青藏铁路海拔4000m以上短空气间隙修正研究

Study of the Correction of Short Air Gaps above 4000m Elevation along the Qinghai-Tibet Railway

根据在多功能人工气候室内完成的气压对短空气间隙交流放电特性影响的大量试验研究结果,系统分析了气压对短空气间隙交流放电特性的影响规律,提出了青藏铁路海拔4 000 m以上的短空气间隙修正系数。

According to an experimental study of the AC discharge performance of short air gaps under different air pressures in an artificial climate room, the effect of air pressure on AC discharge performance of various short air gaps is analyzed systemically in this paper. A correction coefficient of short air gap at the altitude above 4 000 a. s. 1. (?)
