摘　　要：中低速磁浮铁路电磁环境复杂,车载BTM设备极易受到电磁干扰,影响列车列控系统正常运行。以凤凰磁浮项目为依托,详细收集车载BTM调试过程中发生的故障及磁浮列车各种工况下现场电磁环境测试记录,通过对比分析,确定电磁干扰的主要来源及耦合途径,并针对电磁干扰传导途径,制定一系列抑制BTM设备电磁干扰传导的措施。测试结果表明,这些措施能够有效抑制电磁干扰在BTM设备上传导,提高BTM设备电磁环境的适应性。为解决车载BTM设备电磁干扰提供借鉴,也为后续中低速磁浮铁路的建设和运营积累经验。The electromagnetic environment of medium-low speed maglev railway is complex,and the on-board BTM equipment is extremely vulnerable to electromagnetic interference,which aff ects the normal operation of train control system.Based on the Fenghuang Maglev project,this paper collectes in detail the faults occurred during the commissioning of the on-board BTM and the fi eld electromagnetic environment test records of maglev train under various working conditions.Through comparative analysis,the main sources and coupling paths of electromagnetic interference are determined,and a series of measures to suppress the electromagnetic interference conduction of BTM equipment are formulated according to the electromagnetic interference conduction path.The test results show that these measures can eff ectively restrain electromagnetic interference from conducting on BTM equipment,and improve the adaptability of BTM equipment to electromagnetic environment.The research methods adopted in this paper and the preventive measures against electromagnetic interference of BTM equipment provide a reference for solving electromagnetic interference of on-board BTM equipment,and also accumulate valuable experience for the subsequent construction and operation of medium-low speed maglev railway.
