400km/h급 균압드로퍼의 통전특성에 대한 연구

초록

High speed train receives the power through contact with an overhead contact wire with its pantograph, and the droppers which have a major role to connect contact wire to messenger wire. The equalizing dropper developed for 400km/h speed is constructed that the dropper end clamp consisting of clamp for messenger wire, dropper wire and clamp for contact wire is assembled by surface pressure. The equalizing dropper will move up due to the friction with pantograph of train, and if the train passes, then dropper will move down, and this kind of up-down vibration will be repeated. This study is conducted to ensure if the dropper developed for 400km/h speed can carry the required current constantly under the said repeated up-down vibration.
