摘要

本文研究了由铸造环氧树脂与纳米介电颗粒混合而成的纳米介电材料在部分真空条件下的表面闪络特性。样品呈圆柱形,研究中使用了不同的电极配置和间距。将圆柱形样品夹在两个平行的极板电极之间,记录并分析闪络过程中的电压、电流和光发射波形。直流和20khz脉冲单极信号分别使用。对于横向配置,电极放置在样品的平面上。并与平行板的情况作了比较。

Surface flashover of nanodielectrics with varying electrode architectures in partial vacuum under DC and kHz pulsed fields
In this work, the surface flashover characteristics of nanodielectric materials composed of cast epoxy resin mixed with nano-dielectric particles in partial vacuum are studied. The samples are in cylindrical shape and varying electrode configurations and spacing are used in the study. The cylindrical samples are sandwiched between two parallel plate electrodes, and the voltage, current, and light emission waveforms during the flashover events are recorded and analyzed. Both dc and 20 kHz pulsed-unipolar signals are used separately. For lateral configuration, electrodes placed on the samples' flat surface. Comparisons to the parallel plate case are made.
