摘　　要：对用于配电电网的交联聚乙烯(XLPE)电力电缆绝缘在线监测技术的研究现状进行了回顾,对各种在线监测技术的技术特点和问题作了分析比较,包括直流分量法、直流电压叠加法、电桥法、交流叠加法、低频叠加法、损耗电流测量法、接地线电流测量法及局部放电法。探讨了XLPE电力电缆绝缘在线监测技术的发展方向。The on-line monitoring techniques for XLPE power cable in distrbution network are reviewed. Their characteristics and problems are analyzed and compared,including DC component method,DC voltage superimposition method,bridge method,AC superimposition method,low frequency superimposition method,loss current measurement method,grounding current method and partial discharge method. The development trend of the on-line monitoring technique for XLPE power cables is discussed.
