Research On The Operation Performance Of High Speed Railway Contact Network

In the electrified railway system, the catenary is the protection of electric locomotive transportation, including important part is contact parts network, its stable operation in order to ensure the security of power supply plays a key role, especially for the high-speed railway, the stability requirements more stringent.The paper studies the impact of high speed railway contact parts network performance factors, understand the domestic and foreign research present situation and technical means and measures, grasp of the parts design, processing, manufacturing, environmental hazard remediation process measures, theory using importance analysis, contact network reliability analysis principle, to identify factors that affect the reliable operation of the equipment, and combined with the actual scene, the focus on high speed railway contact network the main parts of the fault reason analysis, describes the practical application of parts in the performance degradation or failure reason, summarizes the factors that influence the performance of. Finally, in view of the various influencing factors, puts forward the prevention and rectification measures, suggestions, guide the high-speed railway to improve the design, manufacture, construction, maintenance and other work.
