Abstract

Contact wires break because of the arc and large current flow generated between the pantograph and the contact wires when a train comes to a standstill at an insulated overlap. In this study, we confirmed the effectiveness of the function for putting out the arc of the compound catenary proposed as a countermeasure for this disconnection by on actual arc experiment. Moreover, we confirmed that the compound catenary proposed had predetermined current collection performance through simulation and traveling experiment. It was also it confirmed that the compound catenary proposed has a predetermined current collection performance also in the revenue line, and there was no influence on wear in the short term.
