摘　　要：中压交联聚乙烯(XLPE)电缆系统(电缆附件)故障,大多归因于生产制造和安装工艺不当导致的局部缺陷。介绍安装工艺不当导致的接头缺陷,并在试验室内实际制作了7种35 kV XLPE电缆接头人工缺陷,获取了其典型放电谱图,为在线检测放电谱图的诊断提供了缺陷样本数据。The faults of the medium voltage cross-linked polyethylene（XLPE） cable system（cable accessories） are mostly attributed to the partial defects caused by the production manufacturing and the improper installation technology.The joint defects caused by the improper installation technology were described,seven kinds of 35 kV XLPE joints artificial defects were made in the laboratory,and typical discharge maps were obtained.This provided the defects sample date for the diagnosis of the on-line detected the discharged map.
