Abstract:
In order to study the dynamic response of high voltage transmission lines with drum type towers under mechanical faults of insulators, the non-linear dynamic finite element model of AC(alternating current)high voltage transmission line system, including transmission tower, transmission line and insulator, was established. The transient dynamic analysis method is proposed to analyze the variation law of dynamic response under insulator rupture, and the dynamic response of structural elements next to the broken span is calculated. The results show that the peak tension in the conductor of the upper crossarm at the suspension point exceeds the design value.Insulator rupture has no effect on the tower components of the upper crossarm, but it has a significant influence on the insulator tension of the upper crossarm.
