摘要
受酸雨、盐雾及覆冰灾害的影响,输电线路中复合绝缘子憎水性逐渐降低,需定期对绝缘子憎水性进行检测。在传统的人工检测方法中,由于其作业时间长、劳动强度大且风险系数高等问题使得难以按期对绝缘子进行检测。因此,该文提出一种基于多旋翼无人机的复合绝缘子憎水性检测方法及其装置研究。装置包含六旋翼无人机、自动喷水系统、无线遥控系统、视频采集传输系统和憎水性检测系统。地面操作人员通过操控无人机带电作业,控制直流微型电子隔膜泵生成可调节散开型水流,均匀喷洒于目标复合绝缘子,此过程中相机的可视模式功能可辅助喷洒作业。同时,控制相机云台对目标复合绝缘子拍照,将目标绝缘子图像传输到地面并通过憎水性图像分析软件对目标绝缘子的憎水性进行分析。试验结果表明,在整个检测过程中,该方法及装置具有自动化、无人化以及远程化的优点,在绝缘子带电检测中能给予作业人员安全保障,并能准确判别绝缘子的憎水性。
Due to the influence of the acid rain,salt spray and ice hazard,the hydrophobicity of composite insulators would be reduced gradually.It is necessary to detect the hydrophobicity of insulators regularly.The periodic detections of insulators are difficult due to the problems as the long operation time,high labor intensity and high risk coefficients.Therefore,a hydrophobicity detection method of composite insulators based on the multi-rotor UAV(unmanned aerial vehicle)is proposed and the corresponding device is also developed in this paper.The device is composed by a six-rotor UAV,an automatic water spray system,a wireless remote control system,a video capture transmission system and a hydrophobicity detection system.The live working is carried out by controlling the DC microelectronic diaphragm pump to generate adjustable diffused water to spray on the target composite insulator evenly.During this process,the visual mode function of camera can be employed to assist the spraying operation.Then,photos of the target composite insulator are taken by the camera and then transmitted for hydrophobicity analysis.Finally,a test is included for verification.It is shown that the method and device have the advantages of automation,unmanned and remoteness in the whole detection process.The safety of operators can be guaranteed,and the hydrophobicity of composite insulators can be detected accurately.
