Aiming at the disadvantages in the prior art, the buffered wire wrapping method of the wound rectangular high-voltage winding is provided. A device mainly comprises a frequency changer, an upper computer, a buffer cylinder, an encoder, an uncoiling motor, an uncoiling wire coil, a floating roll and a winding machine; the problems that when the rectangular winding is wound, the tension cannot be reduced, the insulating layer of the wire is damaged, and the wire is subjected to plastic deformation or even is pulled apart in the prior art are solved; in the application range of the method, good effects are produced in the tension fluctuation restrain in a manufacturing process of the rectangular winding; and qualified rectangular windings can be manufactured for transformer enterprises, and the production efficiency is improved.
Description
Technical field
The invention belongs to the Transformer Winding winding field, what relate in particular to a kind of coiling rectangle high pressure winding has a buffer winding method.
Background technology
The variation on during coiling rectangle winding because the length limit of mould can make wire speed can produce significantly fluctuation, and winding whenever rotates a circle and just has the flex point that makes the linear velocity sudden change for 4 times; Rectangle winding period of waves when rotated is 180 °, take profile as 232mm * rectangular mould of 85mm chamfering R10 is the example analysis, when winding speed is 20rpm, die shape parameter input MATLAB is simulated, from the figure that obtains, can find out, the linear velocity of wire is since 0 ° of acceleration, in the time of 15 °, reach the peak value 265mm/s of linear velocity, just reduce speed now subsequently, in the time of 90 °, drop to lowest speed 100mm/s; Acceleration at this period inner analysis wire can be seen, the acceleration of wire is for just between 0 ° ~ 15 °, illustrate on the wire and by the generation of winding main shaft traction wire tension force is arranged, the acceleration of wire has become negative value between 15 ° ~ 90 °, illustrate that this moment, tension force was zero, linear velocity and the acceleration of 90 ° ~ 180 ° interval and 0 ° ~ 90 ° are symmetrical, and just acceleration and deceleration and tension variation all are opposite; The variation of wire is more special in the time of 90 °, and to the conversion of long limit, wire becomes acceleration mode by deceleration regime to winding at once by minor face within the of short duration time; The acceleration of wire also instantaneous from negative value become on the occasion of; With momentum theorem wire tension is analyzed as follows: F in FT=M * Δ V formula---the tension force N that wire bears, the time s of T---change of line speed, M---wire quality kg, the changing value m/s of Δ V---linear velocity; Within the moment of wire velocity variations, M is fixed value, and Δ V and T are closely-related with the speed in when coiling, time T shortens rapidly when speed is increased to a certain degree, Δ V change of line speed increases simultaneously simultaneously, the result that both act on simultaneously is exactly that tension force F on the wire increases, and the insulating barrier of the lighter's wire is damaged after tension value surpasses the scope that the elastic deformation of wire allows, and the severe one wire will produce plastic deformation even break.
Summary of the invention
What the purpose of this invention is to provide a kind of coiling rectangle high pressure winding has a buffer winding method, solve in the prior art coiling rectangle winding and can't reduce the wire tension fluctuation, caused the insulating barrier breakage of wire and the problem that wire will produce plastic deformation even break.
In order to achieve the above object, the present invention is by the following technical solutions: a kind of coiling rectangle high pressure winding the buffer winding method arranged, adopt the device that is mainly formed by frequency converter, host computer, bounce cylinder, encoder, uncoiling motor, uncoiling drum, dancer and up-coiler, wherein frequency converter is connected with host computer, host computer is connected with bounce cylinder, bounce cylinder is connected with dancer, frequency converter is connected with encoder, encoder is connected with the uncoiling motor, the uncoiling motor is connected with the uncoiling drum, and the uncoiling drum is connected with up-coiler by wire.
A kind of coiling rectangle high pressure winding the buffer winding method arranged, the buffer unit between uncoiling drum and up-coiler, with the roller that a cylinder supports is floated, roller is installed between two fixing rollers, wire is through stationary roll and by dancer jack-up; When wire tension is excessive with compression cylinder to absorb extra tension force, when wire tension too small in addition when losing then cylinder stretch out and tighten wire, cylinder plays the cushioning effect in a peak clipping Pinggu in the process of tension fluctuation; Only there is in addition buffer unit can not satisfy the needs of tension fluctuation fully, the mode of operation of uncoiling motor also needs to be speed follow the mode initiatively from passive counter-rotating stringing lead mode altering, host computer calculates the average linear velocity of the wire under current up-coiler rotating speed according to the overall dimension of mould or winding, this numerical value is passed to the frequency converter that drives the uncoiling motor, on the one hand uncoiling motor stabilizing ground is to the line sending of coiling pusher side, and the fluctuation of buffer gear inhibition wire tension just can make and hold winding and reel reposefully on the other hand.
The invention has the beneficial effects as follows: solved in the prior art coiling rectangle winding and can't reduce the wire tension fluctuation, cause the insulating barrier breakage of wire and the problem that wire will produce plastic deformation even break, the inhibition for tension fluctuation has produced preferably effect in the production process of rectangle winding in the scope that is suitable for, and can help Transformer Enterprise to produce rectangle winding of fine qualities and enhance productivity.
