Abstract
The utility model relates to the technical field of transformers, in particular to a layer coil structure of a transformer. The structure comprises an inner layer coil, an outer layer coil and an insulating layer, wherein the insulating layer is embedded between the inner layer coil and the outer layer coil, and comprises at least a piece of cable paper and a piece of polyester film; and the cable paper and the polyester film are laminated on each other, and are arranged in the winding way, and the polyester film is embedded between two pieces of cable paper. In the utility model, the cable paper and the polyester film are laminated on each other, and are arranged in the winding way to replace a traditional structure formed by winding gummed paper on a single mesh point; under the condition of the same obtained maximum operating voltage, the radial winding thickness of the cable paper and the polyester film is far less than the winding thickness of the gummed paper on mesh points; the radial sizes of the coils of the transformer are reduced, and in other words, silicon steel sheets and copper wires of the transformer are relatively saved to save materials and reduce manufacturing cost; and the aims of energy saving and consumption reduction are indeed achieved to increase the performance-price ratio of a product.
Description
Technical field
The utility model relates to the transformer technology field, refers in particular to the layer coil structure of transformer.
Background technology
The layer coil of traditional transformer, during making, layer insulation between the coil layer is to adopt the site sized paper of single character to twine acquisition, and this tactic pattern needs more site sized paper usually under transformer electric property and the guaranteed basis of mechanical performance, and the thickness of site sized paper is thicker, reach 0.13mm, the thickness height after the coiling, volume is big, also just cause more silicon steel sheet of needs and copper cash, thereby the cost of manufacture height.
The applicant is because the defective of the layer insulation structure of the layer coil of above-mentioned known transformer, the spirit of adhering to the research innovation, keeping on improving, utilize professional eye and professional knowledge, proposed a kind of layer insulation structure of layer coil of transformer of effective economical with materials.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, a kind of insulating material of different nature layer insulation structure of the stacked transformer coil that forms mutually that adopts is provided, this structure can be under transformer electric property and the guaranteed basis of mechanical performance, effectively dwindle the coiling thickness of layer insulation and the entire outer diameter of dwindling transformer coil, reach relative save silicon steel disc and copper cash, reduce consumptive material.
For achieving the above object, the utility model adopts following technical scheme:
The layer insulation structure of the layer coil of transformer, include inner coil, outer coil and be embedded insulating barrier between inner coil and outer coil, insulating barrier comprises a cable paper and a mylar at least, the mutual stacked winding of cable paper and mylar.
Described mylar is embedded between two cable papers; The thickness of cable paper is 0.08mm, and the thickness of mylar is 0.04mm.
The utility model adopts cable paper and the mutual stacked winding of mylar to substitute the structure that traditional single site sized paper twines, obtaining under the identical maximum working voltage basis, cable paper and mylar radially twine the thickness that thickness twines much smaller than the site sized paper, reach the radial dimension that has reduced transformer coil, just save the silicon steel sheet and the copper cash of transformer relatively, saved material, reduced cost of manufacture, really reached energy-saving and cost-reducing, promoted cost performance of product.
The utility model advantage again is simple in structure, and is scientific and reasonable, makes easily, promoted the feasibility and the operation ratio of transformer greatly.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult shown in Fig. 1,2, the layer insulation structure of the layer coil of the relevant transformer of the utility model, include inner coil 1, outer coil 2 and be embedded insulating barrier 3 between inner coil 1 and outer coil 2, insulating barrier 3 comprises a cable paper 31 and a mylar 32 at least, cable paper 31 and mylar 32 mutual stacked windings.
The utility model adopts cable paper 31 and mylar 32 mutual stacked windings to substitute the structure that traditional single site sized paper twines, under the basis that obtains identical transformer electric property and mechanical performance, cable paper 31 and mylar 32 radially twine the thickness that thickness twines much smaller than the site sized paper, reach the radial dimension that has reduced transformer coil, the silicon steel sheet and the copper cash of transformer have just been saved relatively, save material, reduce cost of manufacture.Mylar 32 employing standards are the electric insulation mylar of GB13950-92, and model is PET.
Embodiment:
When maximum working voltage is 10KV between making layer, traditional layer insulation structure needs 3 or the above thick site sized paper of 0.13mm to twine stacked winding at least, like this, the thickness of its layer insulation reaches more than the 0.39mm, and when adopting the mutual stacked winding of cable paper 31 and mylar 32, cable paper 31 and a thickness that only to need two thickness be 0.08mm are that the 32 stacked windings of 0.04mm mylar get final product, mylar 32 is embedded between two cable papers 31, the thickness of the layer insulation that forms only is 0.20mm, thickness much smaller than the winding of site sized paper, reach the radial dimension that has reduced transformer coil, just save the silicon steel sheet and the copper cash of transformer relatively, saved material.
Also can be in the enforcement of the present utility model according to actual requirement; many mylars 32 are distributed between many cable papers 31; also many mylars 32 can be layered in mutually between two cable papers 31; thereby above diagram; it only is the utility model better embodiment; be not to limit the scope of application of the present utility model, so everyly on the utility model principle, make equivalent change and all should be included in the protection range of the present utility model with this.
