摘要
Abstract
The adhesive-impregnated paper dry bushing has the advantages of oil-free,explosion-proof,and stable electrical characteristics.As an important component of high-voltage electrical equip-ment,it has been widely used in transformers,reactors,valve hall through walls and other scenarios.The capacitor core is the main insulating part of the bushing,and the microscopic damage of the core composite material may eventually lead to mechanical and electrical failures of the equipment.The re-search on the damage properties of dry bushing core composite material is of great significance.In order to accurately reflect the actual performance of composites in dry bushing core,samples were directly cut from the dry bushing core.The mechanical damage properties of dry bushing core composites have been tested and studied to obtain the relationship between microscopic damage and macroscopic failure values.The mechanical damage of the composite was studied by means of universal electronic tensile machine,a-coustic emission technology,and 3D X-ray computed tomography technology,etc.The mechanical property data of the core composite material has been obtained,and the damage mechanism and process have been analyzed,which provides basic material parameters and design principle for the similar dry bushing.关键词
