交流电气化铁路对机场甚高频设备电磁干扰分析

Analysis on Electromagnetic Interference of AC Electrified Railway on Airport VHFEquipment

为了实现更加便捷的交通换乘,将本地高铁和机场进行无缝对接已成为交通发展的一大趋势。但高铁和机场距离较近时,可能引起交流电气化铁路与对机场无线敏感设施的电磁干扰。本文结合工程实例,通过实地勘测、类比分析等手段,评估了交流电气化铁路运营期间对机场甚高频设备的电磁干扰影响,为铁路选线提供有力的技术支持,为交流电气化铁路对机场甚高频设备的电磁干扰防护提供参考依据。

In order to achieve more convenient transportation, seamless integration of local high-speed rail and airport has become a major trend in traffic development. However, it may causes electromagnetic interference between the AC electrified railway and the airport’s wireless sensitive facilities. This paper evaluates the electromagnetic interference effects of AC electrified railways on airport VHF equipment. It provides strong technical support for railway line selection. The conclusions can also provide reference for electromagnetic interference protection of airport VHF equipment for AC electrified railway.
