Abstract
The invention provides a manufacturing method of a transformer coil. The manufacturing method comprises the following steps of (A1) winding a coil and isolating an inner layer of coil from an outer layer of coil through a cushion block; (A2) polishing the end parts of the inner layer of coil and the outer layer of coil and leveling the end parts; (A3) painting putty powder on the end parts; and (A4) spraying an insulating material on the end parts and solidifying the insulating material. The manufacturing method has the advantages that a transformer is good in working performance and beautiful.
Description
Technical field
The present invention relates to transformer, particularly to the manufacture method of transformer coil.
Background technology
Power transformer is one of capital equipment of power plant and electric substation.The effect of transformer is many, not only
High voltage can be risen and electric energy is delivered to electricity consumption area moreover it is possible to voltage is reduced to use voltages at different levels, to meet the needs of electricity consumption.
Power transformer includes iron core and its outer coil.In the winding process of coil：Use between every layer line circle
Insulating materials is isolated, such as insulating paper or cloth, the certain thickness of the overhang tool winding, surface irregularity；In order to improve absolutely
Edge performance, smears epoxy resin in end.
Content of the invention
For solving the deficiency in above-mentioned prior art, the invention provides a kind of manufacture method of transformer coil,
Improve the flatness of transformer coil end, ensure that the insulating properties of coil simultaneously.
The purpose of the present invention is achieved through the following technical solutions：
The manufacture method of transformer coil, described manufacture method comprises the following steps：
(A1) coiling, is isolated by cushion block between internal layer, outer coil；
(A2) polishing internal layer, the end of outer coil, make end smooth；
(A3) smear powder of lacquer putty for use in described end；
(A4) insulating materials is sprayed on described end and solidifies.
According to above-mentioned manufacture method it is preferable that described insulating materials is epoxy resin.
According to above-mentioned manufacture method, alternatively, described end is the group of the end of insulating materials between every layer line circle
Close.
According to above-mentioned manufacture method it is preferable that arranging described cushion block between internal layer, the part of outer coil.
Compared with prior art, the device have the advantages that being：
1., by striking off end, improve flatness and the aesthetics of end；
2. insulating materials is sprayed on end, the lamellar insulating barrier of shape is it is ensured that insulation effect；
3. by smearing powder of lacquer putty for use on it is ensured that the intensity of end.
Brief description
Referring to the drawings, the disclosure will be easier to understand.Skilled addressee readily understands that be：This
A little accompanying drawings are used only for illustrating technical scheme, and are not intended to protection scope of the present invention is construed as limiting.
In figure：
Fig. 1 is the flow chart of manufacture method according to embodiments of the present invention.
Specific embodiment
Fig. 1 and following description describe the optional embodiment of the present invention instructing those skilled in the art how to implement and
Reproduce the present invention.In order to instruct technical solution of the present invention, some conventional aspects are simplified or have eliminated.Those skilled in the art should
This understanding is derived from the modification of these embodiments or replacement will within the scope of the invention.Those skilled in the art should understand that under
State feature can combine in every way to form multiple modifications of the present invention.Thus, the invention is not limited in following optional
Embodiment, and only limited by claim and their equivalent.
Embodiment：
The flow chart that Fig. 1 schematically illustrates the manufacture method of the transformer coil of the embodiment of the present invention, as Fig. 1 institute
Show, the manufacture method of described transformer coil comprises the following steps：
(A1) coiling, is isolated by cushion block between internal layer, outer coil, setting insulation only between the coil of part
Cushion block；
(A2) polishing internal layer, the end of outer coil, make end smooth, described end is the insulation material between every layer line circle
The combination of material (as insulating paper, empire cloth etc.)；
(A3) smear powder of lacquer putty for use in described end；
(A4) insulating materials such as epoxy resin is sprayed on described end, forms very thin, smooth insulating barrier, and solidify.
Claims (4)
