Problems solved by technology

As we all know, during the use of transformers, due to electromagnetic induction, high temperature occurs inside the transformer core, which makes it difficult to dissipate heat. Although the exhaust fan is used to dissipate heat in the prior art, the internal heat held between the transformer cores is difficult to dissipate in time. Excluded, so it needs to be developed and improved to improve the efficiency of heat dissipation

Abstract

The invention discloses a transformer magnetic core and a transformer. The transformer comprises a transformer shell, wherein an oil conservator and a gas relay are installed at the upper end of the transformer shell, and a signal thermometer is fixedly installed on the side wall of the transformer shell; an inner cavity of the transformer shell is provided with a heat dissipation type magnetic core for performing voltage transformation conveniently, and primary and secondary coils wound on the heat dissipation type magnetic core; and the front end of the primary coil is electrically connectedwith a high-voltage bushing wiring terminal, and the secondary coil end is electrically connected with a low-voltage bushing wiring terminal. According to the improved transformer, internal heat dissipation, air suction and heat dissipation and external diffusion and heat conduction are integrated, so that the heat dissipation effect is greatly improved, and the service life of the transformer isprolonged.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer magnetic core and a transformer. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.). Circuit symbols often use T as the ...
