Abstract
The utility model relates to a transformer coil comprising a winding stand and a copper bar. Narrow-strip shaped thin metal strips are connected in the length direction; the strips are connected with the copper bar and wound with insulating paper; spacing strips used for forming a heat dissipation air channel are arranged between winding layers; and the edges of the strips at two sides are connected with terminal insulating materials. Different coil specifications are adapted through regulating the number of the strips, so that the trouble of manufacturing individual metal foils for coils with different widths is avoided; and simultaneously, the time of waiting for the metal foils can be reduced, the order cycle time of the coils is shortened, the pressure that the circulating funds of an enterprise is substantially occupied is lightened, the machining charges of the strips are far lower than those of foils, and the machining cost is greatly reduced.
Description
(1) technical field
The utility model relates to a kind of transformer coil.
(2) technical background
Existing transformer coil be to form with whole Copper Foil or aluminium foil coiling, at first with metal forming plate dish on winder feeding rack, insulating material is installed on the blanket insulation bin again, then will hold insulating material to be installed on the end blanket insulation bin, calibration metal paper tinsel Board position afterwards, the metal forming plate is drawn to the winding former top, proofread and correct the insulating material position then, insulating material is drawn to the winding former top, adjusting the required width of insulating paper reaches bit position, the metal forming plate is welded on the copper bar that can be fixed on the winding former again, described copper bar is fixed on the winding former, one deck or two layers of insulation material are covered on the metal forming plate, will hold insulating material to be pulled to the winding two ends and cement, restart the coiling transmission device.The bin discharging, metal forming plate and insulating material and end insulating material are wound onto on the winding former simultaneously,, be provided with the parting bead that is used to form the heat radiation air flue between the volume layer, form the coil that needs.
The characteristics of this traditional whole paper tinsel formula transformer coil are the metal forming plates that the coil of making different in width need use corresponding width, therefore, enterprise must be according to the customized specific metal forming plate that requires of the concrete size of every order, because the processing charges costliness and the process-cycle of metal forming plate are long, cause long, with high costs, working capital of enterprises of delivery cycle to be taken in a large number.
(3) summary of the invention
Need use the shortcoming of the metal forming plate of different in width for the coil that solves the existing coiling different in width of existing transformer coil, the utility model proposes the transformer coil new construction that a kind of raw material that use a kind of specification just can the coiling different in width, with reduce cost, the reduction of erection time.
Transformer coil described in the utility model, comprise around frame, copper bar, it is characterized in that: the metal strip bar by shaped like narrow on Width is spliced, described tape all is connected with copper bar, described tape and insulating paper are reeled, the outer rim of the tape of both sides is connected with the end insulating material, is provided with the parting bead that is used to form the heat radiation air flue between the volume layer.
Further, described adjacent tape is abutted against mutually.
Perhaps, gapped between the described adjacent tape.
Described metal strap is copper or aluminium matter.
Transformer coil described in the utility model is spliced by tape on Width, when needing the coil of different in width specification, as long as increase or reduce the number of tape, just can change the coil width of institute's coiling.Thus, factory need not to have shortened the duration into the independent customized metal forming plate of the coil of every kind of width, has also reduced production cost.
In addition, because the performance of transformer coil and coil surface are long-pending relation is arranged, because lateral area increases, piecing together the paper tinsel plate of system has bigger surface area than whole paper tinsel plate, and therefore, the performance of the coil that its coiling forms is better than the coil of whole paper tinsel plate coiling.
The beneficial effects of the utility model are: (1) can adapt to different coil specifications by the radical of adjusting tape, avoided puzzlement for the coil manufacturing metal forming separately of different in width, also reduced the time of waiting metal forming simultaneously, shorten the delivery cycle of coil, alleviated the pressure that working capital of enterprises is taken in a large number; (2) the tape processing charges have greatly reduced processing cost well below paper tinsel.
(4) description of drawings
Fig. 1 is the schematic diagram of coiling of the present utility model.
(5) embodiment
Embodiment one
With reference to accompanying drawing, the utility model is described further below in conjunction with accompanying drawing.
Transformer coil described in the utility model, metal strip bar 1 by shaped like narrow on Width is spliced, described tape 1 all is connected with copper bar, described tape 1 is reeled with insulating paper 2, be provided with the parting bead that is used to form the heat radiation air flue between the volume layer, the outer rim of the tape 1 of both sides is connected with end insulating material 3.Described adjacent tape 1 is abutted against mutually.
Transformer coil method for winding described in the utility model comprises the steps:
A. make the metal strip bar 1 of shaped like narrow;
B. every strip metal tape 1 is twisted on the corresponding drum, each drum all is enclosed within on the main shaft of winder feeding rack, establishes dividing plate between the adjacent drum;
C. the head of each metal strap 1 is welded on the fixture on the winding former;
D. each metal strap 1 is drawn in, the sidepiece that makes adjacent metal tape 1 mutually against, metal strap 1 and insulating material 2 and end insulating material 3 are wound onto on the winding former simultaneously, form the coil that needs.
When metal tape 1 was copper strips, described fixture was a copper bar; When metal tape was aluminium strip, described fixture was aluminium row or copper bar.Described insulating material 2 and end insulating material 4 are preimpregnation cloth.
Earlier many metal straps 1 dish is gone into bin, then tape is passed through supporting mechanism, position-limit mechanism in order, strainer entirely comes the head of every tape 1 on the fixture and fixture and metal strap 1 is welded together successively, and this fixture is fixed on the winding former.Start the cylinder be installed in the strainer top and metal strap is applied suitable pressure make its tensioning, drive winding former, with many tapes 1 mutually near, be spliced into the state coiling that is similar to whole paper tinsel.
Embodiment two
With reference to accompanying drawing:
The difference of present embodiment and embodiment one is: gapped between the described adjacent tape 1.Because tape all is connected with copper bar or aluminium row, so the gap between the tape 1 does not influence its electric conductivity.
The described content of this specification embodiment only is enumerating the way of realization of inventive concept; protection range of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection range of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
