摘　　要：绝缘子闪络引起的线路短路跳闸事故高发,对闪络早期的异常放电进行有效检测,能够降低闪络跳闸事故发生率。为此,本文研制了绝缘放电日盲型高灵敏紫外检测装置,对装置原理和技术参数进行了描述,对其日光环境下的响应性能、有效检测距离及检测视场范围进行了综合测试,并基于装置的响应输出特性,提出了基于光脉冲计数的放电相位统计分析方法,并与高频电流相位统计图谱进行了分析对比。本文提出的绝缘放电日盲型高灵敏紫外检测技术为基于无人机的线路外绝缘放电巡检提供了一种新手段。Flashovers on insulators frequently cause line short-circuit trips,which can be mitigated by effectively detecting abnormal discharges in the early stages of flashovers.To this end,this paper develops an ultraviolet detection device for insulator discharge that is highly sensitive and blind to daylight.The principles and technical parameters of the device are described,and its response performance in daylight environments,effective detection distance,and detection field of view are comprehensively tested.Based on the response output characteristics of the device,a discharge phase statistical spectrum analysis method based on photon pulse counting is proposed.The ultraviolet detection technology for insulator discharge that is highly sensitive and blind to daylight,as presented in this paper,provides a new means for UAV-based external insulation discharge inspection of power lines.
