Abstract
The invention discloses an iron core of an amorphous alloy transformer and a manufacture method thereof. The iron core of the amorphous alloy transformer comprises a wound core formed by coiling iron-based amorphous alloy belt materials. Mixed resin packages the wound core, so that a lower yoke of the wound core can not be opened. The mixed resin forms a resin layer on the periphery of the wound core. The resin layer is fixedly connected with a grounding sheet which is electrically connected to the wound core. The amorphous alloy transformer can be directly used for coiling wound core coils of oil-immersed transformers and dry type transformers. Due to the fact that the amorphous alloy transformer formed by resin packaging the wound core is an effective whole body, the resin-packaged amorphous alloy transformer is low in noise, the production efficiency of products is effectively improved, and the defects that the amorphous alloy iron core can deform and be broken easily are overcome. Moreover, stacking the lower yokes of iron cores, due to the fact that products are placed in a sleeved mode, can not increase consumption of the amorphous alloy transformer iron cores. The invention further discloses a manufacture method of the amorphous alloy transformer.
