摘　　要：介绍了复合浓度型油中溶解气体在线监测仪(dissolved gas-in-oil analyzer of composite concentration,DGA)的结构特点及其应用,并结合实际运行与离线色谱分析数据,从监测仪的优缺点、准确性、运行可靠性和维护成本等方面进行分析,得出复合浓度型在线监测仪对故障反映不及时、测量数据不准确、不能进行故障类型判断、通信方式不合理、故障率高且维修成本大的结论。This paper introduces structural characteristics and application of dissolved gas-in-oil analyzer of composite con- centration. Combining practical operational and off-line chromatographic analysis data, it analyzes merits and demerits, ve- racity, operational reliability and maintenance cost of the analyzer and draws conclusions for the analyzer such as untimely reflection on fault, incorrect measuring data, being unable to judge fault types, unreasonable communication modes, high fault rate and big maintenance cost.
