摘　　要：通过三个问题以及针对每个问题的两种不同答案,对避雷针的离地高度进行了论述。运用作图法阐明了防雷带的作用,指出装了避雷针就可以不装防雷带的观点是错误的。最后通过避雷针保护范围的计算,说明了在重要工程中采用提前放电式避雷针的重要意义。Through three questions and two answers to each question, the height of lightning rod above ground was discussed. The function of lightning bar was illuminated by the graphic method. It was pointed out that the viewpoint of mounting lightning rod without lightning bar was wrong. Finally, based on calculating the protective range of lightning rod, the importance of using early streamer emission lightning rod in important project was explained.

关 键 词：避雷针 防雷带 离地高度 保护范围 提前放电
