Transformer visual fault diagnosis method and system based on refined three-dimensional model

The invention discloses a transformer visual fault diagnosis method based on a refined three-dimensional model. The method comprises the following steps: acquiring physical data and operation data of a target transformer; establishing a refined three-dimensional model of the transformer according to the physical data of the target transformer, and adding a fault processing guidance library and a fault diagnosis algorithm library in the refined three-dimensional model of the transformer; performing visual design on the transformer refined three-dimensional model of the fault processing guidance library and the fault diagnosis algorithm library to obtain a transformer refined three-dimensional model with a visual interface; according to the operation data of the target transformer, using the transformer refined three-dimensional model with the visual interface to carry out real-time visual fault diagnosis; a fault diagnosis algorithm and a fault processing guidance library are built in the system, so that the q
