Challenges and Practices in Electrical Design for High-altitude Touristic Rail Transit
This paper clarifies the construction history and relevant technical standards of electrified rail transit in high-al-titude areas.Taking the Lijiang Tramway Line 1 as a case,it discusses the selection of reference altitude and calculation height for altitude corrections,and elaborates the altitude correction approaches for key electrical parameters such as insu-lation level,converter capacity,safety clearance of distribution devices,and current carrying capacity of the contact wires.
