摘要
本文在分析固体有机介质中水分解吸挥发规律及介电特性的基础上,提出了纸绝缘干燥过程中电容量随时间变化的数学模型,建立了一种新的干燥过程中实时无损检测微量水分的方法,这种方法适用在1000ppm数量级并与解吸色谱法相吻合。
The paper used in oil-paper insulation systems must be throughly dried prior to oil impregnation.A mathematical model relating dielectric properties and moisture content of paper during the drying process is proposed inthis paper. Then a measuring method to determine the moisture contem in time during the drying process is des- cribed. This method is suitable for use for water content of 1000ppm, and the res ultsobtained agree well with those obtained by desorption- chroma-tography.
