The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
At present, a high-voltage winding of a 10kV low-capacity distribution transformer adopts a multi-layer cylindrical structure, and a finished wire round wire and a finished wire flat wire are generally adopted during winding. The problems of small filling rate, low mechanical strength of the winding and poor short circuit resistance exist when the enameled round copper wire is adopted for winding. In order to improve the wire filling rate and the mechanical strength of the winding, a full-automatic winding machine with a flattening function is adopted for winding, a round wire is flattened into a wire similar to a runway shape, and the wire is wound on the winding. However, the size of the windings for the collapsing function cannot be determined, and thus the performance of the wire for the collapsing function cannot be determined.
Based on the above reasons, the embodiment of the present application provides a method for determining a wire parameter after an enameled round wire is flattened, as shown in fig. 1, the method includes the following steps:
step S102, obtaining flattening information corresponding to a plurality of groups of target enameled flat wires obtained after the initial enameled round wires are flattened;
step S104, determining section loss data of the target enameled rectangular wire relative to the initial enameled round wire based on the flattening information;
step S106, determining the arc angle of the target enameled rectangular wire based on the section loss data;
and step S108, determining the size parameter of the lead of the target enameled rectangular wire based on the flattening information, the section loss data and the arc angle.
The target enameled flat wire can be a winding wire with a flattening function, which is obtained by flattening an initial enameled round wire in different degrees.
The method for determining the wire parameters after the enameled round wire is flattened in the embodiment of the present application is further described below.
Aiming at the step S102, obtaining flattening information respectively corresponding to a plurality of groups of target enameled flat wires obtained after the initial wire parameter information of the initial enameled round wire is flattened, and the method comprises the following steps 2.1) to 2.3):
step 2.1), acquiring initial wire parameter information of the initial enameled round wire; the initial wire parameter information includes a wire diameter;
step 2.2), determining thickness information of a corresponding target enameled flat wire after the initial enameled round wire is subjected to squeezing with different squeezing thicknesses based on the diameter of the wire;
and 2.3) determining the flattening information of each group of target enameled rectangular wires based on the thickness information.
In an alternative embodiment, the wire diameter, i.e. the diameter of the initial enameled round wire, is denoted by d. And extruding and flattening the enameled round copper wires with the same diameter d by a winding machine to obtain enameled wires with different flattening thicknesses a. Corresponding thickness information may be obtained by measurement.
In order to ensure the reliability of the determined result, as much flattening of the round wire with a flattening thickness as possible can be performed. Meanwhile, in consideration of the efficiency of data processing, in an implementation manner, the embodiment may adopt 24 groups of conducting wires to be flattened by the winding machine, that is, the target enameled flat wires are 24 groups, and the flattening information of each group of target enameled flat wires is different.
Further, for the step 2.3), determining the flattening information of each group of target enameled rectangular wires based on the thickness information, and when the method is implemented, the method may include the following steps 3.1) and 3.2):
step 3.1), determining the proportional data of the thickness information and the diameter of the wire;
step 3.2), determining the flattening rate corresponding to each group of target enameled rectangular wires based on the preset percentage of the difference value between the target data and the proportional data; the flattening information includes a flattening rate.
In specific implementation, a formula can be adopted
Determining the flattening rate, wherein eta is the flattening rate; a is thickness information; d is the diameter of the wire; target data adopts 1;
the ratio data of the thickness information and the diameter of the wire. As shown in FIG. 2, before the extrusion, the left figure is shown, and after the extrusion, the right figure is shown. The diameter before extrusion is d and the thickness after extrusion is a.
In one embodiment, when 24 sets of wires are flattened, 24 sets of data a are measured to yield 24 sets of flattening ratios, as shown in table 1:
TABLE 1 statistics of 24 groups of wire data after flattening
Because the multiple groups of enameled flat wires obtained by squeezing to different degrees have different squeezing degrees, the flattening rates of each group of target enameled flat wires are different from each other.
For the step S104, determining the section loss data of the target enameled rectangular wire relative to the initial enameled round wire based on the flattening information, when implemented, the following steps 4.1) to 4.3 may be included:
step 4.1), measuring first section information of the flattened target enameled rectangular wire;
step 4.2), fitting the flattening rate and the first section information to obtain a fitting model;
and 4.3) determining the loss data of the section of the wire based on the fitting model.
In an alternative embodiment, the conductor section changed from the target enameled wire in the first section information bit may be cut from the flattened target enameled rectangular wire, such as a 1 meter long wire, and the section neps may be determined as the first section information. It can be understood that, since the target enameled rectangular wire is selected from a plurality of groups, the number of the corresponding first section information is the same as the number of the groups of the target enameled rectangular wire.
The section loss data can be the reduction percentage of the sectional area of the wire, and the reduction percentage of the sectional area of the wire under different flattening rates can be determined correspondingly through a plurality of pieces of first section information.
