A three-phase five-column amorphous alloy transformer core structure and manufacturing method thereof

Abstract

The invention relates to a three-phase five-column amorphous alloy transformer iron core structure and a manufacturing method thereof and belongs to the technical field of production of transformers. The technical scheme includes that a plurality of iron core frames are combined together through resin adhesives to form a three-phase five-column iron core structure, the three-phase five-column iron core structure is adhered to a transformer iron core pulling plate to form an integrated structure, the iron core frames are clamped by two upper clamping pieces and two lower clamping pieces, clamping insulation pieces which are manufactured by insulation rubber plates are arranged between the upper clamping pieces and iron core frames and between the lower clamping pieces and iron core frames, the upper clamping pieces and the lower clamping pieces are manufactured by steel structures and fastened by sideward screws, and a transformer base foot pad bracket is used as a support of a transformer. The transformer iron core pulling plate supports an iron core, the plurality of iron core frames are adhered together through the resin adhesives, core columns are bound by weftless glass adhesive tapes to form a firm integrated structure, the iron core is not required to be turned over, and the length of an amorphous sheet of an iron yoke opened by the iron core before a coil is sleeved is reduced so that the iron yoke is easy to treat after the iron yoke is opened, and technological processes are simplified.

Problems solved by technology

[0002] At present, in the manufacture of amorphous alloy transformers, the background art amorphous alloy iron core is composed of independent small iron core frames, and each iron core frame needs to be combined together before the transformer coil is assembled, and then fixed by binding or other methods. Due to manufacturing and assembly deviations between the core frames, there will always be defects such as excessive gaps between the cores and uneven inner surfaces of the core windows; binding the core columns cannot completely fix the core frames; after the coil assembly is completed, due to the amorphous core The characteristic of being unable to bear force requires turning the body over to hang it on the coil so that it only bears its own gravity, which greatly increases the difficulty of the transformer's process; and the three-phase three-column amorphous alloy core structure has an open frame. The length of the iron yoke is too long, which makes it difficult to handle the iron yoke after opening; the amorphous alloy core frame is relatively loose, which leads to the stress of the core during product installation and transportation, which affects the performance of the product
