Description
Technical field
The utility model relates to a kind of transformer outlet copper bar, relates in particular to a kind of outlet copper bar of transformer low voltage winding, belongs to transformer technology field.
Background technology
In the manufacturing process of transformer, due to the problems of welded quality of outlet wire of low voltage winding copper bar, cause the three-phase imbalance of low resistance, the situation that causes product not dispatch from the factory is more; Operating transformer, because the Welding Problems of outlet wire of low voltage winding copper bar causes quality accident also of common occurrence; Therefore, the stability of the welding quality control of outlet wire of low voltage winding copper bar, becomes a quality difficult problem that perplexs transformer production producer.
The traditional welding technique of transformer low voltage winding outlet copper bar is that Copper Foil is directly welded on outlet copper bar; again to dispel burr and add bag protection insulation processing of welding portion; prevent that solder joint, burr from making layer insulation impaired; as inadequate in operator's careful degree in coil winding process; just likely cause the safe operation accident of transformer, so the Welding Structure of traditional outlet copper bar and Copper Foil exists certain technique drawback.
Now also there is the design of offering a notch on transformer low voltage winding outlet copper bar, the design of notch, make the copper thickness of solder joint and welding lower than notch, after polishing, just there will not be interlayer due to the impaired accident causing of friction, but the notch complex structure of this kind of design, separately need offer chamfering; In addition, the shape of the welding ends of existing transformer low voltage winding outlet copper bar is generally traditional cuboid, and this kind of design exists the problem of taking material; Finally, existing transformer low voltage winding outlet copper bar is generally linear pattern, be prone to the phenomenon that copper bar two ends, outside exceed low pressure winding external diameter, and then in the time carrying out high pressure power frequency withstand test, there will be electric discharge phenomena, when serious, even there is the problem of insulation breakdown, cause transformer test defective, increased transformer and reprocessed operation.
Utility model content
Technical problem to be solved in the utility model is, a kind of transformer outlet copper bar with triangle welding notch is provided, this welding groove mouth structure is simple, offer easily, the thickness that makes the paper tinsel material after welding add solder joint is less than the degree of depth of weld notch, has avoided between the paper tinsel bed of material due to the impaired problem that causes accident that rubs; Further, welding ends of the present utility model is the design of oblique angle copper bar, in making outlet copper bar play identical action effect, has saved copper material, reduces production costs; Further, the setting of the crooked radian of welding ends of the present utility model, makes the same radian of welding ends and iron core, has avoided the generation of electric discharge phenomena etc., has greatly improved rate of finished products.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of transformer outlet copper bar, comprise: outlet copper bar, is characterized in that: described outlet copper bar comprises the terminals of one connection and for welding the welding ends of paper tinsel material, described welding ends is oblique angle copper bar, on described welding ends, be provided with welding notch, the cross section of described welding notch is triangular in shape.
The degree of depth of described welding notch is 3 ~ 5mm, the large 5 ~ 20mm of width of the more described paper tinsel material of length of described welding notch, and the angle of described welding notch is 100 ~ 150 °.
The thickness that described paper tinsel material after welding adds solder joint is less than the degree of depth of described welding notch.
Described paper tinsel material is drawn together Copper Foil.
Described welding ends has inside crooked radian.
Described crooked radian is concentric with iron core.
A kind of transformer outlet copper bar that the utility model provides, the setting of welding notch, the thickness that makes the paper tinsel material after welding add solder joint is less than the degree of depth of welding notch, avoid between the paper tinsel bed of material due to the impaired problem that causes accident of friction, the leg-of-mutton setting that is shaped as of welding notch, makes to weld notch and offers easily, and the angle of welding notch is the setting of 100 ~ 150 °, make to weld notch with occur that the junction of copper bar is lower, be convenient to Copper Foil rise around and without again offering chamfering; The setting of oblique angle copper bar has been saved copper material in making outlet copper bar play identical action effect, has reduced production cost; The setting of the crooked radian of welding ends, make the same radian of welding ends and iron core, avoided the generation of electric discharge phenomena etc., greatly improved rate of finished products.A kind of transformer outlet copper bar that the utility model provides, simple in structure, welding notch is offered easily, impaired without friction between copper foil layer, economizes in raw materials, and rate of finished products is high, is applicable to wide popularization and application.
