多旋翼无人机检测输电线路绝缘子研究

Detection Transmission Line Insulators Using Multi-rotor UAV

绝缘子作为支持导线的绝缘体,可以保证横担、杆塔与母线等带电体有足够的绝缘性,其性能好坏对电网的安全运行起着至关重要的作用。在长期运行中,绝缘子性能会受到环境因素、电流作用、机械力作用的影响和破坏,因此需要在电力线路正常运行情况下对高空中的绝缘子性能进行检查。研究一种利用多旋翼无人机对绝缘子检测装置,主要利用多旋翼无人机这种安全稳定的高效手段,通过测量绝缘子两端电势与正常值相比较的方法实现对绝缘子状态的检测。利用该装置和方法,能够及时了解和掌握线路绝缘子的运行情况,判断是否存在安全隐患,为有效决策提供依据;还能够避免检测人员爬高进行近距离带电操作的危险性,同时提高检测效率。对输电线路安全性及无人机巡检可利用范围的延伸具有很大的实际意义。

As the conductor insulator,insulators ensure enough insulation of the cross arm,tower,and bus,and play a vital role in the safe operation of the grid.In the long-term work,insulators performance is affected and damaged by environmental factors,current and mechanical forces.It is necessary that the insulators performance can be checked in the case of the normal operation of the power line.The equipment and method for detection transmission line insulators are described using multi-rotor UAV.This device detects insulators with a safe and stable multi-rotor UAV,using the method of comparing the measured value and the correct value of the potential of both ends of the insulators.Using this equipment and method,not only as a means of monitoring,can master the operation of the line insulator and the existence of security risks timely,to provide the basis for effective decision-making.It still be able to avoid the risk of inspection personnel for live operation,while improving detection efficiency.The detection method has great practical significance for the security of the transmission line and range extending of using multi-rotor UAV.
