OPPC在宜春35kV三阳—柏木送电线路中的应用

The application of OPPC on 35 kV Sanyang-Bomu transmission line in Yichun

目前,我国35kV及以下线路一般采用三相电力系统传输,大多都没有地线,系统的电力通信采用传统的方式进行。若用光纤复合相线替代三相电力线路中的1相,形成由2根导线和1根光纤复合相线的电力传输系统,故可不另架设通信线路以解决电网的自动化、调度、通信等问题,还可大大提高传输的质量和数量。结合工程实际,介绍了光纤复合相线在江西宜春袁州区35kV送电线路的应用情况。

The three-phase power system transmission is generally applied on the existing power line up to 35 kV without an earth wire, and its telecommunication is achieved through the traditional way. If we replace one of the three phases with Optical Phase Conductor/OPPC） to build a power transmission system of two conductors and one OPPC, An easy solution is proposed to the problems of power automation, dispatching and telecommunication of this kind of power grid. to greatly improve the quality and quantity of transmission without additional installation of telecommunication lines. This article introduces the application condition of OPPC on Sanyang-Bomu transmission line in Yuanzhou area, Yichun, Jiangxi, combining the engineering practice.
