摘　　要：设计了一套以气相色谱测定变压器油中溶解气体奥斯特瓦尔德系数的装置。它包括恒温水浴、磁力搅拌器、油气平衡瓶、六通阀以及在线气相色谱仪。测定了20℃和50℃温度下变压器油中溶解气体CH4、C2H2、C2H4、C2H6 和C3H8 的奥斯特瓦尔德系数和平衡时间,测量的重复性误差RSD小于1. 2%。为气相色谱在线分析变压器油中溶解气体积累了重要的基础数据。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.
