架空输电线路新型防鸟装置的研制及应用

Development and application of a novel birddeterrent device for overhead transmission lines

鸟害故障在宁夏石嘴山地区110 kV及以上输电线路故障中所占比例逐年升高,已成为影响电网安全稳定运行的主要因素之一,亟需加强治理,因此,对红外线感应超声波脉冲驱鸟器和磁吸式防鸟挡板两种防鸟装置进行研制,对他们的结构、工作机制、安装应用方式进行设计。研制出的成品装置在鸟害高发的某110 kV输电线路进行试验应用。试验结果表明,红外感应超声波脉冲驱鸟器能准确感知鸟类大小、飞行速度等关键信息,并在适当位置发射脉冲波。磁吸式防鸟挡板安装简便,防护范围满足要求。两者组合应用可有效防范鸟害故障。

In Shizuishan region of Ningxia,bird-induced faults in overhead transmission lines of 110 kV and above have seen a steady rise,emerging as a significant factor affecting the safe and stable operation of the power grid.There is an urgent need for remedial measures.So an infrared sensor-driven ultrasonic pulse bird repellent and a magnetically affixed bird deterrent baffle are developed.Their structures,working mechanisms,installation and application modes are designed.The developed devices are trialed on a 110 kV transmission line prone to bird disturbances.Results show that the infrared-induced ultrasonic pulse repellent accurately detects bird size and flight speed,triggering pulse emissions at optimal locations.The magnetically affixed bird deterrent baffle offers convenient installation with a satisfactory protection range.Their combined application proves effective in countering bird-induced disruptions.
