Transformer insulation case with dampproof function

Abstract

The invention discloses a transformer insulation case with a dampproof function. The transformer insulation case comprises a base plate. A rubber case is fixedly connected to the top of the base plate; the internal surface of the rubber case is fixedly connected with a first case body; a circular pipe is fixedly connected to the internal surface of the first case body via a supporting rack; and athrough hole is formed in the surface of the circular pipe. The invention relates to the technical field of transformer damproof insulation cases. With the rubber case fixedly connected to the top ofthe base plate, air humidity of the interior of the insulation case can be maintained all the time and the air is at a dry state all the way; damage of the internal transformer due to excessive high temperature can be prevented, so certain temperature is remained for the interior of the insulation case; frequent exchange of the transformers can be avoided; the transformer is only exchanged when the service life is expired; therefore, use cost of the transformer can be reduced; and a problem of internal air humidity maintenance failure of transformer insulation cases in the prior art can be overcome.

Description

technical field [0001] The invention relates to the technical field of a transformer moisture-proof insulation box, in particular to a transformer insulation box with a moisture-proof function. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). In electrical equipment and wireless circuits, it is often used for lifting voltage, matching impedance, safety isolation, etc. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. In electric...
