摘要:
为获取波动载荷下弓网滑动电接触载流特性,利用FCH-03型销盘式滑动电接触摩擦磨损试验机模拟弓网接触状态,进行强电流密度、不同速度与波动接触压力条件下的浸金属碳/铜对磨实验。根据实验数据获得载流效率、载流稳定性在不同条件下的特性规律,并针对影响受流的运行速度、接触电流、波动接触压力等因素作出深入的机理分析及电弧能量干扰相关性分析。研究表明:载流效率随接触压力振幅的增大而减小,随接触压力频率的增大呈较小的增大趋势。载流稳定性随接触压力振幅的增大而减小。低速时基本不随接触压力频率变化;高速时随接触压力频率增大呈先增大后减小。弓网离线及离线电弧是导致高速弓网系统载流质量下降的主要原因。
Abstract:
In order to gain current carrying characteristics of pantograph catenary sliding electrical contacts under fluctuating loads, by using FCH-03 type pin on disc sliding electrical contact friction and wear test machine to simulate the running state of pantograph catenary system, a lot of experiments were carried out to the copper/ leaching copper carbon slide under fluctuating load, different speed, current conditions. According to the experimental data the curves of current receiving efficiency and current carrying stability under different conditions are drawn, and the theoretical analysis to the sliding speed, current and fluctuating load that affect the current receiving efficiency and correlation analysis of arc interference are carried out. The research shows that the increase of current efficiency with the contact pressure amplitude, decreases with the increase of frequency is smaller increases. The current carrying stability decreases with the increase of the contact pressure amplitude, and does not change with the frequency of contact pressure at low speed, with the increase of contact pressure high speed, it increases first and then decreases. Pantograph-catenary off-line and off-line arc are the main causes of high arch net current carrying quality decline.
