摘　　要：通过对比分析不同高度避雷针在折线法和滚球法防雷保护范围计算中的保护范围,得出折线法确定的保护范围与滚球半径为3倍避雷针高度的滚球法的保护范围近似相当的结论。By comparing and analyzing the protective ranges of lightning conductor with different heights in the lightning protection ranges of the polygon method and the rolling sphere method,the protective range determined by the polygon method is approximately equal to the protective range of the rolling sphere method with a rolling sphere radius of 3 times the lightning conductor height.

关 键 词：防雷保护 折线法 滚球法
