Research on Anti-interference Aechnology of Water Flushing UAV in High Voltage Electromagnetic Field

近年来无人机等先进技术在电力系统的广泛应用,对提升高压输电线路的运维效率起到了积极作用。结合输电线路的运维中出现较多的污闪事故,研发具有国内先进水平的无人机带电水冲洗系统,将大大提高线路绝缘子的水冲洗效率、质量,同时保证作业人员的安全。由于水冲洗系统需要靠近铁塔和导线作业,高压电磁场对无人机飞控系统及测控部件造成干扰,结合我国南方地区电网典型的线路塔型,开展电磁干扰的分析研究,一方面采取技术措施确保系统安全飞行,另一方面,进一步优化作业路径,有效确保了无人机水冲洗系统带电作业的安全、可靠。

In recent years,the extensive application of UAV and other advanced technologies in the power system has played a positive role in improving the operation and maintenance efficiency of high-voltage transmission lines.Combined with the occurrence of many pollution flashover accidents in the operation and maintenance of transmission lines,this paper developed a domestic ad-vanced UAV water flushing system,which will greatly improve the water flushing efficiency and quality of line insulators and ensure the safety of operators.Because the water flushing system needs to be near the line Tower and conductor,high voltage electromagnetic field to the UAV flight control system and measurement and control components causing interference,this paper typical line tower in the south China power grid,to carry out the analysis and study of electromagnetic interference,on the one hand,technical measures are taken to ensure flight safety system,on the other hand,further optimize operation path,It effectively ensures the safety and reliability of live operation of uav water flushing system.
