| 摘 要： | 统计了江苏电网1988～2006年雷电日及2004～2006年架空输电线路雷击跳闸率。杆塔高度增加及复合绝缘子和瓷长棒型绝缘子绝缘强度较低是江苏电网雷击跳闸的主要原因。最后介绍了江苏采用的输电线路防雷措施。

| Abstract: | This paper firstly counts lightning day from 1988 to 2006 and lightning flashover rate of overhead transmission lines from 2004 to 2006 in Jiangsu Power Grid.The main reasons of lightning flashover are increase of tower height and lower insulation strength of composite insulator and porcelain long-rod insulator.Finally some anti-lightning-flashover measures in Jiangsu are introduced. |
