CRH380A型重联动车组电磁干扰问题的探讨

Study of the electromagnetic interference in CRH380A multi-headed EMU

针对重联动车组运用中经常出现异常自动紧急制动、受电弓自动升降弓、网络传输异常等现象,通过线路运行跟踪检测、试验,及对相关线路信号设备、动车组局部控制电路进行修改设计、验证,提出了移动装备抗电磁干扰和优化牵引回流的改进措施和建议。

In view of the abnormal situation frequently occurred in multi - headed EMUs, such as self- activated emergency brake, self lifting or retracting of pantograph, irregular network transmission, etc. , tracking test and experiments during operation are conducted, relevant line signaling equipment and local control circuits on EMUs are revised and veri- fled, countermeasures and suggestions are made and the optimization of return propulsion current. for the protection of mobile equipment
