文章基于海南联网工程500kV海底电缆(以下简称“500kV海底电缆”)机械保护方式受海洋水文、气候、地质环境影响所产生的变化和500kV海底电缆长期面临的外力破坏风险,通过国内外水下管线检测设备及技术在500kV海底电缆运维工作中实际应用的研究,梳理整合检测设备和检测技术的工作原理及工程实际检测成果,最终形成一套500kV海底电缆路由检测技术体系,用于指导500kV海底电缆定期检测工作的开展,提高500kV海底电缆外力破坏防护能力。
The article is based on the changes of mechanical protection mode of Hainan 500kV submarine cable (hereinafter referred to as “500kV submarine cable”) affected by marine hydrology, climate and geological environment and the long-term risk of external damage to 500kV submarine cable. Under the pipeline testing equipment and technology in 500kV submarine cable operation and maintenance of practical application research, combing the integration of testing equipment and testing technology works and the actual test results, and ultimately form a set of 500kV submarine cable routing detection technology system for guidance 500kV submarine cable to carry out regular testing work to improve the 500kV submarine cable external damage protection.
