摘　　要：简述了山火条件下对输电线路闪络机理展开研究的必要性。介绍了山火灾害影响因素,总结了山火条件下架空输电线路闪络机理的研究现状,包括对现有试验方法进行分析探讨,接着综述了目前应用于输电线路的山火监测方法及其存在的问题,提出激光雷达应用于输电线路山火监测的新思路,同时指出,卫星遥感技术和传统传感器终端监测方法相结合,能提高输电线路监测的可靠性和实时性。The necessity of the study on flashover mechanism of overhead transmission lines under forest fires has been introduced in this paper. Fire disaster influence factors are introduced,and the research status of flashover mechanism of Overhead Transmission Lines under Forest Fires has been summarized,including the analysis and discussion of the existing test methods. Then,the present methods to monitor forest fires applied in transmission lines and its existing problems are summarized as well,and a new idea that Laser radar technology is adopted in transmission lines to moni-tor forest fires has been proposed. Meanwhile,it has been indicated that the combining of Satellite remote sensing technology with traditional sensor terminal monitoring methods will improve the reliability and real-time of transmis-sion line monitoring.
