Abstract

The invention discloses an automatic radiating transformer which comprises a coil rack, a magnetic core, an insulating pad and an air blower, wherein a coil is wound on the coil rack, the magnetic core is arranged in a center through hole of the coil rack, the insulating pad is used for wrapping the magnetic core and is fixed in the through hole of the coil rack, and the air blower is arranged under the insulating pad. The insulating pad is composed of an insulating pad body, a breathable component which is arranged on the insulating pad body and is communicated with the air blower, and a clamping piece which is arranged on the insulating pad body and is clamped on the coil rack. The automatic radiating transformer can automatically radiate the heat from the magnetic core, the aging process of the insulating pad slows down, and service life of the transformer is prolonged.

Description

technical field [0001] An electrical device, especially 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 first air-venting 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] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a device that can automatically dissipate the heat from the magnetic core, slow down the aging of the insulating pad, and increase the service life of the transformer. ...
