摘要
目前光纤复合架空地线(OPGW)是电力通信网的主要形式,而OPGW尚无有效的融冰手段,OPGW光缆一旦重覆冰后有可能会断裂,从而导致电力通信通道中断,危及电力控制系统的正常运行。文章通过分析OPGW直流融冰的温升过程对光纤、纤膏及整体光单元的影响,得出OPGW融冰过程中光单元合适的控制温度,为地线融冰提供借鉴。
The optical fiber composite overhead ground wire （OPGW） is the main form of electric power communication network, but there are no effective means of melting ice for OPGW, and OPGW cable is likely to fracture once covered by heavy ice, resulting in interruption of power communication channel, and endangering the normal operation of the electric control system. This paper analyses the influence of the temperature rise of OPGW DC melting process of optical fiber, optical fiber cream and whole optical unit, obtains the appropriate control temperature of optical unit in the process of melting ice, and provides reference for ground wire melting ice.
