FRP在杆塔改造中的应用
|
摘要
近年来因110 kV汶满Ⅰ、Ⅱ线通道环境变化,为防止线路遭受外力破坏,需要对其进行改造。针对杆塔对地距离不足且无法加高的问题,应用FRP复合绝缘材料对20号、21号塔进行改造,将角钢塔塔头更换为复合绝缘材料,导、地线直接挂在绝缘横担上,去掉悬垂绝缘子长度,提升导线对地安全距离,改造后的杆塔能有效提高线路安全运行水平。
The No.20 and No.21 towers of Wenman transmission line are in need of renovation because of the change of the channel environment in recent years.For problems that the distance of towers to the ground is small and the height of towers can not be increased, FRP is used in the renovation.The angle steel tower head is replaced with FRP, the guide line and the ground line are directly link to the insulation cross arm, and the suspension insulator is removed, so the distance of the wire to ground is improved to a safe distance.The improved towers can effectively improve the safe operation of the line.
