摘要
针对±500 kV兴安直流线耐张线夹断裂导致导线坠落的故障,提出了4种抢修方案,经过论证确定了最终的抢修方案。现场抢修效果证明,该方案不需要导线备品,不依赖地形条件,只需将故障导线直接牵引回原处进行一次压接操作,减少了拆除间隔棒和将导线放到地面等复杂的抢修工序,方法简单有效,可以显著缩短抢修复电时间。
Aimed at conductor strain clamp fracture faults which caused the fall of conductors in ±500 kV HVDC Xing-an line, four rush-repair schemes are proposed. The final rush-repair scheme is determined by argument. Field rush-repair effects show that the scheme doesn’t need spare conductors or depend on topographic conditions and only needs to drag the fault conductor back to its original position and to execute the crimping operation once, which reduces complex emergency repair procedures such as removing spacers and putting the conductor on the ground and so on. the method is simple and effective which can significantly shorten the time of rush-repair.
