전기철도 속도향상에 따른 전차선로 가선 시스템 최적화에 관한 연구
A Study on the Overhead Contact Lines Optimization According to the Increased Train Speed
초록
The optimization of the overhead contact lines according to the increased train speed is to design the low-sag-wire so that the pantograph can follow the vertical fluctuation of the catenary. Main factors for the overhead contact lines design include the span, dropper interval, movable bracket, vertical fluctuation of the catenary, tension, and wave propagation speed. In this paper, a model is proposed to improve the electric railway speed, and the speed improvement analysis technology is examined to ensure the stable and reliable electric railway. In addition, the effect between pantograph and catenary according to the speed improvement is quantitatively analyzed by using simulation.
