A support cushion block for a three-dimensional coiled iron core and a transformer

Abstract

A support cushion block for a three-dimensional coiled iron core and a transformer are provided, the three-dimensional coiled iron core comprises three single-frame iron cores which are spliced at anincluded angle of 60 degrees, a support cushion block comprises a cushion block body, wherein the cushion block body is arranged at the bottom end of the three-dimensional coiled iron core and is located between adjacent single-frame iron cores, and has a bearing surface bearing the single-frame iron cores and a support surface matched with a support structure, and the bearing surface provides a support force opposite to gravity to the single-frame iron cores. According to such a design, the support cushion block is arranged, so that the single-frame iron core s are not easy to deform in the use process, thereby ensuring the performance of the three-dimensional coiled iron core and the transformer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a support block for a three-dimensional wound iron core and a transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. The three-dimensional wound core transformer has the advantages of three-phase magnetic circuit balance, low loss and low noise, so it is welcomed and favored by more and more users. [0003] The three-dimensional wound core is the core component of the three-dimensional wound core transformer. The three-dimensional wound iron core is arranged vertically. Because it is tall and heavy, it is easy to deform under the action of gravity, which will affect the no-load loss and then affect the performance of the transformer. Contents of the invention [0004] Therefore, the technical problem to be solved by th...
