绍如何利用波的概念来研究分布 参数回路的过渡过程,从而得出导线在冲击电压作 用下电流压的变化规律,确定过电压的最大值。
This chapter will be focused on how to use the concepts of wave to study the transition process of distributed parameter loop. Thus the variation of current and voltage of the wire under the effect of impulse voltage can be drawn to figure out the maximum overvoltage.
第7章 输电线路和绕组中的波过程
Chapter 7 Wave-process of transmission lines and windings
在电力系统正常工作下,输电线路、母线、电缆以 及变压器和电机的绕组等元件,由于其尺寸远小于50Hz 交流电的波长,故可以按集中参数元件处理。
Under the normal condition of power systems, the components such as transmission lines, generatrix, cables, windings of transformers, etc can be considered as lumped-parameter elements because their sizes are far less than the wavelength of AC mode(50 Hz).
