机车辅助电源电快速瞬变脉冲群试验案例分析

摘要

The mechanism of production and harassment to EFT is employed to investigate the EFT problems of the locomotive auxiliary power. This paper studies the processing method and puts forward the solution to EFT problems of power line and IGBT. The experimental results show that, the EFT level of locomotive auxiliary power is efficiently improved,conformable to GB/T17626. 4-2008.%针对机车辅助电源电快速瞬变脉冲群( EFT)抗扰度问题，分析了脉冲群产生和骚扰机理，研究了脉冲群的处理方法，提出了针对电源线EFT问题的解决方法.试验结果表明，所提方法可以有效提高机车辅助电源EFT抗扰度等级，达到GB/T 17626.4—2008标准要求.
