摘要
本文旨在阐述用快速宽频带测量系统及影视技术对交联聚乙烯绝缘材料中树状放电的试验方法。证明有丛状放电和枝状放电两种形式。给出两种放电形式的不同特征。通过测量放电脉冲参数的变化,研究树状放电的机理。从而提供探索固体有机绝缘材料老化过程检测的新途径。
The paper describe an experimental method of electrical trees in polyethylene using wide-band PD detector and video techniques. Brush tree and branched tree have demonstrated. In the paper the features of two type trees have been given. By measurements of waveform parameters of PD pulses, the new way related to exploring the mechanism of electrical treeing as well as monitoring the ageing of polymetric insulation can be found.
