Description
Technical field
This technology belongs to reactor winding technique field, is related to a kind of multilayer mixed winding reactor.
Background technology
When reactance switch transfers the files bridge joint, magnetic flux, iron are generated in iron core for the iron core reactor of for transformer reactance pressure regulation
Core reactor can hinder the increase of circulating current under the action of inductance, when reactance switch transfers the files unbridged, without magnetic in iron core
Logical, reactor winding becomes noninductive coil, at this point, two winding coupleds of iron core reactor are good, therefore, it is necessary to require reactance
The number of turn of two windings of device iron core, around to should be identical with size, the needs of transformer normal operation could be met.
In the prior art, two windings of iron core reactor are independent coilings respectively, therefore, the radial dimension of winding, around
The height of system can be there are certain deviation, and the D.C. resistance for leading to two windings is unequal, and coupling is poor, when reactance switchs
When transferring the files unbridged, magnetic flux cannot be completely counterbalanced by iron core, and circulating current can be generated between two windings, and transformer is being run
In there are security risks.
Invention content
The purpose of this utility model is to provide a kind of multilayer mixed winding reactor, solves in the prior art, there are reactance
The arrangement of two winding conducting wires of device is uneven, and length is variant, causes coupling poor, and there are security risks during transformer station high-voltage side bus
Problem.
The technical solution of the utility model：Multilayer mixed winding reactor, on the Insulated winding wire mould of the reactor uniformly around
Electrical winding is formed with, is hollow cylindrical in winding former, is set with collets in the upper and lower ends of winding former, electrical winding is by two
The insulated conductor of root parallel side-by-side is formed simultaneously from the uniform coiling of internal layer to outer layer, and two groups of parallel side-by-sides are formed after sandwich wound
The end of a thread of electrical winding, two groups of electrical winding inlet wires and outlet stays in reactor upper end, the coiling of one of electrical winding
Beginning A, coiling terminal C, the coiling beginning D of another electrical winding, coiling terminal B.
It is designed with dielectric separation plate on the interlude of winding former, electrical winding is wound on up and down the two of demarcation strip respectively
End forms two sections electrical winding, is respectively communicated between two sections electrical winding, and insulated conductor introduces above epimere,
Coiling introduces hypomere internal layer, hypomere from internal layer coiling to outer layer, complete by coiling to outer layer after the completion of epimere coiling since internal layer
Afterwards reactor upper end is led back from outer layer.
Using the technical program, it is due to the conducting wire of two windings of reactor while is wound on coiling layer by layer in the same direction side by side
On mould, it can be ensured that coil turn, the winding length of two windings are identical with direction, and the size of conducting wire and material are homogeneous
Together, so that it is guaranteed that the D.C. resistance of two windings is identical, ensure that two windings can be coupled highly.When reactance switch transfers the files bridge joint simultaneously
During connection, coiling beginning A and coiling terminal C is connected as incoming end, and coiling beginning D and coiling terminal B are connected as picking out end, two electricity
Gas winding forms parallel connection, and magnetic flux is generated in iron core, under the inductance effect of iron core reactor, can effectively hinder the increasing of circulating current
Greatly, when reactance switch transfer the files unbridged series connection when, coiling beginning A is connect with coiling terminal C, coiling beginning D be incoming end, coiling
Terminal B forms series connection to pick out end, two electrical windings, and magnetic flux is completely counterbalanced by iron core, and reactor winding becomes noninductive coil,
At this point, two winding heights coupling of iron core reactor.
Further, since at the both ends of winding former and the intermediate end collets and layer insulation for being respectively arranged with activity installation
Block, the coiling segmentation of winding is wound between end collets and layer insulation block, so that it is guaranteed that coiling can closely coiling layer by layer
On winding former, ensure the coiling coiling arranged side by side everywhere of two windings, so that it is guaranteed that the physical attribute of two windings is identical.
In conclusion no matter two windings of reactor are series connection also parallel connection, winding can ensure transformer to greatest extent
Operational safety.
