摘　　要：利用新型PVDF柔性压电薄膜设计出了一种用于检测和定位GIS闪络故障位置的装置,为验证基于新型PVDF压电薄膜传感器GIS故障快速定位装置的可靠性,设置了GIS交流耐压试验中四种典型的导致GIS发生闪络的缺陷模型,开展了不同放电缺陷模型下的GIS闪络故障定位装置实用性研究。研究表明:通过比较各气室声强大小,基于新型PVDF压电薄膜传感器GIS故障快速定位系统能快速有效定位GIS故障位置,避免重复打压对GIS绝缘造成累积性的破坏。In this paper,a device for detecting and locating the fault location of GIS flashover is designed by using new-style PVDF flexible piezoelectric thin film. In order to verify the reliability of GIS fault fast positioning system based on new-style PVDF piezoelectric film sensor,four different kinds of typical defects were set in this paper,and the practical research on GIS flashover positioning was carried out. The research result shows that by comparing sound intensity of different gas rooms,GIS fast fault location system based on new-style PVDF piezoelectric film sensor can quickly and efficiently located GIS fault location,and avoid cumulative damage to GIS insulation caused by duplication of pressure.
