110kV内桥接线智能变电站电流回路配置及相关检修策略

Configuration and Maintenance Strategy of 110kV Inner Bridge Wiring of Current Circuit in Intelligent Substation

通过分析内桥接线形式下智能变电站电流回路配置不同方案,得出不同设计方案的优缺点及检修策略,最后以110kV鹭湖变电站为例,叙述内桥分段电流回路配置特殊性及在鹭湖变电站施工时存在的问题,为内桥接线形式的智能变电站设计和检修提供参考。

The different current circuit configuration schemes of internal bridge wiring in intelligent substation was ana lyzed. The advantages and disadvantages of different design schemes, and the corresponding maintenance strategy were compared. Finally, the llOkV Luhu substation was used as an example, and the particularity of the bridge current circuit configuration and the problems in the construction of Luhu substation were introduced. It provides reference for the design and maintenance of intelligent substation in the form of internal bridge connection.
