Description

Mutual inductor fixing structure and mutual inductor Technical Field The utility model relates to the technical field of transformers, in particular to a transformer fixing structure and a transformer. Background At present, the existing through type current transformer fixing mode generally adopts a mode that a copper bar passes through a central window of the transformer, and a screw fixed on the transformer tightly pushes against the copper bar to fasten. The fastening scheme can meet the installation and fixation requirements of domestic products, and for products coming out of sea, the current fastening scheme cannot meet the requirements of different installation positions and poor scene applicability because the screw length is insufficient for fastening the mutual inductor and the copper bar, and the current fastening scheme cannot meet the requirements of different installation positions because the mutual inductor and the copper bar are simply fastened by the screw due to the fact that the screw is only pressed against the copper bar by the screw in the axial direction to limit the copper bar for the products coming out of sea. Therefore, a fixing mode with higher fastening degree and flexible installation is needed to meet the fixing requirement of the through type current transformer.
