Abstract
A transformer winding expander used to regulate the oil gallery size of a coil includes an air bag and an air nozzle. The utility model has the technical proposal that the air bag subsequently includes a netlike framework layer and a glue layer from inside to outside; the netlike framework layer, the glue layer and the tubular air nozzle are sealed and arranged on one end of the air bag. The utility model can effectively make sure that the transformer and reactor coils can freely increase and decrease the number of coil padding block when supported by 2 to 4 air cushions in a layer of line segment, without damaging the insulation, which avoids damage of traditional operation methods to the coil turn insulation. The transformer winding expander has the advantages of simple and reasonable structure design, low manufacturing cost, elegant appearance, convenience in installation and maintenance, reliability and no leakage of the sealing structure, and convenience in connection after adoption of the plug-in connector. Use of the structure can bring good social and economic benefits to the transformer industry of our country.
Description
Technical field
The utility model relates to the power transformer technical field, specifically a kind of Transformer Winding expander that is used for regulating oil duct in making the power transformer process.
Background technology
In power industry, high-power transformer, reactor series products, in the manufacturing process of its coil, because strict specification requirement is arranged in the design, in the line segment of coil, to increase and decrease the size that cushion block is regulated oil duct, technological operation rules in the past are cushion block firmly to be pounded between the turn insulation of inlet wire circle with Chui, and this operation is easy to make the turn-to-turn insulation of coil to be destroyed.Turn insulation is in a single day destroyed, and the insulation property of product will weaken greatly, and the serious copper cash that causes is exposed, causes turn-to-turn short circuit, and the lighter's product burns, weight person's consequence and lose hardly imaginable.This primitive operation poor stability, labor strength is big, has not met the requirement of carrying out production strictly in line with rules and regulations now.
Summary of the invention
The purpose of this utility model provides a kind of Transformer Winding expander that is used for regulating winding oil duct size.
The purpose of this utility model is achieved in that it includes air bag, and valve is characterized in that: air bag is followed successively by reticulated bone rack-layer, glue-line, reticulated bone rack-layer, glue-line from inside to outside, and the sealing of tubulose valve is arranged on an end of air bag.
The purpose of this utility model also comprises following scheme, and it includes air bag, and valve is characterized in that: air bag is inside and outside double-layer structure, and layer structure is wherein established the rubber layer structure of one deck mesh skeleton layer at least in being, endothecium structure is the inflatable inner tube structure of sealing; The sealing of tubulose valve is arranged on an end of air bag.
The utility model can effectively guarantee transformer, reactor winding under the situation of not damaging insulation, supports by 2-4 air cushion in one deck line segment, and increase and decrease coil cushion block quantity has freely been stopped the destruction of traditional method of operation to the coil turn insulation.The utility model structural design advantages of simple, low cost of manufacture, good looking appearance, installation and maintenance is very convenient, the reliable ne-leakage of hermetically-sealed construction.Adopt plug hair style joint, easy to connect.Using of this structure will bring good social benefit and economic benefit as China's transformer industry.

Fig. 2 is the profile of Fig. 1.
Fig. 3 is an another kind of sectional structure simplified schematic diagram of the present utility model.
The utility model is described in further detail by example below in conjunction with accompanying drawing; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.
Embodiment
Embodiment 1:
Shown in Fig. 1～2,1 among the figure is air bag, and this air bag is followed successively by reticulated bone rack-layer 4, the rubber layer 5 of reticulated bone rack-layer 2, rubber layer 3, stretch nylon or the elastic polyester canvas of stretch nylon or elastic polyester canvas from inside to outside; Tubulose valve 6 adopts common metal tube to make, and this tubulose valve sealing is arranged on an end of air bag 1; The air bag one end edge that sealing is provided with tubulose valve 6 is provided with the glue-line boss 7 that increases sealing intensity.
Nylon or polyester canvas; The finished product of stretch nylon or elastic polyester canvas → single or double gluing → cut out → go up mouthpiece → air bag moulding → molded vulcanization → deburring → inspection back finished product packing warehouse-in.
Select multiple material framework materials such as oil resistant, light aging in anti-day, anti-ozone aging for use, framework material is the crucial raw material of this product.Should select intensity height, (elastic force) nylon or (elastic force) polyester canvas that unit mass is light for use, guarantee the intensity and the withstand voltage properties of finished product air bag.
Sizing material is selected: have good air-tightness energy, oil resistance and ageing-resistant performance in order to guarantee the winding expander, in when design prescription, should select acrylonitrile-butadiene rubber, neoprene, butadiene-styrene rubber, natural rubber, polyvinyl chloride, haloflex etc. one or more and be used as the material of canvas rubberised layer.
During use, when needing to regulate oil duct big or small in the line segment of transformer coil, earlier before unaerated, insert this structure between the turn insulation of coil, needed gap length between turn insulation then according to coil, inflate by tubulose valve 6, thereby realized the purpose of this utility model.
Embodiment 2:
By shown in Figure 3, among the figure 11 is air bag, this air bag is inside and outside double-layer structure, layer structure wherein for interior establish one deck reticulated bone rack-layer 13 two sides be respectively equipped with rubber layer 12 and 14, endothecium structure is the inflating rubber inner tube of a tyre 15 (being similar to balloon structure) of sealing; And 16 sealings of tubulose valve are arranged on an end of air bag.In addition, in order to increase the sealing intensity at tubulose valve 16 sealing positions, then be provided with the glue-line boss 17 that increases sealing intensity in the air bag one end edge that sealing is provided with tubulose valve 16.
This structure is identical about Material Selection and using method and embodiment 1.
