| 摘 要： | 通过对交链聚乙烯（ＸＬＰＥ）电力电缆试品的工频、０．１Ｈｚ超低频和振荡３种击穿电压的平行比对试验研究，探讨能够有效发现、判别ＸＬＰＥ电力电缆运行故障隐患的试验方法，试验研究结果表明：振荡波电压试验能够有效地发现电力电缆及其附件的制造和安装质量缺陷，超低频电压试验能够有效地发现电力电缆及其附件绝缘树枝状早期劣化缺陷；工频电压试验是一种较好的方法，需进一步深入研究。

| Abstract: | Three test methods for detecting the insulation defect of the XLPE power cable line, i.e., 50Hz AC voltage, 0.1Hz very low frequency voltage (VLF) and oscillating wave voltage (OWV), are compared. The experimental results show that 50Hz AC test is a preferable method to detect the defects in various types of XLPE power cable but the practicable technology needs further research. It is confirmed that 0.1Hz VLF test is quite effective in detecting moisture and water treeing in the XLPE power cable including accessories. OWV test is effective in detecting defects formed in manufacture and installation process of XLPE cable. |
