[0002] The transformer core is the main magnetic circuit part of the transformer, which is usually made of hot-rolled or cold-rolled silicon steel sheets with a high silicon content and insulating paint on the surface.
[0003] In the related art, when the transformer core is produced, the clamp is generally placed on the tooling first, and then the silicon steel laminations are stacked on the clamp. When the silicon steel laminations are stacked, an armature block is placed on one side to locate the position of the silicon steel laminations. When the silicon steel laminations are stacked to a certain height, they are stacked together through the armature block.

[0024] like Figure 1-Figure 2 As shown, the transformer core with positioning function provided in the embodiment of the present application includes a first silicon steel sheet 100, a second silicon steel sheet 400 and a plurality of stacked sheets 700, wherein the first silicon steel sheet 100 and the second silicon steel sheet 400 are both part of the transformer core. In the present embodiment, the first silicon steel sheet 100, the second silicon steel sheet 400 and the plurality of stacked sheets 700 are all silicon steel laminates.
[0025] The upper surface of the first silicon steel sheet 100 is vertically provided with a plurality of first baffles 200, which are distributed at two wide edges and one long edge of the first silicon steel sheet 100 to form a U-shaped structure. In addition, the first baffles 200 at the wide edge are provided with T-shaped grooves 300.

Multiple stacking sheets 700 are stacked in the receiving slot, and together with the first silicon steel sheet 100, the first baffle 200, the second silicon steel sheet 400 and the second baffle 500, they form the iron core of the transformer. The outer diameter of each stacking sheet 700 is adapted to the inner diameter of the receiving slot.
