一种基于GIS的三维跳线弧垂确定方法
摘要：
本发明涉及一种基于GIS的三维跳线弧垂确定方法，所述方法包括(1)计算跳线最小容许弧垂；(2)校验最小容许弧垂fpm；(3)迭代计算最小容许弧垂fpm；(4)计算跳线最大容许弧垂fPM；(5)选择跳线施工弧垂fp0；(6)计算四分裂跳线的摆动弧垂；(7)计算跳线弧垂长度。本发明可以提高在杆塔上的作业效率和安全性，从而缩短工期，节约人力及提高安装质量。在工程中降低了工程造价，提高了安全性和效率，满足了线路工程使用要求，提升了设计质量。并且采用本发明，可以在工程开展前对工程所需导线有一个量的了解，以减少在施工过程中对于导线的浪费，降低了施工成本，节约施工材料，从而增加了项目部施工效益。
摘要（英）：

The invention relates to a GIS (geographic information system)-based three-dimensional jumper sag determination method. The method includes (1) calculating the minimum tolerance sag f of the jumper; (2) examining the minimum tolerance sag f; (3) calculating the minimum tolerance sag f in an interactive manner; (4) calculating the maximum tolerance sag f of the jumper; (5) selecting a jumper construction sag f; (6) calculating a swing sag of a quad-bundle jumper; (7) calculating the sag length of the jumper. By the use of the method, operation efficiency and safety on a tower are improved so as to shorten the construction period, save labor and enhance mounting quality; construction cost is lowered during the construction, safety and efficiency are improved, use requirement of line project is met, and design quality is increased; wire number is available before construction, thus wire waste is avoided during the construction, construction cost is reduced, construction materials are saved, and construction benefits of the project department are increased.
