Overview of Research on Arc Detection Technology and Evaluation Method of Pantograph-catenary System
The pantograph-catenary system is an essential and integral component of electrified railways,providing the only way for electric trains to obtain power.The arcing of the pantograph-catenary system is a crucial indicator for assessing the current collection quality of the system,with the benefits of convenient detection and intuitive evaluation leading to the development of va-rious arcing detection methods.These methods can be classified into two categories,direct and indirect detection.Direct detection involves the direct measurement of the arc based on electrical parameters such as current and voltage,while indirect detection in-cludes long-distance measurement based on characteristics such as acoustics,optics,and electromagnetic radiation.This paper provided a detailed discussion on the application scenarios,basic detection principles,and corresponding evaluation methods of these different detection methods.Furthermore,a comprehensive analysis of the advantages and disadvantages of these methods was presented,along with a discussion on the areas for improvement and enhancement of relevant standards for arc detection,as well as the main directions and development trends of subsequent arc detection research.
