Problems solved by technology

[0002] Due to the unstable performance of large-width amorphous alloy strips, the specifications of amorphous alloy strips on the market are only 142mm, 172mm, and 213mm. The capacity of the transformer is limited due to the limitation of the width of the amorphous strip. The existing amorphous alloy three-dimensional wound iron core is only suitable for oil-immersed amorphous alloy distribution transformers and small-capacity amorphous alloy dry-type transformers, and cannot be used for large-capacity transformers, which limits the design capacity of transformers

Abstract

The invention discloses a three-dimensional reel iron core of an amorphous alloy transformer. A core column in the iron core of the transformer is composed of a plurality of amorphous alloy bands, the core column with any diameter size can be obtained, the phenomenon that the diameter of the core column is limited by the bandwidth size of bands in the past is avoided, the design capacity of the transformer is increased, and the finished product performance of the iron core of the transformer is improved. The three-dimensional reel iron core can be widely applied to large-capacity amorphous alloy distribution transformers, large-capacity amorphous alloy dry type transformers and amorphous alloy main transformers.

Description

technical field [0001] The invention relates to a three-dimensional wound iron core of an amorphous alloy transformer. Background technique [0002] Due to the unstable performance of large-width amorphous alloy strips, the specifications of amorphous alloy strips on the market are only 142mm, 172mm, and 213mm. The capacity of the transformer is limited due to the limitation of the width of the amorphous strip. The existing amorphous alloy three-dimensional wound iron core is only suitable for oil-immersed amorphous alloy distribution transformers and small-capacity amorphous alloy dry-type transformers, and cannot be used for large-capacity transformers, which limits the design capacity of transformers. Contents of the invention [0003] The invention provides a three-dimensional wound iron core of an amorphous alloy transformer. A plurality of amorphous alloy strips are used to form a core column in the transformer iron core, and a core column of any size can be obtained...
