摘要

采用红外光谱法研究了绝缘油中水分的状态。结果表明，材料中存在多种类型的水团簇:单体(H/sub 2/O)、二聚体(H/sub 2/O)/sub 2/、三聚体(H/sub 2/O)/sub 3/和聚合物(H/sub 2/O)n。在电应力作用下，施加不同的电场会改变水的状态。二聚体状态对导电无影响，而三聚体在含水量较高时对导电有促进作用

Effect of dissolved water on electrical conduction in dielectric liquid

The state of water in insulating oils was studied using infrared ray spectroscopy. It was found that there are many kinds of water clusters in the materials: monomer (H/sub 2/O), dimer(H/sub 2/O)/sub 2/, trimer(H/sub 2/O)/sub 3/, and polymer(H/sub 2/O)n. Under electrical stress, the states of water were changed by applying different electrical fields. The dimer state had no effect on the conduction, whereas trimer contributed to the conduction when the water content was higher.<>
