Construction of micro-structure on polymer insulators and their surface flashover characteristics

  • 摘要: 对聚合物绝缘子表面微形貌的构筑方法及其对沿面闪络性能的影响进行了研究。首先以二氧化硅微球为模板,利用化学模板法在交联聚苯乙烯(CLPS)表面实现了μm级孔穴的构筑,研究了二氧化硅微球的颗粒直径及添加量对微孔参数的影响;其次,利用激光刻蚀的方法在有机玻璃(PMMA)绝缘子表面实现了百μm级三角形凹槽阵列的构筑,探索了激光工艺参数对微槽形貌和结构的影响。通过短脉冲高压测试平台对构筑了两种不同微形貌的绝缘子进行了真空沿面闪络性能测试。结果表明:沿面闪络电压均获得了显著提升,其中表面带有合适微槽的PMMA绝缘子的闪络电压相比于未处理的绝缘子提升了将近150%;与传统的表面机械加工处理方法相比,在聚合物表面实现了从μm到数百μm量级微结构的可控构筑,并使真空沿面闪络电压获得了稳定提升。
