摘要

对绝缘子中的脉冲树进行了三维测量，以研究其发展机制。由于通常观察到的树是平面上的投影树，因此投影树具有假分支，其分支的方向并不精确。本文利用CT(计算机断层扫描)方法对聚合物绝缘体(PMMA)中的脉冲树进行了三维测量。连续施加脉冲电压。在每一步中，都测量了树和树的属性，这些属性是投影树无法获得的，比如截面。得到了两个极性下分支的体积和分布

Development of tree in polymeric insulator applied successive impulse voltages and its three-dimensional measurement

Impulse trees in insulators have been measured three-dimensionally to investigate their development mechanism. Since a usually observed tree is a projected one on the plane, the projected tree has pretend branches and the directions of its branches are not exact. In this paper, the impulse trees in the polymeric insulator (PMMA) have been measured three-dimensionally utilizing a CT (computer tomography) method. Successive impulse voltages have been applied. In each step, the tree has been measured and also the properties of the tree which cannot be obtained by the projected tree, such as the cross section. The volume and the distribution of the branches have been obtained for both polarities.<>
