Description
Technical field
The present invention relates to a kind of winding, relate to a kind of aerogenerator stator winding and winding method thereof particularly.
Background technology
The stator winding of existing motor has the distributed winding of employing, also has and adopts centralized winding.See Fig. 1, for centralized winding, for ease of the multiple series-parallel system between winding, be all generally that concentratred winding shaping for coiling is assembled on a teeth groove of stator core, and then each concentratred winding is carried out wiring, obtain multi phase stator winding.For the stator of large-scale, that the number of teeth is more wind-driven generator, if employing concentratred winding, wiring after the assembling of winding and rule is obviously very complicated, and the stator winding therefore, a kind ofly reduce rule workload, reducing wiring becomes the target that those skilled in the art pursue.
Summary of the invention
The object of the invention is to solve the technical problem that the rule of the centralized winding of existing aerogenerator stator, wiring are numerous and diverse.
Technical scheme of the present invention is: a kind of aerogenerator stator winding, described winding is centralized winding, it is characterized in that: it comprises a coiling and forms and two and half windings in the be located at adjacent stators teeth groove be connected as a single entity: the first half windings and the second half windings, one end of described two and half windings is connected.
As preferably, two and half described windings around to identical, the end of two and half windings is connected; Or, described the first half windings and the second half windings around on the contrary, the end of described the first half windings is connected with the head end of the second half windings.
It should be noted that the head end of winding of the present invention refers to: one end of input current, end refers to one end of output current.
The winding method of aerogenerator stator winding of the present invention is: this winding carries out coiling on a straight line rod mould, and the two ends of this straight line rod mould have same shape and diameter, have one section of changeover portion in the middle of it; Winding method is: first turned on one end of straight line rod mould by the first half windings, stride across middle reserved changeover portion again the second half windings are continued to turn on this straight line rod mould ground other end, then, from the centre position of the first half windings and the second half windings by the second half winding upsets, obtain two half windings be connected as a single entity.
As preferably, the second half windings are turned over turnback, obtain half winding of the coiling in the same way that two are connected as a single entity by described the first half windings and the second half winding coilings in a direction to the inside.Adopt this method coiling, its advantage is: two and half windings around to identical, the end simultaneously overturning two and half windings obtained is connected, and the cable run distance like this between two adjacent two teeth is short.Or the second half windings are turned over turnback, obtain half winding of the reverse coiling that two are connected as a single entity by described the first half windings and the second half reverse coilings of winding to the inside.
Aerogenerator stator winding of the present invention, because each concentratred winding is made up of two half windings be connected as a single entity, when rule, can disposable two and half windings be embedded on two adjacent teeth groove, and this two and half winding only has two terminals, therefore, half terminals can be reduced for stator, therefore, can significantly reduce wiring work, simplify mounting process, improve installation effectiveness.Simultaneously because terminals reduce, pad reduces, and corresponding failure point can reduce, and reliability is improved.
Further, aerogenerator stator winding of the present invention, wherein two and half windings adopt coiling in the same way, and both ends are connected, its advantage is, during coiling can on a winding mould once complete two and half windings of coiling in the same way, then, overturn from the centre position of winding, thus obtain two and half windings that two ends connect, coiling is identical.Therefore, it makes more simple, convenient.
Aerogenerator stator winding of the present invention can form by the disposable coiling of one set of die, makes simple.Particularly further by the coiling in the same way of two and half windings, turn over half winding that turnback can obtain two coilings in the same way, the method for its coiling is more easy.And two and half winding be that end is connected, make the cable run distance between two teeth the shortest.
