摘要
以改造城乡配电网自动化系统为例,阐述了在系统主干线通道上采用光纤通信、分支通信采用屏蔽双绞线RS-485的模式。该设计方案具有节能降耗、环保、可靠的特点,并有利于配电自动化系统建设分期投入、分步实施、信息共享。
Upon the reform of automatic system of urban distribution network, it introduces that a RS - 485 screened twisted - pair wire has been adopted in optic - fiber communication and branch communication for trunk line of the system. Scheme of the design fully shows the characteristics of energy conservation or less consumption, encironmental protection and reliability and militates for the construction of automatic electric power distribution system phase by phase, for the implementation by steps and for sharing together of information.
