气隙对环氧树脂绝缘材料电树枝实验的影响

摘要

This article introduces the fabricating methods of the insulating base and the needle-plate discharge model in epoxy electrical tree experiment,and analyses the influence of air gap on electrical tree experiment. Combining with the experiment result,the failure mechanism of air gap on insulation properties of epoxy resin material is expounded.%介绍了环氧树脂电树枝实验中绝缘基座和针—板放电模型试样的制作方法，并引入气隙进行了电树枝实验，结合实验结果进行分析，阐述了气隙对环氧树脂材料绝缘性能的破坏机理。
