海底光缆网络岸基恒流供电系统的研究

Research on the Shore-Base Power Feeding Equipment for Submarine Fiber Optic Cable Network

目前长距离海底光缆网络通过岸基供电系统对中继器、监测节点海底有源设备进行供电,为此主要研究使用串联恒流方式供电的岸基供电系统,讨论了岸基供电的要求,介绍了海底光缆供电系统基本结构和原理,及并联运行模块的自动均流原理,最后简要阐述了岸基供电设备的安全要求及维护。

Nowadays long distance submarine fiber optic cable network adopts shore-base power feeding equipment to power the repeaters and detective nodes.It focuses on the shore-base power feeding equipment using power supplying mode of constant current in series.The technical requirements of shore-base power feeding are discussed.The basic structure and principle of the power feeding equipment,and the principle of automatic current adjustment for parallel connection are presented.At last,the safety requirement and the maintenance of the equipment are described briefly.
