摘　　要：随着我国中低速磁浮系统的线路逐渐增多,其对电磁环境的影响也备受大众关注。该文系统地通过对中低速磁浮系统的电磁环境实测,系统分析中低速磁浮列车内、外电磁环境的时域、频域特性,牵引变电所的电磁环境特性,并将实测数据与相关国内外电磁环境标准对比,在中低速磁浮车内、站台、区间和变电所等处,各电磁环境参量(包括直流磁场、低频磁场、无线电干扰场强)均符合相关标准限值要求。中低速磁浮系统的电磁环境较好,对其内部及周围的设备和人员产生电磁影响概率较低,是一种值得大力推广的绿色城市轨道交通运输方式。With the increase of the lines of medium-and low-speed maglev system in China,its impact on the electromagnetic environment has also attracted public attention.In this paper,through the measurement of the electromagnetic environment of the medium-and low-speed maglev system,the time domain and frequency domain characteristics of the internal and external electromagnetic environment of the medium-and low-speed maglev train and the electromagnetic environment characteristics of the traction substation are analyzed systematically.The measured data are compared with the relevant domestic and foreign electromagnetic environment standards,in the medium-and low-speed maglev vehicle,platform,interval and substation.The electromagnetic environment parameters(including DC magnetic field,low frequency magnetic field,radio interference field strength)are in line with the relevant standard limits.The medium-and low-speed maglev system has a good electromagnetic environment and has a low probability of electromagnetic influence on its internal and surrounding equipment and personnel,so it is a green urban rail transit mode worth popularizing.
