Abstract
The utility model relates to a composite silane alkali-free glass fibre belt, which provides a novel insulating material for manufacturing a dry transformer and has the advantages of high performance, heat resistance and high grade in insulation. The utility model has the structure that the low twist plied yarn treated by adopting the composite silane is used as a warp and a woof to be woven into a tape shape by a textile machine. The thickness and the width can be changed according to the dry transformer and the requirement of a high-low voltage winding. Compared with the prior art, the composite silane non-alkali glass fibre belt has the characteristics of low content of the alkali metal oxide, good immersion with the resin, good performance of the heat and electric resistance, strong aging resistance and adaptability, etc., and has the advantage of good compatibility.
Description
The utility model relates to the insulating materials field, specifically makes self cooling heat-resisting, a kind of novel high-grade insulating materials---compound silane alkali-free glass fibre band that high energy low consumption H level dry-type transformer is invented for exploitation.
Over past ten years, dry-type transformer has swift and violent development because of but it has characteristics such as the environmental protection of benefiting, nonflammable, safe ready, non-maintaining and near point power supply in China, having experienced with institute Weihe " band filler heavy insulation poured with epoxy resin dry-type transformer " is the guiding phase, be converted to now that " the thin insulating poured with epoxy resin dry type transformation that glass fibre strengthens presses the high speed of outshining othersOne branch of the tree is particularly thriving to grow up, and is just progressing into the maturity period that a hundred flowers blossom.The characteristics in maturity period are that technical matters becomes more diverse, and the Application Areas of product enlarges day by day.As one of main raw material(s) of dry-type transformer, insulating materials performance quality, how economy has become the important step of expansion, in market competition very fierce today, each producer is devoted to seek insulating properties and the heat-resisting quantity that super quality and competitive price, insulating materials that scientific and technological level is high are improved transformer one after another, develops high-performance, power transmission and transforming equipment cheaply.
The purpose of this utility model provides a kind of insulating substrate that is applicable to that resin filled type and wound form dry-type transformer coil are made, and is easy to the compound silane alkali-free glass fiber band of resin penetration.
The purpose of this utility model realizes in the following manner, select the active alkali-free glass fiber single thread that soaks into compound silane coupling agent drawing process for producing of macromolecule for use, piece together the synthetic multiply low twist yarn of operation through moving back, be used for graticule, adopt textile machine to be woven into compound silane glass fiber tape by the design technology regulation, its structure is rare density plain weave or twill, be applicable to that high-grade dry-type transformer coil makes layer insulation and isolate, improve transformer operating temperature and high temperature insulation level after the impregnated with resin, the mechanical strength of coil and the ageing resistance of insulation have been strengthened, but and the NPMEX of import substitution, reduced manufacturing cost, improved the transformer resistance.Surround the electromagnetic wire that the high-low pressure winding that can be made into dry-type transformer on the bare lead is used with this band, the performance technologies index of this electromagnetic wire surpasses alkali-free does not have the magnet wire property technical indicator that cured glass fibre belt packs work.The electromagnetic wire that adopts compound silane alkali-free glass fiber band to hold turns to dry-type transformer coil very easily in resin impregnated, thereby improve the rigidity of coil, the short circuit accident that the insulation ag(e)ing that has reduced the shelf depreciation of coil and caused because of operating temperature is overheated is made has improved service life.
Accompanying drawing 1 is compound silane alkali-free glass fiber band graticule braided structure schematic diagram;
Accompanying drawing 2 does not have the section structure schematic diagram of crying out glass fibre belt to adhere to compound silane coupling agent for compound silane.
Explain below with reference to Figure of description compound silane alkali-free glass fiber band of the present utility model being done.
Compound silane alkali-free glass fiber band of the present utility model, its structure is to be made of warp 1 and parallel 2, and warp 1 and parallel 2 are to be coated with compound silane coupling agent 3,4 low by the surface to harvest glass fibre 5 stranded forming, and warp 1 is through in the middle of the parallel 2.
Embodiment:
Compound its processing and fabricating of silane alkali-free glass fiber band of the present utility model is very simple and convenient, and processing shown in the by specification accompanying drawing is manufactured and got final product.Silane coupler is commercially available organosilicon product, and glass fibre is general glass fibre, and compound silane alkali-free glass fiber band is to use the fiberglass yarn of band silicone couplet composite coating to be formed by weaving by weaving loom.
Composite silance alkali-free glass fibre belt of the present utility model be compared with existing technology have following excellent The point;
1, the most oxide content of alkali gold is less than 0.4;
2, the molecular activity sizing agent is better than the internal performance of enhancing property infiltration wire drawing;
3, use composite coupler to handle, guaranteed bridging property with resin;
4, can control phenomenons such as glass fibre belt fluffing, displacement, embrittlement effectively, improve mechanical strength, purify environment, make things convenient for construction;
5, adopt advanced ultrahigh speed weaving technology, the selection of science, improved product quality and production efficiency.
6, make characteristics such as strong, the thermoelectric institute of good, the heat-resisting ageing resistance of its material wettability performance is good with resin, thereby, have good value for applications.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (1)
1. compound silane alkali-free glass fiber band comprises warp and parallel, it is characterized in that warp and parallel are to be coated with stranded the forming of glass fibre with silicon bi-layer alkane coupling agent by the surface, and warp is through in the middle of the parallel.
