| 摘 要： | 为了解聚乙烯和交联聚乙烯电缆水树老化机理，并为电缆水树老化状态的检测与监测技术奠定实验和理论基础，对聚乙烯和交联聚乙烯片状试样进行了水树老化实验，研究了交联聚乙烯和聚乙烯片状试样老化前后损耗角正切tanδ及损耗电流I与外施电压V的关系变化。结果表明，老化后损耗角正切随外施电压的变化而变化，且损耗电流与外施电压的关系呈现非线性。

| Abstract: | In order to understand water tree aging mechanism of PE cables and XLPE cables and ground technology of diagnosis water tree of cables in experiment and theory, experiments of water tree aged PE and XLPE slice are carried out. In this paper, the relationships between loss and voltage, loss current and voltage of water tree aged PE and XLPE slice are studied.And it is found that loss changes vs varied voltages and the relation between loss current and voltage is nonlinear when PE and XLPE slice are water tree aged. |
