摘　　要：本文通过对末端回路短路电流的计算、分析,计算出不同的保护开关与常用末端线路导线配合时,满足灵敏度要求的配电距离,并进一步阐述在多级配电系统中,上级导线及系统对末端线路的影响,列表得出满足灵敏度要求的末端线路的配电距离。The chief aim of the present study is to find out the distribution distance which can meet the requirements of the sensitivity when different protection switch and common end line wire work together by calculating and analysing the end loop short circuit current. It further elaborates the influence of the system and conductor on end line in a multistage distribution system, and lists the distribution distance of the end of the line that meets sensitivity requirement.
