Description
Technical field.The invention belongs to electric power technical machinery field, relate to power transformer winding former stepping technology.
Background technology.Power transformer winding before the coiling, needs by the requirement of artwork the winding former periphery to be carried out stepping earlier on vertical coil winding machine.Technology to the requirement of stepping is: according to the requirement of transformer coil wire winding figure, as shown in Figure 1, be placed on the vertical coil winding machine rolling disc (being commonly called as floral disc) 2 winding former 1 and both central lines, see center line 3, direction of rotation 4 expression winding formers 1, vertical coil winding machine rolling disc 2 synchronous direction of rotation; Wire winding requires each grade tell to be not more than usually ± 2 millimeters in the error in length of periphery (in as Fig. 1 between the gear 5 and 6 arc length); Support bar is placed on the position shown in the plumb line 7,8 among Fig. 1.
In order to realize above-mentioned requirements, existing stepping technology employing method is as follows: shown in Fig. 2 (a), turn chi (base of chi the has level meter) plumb line 9 that draws with long right angle on winding former 1 periphery; Then, shown in Fig. 2 (b), respectively around a paper tape 10,11, the method that is trapped among the winding former outer surface with paper tape is measured winding former outer surface girth actual value at place, two ends, the winding former face of cylinder; Because technology stepping sum is an even number, to survey measured two paper tapes takes off, adopt the method for paper tape doubling to divide equally, two paper tapes after doubling is divided equally enclose winding former outer surface origin-location again again, as Fig. 2 (c) 10,11 shown in, 12 expressions each break (stepping point) of paper tape up and down wherein among the figure; Shown in Fig. 2 (d), rotate paper tape, each break 12 of paper tape is up and down overlapped with plumb line 9, such two paper tapes 10,11 are just decided in the position on winding former 1 face of cylinder, fix two paper tapes; Next just can be from plumb line 9 beginning along paper tape each corresponding break up and down, other straight lines 13 etc. that draw successively, shown in Fig. 2 (e), these straight lines are exactly the stepping line; After painting all the stepping lines on the winding former face of cylinder, be pressed into support bar at each stepping line position, the winding former outer surface after the completion is shown in Fig. 2 (f); Arrive this, the stepping end-of-job.
In the example of Fig. 2, winding former is divided into 24 grades, and 24 bracing bars are put on each gear straight line of winding former outer surface.
As above-mentioned, because winding former adopts artificial stepping method, its weak point is: time-consuming, the effort of stepping is prone to the stepping mistake.
Summary of the invention.The object of the invention provides the automatic stepping method of a kind of power transformer winding former, compares with existing artificial stepping method and can improve stepping operating efficiency, assurance stepping precision.
Technical scheme of the present invention is: as shown in Figure 3, use original winding former 1 on the vertical coil winding machine, vertical coil winding machine rolling disc 2, vertical coil winding machine rolling disc central shaft 15, central shaft and winding former rotation angle measurement encoder driving belt 16, winding former rotation angle measurement encoder drive 17, winding former rotation angle measurement rotary encoder 18, rotary encoder data line 19, touch-screen 20, PLC cyclelog 21, frequency converter 22, variable-frequency motor 23, gearbox 24, vertical coil winding machine rolling disc meshing gear 25 grades and the individual components laser rays generator that increases newly the 14 common winding former rotational angle supervisory control systems of forming; This supervisory control system finishes jointly that winding former quantitatively rotates in the stepping process, stopping a train at a target point control under the stepping subprogram is supported, thereby realizes the function of the automatic stepping of winding former.
As shown in Figure 4, laser rays generator 14 is made up of cylindrical lens 29, spherical suspended axle 30, laser rays generator shell 31, laser shielded box 32, diode laser 33, round metal taper weight 34, laser rays generator mount pad 37 etc.; Cylindrical lens 29 center lines are parallel with round metal taper weight 34 center lines; Formed a fan-shaped laser beam plane 38 in the angle that fan-shaped laser rays outside along the line 26 and 27 is formed; Cylindrical lens 29, spherical suspended axle 30, laser shielded box 32, diode laser 33 quality sums are compared and can be ignored with round metal taper weight 34, therefore under the terrestrial gravitation effect, the integral body that cylindrical lens 29, spherical suspended axle 30, laser shielded box 32, diode laser 33, round metal taper weight 34 are formed becomes " single pendulum " in the physics, is a vertical laser beam plane so fan-shaped laser beam plane 38 remains in the space; This shows that to project the light 28 on winding former 1 face of cylinder must be a vertical light to laser rays generator 14 among Fig. 3.
Original touch-screen picture is made amendment on the vertical coil winding machine of need, newly-increased three automatic stepping action buttons (stepping startup, stepping, stepping stop) and a stepping value input window.
Because for the subprogram that PLC increases newly is no longer called behind the automatic stepping end-of-job of winding former, so the subprogram that increases newly does not influence the normal operation of the original program of PLC in the existing vertical coil winding machine; Winding former rotational angle supervisory control system finishes under the subprogram support in the automatic stepping process that the winding former angle is quantitatively rotated, stopping a train at a target point control; As shown in Figure 7, be linked to be a broken line 39 by OB, BC, CD, DE, EG, GJ isoline section, broken line 39 has determined the accuracy of each stepping angle value on the winding former, the Mathematical Modeling of broken line 39 is quantitatively described by the subprogram that increases newly, therefore the Mathematical Modeling quantitative response of broken line 39 corresponding relation of winding former rotation angle measurement encoder output pulse value with the variable-frequency motor rotational frequency, thereby realized to winding former carry out fast, the function of accurate, automatic stepping.
