摘要

在低密度聚乙烯及其填充1.0 wt%和3.0 wt%氧化铝纳米颗粒的纳米复合材料中，观察到在直流预应力下，随后施加极性相反的电压脉冲形成电树。为测试制造了一种特殊的线平面电极几何形状。实验结果表明，纳米颗粒的加入对电树的电阻有积极的影响。除了上述报告的结果外，目前正在进行热老化和电热实验，并将给出实验后树形行为的比较结果。

Electrical treeing in polyethylene-alumina-filled nanocomposites for HVDC applications

Electrical tree formations under DC pre-stress followed by an application of voltage pulses of opposite polarities were observed in low density polyethylene and its nanocomposite filled with 1.0 wt% and 3.0 wt% alumina nanoparticles. A special wire-plane electrode geometry were manufactured for the test. The obtained experimental results indicate that the addition of the nanoparticles has a positive impact on the resistance to electrical treeing. In addition to the reported above results, a thermal ageing and electro-thermal experiment is presently being conducted and the results comparing the treeing behavior after it will also be presented.
