X射线激励下局部放电的研究进展
Review on X-Ray Induced Partial Discharge
摘要
Abstract
X-ray has the capability to ionize the dielectrics due to its relative high energy,and it may have a potential influence on partial discharge (PD) process.In this paper,the PD phenomena induced by X-ray are explained,such as void discharge in solid insulation,void discharge and oil gap discharge in oil-paper insulation.Then,the mechanism of the X-ray induced PD is reviewed,including X-ray would supply enough electrons for voids,decrease the statistical lag of voids and reduce the partial discharge inception voltage (PDIV).After that,the application of X-ray induced PD techniques in the GIS main insulation,the epoxy resin casting insulation and the oil-paper insulation are summarized.Last but not the least,the future research emphasis on X-ray induced PD techniques in insulation assessment is revealed.关键词
