摘要
Abstract
According to a live detection of 1 100 kV GIS, this paper describes the principles and technical advantages of UHF-based GIS partial discharge detection method;in addition, it analyzes the spectrogram in-formation of portable PD analyzer to preliminarily judge the defect type. At last, the discharge source is pre cisely located by means of time difference location method. The result of pattern recognition techniques of 1 100 kV GIS partial discharge on-line monitoring system is consistent with the field test, which verifies the ac-curacy of the on-site live detection. Practice shows that UHF partial discharge detection technique can recog-nize partial discharge due to GIS defects, and timely discover and prevent GIS insulation faults to ensure the operation security and stability of GIS.关键词
