Zhuzhou Lighting Management Co., Ltd. Practices Energy Saving and Consumption Reduction

In the past few days, when night falls, the streets of Zhuzhou are bright and the entire city is like a sea of ​​lights. Many citizens have taken to the streets to enjoy the beautiful scene of Zhuzhou. On the evening of September 21, Mr. Chen, who was walking with her daughter on the roadside of Tiantai Road, said with emotion: “I’ve traveled to many places and I’m proud to be proud of it. The feeling is that Zhuzhou has become more and more beautiful compared to other cities in the world. You look at the street lamp's beautiful shape, its elegant colors, and its glare.

This is just a microcosm of the promotion of energy-saving lamps, implementation of energy-saving and consumption-reduction, and promotion of the harmonious development of Zhuzhou's "two-type society".

Explore new energy efficiency initiatives

With the continuous expansion of the city's urban area, the street lighting line becomes longer and the number of street lamps has also multiplied. Up to now, the city has a total of 35,062 miles of street lights, a length of 10,126.66 kilometers, a total of 494 control boxes, and 85 special transformers. The street lights dispelled the darkness, brought light, and made it easy for people to travel, but the power consumption also went up with the “rise of the boat”. The reporter learned from the Lighting Management Office of the Urban Management Bureau that in 2001, the total power consumption of the city’s urban street lights was 454kv, which rose to 2994kv by the end of 2009.

According to Director Liu Hailong of the lighting management department, “Over the years, we have responded positively to the call of the municipal party committee and the municipal government to regard energy conservation and consumption reduction as an important task of our department, and we have endeavored to explore and implement street lamp energy saving measures. As early as 2004, Before the Changsha-Zhuzhou-Xiangtan urban agglomeration became a pilot city of “two-society”, Zhuzhou Lighting Co., Ltd. conducted market-oriented operation through the contract energy management model, introduced energy-saving equipment for energy-saving lamps from Shenzhen, adjusted lighting time, and adopted New and high-efficiency light sources, scientific and reasonable maintenance of lighting facilities, computer monitoring systems and other initiatives to save energy and reduce consumption.At the same time, from the source management, all urban lighting projects newly built, reconstructed, and expanded in the city have strictly implemented the lighting project drawing review system. To put forward opinions on the lighting engineering design drawings that do not comply with the Ministry of Construction and the relevant national green energy-saving regulations, and require that the reforms be carried out in the most optimized and scientific manner to achieve the goal of energy saving and consumption reduction.The implementation of these measures not only eases the load pressure of power operation, but also ensures the urban areas. The normal lighting of street lamps has promoted Zhuzhou's "two-type society" harmony. Development can proudly say that Zhuzhou Lighting Management Department has always been a leader in the street lighting industry in our province."

Energy-saving lamps become "main force"

In the lighting management office compound and in the warehouse, the reporter saw a lot of busy figures: Some people were arranging piles of lamps and lanterns that were replaced, some were collecting new energy-saving lamps, and some people were negotiating the National Day Lighting Program... accompanied by reporters The Chief Engineer of the Lighting Management Department told the reporter: “The end of September is the busiest time for us. It is necessary to install new energy-saving lighting fixtures and also to arrange the National Day lighting project. Basically it is '5+2' and 'White+Black'. Axis rotation."

According to reports, most of the street lights in the city have gone through three stages: the incandescent stage was initially followed by the high-pressure mercury lamp, which is currently a high-pressure sodium lamp, and our city is no exception. Neon lights, floodlights, incandescent lamps, in line with the requirements of spending less money and bright, seemingly very affordable, in fact, more power consumption, but can not feel it in a short time. The energy-saving lamps have a one-time investment, but they can avoid the secondary pollution of mercury overflow from the rupture of fluorescent tubes, and have a long service life and power saving. In the long run, they are still saving money. Since 2001, the municipal government has successively replaced mercury lamps. Up to now, mercury lamps with energy consumption of over 125 watts and low luminous efficiency have been replaced with 110 watt high-pressure sodium lamps with low energy consumption, high luminous efficiency, environmental protection and energy conservation, and strong penetrating power, serving as the main force for urban street lighting. The construction of street lights in 33 streets and alleys in the city and the renovation of street lights for 10 roads have been completed, and most of the newly installed 900 street lamps use high-efficiency energy-saving lamps such as LED. It is estimated that only this one item can be used each year. Saving more than 400,000 degrees.

In addition, for those road sections that are temporarily not suitable for retrofitting energy-saving lamps, the Lighting Management Division has installed high-efficiency light-cutting lighting fixtures, which not only reduces the power consumption but also satisfies lighting requirements.

The promotion of a large number of energy-saving lamps not only saves electricity, reduces electricity bills, reduces light pollution in urban areas, but also improves urban taste. Some energy-saving lamps are works of art, which make people watch and admire them. Master Chen, who lives in Qianjin Village of Hetang District, said happily: “In the past, the street lights in the community were very dazzling. Now that the energy-saving lamps have been replaced, the light is soft.”

Look at the sky to turn off the lights

Just after 12 p.m., the lights on both sides of the Huanghe North Road began to change: As the traffic flow, the flow of people became less, the lights turned bright and dark, and the soft lights made the night quiet and peaceful. This is the city's lighting management office to increase energy saving technology, the implementation of street lights automatic monitoring system to bring about the joy of change.

It is understood that in the past few years, the city's street light control system was mainly controlled by time, and the work flow of “turning lights on to turning lights on until they turned off” was implemented. Its flaw was too old and could not be automatically changed depending on the weather conditions. In the evening, when the sky is not dark, the street lights will be on. In the morning, the sky is already bright and the street lights are still “sticking to their posts.” This wastes energy and the public’s response is not good.

In order to change this phenomenon, in 2007, through many years of exploration, the department started a set of domestic advanced, best computer monitoring and management systems in the province, making full use of modern control technologies, and adopting factors such as latitude, longitude, and climate. The automatic switch controller installed in the streets and alleys carries out point control, precise opening and closing time, and does its utmost to save energy. In this way, the city can save more than 3 million kWh of electricity each year, and Zhuzhou's energy-saving street lamp monitoring is at the forefront of the province's street lamp industry.
