摘要
介绍了测量列车牵引系统和辅助电源系统线缆上传导发射的现场测试方案。对测试布置、电流探头的选取进行了详细说明。并对测试要点、实验数据进行了分析。分析数据可知城轨列车动力电缆造成的干扰能量主要集中在1 MHz以下的频率段。
An On-site test procedure for conducted emissions in the cables of train traction system and auxiliary power system is introduced in the article. The application of this method in conducted emission test for signal system is outlined. By analyzing the measured data, it can be concluded that reference power of urban railway train cables mostly distributed below 1 MHz.
