输电带电作业，被誉为"在刀尖上跳舞"，是与高压电流"零距离"的对话，是对技术、意 志和胆魄的极限考验。而张萌与程建勇，这对老兵搭档，便是这片高空战场上最锋利的两 把"利剑"。 2001年带着"优秀士兵"荣誉退伍的张萌，将军人特有的精准、沉稳和勇敢发挥到极致。 每一次攀上几十米高塔，他都心细如发、稳如泰山。"带电作业，就是与虎谋皮，容不得半 分差池。"这是他常挂嘴边的话。而如今他已在电力战线上奋斗了二十余载，从最年轻的班 员到技术精湛的班长，张萌把军人特有的精准、沉稳和勇敢，发挥到了极致。 有一种担当，转换战场，初心不改。它曾回响在军旗猎猎的演训场，如今，它熔铸于纵 横陇原的铁塔银线。 在国网白银供电公司，有这样一支队伍——输电运检中心的34名复转军人群体。他们曾 是制导雷达连操作员、是通信尖兵、是海岸线上的狙击手、是火场逆行的消防勇士……如 今，他们坚守一线，岗位建功。退伍不褪色，换装不换心，当脱下"迷彩绿"，换上"国网 绿"，改变的，是奋战的领域和岗位；不变的，是为人民服务的忠诚与担当。 高空"利剑"的忠诚与传承 与张萌并肩的，是曾在部队服役并荣获集体三等功的程建勇。1997年，他退伍转业至输 电运检中心， ...

Core Viewpoint - The application of drone technology in power transmission inspection has significantly improved efficiency and safety, transitioning from manual to automated processes in the industry [1][3][4]. Group 1: Drone Technology Development - The team began exploring drone inspections in 2013, facing challenges such as complex structures and operational difficulties, initially achieving only 3-5 tower inspections per day [3]. - After several years of development, the drone inspection capabilities improved, allowing for the completion of inspections of 10 towers in half an hour, replacing manual inspections [3]. Group 2: Innovations in Drone Inspection - The team developed three key innovations: an autonomous navigation system for drones, a multi-spectral imaging system for defect detection, and an intelligent analysis system that achieves over 95% accuracy in identifying defects from inspection images [3][4]. - In 2021, the team deployed the first drone nest for autonomous inspections, enabling remote control of drones over distances of up to 4 kilometers without human intervention [4]. Group 3: Achievements and Future Prospects - By 2023, the team established 568 drone nests across the province, creating a collaborative inspection demonstration area and normalizing the use of drone inspections [4]. - The evolution of drone inspections has progressed from manual control (1.0) to autonomous inspections (2.0) and finally to collaborative drone nests (3.0), marking a significant transformation in the industry [4].

Core Viewpoint - The company is proactively ensuring stable electricity supply during the upcoming May Day holiday by utilizing drone technology for detailed inspections of power lines and equipment [1][4]. Group 1: Drone Inspection Implementation - The drone inspections cover important transmission lines, substations, and key equipment within the jurisdiction [4]. - Compared to traditional manual inspections, drones offer advantages such as flexibility, comprehensive perspectives, and the ability to reach difficult terrains, allowing for high-definition imaging and infrared temperature measurement [4]. Group 2: Detection and Response to Hazards - During the inspection of the 10 kV Duxi line, the drone detected an abnormal temperature increase in a tension clamp, which was later confirmed to be due to poor contact [4]. - The company quickly organized a repair team to replace the problematic clamp, successfully eliminating the safety hazard [4]. - To date, the company has completed inspections of 23 major lines and identified and addressed 3 hazards, ensuring the equipment is "healthy" for operation [4]. Group 3: Emergency Preparedness and Future Plans - The company has developed a detailed emergency response plan and assigned personnel for 24-hour monitoring to ensure quick and efficient handling of any unexpected situations [4]. - Moving forward, the company plans to increase inspection efforts and leverage the advantages of drone technology to create a safe, stable, and reliable electricity environment for users during the holiday [4].
