This standard deals with the determination of the aromatic hydrocarbon content of new mineral insulating oils. Two methods are proposed: — Infrared spectrophotometric analysis This method is recommended as a quality control and acceptance test for mineral insulating oils. It uses the relationship between the absorbance at 1 610 cm- 1 and the n-d-M analysis * to determine the proportion of the total carbon atoms present in aromatic ring structures. The conversion factor derived from this relationship is applicable to oils with a molecular mass in the range 290 to 500 and with an aromatic carbon content in the range 1.2 % to 60%. — Adsorption chromatographic analysis This method describes the measurement of the percentage by mass of polar compounds and compounds containing at least one aromatic ring per molecule present in low molecular mass mineral insulating oils.
4、下表列举了几种样品测芳碳含量测试结果: · 结论采用红外光谱法测定矿物绝缘油、润滑油结构族组成,结合DL/T 909-2005中的经验公式,可以方便、快速、准确地确定矿物绝缘油、润滑油的结构族组成。...
矿物绝缘油是从石油中提炼精制的液体绝缘材料,简称矿物油。石油的主要成分是烷烃、环烷烃和芳香烃,这些组分的电气性能和老化稳定性优良。环烷基原油因含蜡量较少,可用来制造低凝固点绝缘油,又因含芳香烃组分较多,在电场作用下不但不析出气体,还吸附气体,故多以它制造绝缘油。环烷基原油在世界上储量少,现正研究以石蜡基原油制造绝缘油。原油中还含有树脂质、沥青质及少量氧、氮、硫等元素的化合物。...
