刚体直杆模型计算风偏角的影响因素分析

Analysis of Influence Factors on Computing Wind Deflection Angle with Rigid Body Straight Rod Model

采用刚体直杆模型,计算绝缘子串风偏角,分别研究了水平档距、垂直档距、风速、风向、风压不均匀系数、地形以及加重锤等主要因素对绝缘子风偏特性的影响程度。研究结果表明:水平档距与绝缘子串风偏角呈正相关,垂直档距与绝缘子风偏角呈负相关;在风速一定的情况下,风向的主要影响区间在垂直于线路约±60°区间内。

Rigid body rod model is used to calculate the wind deflection angle of the insulator string, and the influence degree of main factors such as horizontal span, vertical span, wind speed, wind direction, wind pressure non-uniformity coefficient, topography and accelerometer on the wind-deflec- tion characteristics of the insulator are studied respectively. The results show that the horizontal span has a positive correlation with the insulator wind deflection angle, and the vertical span has a negative correlation with the insulator wind deflection angle. In the case of a certain wind speed, the main influence range of the wind direction is within a range of ± 60° perpendicular to the line.
