Abstract

The utility model discloses an epoxy resin pouring dry transformer which is good in radiating performance and is characterized in that a radiating layer is arranged between a low-voltage winding and a high-voltage winding. The radiating layer is formed by a plurality of vent pipes arranged axially and radiating materials. The vent pipes are arranged closely to form a ring, and the radiating materials are arranged between adjacent vent pipes. By arranging the radiating layer formed by the plurality of vent pipes arranged axially and the radiating materials between the low-voltage winding and the high-voltage winding, the radiating performance of the dry transformer is effectively improved, and the service life is prolonged.

Description

Cast Resin Dry-Type Transformer
Technical field
The utility model relates to a kind of transformer, and more particularly, it relates to a kind of Cast Resin Dry-Type Transformer.
Background technology
Transformer Winding is the most important part of dry-type transformer, and it has been that electromagnetic coupled effect passes to energy in secondary electrical network; It is also the position of bearing voltage, rush of current simultaneously, requires to have the physical properties such as certain electrical strength, high-temperature capability, mechanical strength.
Its heat dispersion of existing epoxy resin dry type transformer is not enough, has a strong impact on the useful life of transformer.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of Cast Resin Dry-Type Transformer with stronger heat dispersion.
For achieving the above object, the utility model provides following technical scheme: a kind of Cast Resin Dry-Type Transformer, comprise the high pressure winding, low pressure winding, the iron core that are located at successively in epoxy resins insulation layer, between described low pressure winding and high pressure winding, there is heat dissipating layer, described heat dissipating layer consists of the some breather pipes and the heat sink material that axially arrange, described breather pipe annular close-packed arrays, described heat sink material is located between adjacent breather pipe.
Between described adjacent breather pipe, be provided with through hole.
Described breather pipe is made by insulating material.
By adopting technique scheme, between the low pressure winding of this Cast Resin Dry-Type Transformer and high pressure winding, be provided with heat dissipating layer, heat dissipating layer consists of the heat sink material between the breather pipe axially arranging and adjacent breather pipe, the heat dispersion that it effectively raises this dry-type transformer, has extended useful life.
Accompanying drawing explanation
Fig. 1 is the structure cutaway view of the utility model Cast Resin Dry-Type Transformer embodiment.
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
Reference numeral: 1, epoxy resins insulation layer; 2, high pressure winding; 3, heat dissipating layer; 31, breather pipe; 32, through hole; 4, low pressure winding; 5, iron core.
Embodiment
See figures.1.and.2 the utility model Cast Resin Dry-Type Transformer embodiment is described further.
A kind of Cast Resin Dry-Type Transformer, comprise the high pressure winding 2, low pressure winding 4, the iron core 5 that are located at successively in epoxy resins insulation layer 1, between described low pressure winding 4 and high pressure winding 2, there is heat dissipating layer 3, described heat dissipating layer 3 consists of the some breather pipes 31 and the heat sink material that axially arrange, the described annular close-packed arrays of breather pipe 31, described heat sink material is located between adjacent breather pipe 31.Between the low pressure winding 4 of this Cast Resin Dry-Type Transformer and high pressure winding 2, be provided with heat dissipating layer 3, heat dissipating layer 3 consists of the heat sink material between the breather pipe 31 axially arranging and adjacent breather pipe 31, the heat dispersion that it effectively raises this dry-type transformer, has extended useful life.
Between described adjacent breather pipe 31, be provided with through hole 32.This through hole 32 can make air-flow intercommunication between breather pipe 31, is more conducive to heat radiation; And when assembling, can utilize this through hole 32 that breather pipe 31 is bundled in outside low pressure winding 4, be conducive to the operation of arranging of breather pipe 31.
Described breather pipe 31 is made by insulating material.Can between high pressure winding 2 and low pressure winding 4, play insulation protection effect.
