摘　　要：针对弓网离线电弧辐射电场噪声特性问题,利用弓网电弧电磁噪声实验平台开展了不同条件下的弓网离线实验,分析了弓网离线电弧电场噪声的幅频特性与接触压力和回路电流之间的作用关系.研究表明:弓网离线电弧辐射电磁噪声主要集中在30~500 MHz频段.随着接触压力的增大,弓网离线电弧辐射电磁噪声的幅值先减小后增大;随着回路电流的增大,电磁噪声幅值增大.To study the amplitude-frequency characteristics of electric field noise radiated from pantograph-catenary offline arc, the pantograph-catenary offline experiments under different conditions were conducted with the electromagnetic noise experimental platform in the anechoic chamber environment. The relationships between electromagnetic noise radiated from pantograph-catenary offline arc and contact pressure, loop current were analyzed. The frequency range of the electric field noise is mainly within 30 -500MHz. The amplitude of the electric filed noise decreases firstly and then increases with the increase of contact pressure. And the amplitude of the electric field noise increases with the increase of loop current.
