| 摘 要： | 受流问题是制约电气化铁路提速的瓶颈之一,而弓网离线电弧是高速列车受流的关键问题.为了全面的把握弓网离线状态,设计了弓网离线模拟试验平台.实现正弦周期内不同时刻离线及回合过程的电弧放电现象,并采用示波器和数据采集卡实现对离合瞬间电压、电流和光强等波形的同步记录,为弓网离线检测法和列车受流质量的研究及抑制电弧危害打下基础.

| Abstract: | The problem of power supply of pantograph is one of the critical factors to constrain the speed of electrified railway.The arc between pantograph and catenary is the key issue for power supply of electrified railway.It is necessary to grasp the state of the pantograph arcing comprehensively and correctly.This paper designs a device of simulation platform and measurement system of arc between pantograph and catenary,which can produce pantograph arc at any time in the changed cycle of catenary-voltage.The oscilloscope and acquisition card are used to record waveform of voltage,current and light intensity of pantograph arc at one time,which can lay a foundation for the research of offline detection and current collecting and suppressing arc. |
