甘油具有高储能密度和高电阻率，是一种很有前途的脉冲功率系统液体介质。为了进一步提高甘油的储能密度，需要对其击穿特性进行研究。实验研究了甘油在重复脉冲形成线（PFL）中单脉冲和重复脉冲两种工作模式下的击穿电压下降规律。实验结果表明，在10 s内经过100次脉冲后，甘油PFL的击穿电压降低了约35%。甘油中的气泡被怀疑是影响击穿特性的重要因素。利用高速摄像机观察到了气泡的变形（尤其是高度），并且在多次脉冲后气泡的变形是累积的。实验证实了电场、压力、温度等因素对气泡高度的影响。这些实验结果揭示了重复脉冲模式下液体击穿的重要过程，有助于改善液体介质的击穿特性。甘油具有高储能密度和高电阻率，是一种很有前途的脉冲功率系统液体介质。为了进一步提高甘油的储能密度，需要对其击穿特性进行研究。实验研究了甘油在重复脉冲形成线（PFL）中单脉冲和重复脉冲两种工作模式下的击穿电压下降规律。实验结果表明，在10 s内经过100次脉冲后，甘油PFL的击穿电压降低了约35%。甘油中的气泡被怀疑是影响击穿特性的重要因素。利用高速摄像机观察到了气泡的变形（尤其是高度），并且在多次脉冲后气泡的变形是累积的。实验证实，气泡的高度受电场、压力和温度等因素的影响。这些实验结果表明，…
Glycerin is a promising liquid dielectric for pulsed power systems because of its high storage energy density and high resistivity. In order to further improve the energy storage density of glycerin, its breakdown characteristics should be investigated. In this paper, experiments are carried out to study the decline of the breakdown voltage of glycerin in a repetitive pulsed pulse forming line (PFL) in both the single pulse mode and the repetitive pulsed mode. It is shown that the breakdown voltage of the glycerin PFL is reduced by about 35% after 100 pulses in 10 s. The bubbles in glycerin are suspected to be an important factor affecting the breakdown characteristics. By using a high-speed camera, the deformation of bubbles (especially the height) is observed in the experiments and the deformation of bubbles is cumulative after multiple pulses. Experiments confirm that the bubbles’ height is influenced by factors including the electric field, pressure, and temperature. These experimental results demonstrate an important process of the liquid breakdown in the repetitive pulsed mode, which will be helpful to improve the breakdown characteristics of liquid dielectrics.Glycerin is a promising liquid dielectric for pulsed power systems because of its high storage energy density and high resistivity.
