摘要
减少输电线路雷击跳闸率一直是电力工程技术人员关注的课题,对于雷电活动强烈、土壤电阻率高、地形复杂的山区线路,采用常规的措施降低雷击跳闸率已难以奏效。实践表明,采用线路避雷器是有效的防雷措施之一。重点介绍110kV带串联间隙线路型复合外套氧化锌避雷器的保护原理、技术参数和组装工艺要求。
The reduction of line lightning trip-out rate becomes a topic of common concern. Using conventional measures to reduce the lightning trip-out rate is unlikely to be effective for transmission lines in the complex terrain mountain with strong lightning activity and high soil resistivity. Domestic and international practices show that use of line surge arresters is the most effective lightning protection measure. This article highlights 110 kV polymeric housed line MOA with supporting series gap.
