摘要
架空输电线路覆冰会使绝缘子绝缘性能大幅度降低,严重时可导致线路掉闸,同时存在倒塔断线的风险,威胁主网安全稳定运行。在分析现有除冰方式及装置优缺点的基础上,详细阐述了除冰专用跟头滑车的研制过程,并结合实际进行现场试验。试验结果表明,除冰专用跟头滑车降低了作业风险,提高了作业效率,具有一定的推广及应用价值。
Ice coating on overhead transmission lines would greatly reduce the insulation performance of insulators and even lead to line tripping as well as the hazards of tower collapse and line breaks,which threatens the safe and stable operation of the main grids.By analyzing the pros and cons of the existing de-icing methods and devices,the development process of special de-icing somersault pulleys is specified together with field tests combined with reality.The tests show that the special de-icing somersault pulleys reduce operation risks and improve operation efficiency with certain promotion and application prospects.
