传统上，我们使用一根置于空气中的金属终端【富兰克林避雷针】和一条与集成的接地装置连在一起的下导线路来保护建筑物。
Traditionally structures have been protected by the use of air terminals (Franklin Lightning Rods) and a network of downconductors connecting to an integrated grounding system.
提高避雷线保护的有效性可以通过减小避雷线—相导线间隙击穿概率来达到。
Effective shielding can be achieved by reducing the breakdown probability of the gap between shielding wire and phase conductor.
应用改进的电气几何模型分析了输电线路杆塔结构、避雷线和导线的布置、雷电流的幅值、地面倾角对绕击率的影响。
With such model the effect of tower structure, lightning current amplitude, angle of the lightning incidence, as well as the ground angle on the shielding failure rate are analyzed.
现如今有一些人使用避雷针，避雷针是一根长长的金属杆。人们把它们高高的放在房子上面，再用一根导线连接到地上。
Today some people use lightning rods. these are long metal poles. people put them high up on the roofs of their houses. a wire runs from the rod down into the ground .
事实上，这样的话闪电就不会击到房子上了，而是通过避雷针再通过导线传到大地。所以呢，闪电就无法造成伤害了。
In fact, now lighting will not hit the house. it hits the rod instead. The lightning goes down the rod and down the wire. it ends up in the ground. here, the lightning can't hurt anything.
