Abstract
The invention relates to the technical field of transformer coil winding, and specifically relates to a winding method of a multi-layer cylindrical coil of a transformer. The method comprises the following steps of: (1) mounting a winding former, and bending a wire to be provided with an end at 90 DEG by a tool according to a given winding direction, wherein the length of the end is in a given size; (2), winding a layer of lattice point coating paper on an insulating cylinder before winding, and temporarily binding by a cotton tape; (3), bending an end insulator to be arc-shaped, pressing cable paper of the end insulator by the wire at the beginning of winding, and putting away the end insulator when the last turns of the coil are left. When one layer of the coil is wound, a layer insulator is placed so as to effectively guarantee the insulation distance between each two adjacent layers of the coil, the voltage between each two adjacent layers of the coil is reduced, and the magnitude of partial discharge is reduced so as to guarantee the safe and reliable long-term operation of the transformer and prolong the service life of the transformer.
Description
Technical field
The present invention relates to the transformer coil winding technical field, be specifically related to the winding method of transformer multi-layer cylinder formula coil.
Background technology
At present, the loop construction of existing most power transformer products all adopts traditional multi-layer cylinder formula loop construction.And to guarantee the safety and reliability of transformer long-time running, the insulation distance between its coil just must guarantee.Because the insulation distance of traditional multi-layer cylinder formula loop construction is large, causes voltage between layers excessive, partial discharge quantity is large.
Summary of the invention
The purpose of this invention is to provide a kind of winding method that can guarantee the insulation distance between coil, reduction coil interlayer voltage, reduce the transformer multi-layer cylinder formula coil of partial discharge quantity, assurance product safety, reliable long-time running.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the winding method of transformer multi-layer cylinder formula coil may further comprise the steps:
(1), winding former is installed, with wire in accordance with regulations around to, be converted into 90 degree with instrument and lift one's head, the length of lifting one's head of reserving reaches given size;
(2), before the coiling on insulating cylinder around one deck site sized paper, and with the interim colligation of strap;
(3), will to hold insulation to be bent into circular-arc, when beginning to wind the line, pushes down the cable paper of end insulation with wire, around to last surplus a few circle the time, puts the end insulation well;
(4), when coil around when finishing one deck, place layer insulation;
(5), when coil around when the oil duct, oil duct is placed in the position in accordance with regulations;
(6), the adjacent layer wire rise the layer position 50～60mm that mutually staggers, and add the folded one deck crimped paper of bag;
(7), at coil when minute wiring is arranged to outermost layer or inferior skin, its position on request, former line is looped and is drawn, its length is 150mm, loop the place near coil medial pad 0.5mm paper groove, and together with mending the bag insulation in each 30mm scope of wire root both sides, colligation is fixed on the adjacent turns;
(8), coil after complete, with contraction bands half-lap one deck, both ends are done to strengthen processing, can be how around two-layer at its outer surface;
(9), unload lower coil, be placed on the coil bracket, prepare to enter next procedure.
The present invention has following beneficial effect: the winding method of transformer multi-layer cylinder formula coil of the present invention, employing at coil around when finishing one deck, place layer insulation, thereby can effectively guarantee the insulation distance between coil, reduce coil interlayer voltage, reduce partial discharge quantity, finally can guarantee product safety, reliably long-time running, and prolong its useful life.
Embodiment
Below the present invention will be further described in detail.
The winding method of transformer multi-layer cylinder formula coil may further comprise the steps:
(1), winding former is installed, with wire in accordance with regulations around to, be converted into 90 degree with instrument and lift one's head, the length of lifting one's head of reserving reaches given size; Lift one's head the insulation damages part for what draw because of instrument, should peel off and again bandage with crimped paper;
(2), before the coiling on insulating cylinder around one deck site sized paper, and with the interim colligation of strap;
(3), will to hold insulation to be bent into circular-arc, when beginning to wind the line, pushes down the cable paper of end insulation with wire, around to last surplus a few circle the time, puts the end insulation well; It should be noted that placing the thickness that insulate for every layer matches by conductor thickness, adjacent layer end insulation thickness deviation can not be overgauge or minus deviation simultaneously;
(4), when coil around when finishing one deck, place layer insulation; Need to prove that here the number of plies and the material of layer insulation are put on request, width is slightly larger than several millimeters of wire axial heights, and can not surpass the end insulation; Layer insulation requires classification to place, and notice that the joint of two graded insulations does not affect the coil width of cloth to size, staggers mutually between the insulation of each layer of layer insulation, and distance is about 10mm, and lap joint partly is not less than 10mm;
(5), when coil around when the oil duct, oil duct is placed in the position in accordance with regulations; In the present embodiment, can place paperboard strip or corrugated board, tight with the interim colligation of strap first during placement, if corrugated board, overlap does not affect the width of cloth to size, otherwise takes to flatten the way control oil duct size that beats out;
(6), the adjacent layer wire rise the layer position 50～60mm that mutually staggers, and add the folded one deck crimped paper of bag; Wherein, every layer of number of turn allows according to the change of coiling situation, but will be refilled before the coiling end, and guarantees that total number of turns and the tap number of turn, coil rise, a position, end meets the requirements;
(7), at coil when minute wiring is arranged to outermost layer or inferior skin, its position on request, former line is looped and is drawn, its length is 150mm, loop the place near coil medial pad 0.5mm paper groove, and together with mending the bag insulation in each 30mm scope of wire root both sides, colligation is fixed on the adjacent turns; In winding process, wire tensioning be guaranteed the coil winding consolidation, oil duct is unimpeded, and the coil surfaces externally and internally is without suspension trimming and strap;
(8), coil after complete, with contraction bands half-lap one deck, both ends are done to strengthen processing, can be how around two-layer at its outer surface;
(9), unload lower coil, be placed on the coil bracket, prepare to enter next procedure.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
