Abstract
The utility model belongs to the technical field of an internal air flue fixing structure of a transformer coil, and particularly relates to a dry type casting high-tension coil air flue strengthening structure which comprises a high-tension coil, wherein air flue plates are uniformly arranged on one side of the high-tension coil. The dry type casting high-tension coil air flue strengthening structure is characterized in that outer sides of the air flue plates are sleeved with glass fiber cloth; air flues are arranged in the air flue plates; and a casting structure is arranged between adjacent air flues. The dry type casting high-tension coil air flue strengthening structure is simple in structure and convenient to use, the dry type coil winding quality is improved, partial discharge and mechanical strength of products are reduced, and the disadvantage of high probability of cracking of the air flues is overcome; and the manufacturing cost is low, and popularization and application are facilitated.
Description
(1) technical field
The utility model relates to a kind of dry type cast high-tension coil air flue and strengthens structure, belongs to the inner air flue fixed structure of transformer coil technical field.
(2) background technology
Existing transformer coil air flue is in order to prevent air flue plate cracking, mostly transformer coil is directly used to air flue plate and felt coiling, but effect is also bad, owing to only having felt without glass fabric (cylinder), easily make the resin cracks after drying, particularly for the dry transformer high-tension coil of 6300kVA and above capacity, too much resin makes the air flue crack that overall rule differs from top to down, after coil drying forming, still exist because a large amount of resins make air flue plate problem of Cracking, brought very large puzzlement.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides a kind of simple in structure, thereby the transformer coil air flue that can make easy to use becomes the not dry type cast high-tension coil air flue reinforcement structure in crack of an organic whole.
The utility model is achieved by the following technical solution:
A kind of dry type cast high-tension coil air flue is strengthened structure, comprise high-tension coil, high-tension coil one side is evenly provided with air flue plate, it is characterized in that: described air flue plate outside cover has glass fabric, in air flue plate, be provided with air flue, between air flue and air flue, be provided with cast structure.
Wherein:
Described air flue is formed by glass fabric and resin-cast, cast structure is formed by felt and resin-cast, glass fabric, felt have good dry type coil mould material adsorption effect, can make mould material composition enter district in its space, become an organic whole, simultaneously felt is for the gap between the gentle guidance tape of regulating winding interlayer integral thickness, to reach stressed effect after good cast.
Described glass fabric adopts single layer structure, and the width of glass fabric, than the long 1cm-3cm of the width of air flue plate, wraps tightly air flue plate while being convenient to coil winding.
The utility model has changed original direct version with air flue plate and felt coiling, when coil winding, increase the shortcoming that glass fabric has just solved the easy crack of air flue, after glass fabric is dried casting resin, just as injecting reinforcing bar in concrete, whole air flue becomes an organic whole.
The beneficial effects of the utility model are: simple in structure, easy to use; The utility model has improved dry type coil winding quality, has reduced product office and has put and mechanical strength, has solved the shortcoming in the easy crack of air flue; Cost is low, easy to utilize.
(4) brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is the utility model front view;
Accompanying drawing 2 is the utility model vertical view.
In figure: 1, high-tension coil; 2, air flue plate; 3, air flue; 4, cast structure.
Embodiment
Accompanying drawing is specific embodiment of the utility model.
As Fig. 1, the utility model dry type cast high-tension coil air flue shown in Fig. 2 is strengthened structure, comprise high-tension coil 1, high-tension coil 1 one sides are evenly provided with air flue plate 2, described air flue plate 2 outside covers have glass fabric, in air flue plate 2, be provided with air flue 3, between air flue 3 and air flue 3, be provided with cast structure 4, air flue 3 is formed by glass fabric and resin-cast, cast structure 4 is formed by felt and resin-cast, glass fabric, felt has good dry type coil mould material adsorption effect, can make mould material composition enter district in its space, become an organic whole, felt is for the gap of 2 of the gentle guidance tapes of regulating winding interlayer integral thickness simultaneously, to reach stressed effect after good cast.
Wherein individual layer for glass fabric, be applicable to 10000KVA and above larger capacity coil winding, width is than the suitable wide 1cm-3cm in the every limit of air flue plate 2, or the glass fiber packages of the energy appropriateness cover downtake plate of preferably being made by glass fabric, be applicable to 6300 narrow and more～10000KVA of air flue 3 compared with small-capacity dry-type high-tension coil, while being convenient to coil winding, glass fabric wraps tightly air flue plate 2, makes cast-type coil, does not worry increasing with glass fabric the radial size of coil.
The utility model position limiting structure has changed the spacing form of existing anti-pressure nail, and its application makes that the iron core of box lid type transformer is fixing can be reached equally the spacing effect of anti-pressure nail and not limited by operating space.
