摘要
武威南—嘉峪关电气化线路采用关节式电分相结构,运行中分相处多次发生过电压,击穿车顶绝缘,引起变电所跳闸。本文结合试验统计结果,初步分析了电分相过电压的特征和原因,并提出了改进的建议。
Wuweinan-Jiayuguan electrified railway adopts articulated neutral section and there have occurred many times tripping of substation due to the over-voltage, breaking through of car roof ceiling insulation. With combination of test result, the article analyzes the causes of over-voltage at neutral section and puts forward the measures for improvement.
