Abstract：Inorder to further improve theinsulationperformanceof theswitch fuse material，amodifiedcomposite insulation material was prepared by introducing nano-aluminaand nano-boron nitride，and its insulation performance，mechanical properties and application effect were verified.The results show that the modified composite insulation material prepared byintroducing nano-alumina and nano-boron nitride has stronger insulation performance. The volume resistivity，partial discharge onset voltage and breakdown field strength are increased by 32. 12% ， 12.12% and 7.05% ，respectively ，compared with the unmodified composite insulation material. The composite insulationmaterial has better tensile debonding strength and tensile shear strength.When thecomposite insulation material isusedasthe fusing material of the drop switch，it shows better insulation performance.The modifiedcomposite insulation material prepared by has good insulation and mechanical properties，andcan be used as afusing material for drop switches.
Keywords：switch fuse material；nanoparticles；material modification；insulation performance；coupling treatmen
當(dāng)前，引入納米粒子對(duì)材料進(jìn)行改性是增強(qiáng)復(fù)合材料絕緣性的常用方式之一，隨著當(dāng)前生產(chǎn)生活中用電需求的不斷增加以及用電場(chǎng)景十分復(fù)雜，對(duì)熔斷式開(kāi)關(guān)的性能提出了更高要求。（剩余5898字）
