Transformer oil paper insulation aging microstructure observation system and method

The invention provides a transformer oil paper insulation aging microstructure observation system and method. The method comprises (1) immersing pre-treated transformer oil paper in pre-treated insulating oil and conducting drying and degassing in a vacuum environment; (2) placing the insulating oil and the transformer oil paper obtained in the step (1) in a sealed aluminum can for sealing according to a certain mass ratio, and then placing the sealed aluminum can in a high temperature drying unit to perform long-term heat aging on the transformer oil paper; (3) deoiling and drying the transformer oil paper aged in the step (2); (4) performing microstructure observation on the transformer oil paper dried in the step (3). According to the system and the method, the insulation aging condition and the service life of a transformer can be accurately evaluated in a shorter time, and the damage to the transformer is also small. Therefore, the system and method can better guide the actual engineering. 本发明提供了种变压器油纸绝缘
