Abstract
The invention discloses a kind of novel screw type coil, including winding wire, the winding wire is formed by coil head end and coil end coiling, and the cross-over block that the winding wire vertical direction is provided with support winding wire forms axial oil duct.The present invention carries out the oppositely wound coil head end that arrives of liter layer when continuous coiling on winding former is to coil end and cancels coil axial direction oil duct, reduces coil height, improves the filling rate of coil；Winding protruding head is arranged in coil head end the same side simultaneously, facilitates lead to arrange.
Description
Technical field
The present invention relates to transformer technology field, is specifically related to a kind of novel screw type coil.
Background technology
Current most of helical winding (including single-screw, double helix and more spirals) is the continuous coiling on winding former
Form, replaced therebetween according to different screw-types, coil first and last is lifted one's head places by exhausted between coil both ends, coil cake
The cross-over block that the punching of edge cardboard or milling form forms axial oil duct, so as to disperse coil in transformer station high-voltage side bus it is caused
Heat, make transformer temperature rise control in allowed limits.
The content of the invention
The present invention is intended to provide a kind of novel screw type coil.
The present invention provides following technical scheme：
A kind of novel screw type coil, including winding wire, the winding wire is by coil head end and coil end coiling
Form, the cross-over block that the winding wire vertical direction is provided with support winding wire forms axial oil duct.
The cross-over block is formed by insulating board punching or milling.
The cross-over block is fan-shaped cushion block.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention on winding former continuous coiling to coil end
Shi Jinhang rises the oppositely wound coil head end that arrives of layer and cancels coil axial direction oil duct, reduces coil height, improves the filling rate of coil；Together
When winding protruding head is arranged in coil head end the same side, facilitate lead to arrange.
Brief description of the drawings
Fig. 1 is the front view of the helical winding of the present invention；
Fig. 2 is the top view of the helical winding of the present invention.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
Obviously, described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based in the present invention
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of protection of the invention.
A kind of novel screw type coil of embodiment, including winding wire, the winding wire is by coil head end 1 and coil end
2 coilings are held to form, the cross-over block that the winding wire vertical direction is provided with support winding wire forms axial oil duct 3, institute
Cross-over block is stated to be formed by insulating board punching or milling.The cross-over block is fan-shaped cushion block.The present invention connects on winding former
Continuous coiling is oppositely wound to coil head end cancellation coil axial direction oil duct to liter layer is carried out during coil end, reduces coil height, carries
The filling rate of high coil；Winding protruding head is arranged in coil head end the same side simultaneously, facilitates lead to arrange.
It is obvious to a person skilled in the art that the invention is not restricted to the details of the one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than the explanation limits, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each
Embodiment only includes an independent technical scheme, and this narrating mode of specification is only this area for clarity
Technical staff should be using specification as an entirety, and the technical solutions in the various embodiments may also be suitably combined, forms this
The other embodiment that art personnel are appreciated that.
