【Abstract】 The graphene copper based composite material contacts have a great potential to be applied broadly in power switchgears due to its such advantages as excellent ablation resistance,high electrical conductivity and high thermal conductivity. However,there are few reports on the electrical performance such as insulation withstand voltage,interruption capability and current carrying charcateristic of the graphene copper based composite contact material in vacuum environment. In this paper the research progress in the preparation techniques,physicochemical properties,and electrical conductivity of graphene-copper composite contacts are reviewed.The experimental methods and findings regarding the arc ablation resistance,voltage withstand capability,and current-limiting characteristics of other copper-based contact materials are also summarized. Additionally,the current shortcomings in the application research of graphene-copper composite material in vacuum switch are proposed. The study result in this paper can provide a theoretical basis and technical reference for the application of graphene copper based composite material contacts in vacuum switchgear.更多还原
