摘要
经济快速发展,大量高压输电线采取跨越林区的方式走线,由此带来森林火灾隐患。当前不少研究聚焦于森林火灾对输电线路造成的潜在影响,但忽略了输电线路自身所带来的火灾隐患。文章通过介绍当前的输电线路森林火灾风险评估及区划研究,分析输电线路中的卫星遥感、激光雷达、无线传感监测技术的优缺点及其应用现状,为输电线路的设计者和施工人员提供降低输电线路引发森林火灾隐患的新思路。文章还认为现有的研究大多集中于输电线路森林火灾的在线监测及预警,今后应聚焦架空输电线路森林防火设计及施工措施研究,提升输电线路的灾前防范能力。
With the rapid development of economy,a large number of high-voltage power transmission lines were routed across the forest,which brought the fire risks of forest fire.Now,many current studies focused on the potential impact of forest fires on transmission lines,but they ignore the fire hazards caused by transmission lines themselves.By introducing the current forest fire risk assessment and zoning research of transmission lines,the paper analyzed the advantages and disadvantages of satellite remote sensing,laser radar and wireless sensor monitoring technologies in transmission lines and their application status,so as to provide a new idea for transmission line designers and construction personnel to reduce the forest fire risk caused by transmission lines.It was also considered that most of the existing research focused on the online monitoring and early warning of forest fires on transmission lines,and the research on forest fire prevention design and construction measures of overhead transmission lines should be focused in the future to improve the pre-disaster prevention ability of transmission lines.
