基于介观接触形貌分析的XLPE-SiR界面击穿特性
Breakdown Characteristics Analysis of XLPE-SiR Interface Based on Mesoscale Contact Morphology
摘要
Abstract
Contact morphology of the solid-solid composite insulation interface is the key to determine the insulation level of cable accessories.In this paper,a mesoscopic contact-characteristic analysis model of the XLPE-SiR interface is established based on the hyperelasticity constitutive relationship and the equivalent roughness method,and the accuracy of the analytical model is verified by internal contact interface observation of an actual XLPE-SiR interface sample.Then based on this model,the influence of surface roughness and contact pressure on the internal contact characteristics,such as the actual contact area ratio and cavity size,is studied.Finally,with the interface breakdown experiment,the influence of the interface contact morphology on the interface breakdown strength is explored.It is found that the actual contact area ratio of the solid-solid composite interface decreases exponentially as the material surface roughness increases,but increases linearly as the interface pressure increases.With the increase of the actual contact ratio of the interface,the interface breakdown voltage increases exponentially,while the breakdown voltage dispersion increases first and then decreases.关键词
