英文摘要: An apparatus is designed and evaluated for the determination of the Ostwald coefficient of gases dissolved in transformer oil. It consists of a water bath with magnetic stirring, balance flask, six-port valve and an on-line gas chromatography. The balance time and Ostwald coefficient of hydrocarbon gases including CH,, C-2 H-2, C2H4, C2H6 and C3H8 dissolved in transformer oil were determined at 20° C and 50° C, respectively. The error of repeatability of 8 measurements is less than 1. 2% ( RSD). It provides fundamental data for online measurement of dissolved gases in transformer oil by gas chromatography.
