Fig. 2 is the utility model cross section diagram.
Number in the figure: 1 is bare copper flat wire, and 2 is highly dense heat-resisting turn-to-turn insulation ply of paper, and 3 is the 750KV insulating paper layer, and 4 is paraffin layer.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings below by embodiment.
Embodiment 1: ultra high voltage 1000KV reactor makes up paper covered wire with the field word
Carry out again axially side by side by two strands of radial composite conductors of making in advance, form the special sphere of movements for the elephants composite conductor of one of two spoke.These four lines are wide combination stack earlier, and leptoprosopy joins and arranges in order again, do not allow any dislocation mutually, depart to avoid super wide, the superelevation of size influence the current stabilization effect, also do not allow the gap simultaneously, see to illustrate 1.
Specifically, all apply highly dense heat-resisting turn-to-turn insulation ply of paper 2 outside 4 strands of bare copper flat wires 1 and constitute enameling copper strap wires, 4 strands of enameling copper strap wires are divided into 2 groups, earlier by two bursts of radial combinations of enameling copper strap wire, 2 enameling copper strap wires are coated with 3,2 bursts of superimposed places of enameling copper strap wire of 750KV insulating paper layer and are provided with 750KV insulating paper layer 3, make two groups of composite conductors, and then two groups of radial composite conductors will making axially make up, and form in the wrapped 750KV insulating paper layer 3 of periphery again.
The course of work of the present utility model is as follows:
First procedure is selection, selects the Chilean CCC cathode copper of high-quality import, uses the up-drawing method equipment that newly advances to draw the oxygen-free copper bar of Φ 12.5, and guaranteeing to draw the bar dimensional tolerance is positive and negative 2mm, and the soft copper bar is wanted defectives such as surperficial rounding, bright and clean, no burr, greasy dirt.
Second operation work is an extrusion process, use the Dalian T300 extrusion equipment of newly buying, carrying out bare copper flat wire 1 produces, tolerance is controlled at positive and negative 0.02mm, bending will be adjusted repeatedly, reach optimum controlling point, guarantee that the yield strength of bare copper flat wire 1 is controlled at 140～150Mpa, the Mould Machining center must cooperate this procedure to finish wire quality control.
The radial clustered operation of three process, this procedure is most important for the final overall dimension control of this special size, add that this lead requirement is close to bare copper flat wire 1 surface and must uses the highly dense heat-resisting turn-to-turn insulation ply of paper 2 of one deck import, insulating paper 2 tolerances configurations must will be controlled in advance to the thickness deviation that uses batch, calculates in advance make insulation thickness tolerance and lead tolerance coordinate to reach radial combined tolerances 0～+ 0.03mm is the best.Next requires the wrapped surface must be closely smooth, and nothing warps.
The 4th procedure is axial clustered operation; emphasis is the adjustment of the speed of a motor vehicle; the adjusting of wrapped tension force; the situation that whole then line process does not allow the radial composite conductor of any damage surface takes place, and it is unaffected etc. to note that the line process is protected cloud insulating surface quality and wrapped overlap joint size.
Five processes is the waxing operation, and at the chassis of composite conductor paraffine, paraffin layer 4 thickness evenly are 0.02mm.
The 6th procedure is to receive the winding displacement operation, and the take-up reel that winding displacement uses must be to handle the clean special ultra high voltage Special disc tool with dust prevention.Winding displacement is to guarantee the even no wrinkling insulating paper of cushioning between every layer line, guarantees that paraffin layer is not impaired at last drum.
