Description
Technical field
This utility model is related to transformer technology field, and in particular to a kind of Transformer Winding goes out wire-connecting device.
Background technology
Transformator is changing the device of alternating voltage using the principle of electromagnetic induction.Due to transformator itself performance with
Feature so that the development of transformator is closely bound up with power grid construction.For transformator, its winding needs to connect with external circuit
Connecing can just carry out the conversion of voltage, electric current and impedance.Therefore, for Transformer Winding draw go out wire-connecting device meet the tendency of and
It is raw.
Traditional transformator using winding formed by Copper Foil coiling.The winding is to pass through with the connection of external circuit
What the copper bar being connected with Copper Foil was realized.Generally, copper bar is directly welded on copper foil surface.But due to the cost of copper it is big,
It is unfavorable for production, Copper Foil is gradually replaced by the excellent aluminium foil of cost performance.For example, the high power UPS on market
(UPS) the contravariant transformer almost all used in is changed to aluminium foil coiling by previous Copper Foil.Moreover, rail transport,
Numerous power electronics industries such as new forms of energy are very universal using aluminium foil coiling transformator, reactor.Due to aluminum foil transformer
In coiling winding, the aluminium foil which is located at winding terminal is domestic with the welding of copper bar mostly using traditional argon arc welding.But argon
Arc-welding is very high to the proficiency dependency of operator, weld interval length, produce radioactive substance thorium and harmful gass ozone and
Nitrogen oxides affect health.In addition, aluminium foil can also be using copper aluminum row as welding carrier with during welding copper bus.But copper aluminum
Arrange one end by copper bar by it is tin plating arrange one end with aluminum and weld formed, its weldability is poor, and then to the generation of integrally-built performance
Adverse effect.
Chinese invention patent《A kind of welding method of Transformer Winding aluminium foil and copper bar》(publication number：101829855A；It is public
Open day：On September 15th, 2010) in disclose the welding method of a kind of Transformer Winding aluminium foil and copper bar, the method is to adopt copper
Copper Foil is first welded with copper bar, then Copper Foil is welded with aluminium foil as aluminium foil and the welding carrier of copper bar by paper tinsel.It is described
The welding method of Copper Foil and copper bar be argon arc welding, welding current is 250-350A.It follows that lacking existing for the method
Point, argon arc welding is very high to the proficiency dependency of operator, weld interval length, produce radioactive substance thorium and harmful gass are smelly
Oxygen and nitrogen oxides affect health.In addition, Copper Foil and aluminium foil are due to material problem, weldability between the two is poor.Typically
It is the method using tining, Copper Foil is welded together with aluminium foil.But aluminum belongs to active metal, easily aoxidize, upper stannum is very tired
Difficulty, causes the weldability between Copper Foil and aluminium foil poor.
Therefore, for the transformator that winding is turned to by aluminium foil, need by the welding of aluminium foil and copper bar to realize
The connection of Transformer Winding and external circuit.But in prior art, aluminium foil there are problems that many with the welding of copper bar.For example,
Due to material problem between aluminum and copper product, weldability between the two is poor, causes transformator quality problems easily occur,
There is potential safety hazard.In addition, the method for welding can produce harmful gass for argon arc welding and affect health.
