低风压绝缘导线配电线路应用研究

大风工况下,架空导线所受的风压约占整个线路所受风压的50%~70%。通过降低导线所受的风压能极大地提高线路抗风能力。该文通过分析介绍配电网架空线路大风情况下杆线所受风压情况,研究优化架空绝缘导线结构,得出体型系数(风阻系数)低且便于生产制造的低风压绝缘导线,提高配电网线路抗风压能力。

Under strong wind conditions,the wind pressure on the overhead wire accounts for about 50%to 70%of the wind pressure on the entire line.By reducing the wind pressure on the wire,the wind resistance of the line can be greatly improved.Based on the analysis and introduction of the wind pressure on the rod and wire of the distribution network under the condition of strong wind,this paper studies and optimizes the structure of the overhead insulated wire,and obtains the low wind pressure insulated wire with low shape coefficient(wind resistance coefficient)and convenient for production and manufacturing,so as to improve the wind pressure resistance of distribution lines.
