摘　　要：模拟试验表明:目前大量使用的接闪器为—根针的避雷针,其引雷效果并非最佳。当接闪器的针数达到一定值时,其引雷效果明显改善。当伞状导体消雷器针数处于某一值时,其电晕电流最大,当然其消雷效果也应最好。这样就把有良好接地性能的伞状导体消雷器与避雷针统一了起来,同时达到了最佳消雷器和最佳避雷针的性能。At the present time, most of the lighting receivers in use are one-needle lightning rod whose lightning channeling effect are proved not optimal by simulation experiment, when the number of the needle of the lightning receiver reaches a certain value, the lightning channeling effect will be obviously improved, when the number of the needle of the umbrella - shaped conductor lightning eliminator reaches the same value of the lightning receivers as said before, its corona current also reaches the highest, which means that the lightning elimination effect will be the best. So the lightning eliminator and the lightning rod are united and the performance of the optimal lightning eliminator and the optimal lightning rod is reached at the same time. Here the lightning eliminator refers to the well - grounding umbrella - shaped conductor lightning eliminator.
