摘要
重冰区杆塔因其履冰荷载较大,成为杆塔设计时的主要控制条件。本文以220kV恩利线工程重冰区杆塔为分析对象,介绍了重冰区线路的杆塔规划,详细分析了重冰区杆塔的选型,论述并总结了杆塔结构设计与优化的原则和措施。
When the towers are designed in the heavy icing area,the major controlled condition is the ice loading because of its larger value.This paper takes the towers of the 220 kV Enshi-Lichuan transmission line project in the heavy icing area as an analyzed object.The towers plan in the heavy icing area is introduced,the selection of transmission tower for heavy icing area is analyzed in detail,and the principles and measures for the tower structural design and optimization are discusses and summarizes.
