高耸避雷针模型如高架避雷针、电力塔、通信塔存在雷击保护区及散击区。采用电气几何模拟法,并结合实际的雷电监测数据,对避雷针的保护区及散击区半径进行分析和计算。保护区半径随被保护物高度增大而减小,散击区半径随避雷针高度的增加而增加,相对保护效果曲线有一峰值,其对应的避雷针高度即为最佳高度。

Theories and experiments have confirmed that there are protection zone and spread-thundersticke zone exist in models of high lightning conductors like lightning rod ,power towers and signal towers. This paper based on theory of EGM and combined with actual data, calculates and analyzes the radius of protection zone and spread-stricked zone. The conclusion manifestes that the radius of protection zone deminishes while the height of the protected object increases, the radius of the spread-stricked zone rises while the height of the protected object increases, the curve of the relative protection effect has a summit which corresponding the best hight of lightning conductor.
