接触网可视化接地系统闭锁关系探讨

Discussion on Locking Relations of Visual Earthing System of OCS

从接触网可视化接地系统的构成入手,阐述城市轨道交通正线供电分段的运行场景和设备编号原则,分析各种运行场景下接地刀闸的闭锁逻辑关系,并对逻辑闭锁方式和越区供电情况下的闭锁设计提出建议,对可视化接地系统设计进行总结,为新线可视化接地系统设计提供参考。

Starting from the composition of the visual earthing system of OCS,the paper illustrates the operation scenarios and equipment numbering principles of the power supply segments of mainline,analyzes the locking logic relation of the earthing knife switches under various operation scenarios,puts forward proposals on the logical locking method and locking design under over-zone power supply.The design of the visual earthing system is summarized,providing reference for the design of the visual earthing systems of the new lines.
