Abstract:

In order to study the dynamic response of high-voltage transmission lines under mechanical failure, a finite element model of a domestic 500-kV high-voltage transmission line system is established.The initial equilibrium condition of the coupling system model is verified by nonlinear static analysis.The transient dynamic analysis method is proposed to analyze the variation law of dynamic response under cable or insulator rupture, and the dynamic response of structural elements next to the broken span is calculated.The results show that upper crossarm cable rupture has no effect on cable tension at adjacent suspension points, but it has a significant influence on tension in the insulator and the tower component of the upper crossarm next to the broken span.The peak tension in the conductor of the upper crossarm at the suspension point exceeds the design value under insulator rupture.Insulator rupture has no effect on the tower component of the upper crossarm, but it has a significant influence on insulator tension of the upper crossarm.Insulator rupture should be taken into account in the design of overhead transmission lines.The research results can provide a theoretical basis for the design of transmission lines.
