Abstract

为了更准确地监测电力系统的运行状况,提出了一种应用于电力变压器局部放电(partial discharge,PD)检测的分立式多点检测方案。该方案基于光纤外差式干涉原理,传感系统由4个传感头构成,以实现多点检测和局部放电声源的定位。通过优化设计传感头的结构提高了传感器的灵敏度,同时传感器紧凑型的封装方式使其能够安装在电力变压器内部,提高检测结果的准确度。实验结果表明,该传感方案的单通道分辨率可达4 mrad,同时对构造的三相电力变压器模型进行了实验演示和分析,在对150 kHz局部放电超声多通道测量时,可实现声源定位的分辨率为 1 cm。由于该方案结构小巧、分辨率高及成本低廉,其在电力系统安全检测中有着巨大的应用潜力。

光纤离散多点局部放电检测与定位技术
为了更准确地监测电力系统的运行状况,提出了一种应用于电力变压器局部放电(partial discharge,PD)检测的分立式多点检测方案。该方案基于光纤外差式干涉原理,传感系统由4个传感头构成,以实现多点检测和局部放电声源的定位。通过优化设计传感头的结构提高了传感器的灵敏度,同时传感器紧凑型的封装方式使其能够安装在电力变压器内部,提高检测结果的准确度。实验结果表明,该传感方案的单通道分辨率可达4 mrad,同时对构造的三相电力变压器模型进行了实验演示和分析,在对150 kHz局部放电超声多通道测量时,可实现声源定位的分辨率为 1 cm。由于该方案结构小巧、分辨率高及成本低廉,其在电力系统安全检测中有着巨大的应用潜力。

期刊介绍: Journal of Applied Optics was founded in 1980, and its domestic and international publication numbers are ISSN 1002-2082 and CN-61-1171/O4. The journal is a technical journal sponsored by the China Ordnance Society and the 205th Institute of China Ordnance Industry. It was included in the "China Science and Technology Core Journal" in April 2006 and in the "Chinese Core Journal" in December 2008. It is included in the journals of important international retrieval institutions such as the American Chemical Abstracts (CA), Cambridge Scientific Abstracts (CSA), Russian Abstracts Journal (AJ), British Scientific Abstracts (INSPEC), Ulrich's Periodical Directory (UIPD), and Polish Index Copernicus (IC). The purpose of the journal is to track the research trends of high-tech at home and abroad, and comprehensively reflect the development status, research level, and application of optoelectronic technology at home and abroad; focus on optoelectronic application technology, advocate scientific research, be close to readers, and be close to enterprises, and focus on reporting new theories, new technologies and new methods, new products, and development trends in the field of optoelectronic technology at home and abroad. This journal solicits research papers on engineering optics, optical information acquisition and processing, optical metrology and detection, low-light-level night vision technology, fiber optic sensing technology, infrared application technology, laser application technology, optoelectronic devices, thin film optics, optical processes and equipment, and displays.
