摘要
通过大量样品实验研究,本文发现,在同等实验条件下,由于材料聚集状态的差异,在同一XLPE电缆绝缘中引发和生长的电树枝可分为枝状、丛林状、藤枝状、松枝状和混合状等五类;不同结构的电树枝对高压XLPE电缆运行可靠性的影响不同;对产生这几种电树枝结构的内在材料聚集状态特征进行了研究。
In this paper it is found by large number samples of experimental studies that there are five types of electrical trees in XLPE cable insulation. The electrical trees can be divided into branch type, bush type, pinetree branch type, binebranch type and complex type. The shape of electrical tree is decided by experiment situation and material situation. The influence of material situation, such as residual mechanical stress and crystalloid state, to the shape and growing properties of electrical trees is main research target in this paper.
