摘要
针对交直交型电力机车产生高次谐波对牵引变电所0.38kV侧产生不利影响,对其治理方案进行比较分析,研制了0.38kV二阶高通滤波装置,显著改善了所用电交流设备电源的电能质量,避免了因谐波过电压造成的设备损坏,有效保障了牵引变电所27.5kV所用电系统的安全运行。
With regard to the adverse effect to 0.38 kV side of traction substation caused by the higher-order harmonics generated by AC-DC-AC electric locomotive,analysis is made for its treating scheme,and 0.38 kV second-order high-pass filtering device is developed,it improves dramatically the auxiliary AC equipment power supply quality,avoids the equipment damage due to harmonic over-voltage,guarantees effectively the safety operation of 27.5 kV auxiliary system in traction substation.
