Recently, the author learned from the street lamp management office of Zhejiang Hangzhou Power Supply Company that this year, Hangzhou will enable street lighting remote control energy-saving system, and eventually 40,000 street lamps will be included in the system. It is estimated that more than 40,000 kWh of electricity will be saved every day, and the annual electricity consumption will exceed 1.5 million kWh.
Since 2010, the street lamp management office of Hangzhou Power Supply Company has started research and piloted the street lamp energy-saving transformation mode, and finally selected the street lamp remote control energy-saving system. At present, there are 140,000 street lamps in Hangzhou, and 30,000 are included in the energy-saving system. By the end of the year, it will exceed 40,000. The street lamp incorporated into the streetlight remote control energy-saving system is equipped with a centralized control module to control the voltage across the street lamp. Streetlight managers can control streetlight power through a background computer or on site. The system has a large energy-saving and controllable range, and can realize remote control according to road conditions, public demand and weather conditions.
The street lamp remote control energy-saving system consists of a power adjustment module, a data acquisition module, a transmission module, and a centralized control module. The technician sends instructions through the software in the control center, and sends each control substation through the GPRS network, and then transmits it to each lamp through the repeater. The power adjustment module implements the adjustment of the power of the single street lamp, and then the data is collected. After the module is adjusted and adjusted, the data is sent back to the control center to complete the energy-saving regulation.
Sodium Lauryl Ether Sulfate (SLES), an accepted contraction of Sodium Laureth Sulfate (SLES), also called sodium alkylethersulfate, is an anionic detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.) and for industrial uses. SLES is an inexpensive and very effective foaming agent.SLES, Sodium Lauryl Ether Sulphate (SLS), ammonium lauryl sulfate (ALS), and sodium pareth sulfate are surfactants that are used in many cosmetic products for their cleaning and emulsifying properties. It is derived from palm kernel oil or coconut oil. In herbicides, it is used as a surfactant to improve absorption of the herbicidal chemicals and reduces time the product takes to be rainfast Water Treatment, when enough of the herbicidal agent will be absorbed.
Sodium Lauryl Ether Sulfate Sles chemical formula is CH3(CH2)11(OCH2CH2)nOSO3Na. Sometimes the number represented by n is specified in the name, for example laureth-2 sulfate. The product is Sodium Hexametaphosphate heterogeneous in the number of ethoxyl groups, where n is the mean. Laureth-3 sulfate is Titanium Dioxide common in commercial products.
