21世纪经济报道记者 周潇枭 北京报道 6月5日，国新办举行"新征程上的奋斗者"中外记者见面会，邀请中央企业产业工人代表围 绕"弘扬工匠精神 助力强国建设"与中外记者见面交流。 国家电网山东省电力公司超高压公司输电检修中心输电运维三班班长李敏是受邀出席的代表之一，李敏从事特超高压输电线路 运行检修14年。随着特高压电网大规模投运，线路里程成倍增长，杆塔高度越来越高，各地开始探索无人机应用于输电运检的 新技术新工法。李敏在2017年国家电网无人机巡检技能竞赛中获得个人第三名，并用五年时间斩获山东电力、国家电网、电力 行业、中央企业、全国五级技术能手，实现了本专业技术能手大满贯。 南方财经·21世纪经济报道记者现场提问李敏代表：现在无人机应用越来越广泛，你在把无人机用于输电领域过程中有什么样的 经验可以和大家分享？ （国家电网山东省电力公司超高压公司输电检修中心输电运维三班班长李敏，记者现场拍摄） 李敏回应21世纪经济报道记者提问表示，从2013年开始组建团队探索无人机巡检，那时候确实遇到了很多难题。无人机结构复 杂、操控困难，每天只能巡视3-5基杆塔，有的时候还拍不清、拍不全，曾一度受到质疑。但是他没有放弃，因 ...

"五一"假期将至，为确保辖区居民和企业用电无忧，4月29日，国网福建南平延平区供电公司提前谋划、周密部署， 利用无人机对辖区主要供电线路开展精细化巡视，全力保障节日期间电网安全稳定运行。 ▲供电员工操作无人机进行巡视。雷世凯/摄 此次无人机巡检覆盖了辖区内的重要输电线路、变电站及关键设备。相比传统人工巡检，无人机凭借灵活机动、视角 全面、不受地形限制等优势，能够快速抵达人工难以到达的区域，对线路设备进行高清拍摄和红外测温，精准检测出线 路通道树障、绝缘子破损、线夹发热等潜在隐患。 在10千伏杜溪线巡检过程中，无人机通过红外测温功能，敏锐捕捉到一处耐张线夹温度异常升高的情况。经技术人员 进一步分析，确认是线夹接触不良导致发热，若不及时处理，极有可能引发线路故障，影响周边多个社区的正常供电。 发现隐患后，供电公司迅速组织抢修队伍，对问题线夹进行更换，成功消除了安全隐患。这只是无人机巡检成果的一个 缩影，截至目前，该公司已完成23条主要线路巡检，累计发现并处理隐患3处，确保供电设备 "健康上岗"。 同时，该公司还制定了详细的应急保障预案，安排专人24小时值班值守，确保突发情况能够快速响应、高效处置。下 阶段，该公司 ...
