主　　题：Charge accumulation DC gas insulated equipment review spacer 

摘      要：Charge accumulation on the spacer surface in gas insulated equipment is very severe in the DC field,leading to easy flashover,which restricts the application of DC GIS/***,knowledge about the charge accumulation characteristics of gas insulated equipment at DC stress is *** this paper,we reviewed the research methods and the characteristics of charge accumulation on spacers.A summary of charge measurement methods and setups are *** the surface charge inversion algorithms are *** the simulation model for charge accumulation in the DC field is ***,the charge accumulation mechanisms and phenomenon,the influence factor of surface charge accumulation and the influence of accumulated charge on spacer insulation characteristics are *** addition,some suppression methods of surface charge accumulation are ***,based on the understanding of charge accumulation on spacers,some suggestions on further studies are presented to aid in the design of a better spacer free from surface charges.
