摘要
活化能是反映变电设备干式绝缘材料老化程度的关键指标。文章研究热失重法和介电谱法两种获取活化能的方法,分析两种方法的检测原理,为干式绝缘材料老化检测提供基础。
Activation energy is a key index to reflect the aging degree of dry insulation materials for substation equipment.In this paper,two methods to obtain activation energy,namely thermogravimetric method and dielectric spectroscopy method,are studied.The detection principle of the two methods is analyzed,which provides the basis for the aging detection of dry insulation materials.
