350 kph! Intelligent EMU "test run" Beijing Zhangjiakou high speed railway
At 8:30 on November 7, 05301 train left Qinghe station, marking that China's fully independent intellectual property rights intelligent EMU officially participated in the joint commissioning of Beijing Zhangjiakou high speed railway.
according to the relevant person in charge of Beijing Railway Bureau, on the same day, the intelligent EMU started from Qinghe station, mainly carrying out joint commissioning and joint test between Changping Station and Xiahuayuan North Station of Beijing Zhangjiakou high speed railway, with the maximum test speed of 350km / h.
it is understood that since the comprehensive test train was put on line on October 5, the speed of single EMU was increased step by step on the up and down lines of Beijing Zhangjiakou high speed railway. On October 20, the speed of up and down lines reached 385km / h, meeting the standard of "the highest test speed is 110% of the design speed of the line". At the same time, the joint commissioning and trial operation of Chongli railway began on October 22.
through the comprehensive detection of the train and the detection and confirmation of the train, the dynamic detection is used to carry out the comprehensive test on the interface and matching relationship between various systems and related systems, evaluate and verify the performance or function of traction power supply, contact network, telecontrol, communication, signal, customer service, disaster monitoring, earthquake early warning monitoring system, etc., verify the track, turnout, subgrade, bridge The applicability of structural engineering such as tunnel and sound barrier shall be evaluated to see whether the comprehensive grounding, electromagnetic environment, vibration and noise, phase separation device, etc. meet the requirements of relevant standards, provide technical support for the commissioning and optimization of all business systems and the overall system of the whole line, make the functions and performance of all systems and the overall system meet the requirements of standards, and provide important technical support for the operation. The joint commissioning and test of Beijing Zhangjiakou high speed railway covers 17 major items and more than 6000 parameter items of various systems such as fixed facilities, mobile equipment, traction power supply, train control, passenger service, etc., involving dozens of units such as operation unit, construction unit, testing unit, main engine plant, design unit, construction unit, supervision unit, railway public security, etc., with more than 2000 people participating in the inspection, fine commissioning, security, etc All the work will ensure the smooth implementation of the joint commissioning and test of Beijing Zhangjiakou expressway.
