要約(英語): The breaking of contact wires occurs due to the arc and large current flow that are generated between the pantograph and the contact wires when a train comes to a standstill at an insulated overlap. Especially, when the arc occurs, it melts the contact wire, and subsequently, when it touches the additional wire above the contact wire, the catenary could break. This study first shows the potential differences and current at an insulated overlap, and then shows the maximum arc length through experiments. Using these results, the effectiveness of the countermeasures against the breaking of contact wires at insulated overlaps when a train comes to a standstill is demonstrated there.
