摘要
介绍了一套完整的电力机车自动接触网相分段的方案及其在川黔线应用。阐述了电力机车自动过分相过程中的过电压及涌流产生的机理,提出了一种抑制过电压及涌流方法,并对实际电力机车录制的电压、电流波形进行了分析。
The authors Introduce a scheme for automatic passing phase insulator of electric locomotive and its application in Chuan-Qian railway. The mechanism of the occurrence of overvoltage and overcurrent is presented and a method of restraining them is proposed. The measured waveform of overvoltage and overcurrent is analyzed.
