Study of composition draft on automatic changeover system in neutral section of electric railway catenary system for high speed train line

초록

The neutral section was installed in order to prevent conflict with different phase angle source in electric railway catenary system. The speed of electric train reduced due to coasting operation by notch off when it passed the neutral section. And, the catenary wire was damaged and the accident might be appened because of the arc generation when the electric train passed the neutral section with notch off condition. In this paper, we present the draft of configuration on auto-changeover system in neutral section of electric railway catenary.
