摘　　要：海底电缆周围环境复杂多变,直接影响海底电缆运行温度,有必要对海底电缆运行温度的变化规律进行分析,结合实际情况更加精确的对海底电缆过负荷能力进行预测。文章从理论角度对影响海底电缆运行温度的各方面进行了分析,并连续统计了8天的海底电缆温度在线监测系统所监测到的温度数据信息,结合海底电缆通过的负荷及电流变化情况、海底电缆埋深、潮汐变化情况,对海底电缆运行温度的规律进行了分析。The surrounding environment of the submarine cable is complicated and changeable, which directly affects the operating temperature of the submarine cable. It is necessary to analyze the change regulation of the submarine cable operating temperature, so as to forecast the overload capacity of the submarine cable with the actual situation. From the theoretical view, various aspects of the submarine cable operating temperature are discussed. And the temperature data from submarine cable temperature on-line monitoring system about 8 days are recorded and researched, combined with the load and current changes, depth and tidal changes, the change regulation about the operating temperature submarine cable are analyzed.
