摘要： 结合实际工程,介绍了110kV架空输电线路设计中,采用单回路耐张角钢塔进行输电线路T接的应用效果:在普通单回路“干”字型耐张角钢塔下侧导线横担的下方,垂直方向处再增加一组导线横担,成“十”字排列;通过增加一组导线横担,实现了在单回路耐张角钢塔上对架空输电线路中的T接问题,输电线路T接过程中,导线始终保持三角排列,角钢塔结构受力更加合理。通过合理选择线路T接方式,使设计方案更加合理,在大幅节约角钢塔占地的同时,相应工程经济技术指标更优,并使输电线路停电时间更短,施工作业更加方便。

Abstract: Combining with practical engineering, this article introduces the application effect of using single circuit tension angle steel towers for T connection of transmission lines in the design of 110kV overhead transmission lines. Another set of wire cross arms were added vertically below the lower side of the wire cross arm of the ordinary single circuit “干” shaped tension angle steel tower, and a “cross” arrangement was formed. By adding a set of wire cross arms, the T-connection problem in overhead transmission lines was achieved on a single circuit tension angle steel tower. During the T-connection process of transmission lines, the wires are always arranged in a triangular pattern, and the force acting on the angle steel tower structure is more reasonable. By selecting the T connection method of the transmission line reasonably, the design scheme is made more reasonable. While significantly saving the land occupied by the angle steel tower, the corresponding engineering economic and technical indicators are better, and the power outage time of the transmission line is shorter, making construction operations more convenient.
