摘要
用计算代替作图法做避雷针保护设计,在分析双针保护曲面特征基础上计算出最低保护高度,从而无需作图亦可选择和校验避雷针。并给出了计算公式,附有例题,可供设计参考。
The design of lightning rods protection is by calculation instead of drawing. The minimum protection altitude can be calculated based on analyzing characteristics of the curved surface of duel rods protection and so it does not need to make drawing to select and calibrate lighting rods. The calculation formula has been presented, attached calculation example as a reference for design.