When the number of groups of the target enameled rectangular wires is set to 24 groups, fitting may be performed with 24 groups of flattening ratios as independent variables and 24 groups of reduction percentages of the cross-sectional area as dependent variables. In one embodiment, an Excel interpolation graph and polynomial fitting function may be used to obtain a fitting model that passes the polynomial y-11551 x6-10803x5+3894.3x4-680.36x3+61.248x2-2.6717x + 0.0436. From this fitted model, one can derivePercent reduction in wire cross-sectional area at different flattening ratios.
Further, after the flattening rate of the enameled rectangular wire is obtained later, the fitting model is input, and then the corresponding (section loss data) reduction percentage of the sectional area is obtained.
For the step S106, the arc angle of the target enameled rectangular wire is determined based on the section loss data, and when the method is implemented, the following steps 5.1) and 5.2) may be included:
step 5.1), measuring the linear length data of the flattened target enameled rectangular wire;
and 5.2) determining the arc angle of the target enameled rectangular wire based on the diameter of the wire, the thickness information of the target enameled rectangular wire, the first section information and the straight length data.
For the step 5.2), determining the arc angle of the target enameled rectangular wire based on the diameter of the wire, the thickness information of the target enameled rectangular wire, the first section information and the straight line length data, and when the method is implemented, the method may further include the following steps 6.1) and 6.2):
step 6.1), drawing a wire section image based on the wire diameter, the thickness information and the straight line length data;
and 6.2) measuring the arc angle of the section image of the wire, wherein the arc angle is the most target arc angle of the enameled rectangular wire.
In an alternative embodiment, the above-mentioned drawing of the wire section image based on the wire diameter, the thickness information and the straight line length data may further include the following steps 7.1) to 7.5):
step 7.1), drawing a wire section image based on the wire diameter and thickness information;
step 7.2), measuring second section information of the section image of the lead by using a drawing tool;
step 7.3), judging whether the second section information is different from the first section information;
step 7.4), if yes, correcting the straight line length data until the second section information is the same as the first section information;
and 7.5) drawing a wire section image based on the wire diameter and thickness information and the corrected linear length data.
To understand the above steps 7.1) to 7.5), referring to fig. 3, the wire after extrusion is in an oval-like shape (formed by connecting two equal arcs by two equal straight segments), assuming that b' is equal before and after extrusion, and the diameter d and the thickness a after extrusion are calculated according to the cosine theorem of triangle
In the formula
As shown in FIG. 4, the wire diameter d before flattening, the wire thickness a after flattening, and the wire cross-sectional area S after flatteningSqueeze and flattenThe long b' of straight line part after extruding adopts CAD to draw the wire section after extruding, specifically includes:
(1) drawing a circle with the diameter d, symmetrically drawing the distance of two dotted line segments with the circle center as a, and enabling end points at two ends of the line segments to be on the circle;
(2) deleting the circle, changing the line segment into a real line segment, taking the line segment endpoint as the first step, taking the circle center of the circular arc (the circular arc on the side after being flattened) as the second step, and taking the distance l1 (which is an unknown quantity and is represented by S)Squeeze and flattenDetermining) is the distance from the center of the arc center to the center;
(3) drawing a dotted line circle by taking the second point as the circle center and the end point of the first point as the point on the circle;
(4) cutting the redundant part to form the extruded and flattened wire with a cross section similar to a long circle;
(5) the sectional area of the formed graph is obtained, and the sectional area is measured by adopting a CAD measurement function;
(6) if the cross-sectional area of the drawing and SSqueeze and flattenWith deviation, the distance l1 is changed by adopting a minimum bisection method to obtain the sectional area and the SSqueeze and flattenAn equal cross-sectional view;
(7) obtaining 24 groups of flattened section views with different flattening rates by the method;
(8) the cross-sectional view is measured to obtain 24 sets of arc angles gamma.
In one embodiment, the flattening ratio may be from 24 setsAnd (3) taking 24 groups of arc angles as dependent variables, and obtaining a polynomial y-35297 x by adopting an Excel interpolation chart and a multi-surface fitting function4-24587x3+6633x2-861.35x + 175.23. After the fitting polynomial is determined, the polynomial can be directly input during electromagnetic calculation, and the arc angles of the wires under different flattening rates can be obtained.
Further, the width of the conductor after being flattened can be solved by mathematical geometry, as shown in fig. 3, according to the cosine theorem of triangle, the arc radius of the conductor after being flattened is solved
From the triangular sine theorem, l ═ r-r × sin ((180- γ)/2) is obtained, and the wire width b ═ b' +2 × l after the flattening is obtained. Solving to obtain the sectional area S of the flattened wireSqueeze and flatten＝a×b'+2×S2Wherein S is2＝SFlat shape-S1(ii) a Wherein, according to the sector area calculation formula, the method obtains
According to the triangle area calculation formula
