本文描述了在物理空间，如聚乙烯中的微空隙或自由体积中吸收的氧对电树的影响。用未经处理的样品和真空泵脱气的样品在室温下研究了AC树枝的形成和生长。脱气样品的树枝起始电压远高于未处理样品。实验结果表明，这种改善可以归因于PE中氧气的去除。我们还详细地观察了脱气样品中树枝的萌生和生长过程。结合其他结果，我们得出结论，从点电极注入的载流子在树的起始过程中起着主导作用。
This paper describes the effect on electrical treeing of oxygen absorbed in physical spaces such as microvoids or free volume in polyethylene. The ac tree initiation and growth were investigated at room temperature using untreated samples and also samples degassed by a vacuum pump. The tree starting voltage of the degassed samples is much higher than that of untreated samples. The experimental results show that this improvement can be attributed to the removal of oxygen from PE. We also observed in detail the processes of tree initiation and growth in the degassed samples. The observations, with other results, led us to conclude that the charge carriers injected from the point electrode play a dominant role in the tree initiation.
