摘要

本文研究了层状密度的交联聚乙烯(XLPE)绝缘材料的介电强度随添加剂和固化条件的变化规律。为了提高交联聚乙烯绝缘材料的层状密度，采用了两种添加剂，并控制冷却速度作为固化条件。利用透射电镜和x射线衍射研究了添加剂对层状密度的影响程度。针对掺加添加剂和不同冷却速率的交联聚乙烯绝缘的击穿强度，制作了模具型电缆试样，并用威布尔图参数对其进行了评价。结果表明，添加剂提高了层状密度。此外，我们发现在慢冷却速率下制备的样品的介电强度高于快速冷却速率下制备的样品。TEM和XRD分析表明，界面处XLPE绝缘材料的密度对XLPE绝缘材料的介电强度有显著影响。

Improvement of breakdown strength by additives and curing conditions on XLPE insulation for power cable

In This work, dielectric strength of XLPE insulation with lamellar densities varied by means of additives and curing conditions was investigated. To increase lamellar density of XLPE insulating material, two kinds of additives were used and cooling rates were controlled as curing conditions. TEM and X-ray diffraction was used to investigate the degree of lamellar density varied by additives. For breakdown strength of XLPE insulation with additives and different cooling rates, the mold-type cable specimens were made and evaluated with Weibull plot parameter. From the results, it is observed that the additives improve the lamellar density. In addition, we found that the dielectric strength of samples manufactured under slow cooling rate is higher than rapid cooling one. TEM and XRD analysis showed that the density in the XLPE insulation at the interface significantly affects dielectric strength of XLPE insulation.
