Description
Technical field
This utility model is related to transformer technology field, and in particular to a kind of foil type winding transformer.
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.Foil type winding transformer refers to that winding is Copper Foil or aluminium foil
Transformator.Because the electric current of low pressure winding is generally larger, if using copper wire winding winding, many copper cash parallel connections are needed.In coiling
When if very big helical angle can be produced using laminar winding, when transformator is short-circuited, in the vertical direction of winding
Very big mechanical force can be produced, causes the damage of winding.And the end of Copper Foil or aluminium foil is flat, therefore which is suffered in short circuit
Axial force be copper cash winding construction part.Therefore, which has higher anti-short circuit capability.
For foil type winding transformer, need to be attached by connector between winding.As shown in figure 1, with two
As a example by individual aluminium foil winding, each winding 1 connects leaded aluminum row 2, and the lead aluminum of two windings is arranged 2 and one by securing member 3
Individual connector 4 is mechanically connected to outside transformator, and the shared connector 4 that connects through between two windings 1 is realized.The connection
Complex structure, needs to expend substantial amounts of human and material resources, and junction has hot-spot and burns hidden danger.Meanwhile, the connection is tied
Structure takes up space excessive, causes installing space narrow and small.
Chinese utility model patent《Foil winding pin configuration》(publication number：202796361U；Publication date：In March, 2013
13 days) in disclose a kind of Foil winding pin configuration, including winding conductor is the lead and pin configuration of foil.Described
Lead includes conductive foil and layer insulation, three groups of lead rows and three groups of outer lead rows, and described lead row is straight
Lead is arranged, and described outer lead row is bending outer lead row, the bottom of the straight lead row and the bottom of outer lead row
It is close to fix with described conductive foil.From analysis, the lead used by the structure can cause installing space narrow and small.
Chinese invention patent《Difference common mode Integral electronic transformator》(publication number：103646764A；Publication date：2014 3
Months 19 days) in disclose a kind of poor common mode Integral electronic transformator, the transformator include the first common mode inductance coiling bag, second
Common mode inductance coiling bag, the coupling assembly that the first common mode inductance coiling bag and the second common mode inductance coiling bag are coupled together.Institute
Stating coupling assembly includes the first coupling assembly and the second coupling assembly.First coupling assembly includes being arranged on described first altogether
The first fastener auxiliary section of first fastener at end and lower end is wrapped in mould inductance coiling.Second coupling assembly includes being arranged on institute
State the second common mode inductance coiling and wrap second fastener at end and the second fastener auxiliary section of lower end.First fastener and described
Two fasteners are respectively snap fit, and the first fastener auxiliary section and the second fastener auxiliary section are respectively draw-in groove；Wherein described first altogether
Mould inductance coiling bag and the second common mode inductance coiling bag realize connection by the docking of the snap fit and the draw-in groove.By institute
State structure to understand, the connecting component structure for connecting the first common mode inductance coiling bag and the second common mode inductance coiling bag is complicated, is difficult
Manufacture.
Generally speaking, existing foil type winding transformer, needs to be attached by connector between its winding.Cause to become
Depressor installing space is narrow and small, and winding junction has hot-spot and burns hidden danger.
