摘要
水树枝劣化是导致交聚乙烯(XLPE)电力电缆绝缘水平下降和寿命缩短的主要诱因。本文介绍了水树的定义、特征、影响因素及潜在危害等,阐述了XLPE电缆水树劣化的原因,分析并对比水树劣化的各种诊断方法。最后,针对XLPE电力电缆水树劣化提出了有效的绝缘修复技术,为今后XLPE电力电缆水树劣化的诊断和修复技术提供一定的参考方向。
The degradation of water tree is the main reason for the decrease of insulation level and the shortening of service life of XLPE power cable.This paper introduces the definition,characteristics,influencing factors and potential hazards of water tree,ex⁃pounds the causes of XLPE cable water tree degradation,analyzes and compares various diagnostic methods of water tree degrada⁃tion.Finally,an effective insulation repair technology for XLPE power cable water tree degradation is proposed,which provides a certain reference direction for the diagnosis and repair technology of XLPE power cable water tree degradation in the future.
