The entire Shanxi section of the Xiongxin High-Speed Railway has successfully completed power transmission to the catenary

China News Service, Taiyuan, November 11th (Yang Jing, Zhang Chengjun) In the early morning of November 11th, the entire contact network of the Shanxi section of the Xiongxin High-speed Railway successfully completed one-time power transmission, laying the foundation for the upcoming thermal slip test and joint commissioning.

According to reports, the catenary power transmission converts the high-voltage power of the local grid into 27.5 kV alternating current through the railway traction substation, and then transmits it to the catenary to continuously provide power for the speeding high-speed rail EMUs. As the core of the high-speed rail traction power supply system, the successful power transmission of the catenary is a key and landmark node for the railway project to shift from static construction to dynamic commissioning. It is an important prerequisite for the high-speed rail to have dynamic detection conditions and subsequent safe opening and operation.

In order to ensure the smooth completion of the catenary power transmission, the State Railway Taiyuan Bureau Daxi Railway Passenger Dedicated Line Co., Ltd. collaborated with participating units such as China Railway Construction Electrification Bureau Group Co., Ltd. to prepare a power transmission implementation plan, delineate the power transmission scope, operating procedures, safety technical control points and emergency response plans, and conduct debugging of various power supply equipment along the line in advance in accordance with specifications and standards, and orderly implement the catenary insulation conduction test and cold slip test to ensure that the traction power supply facilities meet the power transmission conditions.

"We have assigned dedicated personnel to monitor and monitor key areas, publish power transmission announcements through a combination of online push and offline posting, carry out safety publicity and education, and strengthen close cooperation with relevant units to ensure the safety and stability of power transmission operations." said Zhang Heng, a senior engineer specializing in four power stations at the Xiongxin Headquarters of the Daxi Railway Passenger Dedicated Line Co., Ltd. of the Taiyuan Bureau of the State Railway.

The Xiongxin High-speed Railway runs from Xiong'an, Hebei Province in the east to Xinzhou, Shanxi Province in the west. It is an important part of the Beijing-Kunming corridor of the national "Eight Vertical and Eight Horizontal" high-speed railway network. It is also the first high-speed railway in Shanxi with a design speed of 350 kilometers per hour. After the project is completed and opened to traffic, it will further improve the layout of the regional high-speed railway network and shorten the time and space distance between Beijing, Tianjin, Hebei and northern Shanxi. It is of great significance to promote the development of tourism resources, coordinated industrial development, and personnel exchanges along the line.
