Description
Technical field
The present invention relates to the transformer outlet copper bar that a kind of crooked radian is variable, particularly relate to the outlet copper bar that the crooked radian of a kind of transformer low voltage winding is variable, belong to transformer technology field.
Background technology
Current transformer low voltage winding outlet copper bar is generally the arc of curvature degree type that linear pattern or radian are fixing, easily there is the copper bar two ends, the outside phenomenon beyond low pressure winding external diameter in linear pattern, and then there will be electric discharge phenomena when carrying out the test of high pressure industrial frequency withstand voltage, problem time serious, insulation breakdown even occurring, cause transformer test defective, add transformer and reprocess operation；The arc of curvature degree type that radian is fixed may be only available for the iron core of fixed size, when changing the iron core without model, then needs to change the outlet copper bar of radian coupling therewith simultaneously, and i.e. outlet copper bar is without versatility.
During the manufacturing of transformer, due to the problems of welded quality of outlet wire of low voltage winding copper bar, causing the three-phase imbalance of low resistance, the situation causing product not dispatch from the factory is more；Operating transformer, causes quality accident the most of common occurrence due to the Welding Problems of outlet wire of low voltage winding copper bar；Therefore, the stability of the welding quality of outlet wire of low voltage winding copper bar controls, and becomes a quality difficult problem of puzzlement transformer production producer.
The conventional bonding technique of transformer low voltage winding outlet copper bar is to be directly welded on outlet copper bar by Copper Foil; again welding portion is dispelled burr and add bag protection insulation processing; prevent solder joint, burr from making layer insulation impaired; as inadequate in operator's careful degree in coil-winding process; it is possible to cause the safe operation accident of transformer, so the Welding Structure of traditional outlet copper bar and Copper Foil exists certain technique drawback.
Also occur in that the design offering a notch on transformer low voltage winding outlet copper bar now, the design of notch, make the copper thickness of solder joint and welding less than notch, interlayer would not occur after polishing due to the impaired accident caused that rubs, but the notch arrangement of this kind of design is complicated, separately need to offer chamfering.
Summary of the invention
The technical problem to be solved is to provide the transformer outlet copper bar that a kind of crooked radian is variable, and the crooked radian of outlet copper bar changes along with the change of the radian of the iron core selected, and has versatility；Further, the setting of the crooked radian of the welding ends of the present invention, make welding ends and the same radian of iron core, it is to avoid the generation of electric discharge phenomena etc., substantially increase yield rate；Further, the setting of triangle welding notch, make the paper tinsel material after welding add the thickness of the solder joint degree of depth less than welding notch, it is to avoid due to the impaired problem causing accident that rubs between the paper tinsel bed of material, and to weld notch design simple in construction, offer easily.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
The transformer outlet copper bar that a kind of crooked radian is variable, including: outlet copper bar, it is characterized in that: described outlet copper bar includes the terminals integrally connected and for welding the welding ends of paper tinsel material, described welding ends includes the canned paragraph being positioned at two ends and is positioned at the bending section of centre, described bending section has inside crooked radian, and described crooked radian changes along with the change of the radian of the iron core selected.
Described bending section is flexible coupling by some copper foils and forms, and after some described copper foil overlaps, two ends are fixed by described canned paragraph.
Described canned paragraph is provided with the groove for accommodating some copper foil two ends, and the two ends of copper foil are fixed with pressing machine pressing after stretching into groove.
The length of described canned paragraph accounts for the 1/5 ~ 1/10 of the length of described welding ends.
The number of plies of described copper foil is at least 10 layers, and the length of described copper foil is the most progressively longer, and the length difference of adjacent described copper foil is 4 ~ 20mm.
Being provided with welding notch on described canned paragraph, the cross section of described welding notch is triangular in shape.
The degree of depth of described welding notch is 3 ~ 5mm, and the big 5 ~ 20mm of width of the length more described paper tinsel material of described welding notch, the angle of described welding notch is 100 ~ 150 °.
Described paper tinsel material after welding adds the thickness degree of depth less than described welding notch of solder joint.
Described paper tinsel material includes Copper Foil.
The variable transformer outlet copper bar of a kind of crooked radian that the present invention provides, bending section has inside crooked radian, the design of crooked radian variable (i.e. the crooked radian of bending section changes along with the change of the radian of the iron core selected), outlet copper bar versatility is made to strengthen, and tightr with the laminating degree of iron core；The setting of welding notch, the paper tinsel material after welding is made to add the thickness degree of depth less than welding notch of solder joint, avoid between the paper tinsel bed of material due to the impaired problem causing accident that rubs, the setting being shaped as triangle of welding notch, welding notch is made to offer easily, welding notch the setting that angle is 100 ~ 150 °, it is relatively low with junction copper bar occur to make welding notch, it is simple to Copper Foil rise around and without again offering chamfering；The setting of the crooked radian of welding ends, make welding ends and the same radian of iron core, it is to avoid the generation of electric discharge phenomena etc., substantially increases yield rate.The variable transformer outlet copper bar of a kind of crooked radian that the present invention provides, simple in construction, outlet copper bar crooked radian is variable, and welding notch is offered easily, and Copper Foil interlayer is impaired without friction, and yield rate is high, applicable wide popularization and application.
