摘　　要：针对无人机搭载特高频局部放电检测装置受变电站设备带电距离影响的问题,从小型传感器、扩充接口及数据处理三方面进行小型化改造,研制无人机搭载特高频局部放电检测小型化装置。结合实验室与现场测试结果,获取悬浮、尖端、沿面三种放电类型的PRPD-PRPS图谱,研究放电信号与距离的关系,验证了装置在变电站现场灵敏度好、可靠性强、操作便捷。该装置可为无人机特高频检测方式提供参考,为电力设备局部放电智能巡检提供新方法。Aiming at the problem that UHF partial discharge detection device carried by UAV is affected by the charged distance of substation equipment,it is necessary to miniaturize the device from the three aspects of small sensors,expansion interfaces and data processing.By combining laboratory and on-site test results,PRPD-PRPS spectra of three types of discharges are obtained,including suspended,tip and surface discharge.The relationship between discharge signals and distance is studied,and the device is verified to have good sensitivity,high reliability and convenient operation at the substation site.This device can provide a reference for the UHF detection method through UAV and a new method of intelligent inspection for partial discharge of power equipment.
