| 摘 要： | 通过搭建脉冲加载下的激光辐照沿面闪络实验平台,考察了锥角绝缘子受激光辐照时的真空沿面闪络性能。结果表明:不论是紫外光(266nm)还是可见光(532nm)辐照在阴极三相点或者样品中间,+45°锥角绝缘子构型的性能都要优于-45°锥角绝缘子,并且紫外辐照阴极三相点对沿面闪络电压的影响较大,因此在大型脉冲功率装置中应该避免射线对绝缘堆阴极三相点处的辐照。

| Abstract: | An experiment platform of laser illumination together with pulsed voltage excitation was built. The vacuum surface flashover performance of an angled-insulator was studied. The results show that the performance of +45 insulator is better than that of －45 insulator when UV laser (266 nm) or visible laser (532 nm) illuminates at either the cathode triple point or the sample center. The effect of the UV laser illumination on the cathode triple point is prominent, and it is important to shield this area against UV light in the design of vacuum insulators. |
