摘要:
首先,从理论的角度分析了弓网离线电弧电磁干扰的产生机理和物理现象过程。然后,进行了半实物仿真试验来研究弓网电弧辐射噪声特性,利用天线接收弓网离线电弧的电磁信号,并探讨了铜棒和纯碳滑板之间的接触电阻量级。最后,对电磁辐射脉冲进行了快速傅里叶变换,将电磁信号从时域转化到频域研究。综合电弧电磁辐射的时域及频域特性的分析,表明弓网离线电弧产生的电磁辐射为强脉冲信号,持续时间短,频谱范围宽。
Abstract:
In this paper, the generation mechanism and physical phenomena of the off-line arc electromagnetic interference were firstly analyzed from the theoretical point of view. Then, the laboratory experiment was carried out to study the characteristics of the arc radiated noise, and the electromagnetic signals of the off-line arc of the pantograph-catenary system were received by an antenna. Next, the contact resistance magnitude between the copper rod and the pure carbon strip was discussed. Finally, a fast Fourier transform was carried out on electromagnetic radiation pulse, which transformed the electromagnetic signal from time domain to frequency domain. The analysis shows that the electromagnetic radiation produced by the off-line arc of the pantograph-catenary system is a strong pulse signal with a short duration and wide spectrum range.
