Research on the electric field noise radiated from pantograph-catenary offline arc
摘要
Abstract
To study the amplitude-frequency characteristics of electric field noise radiated from pantograph-catenary offline arc,the pantograph-catenary offiine 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 offiine 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 firtly and then increases with the increase of contact pressure.And the amplitude of the electric field noise increases with the increase of loop current.关键词
