摘　　要：针对电气化铁道的接触网与机车受电弓发生弓网离线事件期间产生火花电磁脉冲骚扰发射的现象,综合车速、定位点跨距、弓网接触压力、空气击穿电压等因素,提出产生该噪声的条件的数学模型。在此基础上进行的计算机数值仿真与骚扰的APD统计测量,可以为预测火花脉冲对铁路车载通信系统的干扰影响提供参考。The occurring condition of pantograph-catenary disconnection event was analyzed combining several factors which included train velocity, anchor span, contact pressure, and break-voltage of spark gap, etc. Then a modeling method was proposed to describe this RF disturbance emission. Computer simulation has been performed to this model and the APD of the noise is provided for evaluate interference to railway communication system.
