摘　　要：过去，对交联聚乙烯（ＸＬＰＥ）电缆的故障诊断采用停电后施加直流耐压来进行，这种方法可能因破坏绝缘而损伤电缆．为此，上海电缆研究所和宝钢合作研制成功一种既能在线诊断，又不损伤电缆绝缘的仪器．文中对该仪器作了介绍．In the past accidents of XLPE cables were inspected by exerting DC voltage on the cables after outage. This method would damage the cables due to destruction of insulation. In order to solve this problem an on-line inspecting instrument was successfully developed by Shanghai Cable Institute and Baoshan Iron and Steel Company. The instrument will not damage cable insulation during inspection. The instrument is presented in this paper.
