| 摘 要： | 高寒、高海拔环境条件会对电气化铁道牵引供电设备有降低外绝缘强度及促使SF6气体液化等不利影响,本文以青藏铁路西格段SF6气体绝缘牵引供电设备的选型为例,对海拔4000m使用设备的外绝缘试验电压的修正系数、外绝缘爬电距离以及设备内所充气体的种类与压力提出建议。

| Abstract: | The high elevation and lower ambient temperature environmental have adverse effects to the electric railway traction power systems electric equipment： the decrease of the equipment external insulation level and the liquefaction of the SF6 gas and so on. Based on the selection of the equipment with SF6 gas insulation in Xining - Ge＇ermu Railway, this paper make recommendations to the correction factor of equipment outside insulation test voltage, external insulation creepage distance and the gas inside the equipment in 4 000 m above sea level area. |
