Analysis of arc behavior between pantograph and overhead contact line at the Korea high-speed electrified railways

초록

With increasing speed of the train in electrified railway lines, there is a remarkably high demand for the failure analysis of current collection systems. Among the interaction between pantograph and overhead contact line in electrified railways arcs was the most serious problem. In this paper, we developed two kinds of detecting systems for analysis of the behaviours of electric arc between pantograph and overhead contact line with photo diode sensor and high-speed camera measurement type, respectively. The analysis and comparison of arcing in the proposed measurement systems are expected to be valuable measurement systems for arc behaviours for current collection system failure in the high-speed electrified railway
