丽香铁路牵引变电所电气参数高海拔修正的应用

为满足高海拔地区牵引变电所运行要求,应根据相关规范、标准及设计手册对高海拔地区牵引变电所电气设备的外绝缘耐受电压、安全净距及绝缘爬距等参数进行修正,以提高整个牵引供电系统的可靠性。本文结合丽香铁路设计,对高海拔地区牵引变电所电气参数修正的应用进行详细描述和分析,对类似高海拔地区牵引变电所亭设计提供参考和借鉴。

In order to meet the operation requirements of traction substation in high altitude area,it is need to correct parameters of external insulation withstand voltage,clearance and insulation creep distance of electrical equipment in traction substation according to relevant specifications,standards and design manuals and improve the reliability of the whole traction power supply system.On the basis of the design of traction substation of Lijiang to Shangri-La railway,the paper describes and analyzes in details the electrical parameters of traction substation in area with high altitude.It provides reference for design of traction substations in area with high altitude.
