摘　　要：结合上海配电网中大截面、大长度的35 kV单芯交联聚乙烯电缆线路的工程实例,在理论计算的基础上,论述了金属护层感应电压和环流在线检测、数据分析以及状态诊断,给出了4套降低电缆线路感应电压和感应环流的合理化抑制方案。Combined with the engineering examples of the large section and long length 35 kV single-core linking polyethylene cables line in Shanghai distribution network,and based on the theoretical calculation,the on-line detection,data analysis and the state diagnosis of the metal sheath induced voltage and circulation were discussed.Four sets of rationalizations restraining schemes for reducing the cables line induced voltage and induced circulation were provided.

关 键 词：金属护层 感应电压 环流 在线检测
