“三段电流保护”实验电路设计与实现

Designing and Performing the Experiment—“Three Sect Current Protection”

开发设计了一套实验电路并制作了实验柜,使实验过程接近于实际的保护装置动作过程,对深刻理解“三段电流保护”的整定、配合,进一步领会继电保护的可靠性、选择性有较好作用。

We developed and designed a set of experiment circuit and cabinets. This circuit makes the experiment alike to the practical action process of protection device, which is helpful for profound understanding of the three sect current protection so as to deeply comprehend the reliability and selectivity of relay protection.
