电力线路改造作业模式思考

摘要

以电力行业线路改造工程为研究对象，详述了500kV线路改造测量的全过程，探讨了以RTK技术和TOPCON免棱镜全站仪相结合的野外作业方式提高数据采集的速度，对架设仪器时的“挑直线”原理进行了深入分析，并论述了相应的实际操作方法。%Based on the project of electric power line reconstruction, this article introduces the whole process of electric power survey in 500kV operation of Three Gorges in detail. Field working with RTK combined total-station instrument without prism greatly improves the speed in data collection. The article also deeply analyses the principle of find-line in erection of the instrument and gives its operation method.
