Background technology
Traditional transformator three dimensional wound core mostly by three identical, be put together with the single frame unshakable in one's determination of stalloy continuous coiling, there is three-phase equilibrium, open circuit loss is low, no-load current is low, noise is low and low cost and other advantages.But the defect of such closed type three dimensional wound core structure is to be: manufacturing necessary first coiling iron-core during product, then coiling on stem, this makes production efficiency be difficult to be greatly improved；Simultaneously, along with three dimensional wound core technology is extensively applied on Large Copacity or voltage levels product, particularly 35kV or 110kV and above product, iron core or coil are all big than conventional stereo rewinding material product, if manufactured the most by this method, more, larger Special Equipment must be put into and could meet production requirement, invest huge, closed type three dimensional wound core technology is limited by the factor such as equipment or technique, can not be widely used on the product of Large Copacity or voltage levels, thus affect the development of three dimensional wound core.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of open type three dimensional wound core, unshakable in one's determination and coil can carry out coiling simultaneously, improve production efficiency, need not put into too many professional equipment during manufacture, lower cost of investment, effectively promote development and the application of three dimensional wound core technology.
This utility model solves the technical scheme that its technical problem is used:
A kind of open type three dimensional wound core, including more than one single frame unshakable in one's determination, described single frame unshakable in one's determination by silicon-steel sheet coiled around forming, described single frame unshakable in one's determination includes to be wound around the stem of coil, each described stem top is formed with upper yoke portion, and described upper yoke portion is provided with interface, and described upper yoke portion is provided with removable half frame, half described frame is arranged on the inner side in described upper yoke portion, and described interface is arranged on the outside in described upper yoke portion.
Further, the cross section of half described frame accounts for the 3/7 of single frame cross section unshakable in one's determination.
Further, described single frame unshakable in one's determination has 3.
Utility model provides the benefit that: the upper yoke portion of single frame unshakable in one's determination is provided with interface, can the upper yoke portion of the single frame unshakable in one's determination cut off be smoothed out with the fingers directly along stem by interface, it is easy to be inserted in around the coil made, make single frame unshakable in one's determination and coil can carry out coiling simultaneously, improve production efficiency, need not put into too many professional equipment during manufacture, lower cost of investment, effectively promote development and the application of three dimensional wound core technology.

Detailed description of the invention
With reference to Fig. 1 ~ 5, a kind of open type three dimensional wound core, including more than one single frame 1 unshakable in one's determination, single frame 1 unshakable in one's determination is by silicon-steel sheet coiled around forming, and single frame 1 unshakable in one's determination includes to be wound around the stem 11 of coil, and each described stem 11 top is formed with upper yoke portion 12, upper yoke portion 12 is provided with interface 121, upper yoke portion 12 is provided with removable half frame 122, and half frame 122 is arranged on the inner side in upper yoke portion 12, and interface 121 is arranged on the outside in described upper yoke portion 12.
A.
First stalloy is wound into continuously single frame 1(iron core single frame 1 inboard portion unshakable in one's determination of 3/7), B. the upper yoke portion 12 from single frame 1 inboard portion unshakable in one's determination isolates half frame 122, half frame 122 is put back into single frame 1 unshakable in one's determination again, the single frame the most unshakable in one's determination 1 (single frame 1 Outboard Sections unshakable in one's determination) of winding residue 4/7, during winding, upper yoke portion 12 at single frame 1 Outboard Sections unshakable in one's determination, technique sheet 2 placed by the stalloy of each layer, wind single frame 1 unshakable in one's determination, D. technique sheet 2 is extracted out, the upper yoke portion 12 of single frame 1 Outboard Sections unshakable in one's determination becomes soft, the stalloy being easy to the upper yoke portion 12 to single frame 1 Outboard Sections unshakable in one's determination cuts off, the successively stalloy on Cutting process sheet 2, form interface 121, E2. by mutual in 60 for 3 adjacent single frames 1 unshakable in one's determination。Carry out split, F. the upper yoke portion 12 of single frame unshakable in one's determination 1 Outboard Sections cut off is smoothed out with the fingers directly along stem 11, take out half frame 122, coil coiling completed is nested into two stems 11 of phase split, G. half frame 122 is put back into single frame 1 unshakable in one's determination, H. the upper yoke portion 12 smoothing out with the fingers straight single frame unshakable in one's determination 1 Outboard Sections is smoothed out with the fingers and put down go back to original position, interface 121 is sealed.
nullThe upper yoke portion 12 of single frame 1 Outboard Sections unshakable in one's determination is provided with interface 121，The upper yoke portion 12 of inboard portion is provided with removable half frame 122，Easily half frame 122 can be dismounted，Supporting role is also played by other half frame 122 in the upper yoke portion 12 of single frame 1 Outboard Sections unshakable in one's determination，Make structure more firm，The upper yoke portion 12 of single frame unshakable in one's determination 1 Outboard Sections cut off can be smoothed out with the fingers directly along stem 11 by interface 121 and removable half frame 122，It is easy to be inserted in around the coil made，Make single frame 1 unshakable in one's determination and coil can carry out coiling simultaneously，Have employed open type structure，Not only ensure the unique advantage of three dimensional wound core，Even if increase or the raising of electric pressure along with capacity，Particularly manufacture 35kV or 110kV and the product of above，Single frame 1 unshakable in one's determination and coil can also separate independent production，And the coil winding used、Compress and shaping device is the most as before，Need not again invest new equipment，So can improve the scope of application of three dimensional wound core technology，Reduce manufacturing cost.
Additionally, when opening the upper yoke portion 12 of single frame 1 Outboard Sections unshakable in one's determination, can first dismantle lower half frame 122, so can effectively reduce the bent angle of interface 121 turning stalloy, facilitate coil to be inserted on stem 11, be reinstalled half frame 122 and the interface 121 that closes after being set with, it is ensured that product operationally flow direction is consistent with stalloy direction, lower open circuit loss unshakable in one's determination and no-load current, give full play to the advantage of three dimensional wound core.
The above, better embodiment the most of the present utility model, but this utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
