摘　　要：制备了碳化硅/有机化蒙脱土/环氧树脂微纳米复合非线性防电晕材料,实验分析了复合材料中碳化硅和有机化蒙脱土的含量对材料介电性能的影响,并对应用该复合防电晕材料的线棒进行试验,测试了线棒的耐电晕性能以及防晕区表面温度。结果表明:一定含量的纳米有机化蒙脱土的加入能有效提高SiC防电晕复合材料的非线性特性,降低线棒防晕区域表面温度,提高耐电晕性能。A silicon carbide/organic montmorillonite/epoxy resin micro-nano non-linear corona resistant composite material was prepared.The influence of silicon carbide and organic montmorillonite content on the dielectric properties of the corona resistant material was studied.Bars were prepared using the corona resistant material,and their corona resistance and surface temperature were tested.The results show that the addition of a certain amount of nano organic montmorillonite could effectively improve the non-linear characteristic of the corona resistant composite,reduce the surface temperature of anti-corona area,and improve the corona resistance of bars.
