Abstract
The invention discloses a dry type transformer. According to the technical scheme, the dry type transformer comprises a bottom frame, a draught fan, an outer protective cover and an iron core assembly, wherein the draught fan is located on a draught fan support, the draught fan support is arranged on the bottom frame, a lower cushion block is arranged between the draught fan support and the bottom frame, the iron core assembly is located on the bottom frame, and the outer protective cover is arranged on the periphery of the iron core assembly. The iron core assembly comprises a high-voltage coil, a low-voltage coil and a fixing bar, wherein the low-voltage coil is connected with a temperature control instrument which is connected with the draught fan, the high-voltage coil is connected with a high-voltage insulator, and the low-voltage coil is connected with a low-voltage insulator. The dry type transformer has the advantages that a single transformer is developed into the multifunctional combined type transformer with the air cooling function and the outer shell protection function and with the temperature control instrument, a temperature sensor and the like, and therefore the dry type transformer is safe in running, free of pollution and long in service life, and the use range of the dry type transformer is enlarged.
Description
Technical field
The present invention relates to transformer technology field, relate in particular to a kind of dry-type transformer.
Background technology
It is cooling that dry-type transformer relies on cross-ventilation to carry out, and is generally used for localized lighting, electronic circuit.The isallobaric device of plant equipment, in electric power system, general steam turbine transformer, boiler transformer, ash disposal transformer, dust removing transformer, desulfurization transformer etc. are all dry-type transformers, and no-load voltage ratio is 6000V/400V and 10KV/400V, for the load with rated voltage 380V.Briefly dry-type transformer just refers to that iron core and winding are not immersed in the transformer in insulating oil.
