摘要
为了给交联聚乙烯电缆水树老化状态的检测和与监测技术奠定基础,针对XLPE电缆水树在线检测常用的3种方法(直流分量法、损耗角正切法、谐波分量法)进行了计算机仿真模拟,比较了3种方法的优劣。建议采用测损耗角正切与测谐波分量相结合的方法,全面分析判断电缆水树老化状态。
In order to lay a foundation for testing and supervising the ageing status of stranded polyethylene electric power cable water tree,computer simulations were made for the three methods commonly used for on-line testing of stranded polyethylene cable water tree,DC component,tan δ,and harmonic component,and these three methods were compared for advantages and disadvantages.It is recommended to combine the tan δ method with the harmonic component method and run a comprehensive analysis of the ageing of cable ageing.
