Extinguishment transformer

Abstract

The invention discloses an extinguishment transformer. The extinguishment transformer comprises a coil frame and a magnetic core, wherein the coil frame is wound with a coil, and the magnetic core is placed in a central through hole of the coil frame. The extinguishment transformer further comprises a fireproof transformer casing, ventilation openings arranged on two sides of the fireproof transformer casing, rotatable sealing modules arranged beside the ventilation openings and sealing the ventilation openings, a temperature sensor arranged in the fireproof transformer casing and an air suction part placed on the fireproof transformer casing. When the coil or the magnetic core is overheated and fires caused by coil combustion are caused, the transformer can be sensed and automatically sealed, oxygen in the transformer is sucked away, the effect of extinguishment is achieved, and the extinguishment transformer is good in effect and low in cost.

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 promote 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. Cause local fire, safety accident takes place, prior art has not solved such problem yet. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a method that can sense and automatically seal the transformer when the coil or the...
