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.
