【摘要】：本文阐述了复合材料杆塔应用于输电线路工程的重要意义,综述了目前国内外在该方向的研究现状。在充分了解各种复合材料性能的基础上,结合输电线路工程特点,对复合材料类型和成型工艺进行了选择。在充分总结750kV等线路复合材料杆塔应用研究已经取得的成果基础上,尤其是以往使用“免横担组合绝缘子杆塔”工程经验的基础上,结合目前在建工程的特点,推荐在局部平丘地段采用复合材料横担杆塔,起到降低塔重、降低基础混凝土量、减小走廊宽度,从而降低综合造价的作用。本文针对平丘地区轻冰区直线塔,对复合材料横担杆塔进行了电气部分和结构部分的方案优化设计,对其中重要参数进行了明确,并与常规钢管塔进行了材料经济性比较,提出了复合材料横担直线塔的应用建议。
[Abstract]:In this paper, the significance of composite tower application in transmission line engineering is expounded, and the current research situation in this direction at home and abroad is summarized. On the basis of fully understanding the properties of various composite materials, combined with the characteristics of transmission line engineering, The type and forming process of composite materials are selected. On the basis of summing up the achievements in the application and research of composite tower of 750kV and so on, especially on the basis of the past engineering experience of using "composite insulator tower without cross pole", According to the characteristics of the current construction project, it is recommended that the composite crossbar tower should be adopted in the local flat hill area, which can reduce the tower weight, reduce the amount of foundation concrete, and reduce the width of the corridor. So as to reduce the effect of comprehensive cost. In this paper, aiming at the straight line tower of light ice area in Pingqiu area, the scheme optimization design of the electric and structural parts of the composite pole tower is carried out, and the important parameters are defined. Compared with the conventional steel tube tower, the material economy is compared, and the application suggestion of the composite steel pipe straight line tower is put forward.
