非磁性铝合金铠装海缆损耗实验研究

Experimental Study on the Non-Magnetic Aluminum Armored Submarine Cable Loss

基于海洋输电实验基地,对110 kV单芯非磁性铝合金铠装海缆的损耗进行了实验研究。实验验证了当线芯导体通过大电流时,铅护套及铠装上产生了感应电动势,并且在不同运行方式的损耗测试中证明了铅护套具有屏蔽作用。最后通过对比实验,证明了在金属护套与铠装回路中串联电阻能够减小海缆的损耗。

This paper presents an experimental study on the armored loss of the 110 kV single-core submarine cables upon the base of the marine transmission experiment. The results of the experiment showed that when a large current flows through the core conductor, an electromotive force is generated on the lead sheath and the armor and proved that the lead sheath has an shielding effect under different operation patterns. Finally, the comparative test has proved that series resistance in metal shield and armored circuit can reduce the loss of submarine cable.
