悬垂绝缘子串动态风偏响应的数值模拟
Numerical Simulation of Dynamic Response of Suspension Insulator String
【摘要】 针对传统计算方法的不足,采用有限单元法计算分析动态风作用下悬垂绝缘子串的风偏.利用ABAQUS有限元软件计算模拟了500 kV高压输电线路中悬垂绝缘子串在2个典型阵风和脉动风作用下的风偏.计算结果表明,该2种动态风作用下悬垂绝缘子的风偏大于由现有高压输电线路设计规程方法确定的风偏,这可能是近年风偏闪络事故频发的原因之一.
【Abstract】 Finite element method is applied to analyze the windage of suspension insulator strings under dynamic wind loads.The dynamic response of a suspension insulator string of 500kV high voltage transmission line is numerically simulated with ABAQUS software,and results demonstrate that the windage angle of suspension insulator string is larger than that calculated by the conventional design code,which might be one of the main reasons of the frequently happened windage flashover accidents.
