摘要
直流换流站电磁环境比交流变电站更复杂,无人机在站内高压设备间狭小区域飞行的安全性还有待研究。而随着高倍变焦云台相机的开发,远距离图像采集能力大大提升,给换流站无人机巡检提供了新思路。分析了直流换流站的电磁环境特点,探讨了搭载高倍变焦云台相机的无人机远距离巡视的可行性,研究了巡检方法,并以一起换流站中的设备发热缺陷巡查为例,介绍了实际使用效果。
The electromagnetic environment of DC converter station is more complex than that of AC substation,so the safety of UAV flying in the narrow area between high-voltage equipment in the station needs to be studied.With the development of high-zoom pan/tilt cameras,the ability to collect long-distance images has been greatly improved,providing new ideas for drone inspections at converter stations.The characteristics of the electromagnetic environment of the DC converter station are analyzed,the feasibility of long-distance patrols by UAVs equipped with high-zoom pan/tilt cameras is discussed,and the inspection methods is studied.Taking a heat defect inspection of equipment in a converter station as an example,the actual use effect is introduced.
