Transformer

Abstract

The invention discloses a transformer, which comprises a coil former, a magnetic core and a replaceable insulation mat assembly, wherein the magnetic core is arranged in the center through hole of the coil former; the replaceable insulation mat assembly is arranged between the magnetic core and the coiler former; the coiler former is provided with a placement groove used for containing a coil; the insulation mat assembly comprises two opposite insulation mats; each insulation mat is provided with an insulation mat body and a handle, wherein the insulation mat body is used for isolating the magnetic core from the coil former; the handle is arranged on the end part of the insulation mat body and is clamped on the inner side of the coil former; the handle extends to the outer side of the coil former; the handle is provided with a groove where a hand is put; and the magnetic core comprises a first magnetic core and a second magnetic core, wherein the first magnetic core and the second magnetic core are independently combined by an alloy material layer and a ferrite layer, the shape of the alloy material layer is not completely same with the shape of the ferrite layer, the integral magnetic core is formed after the alloy material layer and the ferrite layer are combined, and the main body surfaces of the first magnetic core and the second magnetic core respectively form a first magnetic pillar and a second magnetic pillar, wherein the first magnetic pillar and the second magnetic pillar externally extend. The transformer has the advantages of being convenient in use, good in cooling effect and high in stability.

Description

technical field [0001] The invention relates to a transformer, in particular to a transformer. Background technique [0002] A transformer according to the prior art mainly has a form in which a primary coil and a secondary coil are sequentially wound on a single bobbin, and a core is coupled to the bobbin through a through hole of the bobbin. In order to avoid leakage or other accidents, an insulating pad is usually provided between the magnetic core and the coil frame, but the magnetic core will generate heat during operation, which will cause the aging of the insulating pad and reduce the service life of the transformer. The prior art has not yet solved this problem. The problem. Contents of the invention [0003] The object of the present invention is to provide a transformer that is easy to use, has good heat dissipation effect and high stability, so as to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above objec...
