“ijzz”重庆开展雨雪冰ijzz冻灾害实战化联动应急演练 首次运用直升机整体组立抢修塔

  为进ijzz一步强化防范和应对自然灾ijzz害的能力,提高应对雨雪冰冻灾害的能力,近日,国网重庆市电力公司在重庆武隆开展雨雪冰冻灾害实战化联动应急演练。

  本次演练重点检验了全地形、大载重无人机、直升机“空地结合、高低搭配”的抢修模式。其中,直升机整体组立三柱式应急抢修塔这一作业技术为重庆首次应用,填补了重庆在中型直升机组塔作业方面的技术空白,为极端情况下快速复电提供了新思路、新方法。

  演练现场,直升机把重1.5吨,长21米,截面只有0.9米的立柱式抢修塔稳稳立在1平方米的地面上,不但要克服结构细长、风荷载导致的操控难度,还要对抗超低气温、紊乱气流ijzz带来的不稳定性,构件姿态极难控制,抢修塔组立难度不亚于“在钢丝上跳舞”。

  三柱式应急抢修塔具备重量轻、结构简单、拉线承力的特点和无基础施工的优势,避免了漫长的基础施工周期,可以极大提高抢修效率。也正因为没有基础,直升机整体吊装难度大幅提高。
