摘要
本文介绍了交联聚乙烯 ( XL PE)电树枝老化的试验方法 ,给出了 XL PE绝缘在交流电压作用下的电树老化曲线。利用多元统计分析建立了枝状放电、丛状放电的数学模型 ,为 XL
This is a paper deals with an experimental study on electrical tree aging process in XLPE cable insulation.The aging curve of electrical tree subjected to AC voltage is presented.Mathematical model of branch type tree and bush type tree are founded with multivariate statistical analysis,which provides theoretical basement for on line monitoring of XLPE cable.
