一种实用型海底光缆传输网络供电系统

Practical power supply system for submarine optical cable transmission network

针对长距离有中继海底光缆传输网络供电难度大和要求高的严峻形势,提出了一种实用型的供电方案。该方案利用岸基电源设备为海底光缆系统提供高压恒流电,在海底光缆不同的距离段设有取电模块,取电模块将高压恒流电转换成稳定的低压直流电,供水下用电设备使用。

According to the difficulty and high demand of supplying power for submarine optical cable trans- mission network, the paper put forward a practical power supply scheme. The scheme use shore power supply equipment to supply high voltage constant current for OFSCS. Electric power modules that placed at different positions of submarine optical cablecan convert high voltage constant current to low voltage constant current, and then transport it to underwater electric equipment.
