Investigation of Thermoplastic Composite Material Replacing Epoxy Insulator in Medium Voltage Switchgear

基于对开关设备所用材料环保、回收再利用的要求,分析了环氧树脂在使用中不环保及性能方面的缺陷,确定采用环保热塑性工程塑料作为新材料替代热固性环氧树脂。通过分析PA、PC、PPO等热塑性工程塑料的力学、电性能及加工特性,筛选出新材料的基体树脂,依据材料特性确定改性路径,通过实验分析所制备的不同改性材料样片,研究出材料配方、改性工艺。试验结果表明,新型环保热塑性复合绝缘材料质量轻、强度高、无毒无害阻燃且可回收再利用,满足中压开关设备对绝缘材料性能的要求。

Based on the requirements of environmental protection and recycling of the material used for switching equipment,this paper analyzed the non environmental protection and the performance defects during the use of epoxy resin and determined that the environmental thermoplastic engineering plastics were used to replace the thermosetting epoxy resin.After mechanical,electrical and machining properties of these engineering thermoplastics,such as PA,PC and PPO were analyzed,this paper selected the suitable matrix resin of material,confirmed the modified path according to the material properties,carried out experimental analysis of preparative different modified material samples,and got the material formulation and modification process of this project.The test results show that the novel environmental protection thermoplastic composite insulation material is light in quality,high in strength,non-poisonous,unharmful,anti-flaming with reclcying and reusing,which meets the requirements of insulating material property for the medium voltage switchgear.
