摘　　要：目前,国内外还没有进行过海拔4000m以上地区电气化铁道绝缘子闪络特性研究。本文根据青藏铁路电气化工程需要,在人工气候室模拟了电气化铁道常用的几种绝缘子工频电压闪络特性,对模拟结果进行了分析,并给出了相应的回归公式。So far, in the region of 4 000 m more above sea level, there have not carried on the study on flashover performance of insulator of electric railway at home and abroad. According to the need of the electrification engineering of Qinghai-Tibet Railway, the test of flashover performance under the Power Frequency voltage about several insulators that are commonly used in electric railway, is simulated in the artificial weather room. And the Recursive formula is got.
