摘　　要：近些年直升机巡视作业作为一项新的输电线路维护手段已经在国内大范围推广应用,但其作业方式与传统的人工巡视方式在巡视位置和巡视设备等方面存在诸多差异。以直升机和人工巡视同期发现的缺陷为样本,从缺陷位置、发现率和威胁度等方面进行了细致的统计分析。总结出直升机巡视和人工巡视各自的优势,并结合平原和山区的不同地形线路探讨了因地制宜的巡视方式,分析了线路健康水平和经济性这2个制约直升机巡视频度的因素,对以后的深入分析提供了思路。Recently helicopter patrol operation as a new electric transmission line running maintenance way is popularized widely in domestic large-scale area. But its work mode is so different with the treditional manual patrol on the aspects of patrol position and equipment. Using the defections as a sample, which were found by the helicopter patrol and manual patrol, and the particular statistical analysis is based on the aspects of defection position, the discovery rate and the threat value. Their advantages and disadvantages were summarized, and the proper patrol mode adapted to local conditions such as plain or mountain area was discussed. In addition, health level of transmission line and economy these two factors confining the helicopter patrol frequency were also analyzed, which provided atrain of thought forfurther research.
