Development of Studies about Surface Charge Accumulation on Insulating Material under HVDC
摘要
Abstract
With the development of dc transmission technique,DC gas insulated switchgear (GIS) is attracting more and more attentions.DC GIS has the advantages of compact size,high reliability and little maintenance.Compared with ac GIS,the surface charges accumulating on the cone-type insulator is more serious for dc GIS,which can lead to the decrease of its surface flashover performance and hence restricts the application of dc GIS in engineering.At present,the investigation about the characteristics of surface charge accumulation and the corresponding suppression means under HVDC is a hot topic.In this paper,the related studies were reviewed,including the techniques of surface charge measurement and inversion algorithm,the accumulation ways and corresponding sources of surface charges,the influencial factors and suppression methods of surface charge accumulation.At last,some proposals for the future investigation of surface charge accumulation were presented.关键词
