A Study on the Interface between a G7 Pantograph and a KTX Catenary System in Preparation for G7 On-line Tests in the Korea High Speed Test Track

고속 시험선 구간에서의 G7 본선 시운전에 대비한 G7 팬터그래프와 KTX 가선계와의 인터페이스 연구

It is necessary to perform a study on the interrace between a G7 pantograph and a KTX catenary system prior to G7 on-line tests in the Korea High Speed Test Track in order to predict how high current collection quality can be obtained during the on-line tests and check if safety problems shall be caused b)Y the tests or not. According to the simulation results, current collection quality of the G7 pantograph at 350km/h is lower than that of a GPU pantograph at 300km/h, but the contact wire uplifts and average contact forces are within the safe-zone. In addition, the ratio of running speed (350km/h) to safe running. Therefore, the G7 on-line tests at 350km/h in the Korea High Speed Test Track is expected not to cause the safety problem.
