Problems solved by technology

However, in the existing inductance transformer, an insulating sheet is provided between the strip-shaped silicon steel sheet and the mountain-shaped silicon steel sheet, which will increase the air gap of the transformer, resulting in larger external magnetic flux leakage, which is likely to cause interference to other circuits; in addition, Due to the existence of the insulating sheet, the transformer will vibrate during operation, causing excessive noise and unstable electrical parameters.

Abstract

The invention aims to provide an inductance transformer which is small in magnetic leakage, small in noise and stable in electrical parameter and a fabrication method thereof. The transformer comprises a winding (1) and a framework and also comprises an elongate silicon steel sheet group (2) and a mountain-shaped silicon steel sheet group (3), wherein the winding sleeves an intermediate strip group of the mountain-shaped silicon steel sheet group, the elongate silicon steel sheet group (2) is arranged at one side, wherein an opening is formed, of the mountain-shaped silicon steel sheet group (3), the framework encircles peripheries of the winding (1), the elongate silicon steel sheet group (2) and the mountain-shaped silicon steel sheet group (3) to form a transformer main body, a transformer protection box (4) is further arranged at the periphery of the framework, the transformer main body is arranged in the transformer protection box (4), and other gaps in the transformer protectionbox (4) are filled with epoxy resin. The fabrication method of the transformer comprises the following steps of arranging the transformer main body; casting epoxy resin glue; and curing the epoxy resin. The fabrication method can be applied to the field of transformers.

Description

technical field [0001] The invention relates to the field of transformers, in particular to an inductance transformer and a preparation method thereof. Background technique [0002] The silicon steel sheet inductance transformer generally includes a strip silicon steel sheet group and a mountain-shaped silicon steel sheet group, and the whole transformer is obtained after stacking and alignment. However, in the existing inductance transformer, an insulating sheet is provided between the strip-shaped silicon steel sheet and the mountain-shaped silicon steel sheet, which will increase the air gap of the transformer, resulting in larger external magnetic flux leakage, which is likely to cause interference to other circuits; in addition, Due to the existence of the insulating sheet, the transformer will vibrate during operation, causing excessive noise and unstable electrical parameters. If a transformer can be designed that can reduce the air gap and does not require insulatin...
