Description

Technical Field

[0001] This utility model belongs to the technical field of transformer clamp and pull plate connection structure, specifically relating to a transformer clamp and pull plate connection structure. Background Technology

[0002] The transformer core is made of stacked silicon steel sheets, and clamps securely fix the core in its position. For example, in a three-phase transformer, the core columns and yoke need to maintain precise relative positions. The clamps prevent displacement of the core due to electromagnetic forces or other factors during operation by clamping the various parts of the core. This is like a frame that tightly holds the loose core in place, ensuring its stability.

[0003] Tie plates are primarily used to enhance the mechanical strength of transformers. During transformer operation, especially under short-circuit conditions, the windings are subjected to enormous axial forces. Tie plates, in conjunction with clamps, can evenly distribute these axial forces throughout the transformer structure, preventing transformer vibration.

[0004] During long-term operation, bolts may loosen due to transformer vibration. Once the bolts loosen, the connection between the clamps and the tie plates weakens, making it unable to effectively transmit and withstand mechanical forces. This can lead to displacement of the clamps and tie plates, affecting the normal operation of the transformer. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content
