摘　　要：针对10 kV XLPE(交联聚乙烯)电缆常见绝缘故障,在试验室制作了5种典型的中间接头绝缘缺陷物理模型。采用高频电流法获取了不同绝缘缺陷模型下的大量局部放电数据,形成了典型局部放电图谱。试验表明,利用高频电流法检测10 kV XLPE电缆的局部放电可行、有效。In consideration of the common insulation faults of 10 kV XLPE cable , five typical physical mod-els of intermediate joint insulation faults are made in the laboratory. Through high frequency current method, partial discharge data in different insulation fault models are obtained to form typical partial discharge dia-grams. The test indicates that high frequency current method is feasible and effective to test partial discharge of 10 kV XLPE cables.
