摘要
针对表面微孔阵列的构筑方法与微孔阵列参数对绝缘子真空沿面闪络性能的影响, 设计了 2种阵列结构, 利用激光旋转微加工的方法在圆柱形有机玻璃绝缘子侧面进行了 2种阵列的构筑, 同时控制激光作用参数分别获得直径为 300 μm与 200 μm的 2种表面微孔, 最终得到 4种微孔阵列结构。扫描电镜 (SEM)与三维轮廓仪分析表明, 通过激光旋转微加工的方法, 实现了直径分别为 300 μm与 200 μm, 深度为 50 μm左右的微孔点阵构筑。沿面闪络测试表明, 表面微孔构筑能够有效地提升沿面闪络电压 (实验中闪络电压提升 50%以上), 微孔直径越小提升效果越好; 在同种微孔直径下, 点阵结构对闪络电压无明显影响。
Abstract
To study the construction method of the surface micro-hole arrays and the effect of lattice parameters on the surface flashover characteristics of the insulators, a couple of lattices are designed and constructed by laser spinning carving on cylindrical Poly Methy-Methacrylate(PMMA) insulators. Then, micro holes with the diameters of 300 μm and 200 μm are acquired by changing the laser parameters. Finally, four kinds of micro-hole lattices are obtained by the combination of hole diameters and the lattice structures. The Scanning Electron Microscopy(SEM) test and 3-D profile analysis of the surface morphology indicated that the designed arrays are obtained on the lateral surface of the cylindrical PMMA insulators by laser treatment with the hole diameters of 300 μm, 200 μm and 50 μm in depth. Surface flashover voltage test shows that construction of micro-hole array on the surface of insulator could enhance the flashover strength of the insulators efficiently(over 50% flashover voltages increase is obtained in the experiment); the flashover voltage increases with the decrease of hole scales, but has no obvious relationship with the array structure.
