摘　　要：针对近年来输电线路风偏闪络事故频繁发生的现状,为降低风偏闪络的发生几率,本文分析了现有绝缘子串风偏角计算模型。对于目前模型存在的问题,从输电线应力变化方面考虑,通过受力分析,提出一种新的绝缘子风偏角计算模型,进一步研究对最小空气间隙的影响。利用matlab编程计算结果并对比分析,在一定程度上减小现有模型的误差,为高压输电线路防风偏设计和研究提供参考和理论依据。According to situation of the accidents caused by windage yaw occurred in recent years,to reduce the probability of windage yaw flashover,the article analyzes the existing computation model of windage yaw flashover for Insulator string.For model＇s defects,the article provides a new computation model of windage yaw flashover through the stress analysis and simulate by matlab considering stress＇s Real-time changes to research the influence of the minimum air space.Finally,it conducts contrast analysis,which provides some useful references and theoretical basis for HV transmission.
