Abstract
The utility model relates to a honeycomb epoxy resin insulator of a dry type transformer, belongs to the technical field of the dry type transformers, aims at solving the problems of poor heat dissipation performance and high production cost of the insulator between a high-voltage coil and a low-voltage coil of the existing dry type transformer and provides the honeycomb epoxy resin insulator of the dry type transformer. The honeycomb epoxy resin insulator of the dry type transformer is arranged between the high-voltage coil and the low-voltage coil of the dry type transformer, the honeycomb epoxy resin insulator has a pipy structure and a through heat dissipation gas passage is arranged along the axial direction of the honeycomb epoxy resin insulator. When the honeycomb insulator is manufactured, the high-voltage coil and the low-voltage coil can be arranged into a mold together for performing pouring, gelatination and curing together and a transformation working winding of the transformer is finally formed, thereby doubling the production efficiency of pouring equipment, improving the reliability of the transformer and achieving the purposes of saving materials and reducing loss.
Description
Technical field
The utility model belongs to the Dry-Transformer Technology field, particularly a kind of high-tension coil of dry-type transformer and the seal between the low-voltage coil.
Background technology
Existing Transformer Winding is the dry-type transformer most important component, and it is to finish the electromagnetic coupled effect electrical energy transfer is given in the secondary electrical network; It also is the position of bearing voltage, rush of current simultaneously, requires to have physical properties such as certain electrical strength, high-temperature capability, mechanical strength.
Former epoxy resin dry type transformer leaves bigger air gap usually between the high and low pressure coil, solving the heat radiation and the Insulation Problems of high and low pressure coil, so its structure all is the separately cast separately of high and low pressure coil, and then assembling; Or the centre adds an insulation barrier; Or employing solid insulation structure etc.
These structures are cost to reduce certain insulation property and heat dispersion, and because of air and insulating material all have individual bulk effect, both more little insulation volume compressive resistance is high more, and another drawback is to hide more heat-delivery surface, can influence heat dispersion.This has just brought insulation distance to strengthen and has increased radiating surface, and the time that a large amount of casting molds and cast, gel, curing, assembling produce and the loss of energy produce a large amount of production costs.In order to reduce production costs, improved the reliability of transformer, popularize dry-type transformer and use, adopt the honeycomb fashion insulation system of my company, can address the above problem.。
The utility model content
For the heat dispersion of the insulator between the high and low pressure coil that solves existing dry-type transformer bad, the problem that production cost is high, the utility model provides a kind of dry-type transformer cellular epoxyresin insulator, its embodiment is as follows:
The cellular epoxyresin insulator of dry-type transformer is arranged between the high-tension coil and low-voltage coil of dry-type transformer, and this cellular epoxyresin insulator is provided with the heat radiation air flue of perforation in tubular construction vertically.
This cellular insulator during fabrication, the mould of the high and low pressure coil can being packed into together, together cast, gel, curing become transformer power transformation work winding at last.
This cellular insulator is divided into a plurality of air gaps to the air layer between the high and low pressure coil, has strengthened dielectric strength, has increased radiating surface, and adopts the heat radiation of many eddy current flow-disturbing, thereby has improved radiating efficiency; Improved mechanical strength between the high and low pressure coil, production technology is simple, rational in infrastructure, can reduce by 1/2nd casting mold, reduce by 1/2nd cast, gel, curing time, improve one times of casting equipment production efficiency, improved the reliability of transformer, reach the purpose of saving material and reducing the wastage.
As preferred version of the present utility model, described heat radiation air flue has three layers from inside to outside, evenly distributes in the form of a ring with one deck heat transmission gas road.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the cutaway view of the cellular epoxyresin insulator of dry-type transformer.
