这也是一场同窗兄弟并肩作战创纪录的佳话。带电作业"技术状元"和"±400千伏带电作业第一人"，接力 完成两场带电作业，创造高海拔超高压带电作业的"新高度"，用技术与勇气为雪域高原织就"光明之 网"。 这不仅是高原电网人的胜利，更是我国在极端环境下电网运维技术的里程碑。从"电力天路"到万家灯 火，每一次突破都在为高原的发展注入能量，让光明与温暖跨越海拔，温暖雪域的每一寸土地。 这是一场刷新世界纪录的超高压带电作业。寒冬腊月，国网青海超高压公司输电检修中心的带电作业队 伍，在唐古拉山口海拔5211.5米的高度，开展"电力天路"带电作业，消除±400千伏柴拉直流线路上的缺 陷。 这是一场与时间赛跑的作业。由于唐古拉山口气候变幻莫测，即便晴空万里，正午过后也必起强风，这 一天，这条"电力天路"要完成两场带电作业，而留给他们带电作业的"窗口期"只有上午的3个小时。 ...

危急时刻，内蒙古电力集团乌兰察布供电公司修试管理处变电检修一班接到紧急处置指令：1542刀闸静 触头受极端低温影响发生位置偏移，引发接触不良隐患。若未能及时消除缺陷，极易造成设备发热、异 常乃至故障停运，直接威胁区域电网安全。 近日，乌兰察布地区遭遇强寒潮侵袭，夜间最低气温骤降至零下30摄氏度，极寒天气给电网安全稳定运 行带来严峻考验。在寒风呼啸的德胜变电站内，部分设备因低温出现覆冰现象，电网运维保障压力陡 增。 由于触头表面覆有薄冰，加之作业空间狭窄受限，检修人员必须在极寒中保持高度专注，凭借过硬技术 开展精准调整。凛冽寒风中，防护手套很快被冻得僵硬，指尖逐渐失去知觉，但他们丝毫没有放缓节 奏，凝神聚力、精准操作，用专业与细致攻克每一处技术难点。 经过数小时连续奋战，偏移的静触头成功调整到位，设备隐患彻底消除。当检修人员从高空平安返回地 面时，脸颊、眉梢、睫毛早已凝结起层层白霜，防寒服上覆满冰粒，双手冻得通红僵硬。但看着恢复正 常运行的设备，他们脸上露出了踏实的笑容。 此次极寒条件下的紧急抢修，既是对专业技能的严苛检验，更是对责任担当的生动诠释。面对极端天 气，电力检修人员以无畏坚守迎战风雪，以精湛技术消除 ...

Core Viewpoint - The company is actively implementing the "Forest and Electricity Safety" initiative to enhance the safety of power transmission lines in forested areas, addressing tree-line hazards through collaboration and systematic management [1][2]. Group 1: Initiative Implementation - The company has completed laser point cloud data analysis for tree-line hazards along the 35 kV power line, with recorded distances entered into a hazard database for coordinated management with local forestry authorities [1]. - Since the launch of the "Forest and Electricity Safety" initiative, the company has effectively tackled challenges in cross-regional power grid operations, achieving significant progress in tree-line hazard remediation [1]. Group 2: Hazard Management - The company has identified 91 tree-line hazards through a combination of drone inspections and manual reviews, establishing a dynamic management mechanism for each identified hazard [2]. - A total of 88 tree-line hazards have been addressed, achieving a remediation completion rate of 96.7%, laying a solid foundation for the goal of a "fundamental improvement" within three years [2]. Group 3: Safety Measures and Community Engagement - The company has conducted joint fire emergency drills to enhance collaborative response capabilities to fire incidents, while also increasing public awareness through signage and promotional materials in local communities [2]. - The company plans to deepen the joint patrol mechanism with local forestry workers, ensuring dual protection for power lines and forest fire prevention, while pre-positioning fire-fighting materials in key areas [2].

Core Insights - The Inner Mongolia Power Group Ulanqab Power Supply Company has initiated a special assessment action focusing on the corrosion and fracture issues of the grounding network at the 220 kV Jining Substation to ensure the safe and stable operation of the power grid [1][3] Group 1: Assessment Action - The assessment action utilizes intelligent technology to accurately identify equipment safety hazards, thereby strengthening the protective measures for the regional power grid [1][4] - The grounding network at the Jining Substation is critical for the stable operation of equipment and personnel safety, but it has been affected by soil erosion and climate change, leading to increased grounding resistance and safety risks [3][4] Group 2: Evaluation Methodology - The evaluation includes a comprehensive inspection covering key technical indicators such as overhead line diversion coefficients, contact potential, grounding resistance, step voltage, and soil resistivity [3] - Advanced detection equipment is used to create a topology map of the grounding network, allowing for precise identification of corrosion points and providing a reliable basis for subsequent hazard remediation [4] Group 3: Technological Innovation - The assessment introduces intelligent detection technology based on electromagnetic induction principles, which enhances efficiency by over 70% compared to traditional excavation methods, minimizing disruption to the substation's normal operations [4] - Real-time data analysis and automatic report generation are enabled through an intelligent data analysis system, providing clear insights into hazard locations, severity, and remediation suggestions [4] Group 4: Future Implications - The successful assessment not only addresses the safety issues caused by corrosion but also accumulates practical experience in applying intelligent technology in power grid operations [5] - The company aims to continue promoting the deep application of new technologies and methods in power grid operations, emphasizing a "safety first, prevention-oriented" approach to energy security and public service [5]
