紫外成像技术在电力设备局部放电探测中的应用

The Application of UV Imagery Technology in Electrical Equipment PD Detection

分析了紫外成像技术检测电力设备局部放电的基本原理和影响紫外探测设备探测结果准确度的几种因素,并阐述了紫外成像探测技术的国内外发展状况,结果表明,空气温度、湿度、仪器增益水平、风力,以及测试距离都会对测试结果产生影响.

The characteristics and operating principle of UV imaging device are introduced. Then the several factors that have impact on the detection accuracy of the UV-detection equipment are analyzed after describing the development status and trend both at home and abroad. The results show that air temperature, humidity, instrument gain level, the wind, the measurement distance will have an impact on the accurate measurement of partial discharge level and location.
