Abstract
The utility model provides a high-performance dry transformer, which has the structure that the utility model is composed of a high-voltage winding, a low-voltage winding, a wide-range silane alkali-free glass fibre insulation tape and an epoxy resin casting material. The wide-range silane alkali-free glass fibre insulation tape is clamped between the layers of the electromagnetic wires of the high-voltage winding and the low-voltage winding. The epoxy resin casting material causes the electromagnetic wires of the high voltage winding and the low-voltage winding and the wide-range silane alkali-free glass fibre insulation tape to be solidified together. The high-performance dry transformer has the characteristics of reasonable design, simple structure, easy manufacturing, good performance of the flame retardancy and high temperature resistance, good ageing resistance and insulating property, etc.
Description
The utility model relates to a kind of power transmission and transforming equipment, specifically a kind of high-performance dry-type transformer.
The in use existing deficiency of the dry-type transformer of prior art is high temperature resistant, ageing resistace difference etc.
The purpose of this utility model provides that a kind of cost is low, high temperature resistant, anti-aging, the high-performance dry-type transformer of high-insulativity.
The purpose of this utility model realizes in the following manner, at coiling dry-type transformer height, the electromagnetic wire outer surface of low-voltage coil with silane alkali-free glass fiber insulating tape in a narrow margin twine make high temperature resistant, the insulating barrier that fire resistance is good, turn to the height of dry-type transformer again with the electromagnetic wire of this structure, low coil, at dry-type transformer line height, the layer of low-voltage coil electromagnetic wire with layer between twine with wide cut silane alkali-free glass fiber insulating tape and to make the layer insulation separator, use the epoxy casting material electromagnetic wire and wide cut silane alkali-free glass fiber insulating tape cast cured explosive to be become the height of dry-type transformer at last, low-voltage coil.
Accompanying drawing is the structural representation of high-performance dry-type transformer.
Explain below with reference to Figure of description high-performance dry-type transformer of the present utility model being done.
High-performance dry-type transformer of the present utility model, its structure is to be made of high pressure winding 1, low pressure winding 2, wide cut silane alkali-free glass fiber insulating tape 3 and poured with epoxy resin material 4, wide cut silane alkali-free glass fiber insulating tape 3 is clipped between the layer and layer of high pressure winding 1, low pressure winding 2 electromagnetic wires, and poured with epoxy resin material 4 is solidified togather the electromagnetic wire and the wide cut silane alkali-free glass fiber insulating tape 3 of high pressure winding 1, low pressure winding 2.
High pressure winding 1 and low pressure winding 2 are to be formed by electromagnetic wire 5 coilings, and the outer surface of electromagnetic wire 5 adopts in a narrow margin silane alkali-free glass fiber insulating tape 7 to twine and is made into insulating barrier 6.
Embodiment:
Its processing and fabricating of high-performance dry-type transformer of the present utility model is very simple and convenient, and processing and fabricating both can shown in the by specification accompanying drawing.Wide cut and in a narrow margin silane alkali-free glass fiber insulating tape be that the glass fibre that adopts organo-silicon coupling agent to handle is formed by weaving, the interlayer that is arranged on electromagnetic wire outer surface and electromagnetic wire with this insulating tape can improve the firmness that combines between electromagnetic wire and the pours, and the ageing resistace of dielectric coefficient, fire resistance and transformer coil between electromagnetic wire is increased substantially, can prolong the useful life of transformer significantly, improve the global design level of dry-type transformer.
High-performance dry-type transformer of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, flame-resistant high-temperature-resistant performance, ageing resistace and good insulation preformance, thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
