摘要
交联聚乙烯(XLPE)电缆的绝缘状态关系到输电系统的安全运行,因此,研究电缆绝缘的老化方式、状态监测和诊断方法意义重大。本文首先介绍了XLPE电缆绝缘的老化方式和老化机理;随后总结了电缆绝缘的状态监测方法,包括利用绝缘材料的理化性质和特征响应性实现电缆绝缘的状态监测;最后讨论了电缆绝缘老化的修复方法和预防措施。
The insulation condition of cross-linked polyethylene(XLPE) cables concerns the operation safety of power transmission systems. Therefore, it is of great significance to study the ageing methods,condition monitoring, and rejuvenation technologies of cable insulation. In this paper, the ageing methods and mechanism of XLPE cable insulation were introduced at first. And then the monitoring methods of cable insulation condition were summarized, including using the physicochemical properties and characteristic responsiveness of insulating materials to realize the insulation condition monitoring. At last, the rejuvenation technologies and prevention measures of aged cable insulation were discussed.
