随着大庆保电任务圆满收官，9月起，国网西藏电力运检工作重心正式切换至秋检预试 阶段。此次秋检周期将持续至11月底，涉及487项检修预试任务，投入作业人员超2700人。 国网西藏电力面对阿里联网、川藏联网等重要跨省跨区断面轮流检修、Ⅲ级作业与五级 及以上电网风险交织、技改大修与配网基建攻坚叠加的多重挑战，公司提前谋划、精准部 署，以全方位举措压实安全责任，全力护航电网平稳运行，为迎峰度冬筑牢坚实屏障。 ▲8月31日，国网昌都供电公司输电运检中心四郎珠扎和贡秋正在对35千伏俄曲线开展 秋季运维检修工作。巴桑次仁/摄 ▲8月31日，国网琼结县供电公司近期全面开展线路秋检工作。 完成柴拉直流14处净空距离不足隐患治理；10月底前完成163项蓄电池组更换及9条风偏、覆 冰雪隐患线路整治；12月底前攻克27条频跳线路难题。 针对冬季季节特点，国网西藏电力提前布局迎峰度冬准备工作。开展输电线路防漂浮 物、防火特巡，组织林芝、昌都等地完善融冰方案并开展演练；强化变电站防冻保温、消防 设施检查维护，加强充油充气设备油位、压力及渗漏检查；排查电厂水工设施安全，做好机 组维护及蓄水储备；在阿里、那曲等重点区域强化中压发电车应急保障 ...

面对险情，莆田供电公司输电运检中心当即联合国网福建超高压公司商讨消缺方案。考 虑到作业点以及塔型结构限制，双方一致决定采用滑车组荡入作业点进行消缺。该方法所需 工器具较少且轻便，并且能够满足500千伏进入电场过程中组合间隙要求。 7日上午9时许，烈日高悬。近三十层楼高的输电铁塔巍然矗立。两名带电作业人员穿上 屏蔽服，戴上安全帽，系好安全带，开始攀爬。当全副武装的俩人到达铁塔顶部时，汗水早 已湿透全身。无人机红外显示作业人员体表温度达47摄氏度。来不及喘口气，一名作业人员 在高空搭档的帮助下、在地面人员的配合下，"乘坐"软梯荡入电场，顶住强电场对身体的压 迫，将松脱的R销复位并加固，消除了线路的安全隐患。整个过程高效有序，实现消缺"零 感知、零失误"。 此次带电作业有效提高了电网的供电能力和可靠性，为迎峰度夏期间的电力供应提供了 有力保障。未来，莆田供电公司将与国网福建超高压公司深化协作机制，共同探索新技术、 新装备在带电作业现场的应用，共同筑牢莆田电网的安全防线，为莆田地区高质量发展注入 源源不断的电力动能。 ▲带电作业人员将松脱的"R销"复位并加固，消除线路安全隐患。（郑泽楠 摄） 8月7日，国网莆田供电公 ...
