摘　　要：交联聚乙烯 (XLPE)电缆绝缘老化自动检测系统采用直流成分法、直流叠加法和补偿电势法三种方法 ,可对运行中的XLPE电缆主绝缘状况和护套破损情况进行可靠、有效的现场在线监测 ,并实现对XLPE电缆绝缘老化状况的快速评估。介绍了该系统所采用的抗干扰技术及系统构成。A automatic system for online XLPE cable insulation diagnosis is designed in this paper. It is a system which can make reliable,overall surveillance of hotline XLPE cable main insulation deterioration and sheath insulation damage, also can quickly access the deterioration of XLPE cable insulation. This system adopts three detecting methods: DC component method, DC superposition method, compensating potential method. In this paper, the anti interference technique used and the frame of this system are also introduced.
