基于交联聚乙烯（XLPE）电缆水树状老化的原理，直流分量法和交流叠加法是两种有效的XLPE电缆在线监测方法。设计了综合上述两种方法的在线监测系统，其中包括设计方案、系统构成、关键技术等。结果表明：设计的XLPE电缆在线监测系统能够反映运行中电缆绝缘的老化程度，实现了XLPE电缆的在线监测。
Based on the theory of water tree ageing of XLPE cable, the DC component method and AC superposition method are effective methods for on-line monitoring of XLPE cable. An on-line monitoring system of XLPE cable based on the above two methods was designed, which included design plan, system construction, and key technology. The experiment results show that the on-line monitoring system can reflect the ageing degree of the running cable, and realize the on-line monitoring of the cable.
