Insulating liquids - Quantitative determination of methanol and ethanol in insulating liquids 绝缘液体.绝缘液体中甲醇和乙醇的定量测定
发布日期: 2021-07-12
IEC TR 63025:2021(E)规定了绝缘液体中甲醇和乙醇测定的两种测试方法。 甲醇(MeOH)和乙醇(EtOH)是纤维素材料降解过程中产生的两种轻质醇。它们可溶于绝缘液体,因此它们可以被视为老化示踪剂,其在油中的浓度反映了液体浸渍变压器中绝缘纤维素材料的降解。
IEC TR 63025:2021(E) specifies two test methods for methanol and ethanol determination in insulating liquids.
Methanol (MeOH) and ethanol (EtOH) are two light alcohols generated during the degradation process of cellulosic materials. They are soluble in insulating liquids so they can be regarded as ageing tracers whose concentrations in oil reflect the degradation of insulating cellulosic materials in liquid-impregnated transformers.
