Abstract
The utility model relates to a heavy-current copper bar dense combined structure for a transformer, and belongs to the technical field of transformers. The heavy-current copper bar dense combined structure solves the problem of poor low-voltage copper bar supporting angle steel intensity of the existing electric furnace transformer. The heavy-current copper bar dense combined structure comprises an upper bearing strip and a lower bearing strip, wherein the upper bearing strip is arranged on an upper bearing frame, the lower bearing strip is arranged on a lower bearing frame, an upper inserting groove is formed in the upper bearing strip, a lower inserting groove is formed in the lower bearing strip, a plurality of wire inlet copper bar groups and a plurality of wire outlet copper bar groups are arranged between the upper inserting groove and the lower inserting groove, each air inlet copper bar group comprises two wire inlet copper bars in parallel arrangement, each wire outlet copper bar group comprises two wire outlet copper bars in parallel arrangement, a first paperboard is arranged between the two wire inlet copper bars of each wire inlet copper bar group, and a second paperboard is arranged between two wire outlet copper bars of each wire outlet copper bar group. The heavy-current copper bar dense combined structure has the advantages that the low-voltage copper bar bearing intensity is high, the structure is simple, and the manufacturing cost is low.
Description
Technical field
The utility model belongs to transformer technology field, particularly a kind of export structure of furnace transformer.
Background technology
Furnace transformer is High-current output, when low voltage outlet terminals adopts 1 * 2 branch road or 1 * 3 branch road, and for guaranteeing that ampacity and the electric current kelvin effect of inner copper bar reduces, normal 2 * 2 branch roads or 2 * 3 branch roads of adopting of low-voltage copper bar that original structure inside is electrically connected with it.Although original structure has guaranteed the electric property of furnace transformer low-pressure side, increased the distance of low-voltage coil and transformer box wall, cause manufactured materials steel, transformer wet goods material to increase, cost rises; And copper bar supporting angle steel is because length lengthens, and bearing strength is inadequate, can cause that lead-in wire copper bar tilts, and causes connecting staggered.
Summary of the invention
Inadequate for solving existing electric furnace transformer copper bar supporting angle steel bearing strength, easily cause that lead-in wire copper bar tilt to sink, the problem of connecting staggered, the utility model provides the intensive combining structure of large current copper bar for a kind of transformer, and its technical scheme is as follows:
The intensive combining structure of large current copper bar for transformer, is arranged on the pressing plate for secured core, comprises the upper support frame and the lower supporting frame that are frame-like;
On upper support frame, be provided with two upper supporting strips that are parallel to each other;
Be positioned at upper supporting strip and vertically on the lower supporting frame of below, be provided with two lower support bars that are parallel to each other;
Upper supporting strip bottom is provided with the upper slot that several are counterbore shape;
Be positioned at slot and vertically on the lower support bar of below, be provided with the lower slot that several are counterbore shape;
Between upper slot and lower slot, be provided with some inlet wire copper bar groups and some outlet copper bar groups, inlet wire copper bar group and outlet copper bar group are alternately;
Each inlet wire copper bar group comprises two inlet wire copper bars that be arranged in parallel;
Each outlet copper bar group comprises two outlet copper bars that be arranged in parallel;
Between two inlet wire copper bars of each inlet wire copper bar group, be provided with the first cardboard;
Between two outlet copper bars of each outlet copper bar group, be provided with the second cardboard.
Preferably, the thickness of described the first cardboard and the second cardboard is 0.5 millimeter;
