Problems solved by technology
[0002] For transformers, the three-dimensional wound core is an indispensable part. Most of the existing three-dimensional wound cores are composed of three identical single-frame cores wound continuously with silicon steel sheets, although they can meet the basic requirements of transformers. , but the space utilization rate of the existing three-dimensional wound core is low. When it is necessary to reduce the no-load loss, the only way to increase the cross-sectional area of the single frame of the core is to increase the total height of the three-dimensional wound core and increase the production cost.

The invention discloses a novel three-dimensional wound core, which comprises three identical core frames. Each core frame comprises a bottom plate and side plates integrally formed on the two sides of the bottom plate. The angles between the surface of the bottom plate and the surfaces of the side plates are the same, and the bottom plate and the side plates constitute a concave plane. The side plates of the three core frames are joined and spliced in pairs to form a core. Three identical single core frames are arranged in the three concave planes of the core, and thus, a three-dimensional wound core is formed. Each single core frame is internally provided with a concave window with the windowing size gradually decreasing towards the center. The windowing direction of each concave windowis consistent with the opening direction of the corresponding concave plane. By adding the core in the middle of the single frames, the overall cross-sectional area of the wound core is increased, andthe height of the wound core can be well controlled.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to a novel three-dimensional wound iron core. Background technique [0002] For transformers, the three-dimensional wound core is an indispensable part. Most of the existing three-dimensional wound cores are composed of three identical single-frame cores wound continuously with silicon steel sheets, although they can meet the basic requirements of transformers. , but the space utilization rate of the existing three-dimensional wound core is low. When it is necessary to reduce the no-load loss, the cross-sectional area of the single frame of the core can only be increased, which will inevitably increase the total height of the three-dimensional wound core and increase the production cost. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems in the prior art, and provide a new three-dimensional wound core, whic...
