摘要
直升机带电检修是在直升机巡线和直升机带电水冲洗的基础上,开发出来的一项新的线路检修作业方法,是一种依据等电位原则,直升机直接或通过吊索把检修人员间接运送到带电的作业点上完成检修任务的方法。其关键点包括直升机的选型、作业方法的研究和工器具的开发。该方法具有高效快捷、作业灵活的优点,并且克服了传统人工带电检修方法受地形因素制约大以及在特殊故障条件下不能实施等缺点,将会大大提高超高压/特高压线路的运行维护水平。
Helicopter live-line overhaul is based on helicopter patrol and helicopter flush technique, and it is developed as a new method for power transmission line overhaul and maintenance according to the equal potential principle. The helicopter sends the maintainer to the work place directly or by using the suspension cable indirectly. The key points are helicopter type selection, the job mode research and the tools exploitation. Except these advantages of high efficiency and flexble performance, compared with the orthodox manual live-line overhaul, this method will be never limited by topographic factor anymore, and can be applied in the special failure condition. It will finally improve EHV/UHV power transmission line operation and maintenance level.
