摘 要: 针对MR-139型动车组车体接地电阻的高频特性展开研究,讨论由于电阻器机械结构所引入的高频寄生参数,建立该元件的高频等效电路模型及电阻温度漂移模型。根据高速动车组运行过程中的不同工况,设计了3种测量接地电阻阻值的方法,并建立适合设计过程中预测计算接地电阻阻值的简化模型。根据所设计的测量方法对接地电阻的冲击阻抗特性、高频阻抗特性以及温度漂移特性进行了实际的测量,并针对测量结果进行了分析,证明所提出的测量方法能够实现在车辆现场进行在线测试。

Abstract: This paper researches high frequency characteristics of earthing impedance on basis of MR-139 and discusses the high-frequency parasitic parameters introduced by resistor mechanical structure. At the same time, the high frequency equivalent circuit model of the element is built, and simplification of prediction for the design process is proposed. Furthermore, the simple measurement method is designed, which can realize the online test of dynamic characteristics including shock impedance characteristic, high-frequency impedance characteristic and temperature drift characteristic in the field of earthing impedance.
