The energy-saving lighting scheme for the Hangzhou Bay Bridge is initially fixed
The world's most important "World's first span" - how to solve the lighting problem of the Hangzhou Bay Bridge? The reporter learned from the Cixi Power Supply Bureau on the 27th that with the approaching official opening date, the power supply plan for the Hangzhou Bay Bridge has been initially determined. According to the plan, the power of the bridge will be provided by the Cixi Power Supply Bureau and the Jiaxing Power Supply Bureau. The power supply area mainly includes the bridge service area, the sea-viewing platform, and the line lights. In terms of scale, the daily power supply of the bridge is about 10,000 degrees, which is equivalent to the daily electricity consumption of a large-scale industrial enterprise in Cixi.
The bridge has a total of about 2,000 street lights, which is the main link of electricity consumption. How to save electricity? The bridge gave up the usual 400 watts of street lamps, and instead used 250 watts of high-voltage nano lamps, and the brightness was not affected. Even more amazing is the street light control system. The traditional control system can only "issue orders" for the switch of street lamps within one kilometer, and the bridge with new streetlight control technology can realize independent control for each lamp. According to the brightness of the environment, the switch can automatically switch the power according to the brightness of the environment.
The power saving benefits of the new program are considerable. According to the new scheme, the street lamp uses about 6,000 degrees of electricity per day, which is roughly estimated. Compared with the original plan, it saves more than 1000 degrees per day and more than 400,000 degrees per year.
