摘要
不同的电力线路防雷的观念,直接影响到可采取的防雷措施。分析了在传统的电力线路防雷观念下所采取的防雷措施存在的不足及其原因,阐述了"雷电先导放电临界击距和暴露弧"这一观念对电力线路防雷的重要影响,提出了相应的对传统防雷措施的改进方案。
Various conception of the electric power line lightning protection could affect the selection of the lightning protection measures. This paper analyzes the deficiencies and their causes of the lightning protection measures in the traditional conception of the electric power line lightning protection, describes the conception ＂critical striking distance and exposure arc of the lightning pilot discharge＂ that has the important influence on the electric power line lightning protection, presents the corresponding solutions to improve the traditional lightning protection measures.
