Line wheel is placed on coil holder by step S3 by conducting wire as defined in drawing and around radical, between coil holder and coil winding machine away from
Can be closer when conducting wire radical is less from for 3-5mm, when conducting wire radical is more, then it should prevent conducting wire knob from existing from far
One card lifting wound insulation.Line wheel on coil holder is divided into two branches, faces winding former, the conducting wire of the right branch is drawn from the left side
Come, the conducting wire of left side branch is extracted from the right, then by two groups of wires cross of extraction, it is left around to it is crisscross such as Fig. 2
It is shown.If oval coil is right around to crisscross opposite.
Two groups of conducting wires after intersection are passed through noseplate by step S4 in order, and stacked two groups with conducting wire clamping plate
Conducting wire is clamped, so as to reason conducting wire suitable in coiling.Before oval coil, first around one layer (or) 0.08 on insulating paper cylinder
Site sized paper.Around preventing elliptical line from enclosing and damage insulating paper cylinder immediately from oval coil lower end when coiling.
Step S5, by as defined in drawing around to length of lifting one's head, conducting wire is bent and makes lifting one's head for oval coil.A left side around
It is bent to the right to oval winding protruding head, the right side is bent to the left around to oval winding protruding head.Specific bending method, comprising:
1) the standardized label on template conducting wire, is then placed in elbow tool, makes its label alignment elbow tool
Conducting wire is bent an angle of 90 degrees by column center.
2) will lift one's head after wire tensioning, template conducting wire, which will be placed on, to be reserved after lifting one's head length, and press above the conducting wire of bending
Wire turn is made corresponding label by conducting wire template, the long+30mm as shown in figure 3, L=lifts one's head；Wide+the 2mm of A=conducting wire.
3) according to the practice of bending template conducting wire, each wire is bent with elbow tool.The insulation of conducting wire bending part if any
Damaged part should be removed and mend packet to the thickness to insulate by breakage.
The wrapping of step S6, insulation of lifting one's head are wrapped up since the inside 10~15mm in bending place, gradually thick extremely to hold insulation position
Insulation thickness as defined in pattern, when wrapping with 0.05 crimped paper, two layers of half lap after specific thickness, outermost layer straight grain calico
One layer of half-lap of band.
Step S7 will be lifted one's head with clamping tool and be fixed on after reserving the one section of vertical spacer length that can place end insulation
On winding former.
Step S8 places the insulation of first layer end, and end insulation will stretch out 5~10mm of insulating paper cylinder when placement, and starts around the
One circle line.When around the first circle line, one side while around while below wire turn circumferentially uniformly place 4~6 at axial tightening band.It (draws
Taut band a part pyrocondensation belt, the special nylon rope of a part, positioning are circumferentially alternately placed), it is exhausted that puller strap one end is placed on end
Between edge and insulating paper cylinder, the other end is pressed under wire turn, as shown in figure 4, including in figure: conducting wire 1, axial tightening band 2, end insulation
3, winding former fagging 4 and root puller strap 5 of lifting one's head.On the other hand, while around while on the position of the radial size half of parallel conducting wire
Place axial cushion block, when coiling, cushion block and telephone paper, with conducting wire around axial cushion block will stretch out the first circle together with telephone paper
It is pressed in outside line in the insulation of first layer end, but cannot be concordant with end insulation, be there are certain nargin, the first circle is around complete rear placement the
The cushion block stretched out outside wire turn is pressed in that following (opening should be placed on conducting wire and lift one's head position by the insulation of two layers of end, the insulation of second layer end
On).
Step S9 places 0.5mm insulation paper groove on the wire turn adjacent thereto of oval winding protruding head root, and uses straight grain
Strap is tied up on wire turn, is seen Fig. 5, is included in figure: conducting wire 1, axial tightening band 2, end insulation 3, winding former fagging 4, root of lifting one's head
Puller strap 5 and insulation paper groove 6.Insulating paper flute length 100mm or so.
Step S10 when around the second circle, will bear against that end puller strap under the second circle line and translate into come above, around third circle
When, the second circle is rolled up to that end puller strap come and is pressed in the together with that end puller strap for being pierced by between insulating paper cylinder of end insulation
Three circle lines in the following, and tense, thus end insulation is tied together with the first circle line, will bear against third circle line when around four circles again
Under puller strap roll up come, circuitously oval coil is tensed in this way, sees Fig. 5.
