Embodiment
[0030] like Figure 1 to Figure 5 As shown, a three-column amorphous iron core with tie plates includes an amorphous core body 1 , tie plates 2 , grid layout plates 7 and composite templates 8 . Wherein, the amorphous iron core body 1 includes an outer frame iron core 2 and two inner frame iron cores 3, and the two inner frame iron cores 3 are arranged side by side in the outer frame iron core 1, and the outer frame iron core 2 and the inner frame iron core 3 are One-piece structure, all of which are formed by lapping multiple stacks of amorphous alloy strips, forming a circular rectangle, and the lap joints 11 face the same side. In this embodiment, there are two amorphous core bodies 1, which are divided into upper and lower layers. put. The pull plates 2 are respectively located on the bottom surface of the lower amorphous core body 1 and the upper surface of the upper amorphous core body 1, which include a horizontal bottom plate 5 and three vertical plates 6, and the thr...

The invention discloses a three-column amorphous iron core with a pulling plate. The three-column amorphous iron core with the pulling plate comprises an amorphous iron core body and the pulling plate, wherein the amorphous iron core body comprises an outer frame iron core and two inner frame iron cores which are of an integral structure. The three-column amorphous iron core with the pulling plate also comprises a grid cloth plate and a composite membrane plate which are arranged between the amorphous iron core body and the pulling plate, wherein the grid cloth plate and the composite membrane plate keep away from a lap joint port of the amorphous iron core body, and the amorphous iron core body, the grid cloth plate, the composite membrane plate and the pulling plate are integrally cured through epoxy resin. The invention also discloses a manufacturing method of the three-column amorphous iron core with the pulling plate. According to the three-column amorphous iron core with the pulling plate, disclosed by the invention, the outer frame iron core and the inner frame iron cores are integrally formed before annealing, and then the fragment amount in a follow-up assembling process is reduced, so that the no-load loss and noise of a transformer are effectively reduced. By additionally arranging the grid cloth plate and the composite membrane plate, the insulation resistance value of the transformer can be effectively increased, and the stability of the transformer can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of manufacturing an amorphous alloy dry-type transformer core, in particular to a three-column amorphous core with a pull plate and a manufacturing method thereof. Background technique [0002] Amorphous alloy distribution transformer is a kind of energy-saving power distribution equipment using new materials, new structure, and new technology. Its core material is an amorphous alloy, which has outstanding low no-load loss characteristics compared with traditional silicon steel cores. . The existing three-column amorphous alloy dry-type transformer core consists of an outer frame iron core and two identical inner frame iron cores, wherein the two inner frame iron cores are arranged side by side in the outer frame iron core, and the outer frame iron core and the two inner frame iron cores The manufacturing material of the core is formed by lapping several layers of amorphous alloy strips, and the overlapping...
