摘　　要：本文通过对化工户外装置区排放设施的特殊性、雷击风险和防雷现状分析,提出直击雷防护设计步骤,并对接闪器保护范围计算的两种电气-几何模型进行对比和分析,从而得出一个结论,即先导传播模型理论对化工户外排放设施的直击雷保护范围计算更加有效可靠。另外,还通过借鉴电力线路保护角的几何计算法,给出保护范围的作图法。In this paper,the particularity of discharge facilities,lightning risks and status of lightning protection in the chemical outdoor equipment area is analyzed,and the design step of direct lightning protection is proposed.The two electrical-geometric models for calculating the air-termination system protection range are compared and analyzed,thus a conclusion is drawn.That is,leader propagation model is more effective and reliable for the calculation of the direct lightning protection range of chemical outdoor discharge facilities.In addition,by learning from the geometric calculation of the power line protection angle,a method of drawing protection range is given.
