摘要

绝缘材料的空间电荷积累和空间电荷分布的研究在材料研究领域变得越来越重要。带二氧化钛填料的聚碳酸酯(PCTiO/sub 2/)是一种绝缘材料，在许多应用中与绝缘油结合使用。因此，对空间电荷形成的检查应包括绝缘油的影响。为此，空间电荷测量是在没有任何油的PCTiO/sub 2/样品和在油中储存一段时间的样品上进行的。观察到空间电荷密度的差异。为了证实油对固体介质的渗透，使用了极化电流测量和热重法。

Influence of insulating oil on space charge formation and electrical threshold in polycarbonate with inorganic filler

Examination of the space charge accumulation and space charge profile of insulating materials is becoming increasingly important in the field of material research. polycarbonate with titanium dioxide filler (PCTiO/sub 2/) is an insulating material, which in many applications is used in combination with insulating oil. Therefore, examination of the space charge formation should include the influence of the insulating oil. For this purpose space charge measurements were made on PCTiO/sub 2/ specimens without any oil and on specimens that were stored in oil for some time. Differences in the space charge densities were observed. To confirm the penetration of the oil into the solid dielectric, polarisation current measurements and thermogravimetry were used.
