The winding former consists of former clamping plates, circular steel rings in the former, a former assembling fastener and steel ring insulating guard plates, wherein the circular steel rings inside the former are mounted in notches of the former clamping plates, the former clamping plates are fixedly mounted on the axis of the former via the former assembling fastener and include a former outer clamping plate and a former inner clamping plate, and the former outer clamping plate is connected with the former inner clamping plate via the insulating guard plates. The utility model provides a novel winding former manufacturing method. The winding former is fast in machining, low in material consumption and manufacturing cost and small in storage space, and can be suitable for various specifications of coil diameters.
Description
Technical field:
The utility model relates to a kind of transformer, relates in particular to a kind of winding former that is used for the transformer graded winding.
Background technology:
Coil in the circuit is meant inductor, it be one one of guide line around, lead insulate each other, and insulated tube can be hollow, also can comprise iron core or magnetic core, is called for short inductance.Inductance can be divided into fixed inductance and variable inductance again, and the fixed inductance coil is to be enclosed the land on insulated tube by one by lead one circle, and lead insulate each other, and insulated tube can be hollow, also can comprise iron core or magnetic core, is called for short inductance or coil.Between the circle of coil and turn-to-turn, coil and radome, the electric capacity that exists between coil and negative is called as distributed capacitance.The existence of distributed capacitance reduces the Q value of coil, bad stability, thereby the distributed capacitance of coil is the smaller the better.
The coiling of transformer coil is as follows: earlier around elementary winding, get the high-quality high strength enamelled wire close with former line footpath, two-wire and on " worker " font line shuttle is cut after the number of turns meets the demands.The two-wire head is sticked on the excircle of ring-shaped core with double faced adhesive tape, make the line shuttle in the endoporus of ring-shaped core, wear around.After one deck coil winds, brush one deck insulating varnish (helping wire turn location and insulation), and wrap one deck, again around second layer coil with glassine paper.After winding, the headtotail of two coils is made its series connection, two the end of a thread are drawn with the flexible wire welding in addition, and carry out insulation.Between adding from level to level on the elementary system group behind the insulating paper again around secondary winding, winding method and elementary winding winding are roughly the same.After all winding techniques finish, toroidal transformer is put into insulating box toast a period of time, so that the insulating varnish drying.Wrap with the thicker insulating paper of one deck at outermost layer, toroidal transformer has just completed again.
Wooden or the aluminium alloy mould of the general employing of traditional winding former, processing time consuming is taken material, the cost of manufacture height, and also the mould shelf space is big, in case design of transformer remodeling, mould will be scrapped, and make again.
The utility model content:
The purpose of this utility model is to be used for remedying the deficiencies in the prior art, and a kind of winding former that is used for the transformer graded winding is provided.
To achieve these goals, the technical solution of the utility model is as follows:
The winding former that is used for the transformer graded winding, this winding former is made up of round steel circle, mould equipment securing member and steel ring insulation backplate in mould clamping plate, the mould, the round steel circle is fixedly mounted in the notch of mould clamping plate in the described mould, and described mould clamping plate are fixedly mounted on mould shaft in the heart by the mould equipment securing member.
Described mould clamping plate comprise mould external splint and mould inner splint, and join by a plurality of insulation backplates between mould external splint and the mould inner splint.
The round steel circle is provided with breach in the described mould, and it is semi-enclosed steel ring.
Described insulation backplate is installed in the notch that is provided with on the mould clamping plate.
The notch diameter difference of described mould clamping plate.
The thickness of described insulation backplate is 0.5mm.
The thickness of round steel circle is 2mm in described.
Described mould external splint single face groove milling mouth, the two-sided groove milling mouth of mould inner splint.
The utility model provides a kind of novel mould making method, and its processing is fast, and it is few to take material, low cost of manufacture, and shelf space is little, and can reach the purpose that mold clamping plate are suitable for the coil diameter of plurality of specifications.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model structural representation
Fig. 2 is the schematic diagram of mould clamping plate in the utility model
Fig. 3 is an interior round steel circle schematic diagram in the utility model
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1: the winding former 100 that is used for the transformer graded winding, this winding former 100 is made up of round steel circle 300, mould equipment securing member 400 and steel ring insulation backplate 101 in mould clamping plate 200, the mould, round steel circle 300 is fixedly mounted in the notch 201 of mould clamping plate 200 in the mould, and mould clamping plate 200 are fixedly mounted on the mould axle center 102 by mould equipment securing member 400.
As Fig. 2: mould clamping plate 200 comprise mould external splint 201 and mould inner splint 202, and mould external splint 201 is symmetricly set on the both sides of mould inner splint 202, in the space that both form, wind the line, and join by a plurality of insulation backplates 101 between mould external splint 201 and the mould inner splint 202, insulation backplate 101 is fixed by the notch 203 that is installed on the mould clamping plate 200.With glass fiber lamination insulation board processing and fabricating two mould external splints 201 and mould inner splint 202, two external splints, 201 single face groove milling mouths, inner splint 202 two-sided groove milling mouths, groove width meets steel ring thickness, groove depth is 5mm, by the notch 203 of the different multiple different-diameters of internal coil diameter millable.
The utility model provides a kind of novel mould making method, and its processing is fast, and it is few to take material, low cost of manufacture, and shelf space is little, and can reach the purpose that mold clamping plate are suitable for the coil diameter of plurality of specifications.
