为了获取不同类型电气化列车车体内通过窗口的工频磁场透入量及其分布特性，根据高速列车、动车、普通列车车体内磁场测试数据以及GB／T 24338—2009《轨道交通电磁兼容》对磁场测试结果进行了分析；结合电气化铁路供电及车体结构特点，建立了列车窗口工频磁场电磁感应模型，并将模型理论计算结果与实测结果进行比较。结果表明：车体内实测磁场分布与该模型的理论计算结果吻合，窗口透入工频磁场与牵引电流正相关；模型计算结果与实测结果之间的误差可控制在±5％，验证了模型的正确性。

In order to obtain the flux density and distribution characteristic of the power frequency magnetic field (PFMF)transmitted into the carbodies through windows of different electrified trains, the PFMF measurement data from high-speed,motor and ordinary cars were analyzed by GB/T24338 (Railway Applications Electromagnetic Compatibility ). According to characteristics of traction power supply and carbody structure of electrified trains,a model for calculating the power frequency magnetic flux density from car windows was established,and the calculation results of the model were compared with the practical measurements to verify its effectiveness. The results show that the magnetic flux distribution obtained by the proposed theoretical model is consistent with the measurement data,and there is a positive correlation between the PFMF transmitted through vehicle windows and the traction current. The error between calculated results and measurements is within ± 5%,which verifies the validity of the model.
