摘　　要：氧化锌避雷器在线监测装置是预防避雷器绝缘故障最有效的方法之一,而变电站规模大,传统的避雷器在线监测装置需要大量布线,工作量巨大。开发一种基于LoRa通信的无源无线避雷器监测装置,该装置无需供电布线,安装便捷。通过河北1000 kV邢台变应用在线结果与离线仪器检测结果比对,验证了该装置的精确度、稳定性与有线装置无异,具备很好的应用推广价值。The on-line monitoring device of zinc oxide arrester is one of the most effective methods to prevent the insulation failure of arrester.The scale of the substation is large,and the traditional lightning arrester online monitoring device requires a lot of wiring,and the workload is huge.A passive wireless arrester monitoring device based on LoRa communication has been developed,which does not require power supply wiring and is easy to install.By comparing the online results of Hebei 1000 kV Xingtai application with the offline instrument test results,it is verified that the accuracy and stability of the device are no different from those of the wired device,and have good application and promotion value.
