高压大截面电缆运行电流大,发生短路故障时产生的短路电动力大大高于普通电缆,更容易造成缆体和固定金具的损伤,威胁输配电安全。为了分析高压大截面电缆短路电动力对缆体和金具的影响,文中建立了330 kV高压大截面品型垂直蛇形敷设电缆的电磁—结构耦合有限元模型,使用Maxwell瞬态电磁场分析法计算出电缆的短路电动力体密度分布;采用顺序耦合法将电动力体密度耦合至结构场计算出电缆金具的应力分布;对缆体磁场分布、受力时变特性及金具的应力分布进行了分析。结果表明,缆体短路电动力的幅值随时间周期性衰减 ...

电气化铁路中接触网与受电弓良好的接触是列车安全可靠运行的前提条件,而弓网的接触是载流条件下的摩擦接触,因此有必要对其摩擦接触进行深入研究。文中通过滑动电接触实验机,开展不同工况(压力波动幅度、压力波动频率、接触电流、滑动速度)条件下的弓网滑动电接触摩擦力研究。研究表明:作用于滑板上的接触电流增大时,弓网间的滑动摩擦力随之减小;压力波动幅度和滑动速度增大时,弓网间的摩擦力也随之增大;压力波动频率对弓网摩擦力的影响极小。利用曲线估计的基本思想,优选出最能表达压力波动幅度、接触电流 ...
