无人机为输电线路做“CT” 科技赋能山西临汾电网智慧转型
Zhong Guo Xin Wen Wang· 2025-09-04 11:55
这项技术的突破背后,是临汾电网从"人防"到"技防"的智慧转型。国网临汾供电公司相关负责人表示, 下一步将为这套系统引入AI影像智能诊断——通过建立缺陷样本库,让系统自动识别与预警裂纹、锈 蚀等典型隐患;未来甚至可在临汾域内全覆盖线路、跨区电网及覆冰应力检测等场景中规模化应用,实 现机巢组网、月度自巡,重构"天空地"协同巡检新模式。(完) 而"仿线飞行"则是无人机在自主控制下,通过无人机上毫米波激光雷达,可达到实时、自动、精准地沿 线路飞行,并始终保持与导线、铁塔的最佳观察和作业距离,从而完成拍照、扫描、检测等任务。它将 无人机从一个需要高超技巧手动操控的"相机",变成一个能够自主、精准、重复执行复杂任务的"智能 机器人"。 9月3日,山西临汾,供电人员利用无人机为输电线 路做"CT"。闫永芳 摄 "以前检查线路内部情况,就像蒙着眼睛找人,看不见也看不清。工人必须爬上百米高塔,或者动用大 型机械,不仅风险极高,耗时长,很多隐藏的缺陷发现不了。"该公司输电运检中心副主任杨雪峰说, 如今,无人机仿线飞行技术让巡检发生根本性变革——它能自动复制线路走向,在田间地头复杂环境中 精准保持最佳检测距离,单次飞行即可完成单档 ...
