This invention discloses a transformer lead fixing device with deformation self-compensation function, relating to the field of transformer technology. The invention includes a fixing plate fixed to the transformer housing, a lead fixing component, a deformation self-compensation mechanism, and a pin mechanism. The deformation self-compensation mechanism includes a clamping component fixed to the end of the lead and multiple stops disposed on the fixing plate. The clamping component has a multi-segmented bent elastic structure, and the stops have inclined abutment surfaces. The pin mechanism adjustably mounts the lead fixing component to the fixing plate. When the lead fixing component is driven to move closer to the transformer housing, the clamping component and the inclined abutment surfaces of the stops abut against each other, generating elastic deformation and achieving electrical contact between the clamping component and the terminal block. This invention, through the multi-segmented bent elastic structure of the clamping component and the unidirectional displacement adjustment of the pin mechanism, achieves adaptive compensation for deformation caused by thermal expansion and contraction and vibration, ensuring long-term stable electrical contact between the terminal block and the lead, and facilitating subsequent maintenance and adjustment.
