摘要
文章综述了基于超高频(UHF)的气体绝缘组合开关设备(GIS)绝缘在线监测近年来所取得的进展,包括在UHF传感器、GIS中UHF电磁波的传播特性、局部放电源识别和定位等方面取得的研究成果,并指出了UHF在线监测系统及其应用中存在的问题,如检测频带的选择等。最后还对未来UHF局放监测的研究方向进行了展望,指出新型传感器及快捷方便的定位方法等依然是研究的重点。
The progress of ultrahigh frequency (UHF) based on-line monitoring of gas insulated switchgear (GIS) in recent years is summarized, including the research results in the UHF transducers, the propagation characteristics of UHF electromagnetic wave in GIS, the recognition and location of partial discharge source and so on. The problems existing in the UHF based on-line monitoring system and its application, such as the selection of detecting frequency band, etc. The direction in the future research on UHF based partial discharge monitoring is looked ahead and it is pointed out that the easy and fast partial discharge location by new types of transducers is still the focal point of the research.
