摘要
由于海底电缆独有的结构特性和复杂的敷设环境,其金属护套和铠装环流问题一直是研究的重点。本文结合实际运行的110kV海底电缆环流故障案例,深入分析其产生的原因,并且根据实际地理环境等因素,研究出一套降低海底电缆环流的改造方案。
Due to the unique structural characteristics and complicated laying environment of submarine cables, the problem of metal sheath and armor circulation has been the focus of research. Combining with the actual operation of 110 kv cable circulation failure cases, in-depth analysis of the reasons, and according to the practical factors such as geographical environment, developed a set of lower submarine cables with the retrofit scheme of circulation.
