摘要
针对因电力机车引发高次谐波造成机车和接触网故障的情况进行地面和车上谐波测试,对测试结果进行分析并制定应对措施,对高次谐波造成的机车故障和供电设备故障起到较好的治理作用。最后对机车源头治理、供电方案优化、联合分析、机车上线前测试等工作提出具体建议。
With regard to the conditions of faults of locomotive and OCS suffering from the high-order harmonic caused by the locomotive,the trackside and onboard harmonic tests are made,the establishing of counter measures after analyzing of testing results play a better function of treatment of locomotive fault and power supply equipment fault caused by the higher-order harmonics.Finally,specific suggestions are put forward for locomotive fault and power supply scheme optimization,joint analysis and testing of locomotive before running on the line.
