摘　　要：独立引雷系统广泛应用于多种场合,特别是作为户外场所的雷电防护装置,其将雷电引入自身并泄放至大地,从而保护建筑物、人员或设备免受直接雷击。在独立的引雷系统周边设置相应的防跨步电压措施是十分必要的,但相应的措施能达到怎样的防护效果,目前还有待进一步研究。文章对雷电流入地模型进行了分析,考虑土壤电阻率、雷电流分流系数等影响,得出独立引雷系统雷电流入地点附近跨步电压模型。通过此模型,能够直观有效地分析跨步电压,对指导跨步电压的防护措施有重要价值。Independent mine leading systems are widely used in many situations,especially as lightning protection devices in outdoor places,which introduce lightning into themselves and release it to the ground,thereby protecting buildings,people or equipment from direct lightning strikes.It is very necessary to set the corresponding anti-stepping voltage measures around the independent mine leading system,but the protective effect of the corresponding measures remains to be further studied.In this paper,the model of lightning flow into the ground is analyzed.Considering the influence of soil resistivity and lightning flow shunt coefficient,the model of step voltage near the lightning inflow site of independent lightning leading system is obtained.Through this model,the step voltage can be analyzed directly and effectively,and it is of great value to guide the protection measures of step voltage.
