Description
Technical field
The pin configuration of the invention relates to a kind of 3-D triangle transformer that is applicable to, the pin configuration when low-voltage lead y connects helps arranging and the balance of D.C. resistance of low-voltage lead.
Background technology
The low-voltage lead mode of 3-D triangle transformer is subjected to the influence of transformer device structure form, and b phase winding lead-in wire is longer, causes the D.C. resistance imbalance easily.
At present, the low-voltage lead structure multiple-effect of 3-D triangle transformer is imitated flat surface transformer, the copper bar that will go between is fixed on the folder outside, draw along folder, because the particularity of 3-D triangle transformer device structure, cause the b phase terminal longer, make resistance balance, cause the waste of copper bar by the sectional area that increases b phase copper bar; Comparatively Xian Jin mode is the zero sequence copper bar with three phase windings, strides across folder and guides to the transformer top, and draw from mid point, helps the D.C. resistance balance of three phase windings, but has increased device height degree, and aesthetic property is poor.
Mainly there is following problem in the low-voltage lead structure that is used for the 3-D triangle transformer at present: long b row mutually can cause the D.C. resistance imbalance; Irrational lead-in wire mode can cause the waste of copper material and device height degree to increase.
Summary of the invention
The objective of the invention is to: at present 3-D triangle transformer low voltage pin configuration, the improvement that rationalizes reaches each phase resistance balance with simple way, the succinct purpose attractive in appearance of profile.
Technical scheme of the present invention is: a kind of low-voltage lead structure that is applicable to the 3-D triangle transformer, it comprises that the low pressure winding is started, a low pressure winding end copper bar, triangle flat plate folder, and it is characterized in that: the low pressure winding is started and is fixed on the outside of triangle flat plate folder; A winding end copper bar is fixed on the inboard of triangle flat plate folder, and forms the intersection mid point by copper bar central point fixed insulation; The b copper bar of starting mutually causes start mutually copper bar and c of a along the triangle flat plate folder and starts mutually in the middle of the copper bar.
The above-mentioned low-voltage lead structure that is used for the 3-D triangle transformer, it is further characterized in that: the outside that start (a, b, the c) of low pressure winding is fixed on the triangle flat plate folder; The end head (x, y, z) of low pressure winding is fixed on the inboard of triangle flat plate folder; Utilize the space between triangularity depressor volume iron core bight, folder and the coil, low pressure winding end head (x, y, z) is linked to each other to form intersect mid point; Zero sequence is drawn the neutral point of copper bar and is drawn from the intersection midpoint.Pin configuration cooperates special triangle flat plate folder.
The invention has the advantages that: winding end head (x, y, z) is drawn in the folder inboard, is crossed as neutral point, has realized that the three-phase zero sequence is isometric, solves the unbalanced problem of D.C. resistance; Utilize the space between triangle volume iron core, folder and the winding, lead-in wire does not increase device height degree; Pin configuration is rationally simple, and manufacturing process realizes easily, good looking appearance, and the copper bar consumption is saved in the repetition of copper bar, overlapping when avoiding going between.。
Description of drawings
