摘　　要：为了从实测与标准的比较上研究磁浮列车电弧对机场VHF(甚高频)的影响,在国内某磁浮线路选取一些典型位置,采用点频测试和峰值、准峰值、平均值的检波方式在VHF的工作频段内开展磁浮列车电弧的电磁辐射测试;在获取标准10 m法处的电磁辐射特性后,结合GB/T 6364《航空无线电导航台(站)电磁环境要求》和MH 4001.1中关于保护率的相关要求对其进行电磁兼容分析,得出保护距离与磁浮列车电弧辐射特性的关系。研究结果表明:当磁浮列车线路与机场跑道延长线的距离大于183 m时,该磁浮列车电弧辐射不会对VHF的正常工作造成干扰。本文的研究结果可为机场区域轨道交通化和磁浮列车的选址提供依据。In order to study the effect of maglev train arc on airport very high frequency(VHF)from the comparison of actual measurements and standard,some typical positions were selected in one of domestic maglev line.Point tests as well as the detector mode of peak,quasi peak and average value were selected to carry out the electromagnetic radiation tests of maglev train arc in the working frequency of VHF.After acquiring the electromagnetic radiation characteristics of standard 10 m method,according to the requirement of GB/T 6364 and MH 4001.1 related protection rate,the electromagnetic compatibility of arc radiation was analyzed.The relationship between protection distance and radiation intensity of maglev arc was given.The result shows that when the distance between the maglev train line and the airport runway extension line is greater than 183 m,the arc radiation of maglev train will not interfere with the normal operation of the VHF.The results in paper can provide a basis for the location of the airport regional rail transit and maglev train lines.
