%X 电能是现代社会应用最广泛的能源之一，输电线路上的覆冰、风筝、塑料薄膜等各类障碍物，对电网的安全稳定运行造成了巨大的威胁。激光能够远距离、无接触地快速清除障碍物，并且能够实现带电作业，有着广阔的发展前景。本文主要研究了激光参数对于除障效果的影响。首先，以两种典型障碍物，覆冰与塑料薄膜为例，分析了不同波长激光对不同类型障碍物的吸收与热熔效果。其次，通过实验确定了熔穿塑料薄膜与有效切割透明薄膜所需的最小功率密度。接下来，对比了激光输出模式的不同对除障效果的影响。还测量了激光除障中不同类型绝缘子损伤阈值数据，研究了大气环境对于激光除障的影响。最后，还介绍了已研发的不同类型的激光除障装置样机。<br />
Electricity is one of the most widely used energy sources in modern society. Ice, kites, plastic films and other types of barriers on transmission lines pose a huge threat to the safe and stable operation of the power grid. Laser technology has a broad development prospect as it can remove barriers contactless over long distances without power outage. Firstly, the absorption and thermal melting effects of different wavelengths of laser on different types of barriers are analyzed, using two typical barriers, ice and plastic film, as examples. Secondly, the minimum power density required to melt through and effectively cut transparent plastic film is also determined experimentally. Next, the influence of different laser output modes on the efficiency of barrier removal is compared. The damage thresholds for different types of insulators in laser barrier removal are studied by experiment measurement and the effect of atmospheric conditions on laser barrier removal is also investigated. Finally, different types of laser barrier removal device prototypes which have been developed are also presented.
