| 摘 要： | 通过研究发现，在对ＸＬＰＥ电缆施加超低频方波的同时，再叠加一定大小的工频电压，使含有水材老化电缆绝缘的响应电流波形产生显著畸变，而对比空白电缆样品的响应电流波形基本不变；本文同时对这种叠加效应的产生机理进行了探讨。这种方法有可能发展成为ＸＬＰＥ电缆离线检测的有效手段。

| Abstract: | It is found that when a superposition voltage ofultra-low square-wave and power frequency is applied to thewater treeing insulation of XLPE cable, the response current wave shape is greatly different from that of one withoutwater treeing.The formation mechanism of superpositionresponse is discussed in this paper. The method of superposition response could be developed to an efficiency means foroff-line diagnosis of XLPE cable insulation |
