新能源汽车驱动电机用槽绝缘材料油品兼容性及试验研究
Oil compatibility and characteristics of insulating paper materials for new energy vehicle drive motors
摘要
Abstract
According to the T/CEEIA 415 standard,taking the drive motor slot insulating material as the research object,three kinds of interstitial aramid insulating papers with 0.25 mm thickness are selected for the oil compatibility test,and based on the changes of the physical,chemical,electrical,and mechanical properties of the insulating paper surfaces in different cycles,the degree of damage and the degradation factors of the materials are elaborated in detail.The results indicate that in the oil compatibility test,the porous structure and surface capillarity enhance the densification of the paper-based structure in the short term,which is beneficial to the electrical performance.However,with the increase of the test time,the diffusion of moisture in the automatic transmission fluid in the oil-paper insulating system is intensified,which triggers the formation of insulating defects and results in the attenuation of the mechanical strength.When screening insulation materials,changes in mechanical properties are more intuitive and accurate.In addition,due to the destruction of the hydrogen bond stabilizing configuration,the amide bond and the C=O bond strength are changed,and the dielectric properties of the lower density paper deteriorate significantly.关键词
