摘要
列举高海拔地区电气化轨道交通的建设历史及相关技术标准,以丽江有轨电车1号线为例,讨论了海拔修正基准高度和计算高度的选择,并介绍了绝缘水平、变流器容量、配电装置安全净距和接触线载流量等关键电气参数的海拔修正思路.
Abstract
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.
