摘　　要：为分析引起导线粘连的因素及各种粘连因素的交互作用对导线粘连产生的影响,提出了基于响应面法的导线粘连因素交互作用分析。首先提出覆冰厚度、风速、档距、初始间距4种粘连因素并建立导线粘连数学模型;然后基于MATLAB迭代法,解出各因素在不同组合工况下对应的临界粘连电流值,最后基于方差分析法和响应面分析法,针对不同组合工况下的临界粘连电流值进行数值分析。分析结果表明,初始间距过小、档距过大是引起分裂导线发生粘连的最主要因素;初始间距越小、档距越大,导线越易发生粘连;两者的交互作用对导线粘连的影响极显著。In order to analyze the factors causing the wire adhesion and the influence of the interaction of various adhesion factors on the wire adhesion, the interaction analysis of wire adhesion factors based on response surface method is proposed. Firstly, four adhesion factors including icing thickness, wind speed, span and initial spacing are proposed, and the mathematical model of conductor adhesion is established. Then, based on MATLAB iteration method, the critical adhesion current value of each factor under different combination conditions is solved. Finally, based on variance analysis method and response surface analysis method, the critical adhesion current value under different combination conditions is analyzed numerically. The analysis results show that too small initial spacing and too large span are the main factors causing the adhesion of bundled conductors. The smaller the initial spacing and the larger the span, the more likely the conductors are to adhere. The interaction between the two has a significant impact on the conductor adhesion.
