摘要

交联聚乙烯（crosslinked polyethylene

XLPE）绝缘电力电缆在经过长时间运行后会发生水树老化

降低电缆绝缘强度

威胁电力系统的安全稳定运行。笔者设计了一套XLPE电缆绝缘水树修复装置

利用硅氧烷修复液对电缆试样进行了修复工作

详细介绍了修复过程并深入分析了修复机理。然后仿真对比了修复前后不同类型水树区域的电场变化

测试了修复后电缆介质损耗角正切与绝缘电阻的变化趋势

接着对电缆进行了加速水树老化实验

利用光学显微镜观察老化后XLPE绝缘中的水树生长情况。研究表明:修复液与水能快速反应产生聚合物填充水树孔隙

逐步提升电缆整体绝缘性能;生成物的介电性能与XLPE接近

能显著改善水树区域特别是尖端的电场

抑制水树的进一步生长

有效延长电缆使用寿命。

Abstract

The safe and stable operation of power system will be threatened because of the water tree aging of XLPE cables after years of running. In this paper

a rejuvenation system for XLPE cables is designed and a field aged cable specimen is restored via this system

making use of rejuvenation fluid based on siloxane. Moreover

the cable rejuvenation process is introduced in detail and the rejuvenation mechanism is analyzed in deep. Furthermore

electric field change

dielectric loss factor and insulation resistance of the specimen before and after rejuvenation is simulated as well as tested. Then the growth of water tree in the restored specimen is observed by optical microscope after accelerated water treeing test. The results show that insulation performance of restored cables is improved since the micro voids is filled with resultant created by the reaction of rejuvenation fluid and water. In addition

the growth of water tree is restrained as the resultant is closed to XLPE in dielectric properties

which results in the extending lifetime of cables.
