（来源：经济日报） 据了解，此次开展5211.5米海拔带电作业，是我国首次在5000米级高海拔区域开展超高压等电位带电作 业。电网技术人员在高海拔地区、极端环境下的带电作业，意味着电网运维拥有了更安全、更高效、更 可靠的技术手段，最大程度减少停电时间，为当地经济社会发展和民生保障提供更加坚强的电力支撑。 （经济日报记者 石晶） 转自：经济日报 2月6日，国网青海省电力公司运维检修人员在唐古拉山口附近5211.5米海拔处，成功开展等电位带电作 业，消除青藏联网工程±400千伏柴拉直流线路上的缺陷，为保障西藏地区春节期间电力稳供筑牢安全 防线。 ±400千伏青藏联网工程是我国首条进入西藏的"电力天路"，作为连接青藏的能源大动脉，该工程于2011 年底建成投运，西藏电网成功实现与国家大电网互联互通，西藏地区冬季缺电和夏季水电消纳难的矛盾 自此得到解决。其中，柴达木换流站至拉萨换流站直流段工程平均海拔4650米，穿越多年冻土，线路运 行维护难度极大。 "当前西藏地区正处于节前用电高峰期，带电运维解决了出现的问题，还保障了供电不中断。"国网青海 超高压公司"唐古拉之鹰"电力天路运维班安全员应洪告诉记者，春节前该公司组织 ...

Core Viewpoint - The successful completion of live working at an altitude of 5211.5 meters by the State Grid Qinghai Electric Power Company marks a new world record for ultra-high voltage live working at high altitudes, enhancing the safety and reliability of power supply in Tibet during the peak electricity demand period [1][2] Group 1: Project Overview - The ±400 kV Qinghai-Tibet interconnected project, known as the "Electricity Highway," is the first power line to enter Tibet, completed and put into operation at the end of 2011, enabling the integration of the Tibet power grid with the national grid [1] - The project addresses the seasonal electricity shortages in winter and the challenges of hydropower consumption in summer for the Tibet region [1] Group 2: Operational Achievements - The live working operation was conducted at two locations: the 1382 tower near the Tangula Mountain Pass at 5211.5 meters and the 1134 tower in the Yanshiping area at 4691 meters, both setting new world records for altitude [2] - The operation demonstrates the advanced capabilities of the power grid maintenance in extreme environments, ensuring minimal power outages and providing robust support for local economic and social development [2] Group 3: Safety Measures - The company utilized drones for comprehensive inspections of the power line, identifying and addressing potential hazards before the peak demand period, ensuring a stable power supply for the Tibetan people during the Spring Festival [2]

Core Viewpoint - The State Grid Corporation of China has successfully conducted the first high-altitude live working operation at an elevation of 5,211.5 meters, setting a new world record for ultra-high voltage live working at high altitudes [1][2] Group 1: Project Details - The operation took place near the Tangula Mountain Pass, specifically at tower 1382, which is at an elevation of 5,211.5 meters, and another operation was conducted at tower 1134 in the Yanshiping area at 4,691 meters, both setting new world records [2] - This operation is part of the ±400 kV Qinghai-Tibet interconnection project, which is China's first "electricity highway" into Tibet, completed in late 2011, enabling the integration of the Tibet power grid with the national grid [1] Group 2: Operational Significance - The Qinghai-Tibet interconnection project addresses the seasonal electricity shortages in Tibet, particularly during winter, and the challenges of hydropower consumption in summer [1] - The average elevation of the Chaila DC segment of the project is 4,650 meters, and it traverses permafrost, making maintenance operations extremely challenging [1] Group 3: Safety and Reliability - The operation is crucial as Tibet is currently experiencing peak electricity demand, and any minor issues could escalate into significant problems [1]
