摘要
本文研究了电流在过载情况下信号取样与变化,讨论了反时限电子过流保护装置的工作原理,并比较两种延时整定曲线,进一步探讨了如何限制过载电流。
This paper studies the for sampling and chang in the condition of overurrent,discusses the working principle of electronic inverse time limited overcurrent protector compares two delay renovting curves,approaches further how to restrict the overcrmt.
