摘　　要：变压器是电力系统的重要组成部分,一旦发生故障就会对电力系统供电的稳定性造成严重影响。35 kV油浸电力变压器是当前应用最为广泛的变压器类型,其在运行过程中主要面临的故障包括热干扰性质故障、电气干扰故障、人为故障以及重瓦斯保护措施4种类型。在实际故障诊断分析中,需要根据实际情况合理判断故障类型,并针对性采取预防性检修策略、故障分类检修策略或变压器在线检修策略,以便有效解决变压器故障,保证电力系统的高质量运行。Transformer is an important part of the power system,once the failure of the power system power supply stability caused serious impact.35 kV oil-immersed power transformer is currently the most widely used type of voltage apparatus,its main faults in the operation process include thermal interference faults,electrical interference faults,man-made faults,and heavy gas protection measures of four types.In the actual diagnosis and analysis of faults,it is necessary to reasonably determine the type of faults according to the actual situation,and target to take preventive maintenance strategy,fault classification maintenance strategy or transformer online maintenance strategy,in order to effectively solve the transformer faults,to ensure the high quality of the operation of the power system.
