摘要
瓦日铁路濮阳—范县区段接触网过电压严重,频繁发生机车绝缘故障,本文根据现场实测数据分析了机车和接触网谐波过电压机理,提出了高通旁路滤波方案,并在2座牵引变电所实施,取得了显著的治理效果。
The overvoltage of OCS in Puyang Fanxian section of Wazir railway is severe,and locomotive insulation faults occur frequently.According to the measured data at site,the paper analyzes the mechanism of harmonic overvoltage of locomotive and OCS,puts forward a high pass bypass filtering scheme which has been implemented in two traction substations,with significant effect of treatment obtained.
