线路直线塔地线及光缆金具维护

Research on Special Maintenance Tool of Straight Line Tower Ground and OPGW Cable in Overhead Transmission Line

本文在对架空输电线路直线塔地线支架和地线、OPGW光缆金具组装方式及杆塔荷载的分析计算基础上,结合机械设计基础理论,确定了初步的专用工具研制方案。通过自行购买材料、零部件,在加工、装配和试用过程中不断完善后,成功研制出一套地线、OPGW光缆金具维护的专用工具。该专用工具通过在不同电压等级线路、荷载情况下的4次现场试用,完全满足对35 kV^500 kV线路通用通用直线塔地线、OPGW光缆金具的维护工作,而且与传统的作业方法相比明显提高了作业安全性和工作效率。

Based on the basis of the calculation,combining with the basic mechanical design theory, and analysis of straight wire bracket and a ground wire,OPGW cable for overhead power transmission line and tower load, the special maintenance tool is pre-liminary designed. Through the purchase of materials, parts, continuous improvement in processing, assembly and trial process,successfully developed a set of wire,OPGW cable maintenance special tool. The special tool is through the field test for 4 times in different voltage grade line,load conditions,to meet the needs of 35 kV-500 kV line general linear tower wire,OPGW cable main-tenance work,and compared with the traditional operating method significantly improves the operation safety and efficiency.
