摘要
油中溶解气体分析(又称油色谱分析)是诊断充油电气设备内部故障的重要技术手段.对油中溶解气体分析技术的原理和方法进行了介绍,并通过某 110 kV变电站 10 kV油浸式电抗器内部放电故障处理与分析,来验证油中溶解气体分析可为充油电气设备故障和潜在故障识别及故障类型判断提供有力的技术支撑,有效保障电网的安全稳定运行.
Abstract
Analysis of dissolved gas in oil(also known as oil chromatography)is an important technical means to diagnose internal faults of oil-filled electrical equipment.The principle and method of dissolved gas in oil analysis technology are introduced.Through the fault treatment and analysis of internal discharge of 10 kV oil-immersed reactor in a 110 kV substation,the analysis of dissolved gas in oil can provide strong technical support for fault and potential fault identification and fault type judgment of oil-filled electrical equipment,and effectively ensure the safe and stable operation of the power grid.
