摘要
对一起220 kV耐张塔引流线断裂故障进行分析,包括对断裂导线外观检查、导线材料性能检测、现场运行环境分析等,得出微风振动是造成导线断裂的主要原因,而故障发生时的大风加剧了断裂过程。针对此次故障,给出了具体的改造方案。
The fracture fault of 220 k V tension-resistant tower drainage line was analyzed,including the appearance inspection of the fractured line,the testing of the conductor material property,and the analysis of the field operation environment,etc. It was concluded that the breeze vibration was the main cause of the line’s fracture,while the strong wind aggravated the fracture process. In view of this fault,the specific engineering modification scheme and preventing suggestion were proposed.
