摘要/Abstract

摘要： 为获得弓网电弧辐射特性及从理论上分析其对机场下滑信标的影响。选择典型电气化动车线路，首先基于CISPR16-1标准，利用电磁干扰接收机对电分相和普通点处的弓网电弧电磁辐射进行点频测试，获得了其在下滑信标台频谱内的辐射特性，然后基于电波传播理论，以电气化轨道平行跑道为例，分析了弓网电弧电磁辐射对飞机导航的影响。结果表明：电弧电磁辐射具有一定的随机特性，普通点处产生的电磁辐射场强小于电分相处；普通点的电磁辐射不会对飞机的导航产生干扰；当轨道距跑道中心的距离分别为700、120和60 m时，电分相拉弧点距下滑信标台天线的距离应分别小于3 291、546和249 m时才不会对飞机的导航产生干扰。本结果能够为轨道电气化和民用航空这两大工业体系在机场区域的电磁兼容性设计提供依据。

Abstract: The radiation characteristics of the pantograph-catenary arc and its influence on the airport glide beacon are studied. A typical line of electric multiple units is chosen in the study. According to the standard of CISPR16-1, the electromagnetic radiation of the pantograph-catenary arc at the neutral section and the general point is measured using the electro magnetic interference receiver, and its characteristics in the spectrum range of the glide beacon are obtained. Based on the wave propagation theory, the impact of electromagnetic radiation on the airport glide beacon is analyzed for the case of the electrified railway paralleled to the runway. The results show that the electromagnetic radiation is random, and the strength of the radiated electric field of the general point is less than that of the neutral section. The airport navigation will not be affected by the electromagnetic radiation of the general point. When the distance between the railway and runway center are 700, 120 and 60 m, the distance between the arc point of the neutral section and the antenna of the glide beacon must be less than 3 291, 546 and 249 m, respectively. The results can provide reference for the design of electromagnetic compatibility in the airport area.
