《GB/T 7252-2001变压器油中溶解气体分析和判断导则》由524（中国电力企业联合会）归口，主管部门为中国电力企业联合会。
本标准推荐了利用油中溶解气体和自由气体浓度分析，判断充油电器设备状况的方法以及建议应进一步采取的措施。本标准适用于充有矿物缘油和以纸或层压纸板为固体绝缘材料的电气设备，其中包括变压器、电抗器、电流互感器、电压互感器和油纸套管等。分析结果的结论要结合设备的结构、检修、电气试验、运行状况以及当时、当地的环境条件等进行综合判断。

Scope

This standard recommends the method of judging the condition of oil-filled electrical equipment by analyzing the concentration of dissolved gas and free gas in oil, and recommends further measures to be taken. This standard applies to electrical equipment filled with mineral insulating oil and paper or laminated paperboard as solid insulating material, including transformers, reactors, current transformers, voltage transformers and oil-paper bushings, etc. The conclusion of the analysis results should be comprehensively judged in combination with the structure, maintenance, electrical test, operation status of the equipment, and the current and local environmental conditions.
