摘　　要：采用串行技术实现一次设备采集是近年电站建设领域的一项新技术 ,从天广直流工程的实践出发 ,介绍了西门子的混合光学直流测量系统的构造和特点。西门子的混合光学直流测量系统由传感头、就地变换器Optodyn、光信号接受装置SymadynD/IO3模块构成 ,就地变换器与光信号接收装置之间采用混合光缆连接 。Acquisition of primary device information with serial communication is a new technique in power station construction.Based on the practice of Tian Guang HVDC project, the structure and features of Siemens hybrid optic measurement system is introduced, which consists of primary sensor, local digitalization unit Optodyn and optical signal receiver Symadyn D/IO3. The hybrid optical fiber is applied between Optodyn and Symadyn, and it completely solves the problem of electric isolation between primary and secondary devices.
