摘　　要：在对巴西里约地铁1A线牵引系统及地面信号系统工作原理进行详细分析的基础上,确定了牵引系统回流与信号系统电磁兼容性影响的测试方法,并且通过现场动态及试验室静态测试验证了巴西地铁交流牵引不平衡电流在单列车运行时所产生的谐波成分对地面信号系统的影响在允许范围内。On the basis of detailed analysis of the working principle of traction system and the ground signal system in Rio Brazil Metro I.ine IA, this paper illuslrated the EMC measurement method of traction system between signal systems. Through statie lest in laboratory and dynamic test at spot verified that the Brazil train＇s ac traction system unbalanced harmonic current are within the permissitle range when a single train operated and can＇t influenced the signal system on the ground.
