The assembly process and structure of transformer cores must be designed around electromagnetic performance and mechanical stability. The core structure uses laminations as the basic unit, forming a closed magnetic circuit through staggered stacking. The treatment of lamination joints must meet the requirements of reluctance control to avoid magnetic flux loss. The clamping structure must apply pressure evenly to maintain the overall compactness of the core, preventing structural loosening caused by vibration during operation. The grounding structure must ensure a reliable connection between the core and the casing to suppress eddy currents and guarantee operational safety.
The assembly process needs to be implemented step-by-step in conjunction with structural characteristics. During the lamination process, the direction and sequence of the sheets must be strictly controlled to ensure magnetic circuit continuity, and the gap between laminations must be kept within a reasonable range to avoid affecting magnetic performance. In the clamping stage, an appropriate clamping method must be selected to distribute the clamping force evenly, preventing local stress concentration from causing deformation of the laminations. The installation of the grounding device must be compatible with the core structure to ensure the conductivity of the grounding path and avoid the formation of floating potentials.
