北京地区 10 kV 配电网架空线路自环互联式接线研究分析

Ｒesearch and Analysis on Self － ring Inter － connection Mode for 10 kV Overhead Line of Beijing Distribution Network

摘要:

:针对 10 kV 架空线路普遍采用的树枝式、单电源单环、双电源单环、三电源单环以及分段多联络等传统网络结 构进行了研究分析，阐述了它们存在的共性问题，并在此基础上针对性地提出了自环互联式接线方式，从方式灵活 性、供电可靠性、异常方式影响以及负载率等方面论证了此种接线方式的优势，为北京地区 10 kV 架空线路规划与改 造提供了一种较为科学的参考方案。

Abstract:

The traditional network structures such as single power branch，single － supply single ring，double － supply single ring，three － supply single ring and multi － segment with multi － contact and so on adopted widely in 10 kV overhead lines are analyzed，and the common problems are explained． On this basis，self － ring inter － connection mode is proposed accordingly． The advantages of this kind of connection mode are demonstrated from the flexibility，power supply reliability，influence of abnormal mode，load rate and so on，which provides a more scientific reference scheme for the planning and reform of 10 kV overhead lines in Beijing．
