Abstract:

提出了一种在水树通道内自生成纳米SiO2复合填充物的电缆修复液,并将其修复效果与先期纳米修复液作了对比。采用水针电极法加速交联聚乙烯(XLPE)电缆绝缘水树老化,利用两种不同成分的纳米修复液对老化电缆样本进行修复。介质损耗和工频击穿电压测试结果表明,该新型修复液修复后样本绝缘性能提升更大。对修复前后的水树样本进行显微镜观测,证实了生成物对水树通道的填充效果。通过对修复液与水直接反应生成物和电缆样本击穿通道进行扫描电镜(SEM)分析,可看到新型修复液生成的纳米SiO2粒径更小,修复后电缆样本击穿通道内部的无机纳米颗粒团聚程度更低,分布更均匀。基于以上发现,证明了该新型修复液能够在水树通道内自生成纳米SiO2复合填充物,且修复效果优于先期纳米修复液,并提出了偶联剂界面连接模型对实验结果进行了解释。
