摘要/Abstract

摘要： 弓网系统电磁噪声不但危害行车安全,而且对铁路沿线的通讯和周边居民的健康产生不利影响。通过研究弓网电磁噪声的辐射特性,为抑制其辐射强度提供理论基础。建立了弓网系统离线电弧的Matlab仿真模型,通过仿真得出电弧的放电特性和频谱范围。利用有限元分析软件对弓网电弧放电的典型频率进行仿真分析,得出弓网电弧的典型频率的远场和近场特性。仿真结果表明：弓网离线电弧的主要频段为30~100 MHz,这个范围内电磁辐射的幅度相对严重。另外由于受到受电弓以及滑板的影响,电弧的辐射场不对称,不同方向上辐射的场强均不同,车厢的前端和尾端是主要的辐射方向。

Abstract: Pantograph-catenary system electromagnetic noise radiation not only endangers traffic safety, but also adversely affects the health of nearby residents and communications along the railway. By studying the radiation characteristics of the electromagnetic noise of the pantograph-catenary, provide a theoretical basis for suppression its radiation intensity. A Matlab simulation model of the pantograph offline arc was established, the simulation result shows out the discharge characteristics and the spectrum bounds of the arc. Then using the finite element analysis software to do a simulation analysis about pantograph typical frequency of the arc, the far-field and near-field characteristics based on the pantograph typical frequency were obtained. The result shows that: the main offline arc band is for 30~100 MHz, within the range of the electromagnetic radiation amplitude is serious. Additional, due to the impact of the pantograph and slide plate, Arc radiation field is asymmetrical, the radiation field intensity in different directions is different, the compartment front and tail ends are the main radiation direction.

Key words: pantograph offline arc, electromagnetic noise, simulation, finite element analysis, radiation field strength
