Abstract

The invention relates to a combined transformer, and belongs to the field of transformers. A framework is arranged, and a winding groove is machined in an outer side wall of the framework. A frameworkhole is arranged in the middle of the framework; annular limiting holes parallel to the winding groove are further machined in the framework; and at least two annular copper sheets are inserted intothe annular limiting holes, breaking seams are machined in the annular copper sheets, an annular insulating spacer is inserted between every two adjacent annular copper sheets, the two adjacent annular copper sheets are connected in series, and two cylindrical magnetic cores are inserted into the framework hole and penetrate through copper sheet holes in the middle of the copper sheets and an insulating sheet hole in the middle of the insulating spacer. A copper wire is replaced with the copper sheet, a risk of wire breakage is eradicated, a technological process of winding is simplified, quality stability of the transformer is guaranteed, and cost of an enterprise is correspondingly reduced. Limiting grooves of the framework and the copper sheets which are used as limiting plates are cooperated to achieve assembling, disassembling and integration are more convenient, and conversion between one output end and two output ends of the transformer can be achieved.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a combined transformer. Background technique [0002] As we all know, with the development of electronic products, high-power transformers are more and more urgently needed, which requires transformer products to adopt high-power designs as much as possible. PQ shape transformers are more and more widely used because of their advantages of large output power. However, when the PQ shape transformer is processed and manufactured according to the traditional production process, it is easy to appear: (1) the copper wire is broken. The whole power board is paralyzed. (2) The winding process is cumbersome. The winding process of the traditional process involves various processes such as winding, hanging, knotting, and tinning, and there are many hidden dangers. (3) After the traditional transformer is wound, it is inconvenient to disassemble, repair and reintegrate. (4) After the tradit...
