Comparison Analysis of Testing Methods in Different Standards for AC Submarine Cable System
-
摘要: 国内外适用于交流海底电缆的覆盖6～500 kV电压等级的主要标准和技术文件,随发布时间、适用对象、技术侧重等不同,对于同一试验,各文件中的规定和要求存在一定差异。文中梳理了国内外关于交流海底电缆主要标准和技术文件的制/修订情况及相互联系,阐述了海底电缆系统机械试验、三芯海底电缆电气试验和透水试验等海底电缆系统重点试验项目在不同标准中规定的差异,并给出标准中试验方法制/修订方向的建议。Abstract: Standards and technique documents for AC submarine cables at home and abroad covers the voltage range from 6 kV to 500 kV.There are differences in testing methods and requirements in those documents depending on release date, applicable products, and technical emphasis.Preparation and revision of main standards and technical documents of AC submarine cables at home and abroad and their mutual relations were introduced.Differences of the key test items of submarine cable system, such as mechanical test of submarine cable system, electrical test of three core submarine cables and water penetration test in different standards were expounded.Suggestions on the revision direction of standard test method in the future were also proposed.
