Design Essential Element Technology of Catenary System be in Correspondence with Speed-up

고속화에 대응한 전차선로 설계 요소기술

The decisive criteria to determine collection performance is the contact force between pantograph and catenary. The contact force consists of a static force and dynamic force related to vibration characteristics, train speed and etc. The low contact force leads to the loss of contact, and most countries regulate it below 1% at operation speed. This study presents a technical overview of criteria for collection performance of catenary system.
