北斗系统在输电线路防灾监测中的应用探索

Exploration of Application of Beidou Navigation System to Disaster Prevention Monitoring for Transmission Line

输电线路覆盖范围广、输送距离长,沿途所经区域环境条件恶劣、地质地形复杂,存在巡检效率低、复巡周期长、监测数据不精确等问题。针对220 kV线路一基杆塔受地质扰动影响而出现塔基沉降杆塔发生主材形变、倾斜度增加,利用北斗系统及地基增强系统,采用综合分析法准确、可靠地获取毫米级监测数据,全面掌握各类风险的实时状态信息构建输电线路杆塔变形及塔基地质隐患防灾监测应用体系,为线路防灾应用提供技术参考。

Transmission lines cover a wide range,and have long transmission distances,bad environmental conditions and complex geological terrain,so there are many problems such as low efficiency of inspection,long cycle of re-inspection,inaccurate monitoring data and so on. In view of a 220 kV transmission line,there are tower foundation settlement caused by geological disturbance,the deformation of main materials and the increase of inclination of the tower. The Beidou navigation system and the foundation reinforcement system are used to accurately and reliably obtain high-precision monitoring data of millimetre level and comprehensively grasp the real-time status information of various risks. Through constructing the disaster prevention monitoring system for tower deformation and geological hazards of tower foundation in transmission lines,the field application and data analysis provide a technical reference for the application of line disaster prevention.
