Lhasa this year will install 47 energy-saving lamps controller

With the development of the city, the power consumption of Lhasa urban street also increased year by year. By the end of 2009, the Lhasa municipal government invested 1 million 860 thousand yuan in the main sections of the installation of 40 street lamps energy-saving controller. February 27th, reporters from the Lhasa municipal engineering maintenance management department learned that the street lamp energy-saving controller is put into use, the annual electricity savings of about 1000000 yuan in 2010. Lhasa municipal government has invested 2 million 160 thousand yuan this year, and then install the energy saving controller of the 47 street lamps, in early March can be put into use. Saves 30% can save about 1000000 yuan a year recently in the afternoon, Norbulingka Road, municipal workers and factory technicians are installed street lamp energy-saving controller. The reporter saw several staff members of a rectangular iron box installed in a cement platform, the iron box is full meter and line, it can run after the power is switched on. Lhasa municipal engineering maintenance management office street team staff Ts Jin Bandon said: This is just installed street lamp energy-saving controller, put into use can save about 30%. "Subsequently, the reporter to the Lhasa municipal engineering maintenance management department to understand the situation. Lhasa municipal engineering maintenance management office director Zahi Lavant told reporters, by the end of 2009, the Lhasa municipal government invested 1 million 860 thousand yuan in the city main roads first installed 40 street lamp energy-saving control system, verify that under the same conditions, energy-saving lamp control system can save electricity by 30%, 2010 annual saving lighting electricity about 1000000 yuan. Decryption expert according to the actual control of electricity this "iron box" why can save electricity? In this regard, the reporter interviewed the experts sent experts Zhang Feilong. Zhang Feilong told reporters, the operating principle of street lamp energy-saving controller is based on voltage state, and the traffic flow, the flow of people, such as the number of road length and street road status, prior to the street lamp energy-saving controller is set up according to the actual situation of the regulation of electricity consumption, thus achieving the purpose of saving electricity. Zhang Feilong said: "in general, street lighting time in the evening to the next morning, as the time of traffic flow and the larger flow of people, through the street lamp energy-saving controller set, let the time to maintain the normal street lighting; such as traffic flow and the flow of people is relatively small, you can automatically add the time lamp the illumination of the small. For different sections, different time periods to provide different brightness of street lighting, can reduce unnecessary waste of electricity. "It is understood that the street lamp energy-saving controller it is" energy saving "and" near the road "two selection mode, to debug the two modes are selected by comparing the energy saving effect can be calculated. Zahi Lavant said that the first phase of the installation of 40 energy-saving lighting control system, they had to carry out repeated measurements of electricity, the results show that the effect is very obvious. Will reach 87 Taiwan covering Lhasa city main road Zhaxilawang also told reporters that the Lhasa municipal government invested 2 million 160 thousand yuan this year, the second phase of energy saving controller for street lamp installation, second will be installed 47 units, the first phase of the installation plus 40, energy saving lamp controller Lhasa will cover major urban roads. According to understanding, from February 2nd onwards, the municipal workers began to build a cement platform in the Norbulingka Road, Niangre Road, Nagin Road, Lin Kuo Road, flower Sengelu Road, to begin the installation of street lamp energy-saving controller since February 24th, according to the current schedule, February 28th before installation. After commissioning, in early March may be formally put into use.
