Problems solved by technology

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 cause the coil to age. Causing local fires and safety accidents, such problems have not been solved in the prior art

Embodiment Construction

[0016] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0017] A fire-proof transformer, including: a coil frame 1 for winding coils, a magnetic core placed in the central through hole of the coil frame 1, a fire-resistant transformer shell 5, vents 8 on both sides of the fire-resistant transformer shell 5, and rotatable and closed vents beside the vent 8 Closure assembly for vent 8, temperature sensor 6 inside refractory transformer housing 5.

[0018] The closure assembly consists of: a rotating part fixed on the refractory transformer casing 5, preferably an electric rotating shaft 4; a closing cover 2 connected to the rotating part, a sealing layer 3 covering the above closing cover 2 and contacting the vent 8 Preferably, the sealing layer 3 is a rubber layer; the material used for the fire-resistant transformer shell 5 is a thermosetting resin-impregnated paper high-voltage laminate.

Abstract

The invention discloses a fire-resistant transformer, which comprises: a coil frame wound with a coil, a magnetic core placed in the central through hole of the coil frame, a fire-resistant transformer shell, vents arranged on both sides of the fire-resistant transformer shell, and a A closure assembly that can rotate and close the vent, and a temperature sensor located in the shell of the fire-resistant transformer. The invention provides a fire-resistant sealing cover that can close the coil, which can provide a sealed space for the coil in case of fire, and the coil cannot maintain combustion due to no oxygen supply, so as to realize fire extinguishing and avoid safety accidents.

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 object of the present invention is to provide a refractory sealing layer made of non-combustible refractory material, which can pr...
