On-load tap-changer state detection method, device and equipment and storage medium

The invention discloses an on-load tap-changer state detection method, device and equipment and a storage medium, and aims to acquire three-axis vibration signals of an on-load tap-changer, acquire multiple axial vibration signals, increase acquired effective information and improve the accuracy of state detection. And then, denoising processing is performed on the three-axis vibration signals, so that the accuracy of the vibration signals participating in subsequent processing is ensured. Then, the denoised three-axis vibration signals are input into a multi-vibration sensing information fusion network for training, a multi-vibration sensing information network model and feature-fused three-axis vibration signals are obtained, and the multi-vibration sensing information fusion network can fuse vibration signal feature values with other axial features; a vibration signal with both depth and breadth is provided. And finally, inputting the feature-fused three-axis vibration signal into the multi-vibration sensi
