一起变压器油枕油位异常的处理

Treatment of Abnormal Oil Level of a Transformer Oil Pillow

变压器油枕油位是变压器运行的重要监视参数,变压器油位过高,会增加变压器内部的压力,引起变压器压力释放阀动作而喷油;变压器油位过低,不仅会使变压器高压套管油位降低,易导致套管内部放电而发生事故,还会造成变压器内部铁芯线圈散热不良,引起过热,严重时会烧毁变压器。介绍了油浸变压器油枕的结构、作用以及工作过程,对一起油浸变压器油枕油位异常升高的原因进行了分析及处理,对于油浸变压器的运行维护有借鉴意义。

The oil level of transformer oil pillow is an important monitoring parameter of transformer operation. If the oil level of transformer is too high,it will increase the pressure inside the transformer and cause the pressure relief valve of transformer to act and spray oil.If the transformer oil level is too low,it may not only make high voltage bushing oil level of the transformer reduced,which may easily lead to the discharge inside the bushing and even accidents,but also may cause poor heat dissipation of the inner core coil of the transformer,resulting in overheating. In the most serious case,the transformer may even be burnt down. The structure,function and working process of oil-immersed transformer oil pillow are introduced,the reason of abnormal rise of oil level of oil-immersed transformer oil pillow is analyzed and handled,which is of reference significance for the operation and maintenance of oil-immersed transformer.
