摘要/Abstract

摘要： 用气相色谱法分析绝缘油中溶解气体来检测充油电气设备内部故障是国内、外极为重视的一项工作。采用变压器油中溶解气体的分析技术，是依据变压器油中气体所包含的组分和含量对变压器有无故障进行判断，进一步分析出变压器的故障类型、大体的故障部位、故障的严重程度以及故障的发展趋势，并据此提出具有针对性的防范措施，实现不停电检测和故障诊断，减少变压器故障发生的几率，对安全生产具有重要的指导意义

关键词: 变压器油, 溶解气体, 在线检测, 故障判断

Abstract: It is very important at home and abroad to detect the internal fault of oil filled electrical equipment by analyzing the dissolved gas in insulating oil with gas chromatography. The analysis technology of dissolved gas in transformer oil is used to judge the transformer failure according to the components and content of the gas in transformer oil, the fault type, general fault location, fault severity and fault development trend of the transformer are further analyzed, and some targeted preventive measures are accordingly put forward, so as to realize online detection and fault diagnosis and reduce the probability of transformer failure. It provides guidance for safe operation.

Key words: transformer oil, dissolved gas, online detection, fault diagnosis
