摘要:
配电网改造和配电网自动化系统建设的目的在于提高系统的可靠性,配电网接线方式的选择是提高配电系统可靠性的前提和重要基础。首先,介绍了配电网接线方式的选择原则,接着从经济性、可靠性、灵活性等方面对城市中压配电网络的常用接线方式进行了分析比较,如架空线路接线方式、电缆线路接线方式、架空线路和电缆线路混合接线方式,根据不同情况推荐了适用的电网接线方式。

Abstract:
The aim of reforming the distribution network and constructing the distribution auto-mation system is to improve the reliability of the distribution system.The selection of the electric network connection mode is the precondition and groundwork for improving the reliability of the distribution system.Rules of connection mode selection for the distribution network are introduced.With the view of economy,reliability and flexibility,commonly used connection modes of the urban middle voltage distribution network are comparatively analyzed,such as the overhead line,the cable and their mixture.Practical modes for different applications are recommended.
Key words:  middle voltage distribution network,connection mode,economy,reliability
