基于弓网电弧模拟试验装置的电弧研究

摘要

One of the interaction features is the arcing between pantograph and catenary. We designed our own pantograph-catenary arc prototype can simulate sliding contact between pantograph and contact wire, therefore it can produce rotating arc. Experiments Max voltage is 80V and Max current is 8 A, the voltage and current waves have recorded when arcing operation. The harmonics components are analyzed based on the LABVIEW software%设计了一套弓网电弧模拟发生装置，该装置通过旋转轮盘与碳刷相对运动，产生旋转电弧，能够模拟受电弓与接触网的相对运动。系统试验最高电压80v，负载电流8A，试验测试了电弧对系统的电压、电流的影响，并采用LABVIEW软件对其进行了谐波分析。
