Study On The Characteristics Of The Standard System Of The European Pantograph-Catenary System

As a normative documents, the standard system plays an important role in the maintenance of industry. With the rapid development of high speed railway and its construction today, the technology of Chinese railway standard system has been gradually built and improved. However, there are still some problems in Chinese pantograph-catenary system due to the late start of Chinese railway industry and the shallow understanding of the standard. Since the Characteristics of Chinese pantograph have always been similar to the characteristics of German pantograph, it is expected to provide some reference to perfect Chinese pantograph-catenary system by learning from Europe.The standard system of the European pantograph-catenary system is established on the basis of96/48/EC and Technical specification for interoperability (hereafter referred to as "TSI"). The standard system consists of EN50206-1, EN50119, EN50317, EN50318, EN50367. The standard system has six characteristics including collectivity, integrity, correlation, decomposability, environmental adaptability and targeted. Contact force is the key parameter of the interaction quality of pantograph-catenary system.Firstly, the thesis demonstrates the core status of contact force in the pantograph-catenary system by studying the reflection of the collectivity and integrity in the standard system. Next, the thesis studies the standard establishment issues about the pantograph characteristics and test, overhead contact lines design, measurements and simulation of the dynamic interaction between pantograph and overhead contact line, technical criteria for the interaction between pantograph and overhead contact line of the correlation, decomposability, environmental adaptability and targeted of the standard system.In terms of the vertical movement of contact point, the maximum height at the contact point of the train with single pantograph and the front pantograph of the trains with two pantographs is100mm, and the maximum height at the contact point of the latter pantograph of the trains with two pantographs is120mm. In order to reduce the wear of the contact line and the contact strip to the least, the area of copper alloy contact wire should adopt carbon contact strip. Contact resistance at the contact point is inversely proportional to the contact force when the pantograph and contact line is relatively static. The increase of the train speed will lead to the contact force increase.The contact force is stipulated about the classification, value range, measurement and simulation, which is the internal factor that connect the standards of the European pantograph-catenary system. It also fully embodies the correlation of the standard system. The thesis comes to a conclusion by studying the changes of EN50119due to the decomposability. EN50119:2009removed the part of construction and supervise about overhead contact line on the basis of the2001version,which at the same time added the component requirements and testing part. These changes are due to the publishment of EN50317, EN50318and EN50367after2001.EN50367provides the evaluation criteria about dynamic interaction performance of the pantograph-catenary system. The EU Member States have different values in catenary and vehicle characteristics because of choosing a different kind of pantograph. The target requires the pantograph-catenary system to meet the fundamental purpose of the safe and efficient transmission. Meanwhile, it also requires the system to assure the macroscopic purpose of the interoperability of the trans-European high-speed railway system.Finally, through the comparison between the pantograph-catenary systems in China and Europe, practical suggestions to standard system of the Chinese pantograph-catenary system are given:We should take notice of the core issues in Chinese pantograph-catenary system, and formulate measurement and simulation standard based on environment in China as soon as possible. At the same time, we should endeavor to translate the standard system in China to make it becoming international so that China can have the power to influence the standard-setting in the world.
