本研究的目的是确定不同的障碍物的位置上的液氮（LN 2）的直流击穿特性的效果，有和没有气泡。直流击穿电压测量针-板电极，9 mm间隙距离，有和没有40 μm厚的PTFE屏障绝缘。气泡的存在降低了击穿电压，并研究了在距针电极尖端不同距离处具有屏障的效果。结果表明，有气泡和无气泡时，势垒越靠近针电极，击穿电压越高。使用高速摄像机的观察表明，绝缘屏障的存在触发的LN 2 /绝缘屏障复合系统的击穿。
The objective of this study is to determine the effect of different barrier positions on the DC breakdown characteristics of liquid nitrogen (LN 2 ), with and without bubbles. The DC breakdown voltage is measured of a needle-to-plane electrode, with 9 mm gap distance, with and without PTFE barrier insulation of 40 μm thickness. The presence of bubbles lowers the breakdown voltage and the effect of have the barrier at various distances from the tip of the needle electrode is studied. The results show that with and without bubbles, the closer the barrier to the needle electrode, the higher the breakdown voltage. Observations using a high-speed camera show that the presence of the insulation barrier triggers the breakdown of the LN 2 /insulation barrier composite system.