Step S11, putting a puller strap in oval winding protruding head root makes it barocline on the 2nd, 3 circles, then routs up, should
The length of puller strap is greater than the axial height of oval coil, can be used to fasten the last circle conducting wire, see Fig. 5.The drawing
The online turn-to-turn of taut band must carry out braiding placement, and oval coil both ends are respectively compiled 4 times, and braiding is not had among oval coil, but
Puller strap has to translate into be come above line layer.
Step S12, all wire turn side braidings tense band edge and are close to wooden mallet, guarantee that entire oval coil is closely neat；
When coiling, as soon as cushion block is finished curtain at any time, continue a curtain inward at any time.
Step S13, pattern regulation double-screw type ellipse coil use "-secondary uniform crossover transposition " without exception, i.e. transposition is equal
It is distributed on oval coil evenly, transposition number is equal to double helix parallel connection radical, each transposition, by the most upper of line cake
One, face conducting wire moves to another line cake topmost, while the conducting wire of the bottom of another line cake one is moved to this line cake most
In the following, upper and lower transposition is shown in Fig. 6 at cross-like, by whole transpositions, the conducting wire of a line cake is successively changed into another line cake,
Then former line cake position is gained again, sees Fig. 7.When oval coil around change at drawing when, the telephone paper of transposition is cut,
Then it replaces.
It is " first (external in the insulation paper groove of the crook " S " parallel fabric band packet 0.5mm thickness when S ' is curved with record book in accordion form at wire transposition
The paper groove mouth that replaces is upward, and inside transposition paper groove mouth is downward), when then carrying out bending, or needing tool bending, first bending, and will
The wire insulation of bending part breakage is peelled off, then mends packet to former insulation thickness, and the paper groove of packet insulation later is exhausted with adjacent wires to guarantee
Edge is reinforced.After having changed position, the cushion block of transposition is correspondingly placed along radial, to ensure that oil duct is radial in parallel conducting wire always
On the position of size half.
Step S14, conducting wire welding should be prevented using silver-bearing copper board, and the welding at the position far from oval coil is overlapped
Welding slag splashes on oval coil, and the lap of splice should be not less than 5 times of conductor thickness.When welding, conducting wire and carbon block are connect
Touching well (by carbon block surface filing) can not will have the phenomenon that " point contact ", otherwise can be due to conducting wire hot-spot by conducting wire
It burns out.
Conjunction floor push is stepped on, is powered on, conducting wire weld is heated to crimson color, then continues to protect conducting wire to electricity
This temperature is held, silver-bearing copper welding rod is smeared along entire weld edge, after melting welding rod and being full of entire weld seam, is cut off the power,
Weld clip can not be shed after cutting off the power immediately, can not relax or shake, because at this moment solder not yet solidifies completely, weld seam holds very much
It is easy to crack.
File removes the wedge angle burr of weld, and after sand paper and the sanding of steel wire brush, scratch brushing, wrapping insulation is flat for paper bag
Copper wire, weld-be placed below 0.5mm insulate paper groove one, if the upper and lower faces of plumb joint have conducting wire,
Then plumb joint upper and lower two and should all place insulation paper groove, then wrap the thickness of former turn insulation again.Soldering tip, which is absolutely avoided, to be padded
At block, to be mutually staggered 80mm or more in same circle, and around the soldering tip of radical.
Step S15 carries out bending and insulating wrapping to complete head according to the same method of step S5 and S6.
Step S16 needs pre-buried 4~6 axial tightenings under wire turn in advance when oval coil is around to 4 circle of least significant end
Band (tenses a part of pyrocondensation belt, 2 special nylon ropes of a part, they are alternately placed), is pressed under wire turn (note after weaving 2 circles
Meaning, puller strap will bury a bit, with facilitate lift one's head and hold insulation be inserted in), by complete head bending wrap insulation after, with end insulate together
It penetrates in this several pre-buried puller strap sets and fixes end insulation with wire turn puller strap tension (extra puller strap is cut),
The puller strap for root of starting is fixed with the last circle again finally, sees Fig. 5.
Step S17, oval coil is after complete, in two ends of oval coil with two layers of pyrocondensation belt half-lap, to prevent
Only elliptical line encloses last head rebound.Oval coil is compareed drawing, checked item by item again after complete, and checks line with megger
Between whether have a short dot, after true zero defect, oval one layer of coil outermost layer half-lap half-dried no latitude glass adhesive tape (note:
Half-dried no latitude glass adhesive tape has to wind since oval coil lower end, and adhesive tape is damaged when preventing high and low pressure to be set with).
Oval coil need to meet the regulation deviation of following table 1.
Table 1
Step S18, is finally bound with nylon tape, the wood block filler below nylon tape and oval coil contact and pad
