Electrical breakdown voltage ( V BD ) and streamer propagation path characteristics in highly non-uniform electrode system were investigated to clarify the dielectric barrier effects. The experimental results showed that V BD is affected by both the barrier dimension and the barrier position. As the position of the dielectric barrier becomes closer to the needle electrode, the rising rate of V BD according to the barrier dimension increases. In addition, streamer propagation path could be identified into two categories, depending on the dielectric barrier position and the dimension. Finally, it is found that V BD s were determined by the electrical insulation structure, not the streamer propagation path or length.

雷电冲击电压下带电木屏障的非均匀电极系统的电击穿特性

研究了高度非均匀电极系统中的电击穿电压 (V BD ) 和流光传播路径特性，以阐明介电势垒效应。实验结果表明，V BD 受势垒尺寸和势垒位置的影响。随着介电势垒的位置变得更接近针电极，V BD 根据势垒尺寸的上升率增加。此外，根据介质阻挡层的位置和尺寸，拖缆传播路径可以分为两类。最后，发现V BD s 是由电绝缘结构决定的，而不是由拖缆传播路径或长度决定的。
