Abstract
The utility model discloses a disc coil with coiling of polygon enameled wire, including the insulating cylinder, set up at the stay of insulating cylinder outer wall, around putting the line cake on the stay, the line cake adopts the wire rod coiling of preimpregnation in insulated paint, the cross -section of wire rod is the polygon. The utility model discloses a disc coil adopts the coiling outside the stay of polygon enameled wire, contrasts traditional paper covered wire, and the polygon enameled wire need not to go on a packet paper, and the insulating layer is thin, and the coiling is convenient, and it is fast to convolute, and the line cake size of coiling is little, and is closely reliable between the wire turn.
Description
Technical field
The utility model relates to a kind of transformer coil, particularly relates to a kind of disk-type winding with the coiling of polygon enamel-covered wire.
Background technology
The coil of tradition open dry-type transformer adopts paper covered wire to turn to cake formula. Paper covered wire conventionally need at which floor paper of wire outsourcing, and the time cycle that bag paper step expends is long, and manufacturing cost is high, and the insulation of the paper covered wire obtaining is thicker, and the speed of coiling line cake is slow; Adopt after paper covered wire coiling line cake, also need to carry out dipping lacquer, in dipping lacquer process, to inhale the amount of paint larger for paper covered wire, after dipping lacquer completes, drips paint and dry time long, and production efficiency has much room for improvement.
Utility model content
For overcoming the problems referred to above, the purpose of this utility model is to provide a kind of disk-type winding with the coiling of polygon enamel-covered wire, and the class of insulation is high, without wrapping paper, can improve coiling speed, reduces production costs.
The technical solution adopted in the utility model is:
With a disk-type winding for polygon enamel-covered wire coiling, comprise insulating cylinder, be arranged on the stay of insulating cylinder outer wall, the line cake on stay around the home, described line cake adopts the wire rod coiling of preimpregnation in wire rod, and the cross section of described enamel-covered wire is polygon.
As the further improvement of technique scheme, the class of insulation of the enamel-covered wire that described wire rod obtains through preimpregnation is more than H level.
As the further improvement of technique scheme, between described line cake, adopt cushion block to separate, between cushion block, form air flue between cake, be conducive to airflow, accelerate coil heat radiation.
As the further improvement of technique scheme, described stay is comb stays, has been wholely set broach on stay, and described line cake is separated by broach. Air flue between the cake of the comb stays replacement cushion block formation line cake that employing is wholely set, can make the air flue distribution of coil more reasonable, reduces costs simultaneously, enhances productivity. The comb tooth spacing of comb stays can be uniformly distributed, and can also set according to the thickness of line cake, is formed with the comb stays of gradient.
As the further improvement of technique scheme, on described disk-type winding, be also provided with auxiliary stay for static line cake, described auxiliary stay is circle or polygon.
The beneficial effects of the utility model are:
Disk-type winding of the present utility model adopts the coiling outside stay of polygon enamel-covered wire, contrasts traditional paper covered wire, and polygon enamel-covered wire is without wrapping paper, and insulating barrier is thin, and coiling is convenient, and winding speed is fast, and the line cake size of coiling is little, closely reliable between wire turn.
In addition, the coil that adopts the coiling of polygon enamel-covered wire to obtain, can adopt paint-dipping process or paint-dipping process not, if adopt paint-dipping process, the required paint consumption of this coil is few, after dipping lacquer drying time short, can further shorten the production cycle and optimize production cost; If adopt a kind of damp-proof paint envelope curve, do not need paint-dipping process, technique is simpler.
Brief description of the drawings
Be described further below in conjunction with accompanying drawing and example.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of disk-type winding with the coiling of polygon enamel-covered wire that the utility model provides, comprises insulating cylinder 3, stay 2 and line cake 1. In the present embodiment, described stay 2 is comb stays, has equally distributed broach 21, stay 2 is close to insulating cylinder 3 outer wall settings, and described line cake 1 between the broach 21 of stay 2, is separated by broach 21 around the home, and form air flue between cake, be conducive to the heat radiation of circulation of air and coil. It is the above enamel-covered wire coiling of H level that line cake 1 adopts the class of insulation, and enamel-covered wire is that polygonal wire rod obtains after preimpregnation in insulated paint by cross section, because the insulation of polygon enamel-covered wire is thinner, adopts the winding volume of this enamel-covered wire coiling less.
Further, auxiliary stay can also be set for static line cake 1 on coil, described auxiliary stay is circle or polygon.
Disk-type winding of the present utility model adopts polygon enamel-covered wire in the outer coiling of stay 2, contrasts traditional paper covered wire, and polygon enamel-covered wire is without wrapping paper, and insulating barrier is thin, and coiling is convenient, and winding speed is fast, and line cake 1 size of coiling is little, closely reliable between wire turn. The coil that adopts the coiling of polygon enamel-covered wire to obtain, can adopt paint-dipping process or paint-dipping process not, if adopt paint-dipping process, the required paint consumption of this coil is few, after dipping lacquer drying time short, can further shorten the production cycle and optimize production cost; If adopt a kind of damp-proof paint envelope curve, do not need paint-dipping process, technique is simpler.
In addition, in other embodiments, can also adopt T shape stay to add the structure of cushion block, replace comb stays coil is supported.
The above, be preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
