elevated Yingtian street have been running for more than 10 years. The lamps are old and the lighting quality is much lower than before. At that time, all the lamps installed were high-pressure sodium lamps, which consumed a lot of energy. After the energy-saving transformation, the light changes from yellow to warm white, which is brighter, more uniform and comfortable, and the lamp has a longer service life and lower energy consumption. Compared with the service life in the laboratory, the high-pressure sodium lamp has more than 10000 hours of operating the instrument at a fixed speed, and the LED lamp has 50000 hours. Liang Hai said that when the same brightness is used, LED lamps can save at least 30% of electricity. Moreover, all the LED lamps installed this time are equipped with adjustment lines. For example, when the natural environment is bright in summer, the power of LED lamps can be appropriately reduced, and the energy consumption will be smaller

it is learned that several years ago, the energy-saving transformation of street lamps on the West trunk road of the city was completed. This year, the energy-saving transformation of street lamps on the East trunk road and Yingtian Avenue was completed. Next year, the city plans to implement the energy-saving transformation of street lamps on the model road and Jiangdong expressway. At that time, the Jingzi inner ring expressway in our city will all light up the LED energy-saving lamps, upgrade the lighting facilities, save energy and reduce consumption. The applicable materials: plastic plates, pipes and profiled materials will also be more harmonious and unified with the surrounding landscape lighting environment
