China News Service, Beijing, March 2 (Reporter Zhou Yin) The reporter learned from China Railway Construction Co., Ltd. that on the morning of the 2nd, the Zheng (zhou) Xu (Chang) municipal railway project invested and constructed by the China Railway 16th Bureau Group The transmission of electricity across the Xuchang section marks the realization of the “electricity connection” of the Zhengxu Municipal Railway Project, laying a solid foundation for the next step of joint commissioning and testing.
The Zhengzhou-Xuzhou Railway connects Xinzheng Airport, Zhengzhou Airport Economic Comprehensive Experimental Zone, Changge, and Xuchang, and runs through the core area of Zhengzhou-Xuchang Industrial Belt in the Central Plains urban agglomeration. An urban railway connecting the core areas of the two cities.
Among them, the Xuchang section of the Zhengxu City Railway Project has a total length of 33.693 kilometers, with a total of 11 stations, 1 main substation for prosperity and 1 main substation for Tongda.
The power transmission will make the traction hybrid step-down substation and catenary within the range from Shuangmiaoli Station to Xuchang East Station (including Meizhuang parking lot) electrified.
Dai Weichao, the head of the Zhengxu "Four Electricity" project of the Electrification Company of the China Railway 16th Bureau Group, introduced that the Zhengxu Municipal Railway is the first municipal railway in China to use the energy storage regenerative energy absorption device technology. The regenerative energy absorption device stores the excess regenerative braking energy generated when the train is braking, and then transfers the stored electric energy to the DC catenary when the train starts, so as to realize energy reuse and achieve the purpose of energy saving and emission reduction.
According to industry insiders, the Zhengxu Municipal Railway is an important transportation support for realizing the integrated development of Zhengxu and Xuzhou and strengthening the radiation capability of central cities. Through the "high-density, short-marshalling" public transport operation, it will undertake commuting between urban groups and sub-central towns. The passenger flow drives the industrial development and population gathering along the route, strongly supports the development pattern of the urban agglomeration planning, and is of great significance to promoting the economic and social development of the urban agglomeration in Henan Province.
