The invention discloses a transformer with an automatic cooling function. The transformer comprises a coil frame, a magnetic core, a spiral insulating pad, a spiral ventilation passage, a dry ice manufacturing machine and a clamping piece, wherein the coil frame is wound with a coil, the magnetic core is arranged in a through hole in the center of the coil frame, the spiral insulating pad wraps the magnetic core and is fixed in the through hole of the coil frame, the spiral ventilation passage is formed among the spiral insulating pad, the magnetic core and the coil frame, the dry ice manufacturing machine is connected to the ventilation passage, and the clamping piece is arranged on an insulating pad body and is clamped on the coil frame. Dry ice can be automatically injected into the transformer for uniformly and completely bringing out heat generated by the magnetic core and heat generated by the coil, so that the ageing of the coil is efficiently relieved, and accordingly the 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 through hole of the bobbin. In order to avoid leakage or other accidents, an insulating pad is usually installed 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 the coil will also generate heat, and the heat will accumulate, which will promote the aging of the coil and reduce the The service life of transformer, prior art has not solved such problem yet. 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 method that can automatically and efficiently reduce the heat emitted by the magneti...
