摘要:
爲獲取波動載荷下弓網滑動電接觸載流特性,利用FCH-03型銷盤式滑動電接觸摩擦磨損試驗機模擬弓網接觸狀態,進行強電流密度、不同速度與波動接觸壓力條件下的浸金屬碳/銅對磨實驗。根據實驗數據獲得載流效率、載流穩定性在不同條件下的特性規律,並針對影響受流的運行速度、接觸電流、波動接觸壓力等因素作出深入的機理分析及電弧能量幹擾相關性分析。研究表明:載流效率隨接觸壓力振幅的增大而減小,隨接觸壓力頻率的增大呈較小的增大趨勢。載流穩定性隨接觸壓力振幅的增大而減小。低速時基本不隨接觸壓力頻率變化;高速時隨接觸壓力頻率增大呈先增大後減小。弓網離線及離線電弧是導致高速弓網系統載流質量下降的主要原因。
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.
