摘　　要：钻跨一体杆塔是一种能同时实现线路钻越和跨越的新型杆塔,该杆塔目前处于设计阶段但缺乏相应的防雷研究。为了研究不同的防反击措施对110 kV钻跨一体杆塔反击耐雷性能的影响,选取技术经济指标较优的防反击措施,文中采用电磁暂态程序ATP-EMTP仿真计算了110 kV钻跨一体杆塔在两种不同的防反击措施下的反击耐雷水平,比较分析了两种不同的防反击措施的技术经济性。针对钻跨一体杆塔导线布置方式与普通杆塔的不同,文中在计算过程中特别考虑了杆塔竖直导线上感应电压的电磁分量。研究结果表明,增加绝缘子串片数的防反击效果优于安装避雷器的防反击效果,所需经济成本低于安装避雷器,建议选择增加绝缘子串片数作为110 kV钻跨一体杆塔的防反击措施。The drilling and spanning integrated tower is a new type of tower which can achieve simultaneously line drilling and crossing.The tower is presently in the design stage but lacks corresponding lightning protection re-search.For studying the influence of different lightning protection measures on the lightning withstand performance of the 110 kV drilling and spanning integrated tower,the lightning protection measures with better technical and economic index are selected.The electromagnetic transient analysis program ATP-EMTP is adopted in this paper to simulate and calculate lightning withstand level of 110 kV drilling and spanning integrated tower under two differ-ent types of lightning protection measures.The economic and technical performance of the two different types of lightning protection measures are compared and analyzed.In view of the difference between the conductor layout of the drilling and spanning integrated tower and that of the ordinary tower,the electromagnetic component of the in-duced voltage on the vertical conductor of the tower is especially considered in the calculation.The research results show that the lightning protection effect by increasing the number of the insulator strings is better than that by in-stalling lightning arrester,and the economic cost needed is also much lower that of installing lightning arrester.It is therefore suggested selecting the increase of the number of insulator strings as the lightning protection measures of 110 kV drilling and spanning integrated tower.
