Abstract
With the progress of electronic information technology and the development of smart cities, DC power supply and distribution technology and multi-functional information pole construction have received more and more attention. As the underlying perceptive carrier, the multi-function information pole is indispensable in the smart city construction. Combining multi-function information poles with DC technology is an innovative solution to the development trend of smart cities. This solution is designed by considering the requirements of electrical, communication and peripherals, we can further reduce power loss, improve reliability and safety by taking power from DC distribution network directly. The DC multi-functional information pole described above has been successfully connected to the DC distribution network of a compound in Huai’ an, Jiangsu Province. The demonstration application of DC power supply from multi-functional information pole at the terminal distribution network level has been realized.
