摘　　要：海底观测网的供电具有长期、连续、远距离的特点,采用单极直流输电方案成为一种趋势。单极直流输电采用光电复合缆中的一根铜线和海水作为输电回路,既节约了成本又减少了输电回路的损耗。文中分析了单极直流输电模式中海水作为输电回路的关键技术,通过实验验证了海水回路电阻的主要影响因素,并分析了海水作为输电回路对海洋环境、人类、海洋生命安全的影响。With the seafloor observatory networks long-term,continuous,long-distance power supply characteristics,the adoption of monopolar direct current（DC）transmission mode has become a trend.The use of a length of copper wire of transmission from optic/electric composite cable and the seawater as transmission circuit mode has reduced not only the cost but also the transmission loop loss.The key technology of the seawater as a conductor in monopolar DC transmission mode is analyzed.The main influencing factors of seawater loop resistance are verified by experiment.The potential effect of seawater as a conductor on the marine environment,marine life and human security are dealt with.
