| 摘 要： | 本文对影响变电所直击雷保护效果的因素作了分析,提出以“失效危险率”或“无危险年限”作为评价指标。应用文中推荐的公式对实例计算的结果表明,避雷线的保护效果比避雷针的好,这与运行经验基本相符。

| Abstract: | The factors influencing the protection effect of direct lightning strokes uponthe substation are analyzed and the"risk rate of failure" or "limit of non-risk years"are proposed as the evaluation index in the article. It is shown by the calculated resultsof the actual examples using the formulas described in the paper the protection effectof overhead ground wire is more efficient than that of the lightning rot.This conclusionis conformed to the operation experiences. |
