摘要
在山坡地区 ,避雷针保护范围计算及作图可应用避雷针保护直接作图法。根据被保护物的高度和其占地面积的大小 ,查表可选择出避雷针的高度和个数 ,并可进行两方案比较 ,然后直接做出防雷保护范围图。一般情况下 。
In mountains area, when calculating and drawing the graph for protection area of lightning rod, we can use the direct graphic method. Based on various heights and the area of protected objects, we can get the height and number of lightning rod by the table, and comparing with the two methods, then the graph of lightning rod protection can be directly drawn. This method is so easy that the conventional complicated calculation, generally, is unnecessary.
