A Simulation of Arc Generation at AC-DC Neutral Section of Electric Railway
This paper provides an experimental and theoretical analysis of the arc discharges generated between contact wire and pantograph of high speed railway. A video-based arc detection device is installed on the KTX train, and arc discharges are measured for a 45.87km track section of high speed railway in Korea. It is measured that the rate of contact loss is 0.3％ which is lower than the regulated value of 1.0％ for high speed train, and arc discharges induced by 21 small size contact losses and 6 medium size contact losses occur continuously along the track. The power of arc discharge between contact wire and pantograph is calculated as 9.0～22.5kW which is approximately onehundredth of that of the arc discharges generated at the neutral section of contact wire. The results of the measurement and the analysis suppose that a study be followed to suppress arc discharges and contact wire damages for the safe operation of high speed railway.
