摘要
Abstract
Study on SF6 combination of electrical partial discharge detection and precise location is of great significance to improve equipment maintenance efficiency. In this paper, some special cases GIS partial discharge pinpoint problems, first, a new type of wideband UHF (0. 74 GHz) equiangular spiral antenna sensor is developed, and comprehensive treatment and delay times based on the weighted average of the positioning of the partial discharge wave form algorithm are proposed, and a method for auxiliary confirmation of partial discharge defects based on X-ray excitation is established. Taking the spot location of GIS partial discharge defect in the 220 kV station No. 2 transformer as an example, compared with the existing UHF location method, it has been proved that the integrated diagnosis method proposed in this paper is more effective for the precise location of partial discharge in some special cases.关键词
