The optimization of production cost increases competitive advantage.Traditional low-voltage coil paper tinsel is pressed from both sides using irony more around the device body of distribution transformer
Part, but problems be present in irony folder：
1st, the low-voltage coil paper tinsel of 10kV distribution transformers uses iron clamp part around distribution transforming device body, and the outlet of low-voltage copper bar mainly has
Two kinds of structures：On the inside of folder and on the outside of folder.If low-voltage copper bar outlet on the outside of folder, the increase of device body overall width, transformation is caused
Device fuel tank is widened, transformer oil usage amount increase, low-voltage copper bar be both needed to carry out bending, waste the production time, add into production into
This；If transformer is from outlet on the inside of folder, so as to solve the problems, such as that outlet is present on the outside of folder.But because iron core folder uses
Irony folder, so as to there is certain ring current on irony folder, stray loss of transformer is caused to increase, so as to cause material
Expect cost increase；
2nd, the whole line of overall pressing plates is used for increase transformer anti-short circuit capability, traditional transformer body
Circle, to prevent coil short from deforming.
3rd, also need to add clamp insulation between iron core and folder.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model, which provides one kind, can save production cost, reduce energy and disappear
The 10kV distribution transformers of consumption wood clamp part and the distribution transformer using the wood clamp part.
To achieve the above object, the technical solution of the utility model is：
A kind of 10kV distribution transformers wood clamp part, the wood clamp part are separately positioned on iron core front and rear sides, against iron core,
And it is overlaid on the upper surface of coil；The wood clamp part is provided with the fluting of insertion wood clamp part, described to slot for making copper bar exposed
Go out wood clamp part.
Preferably, the wood clamp part is provided with least one vertical groove I against the side of iron core, groove I is from wood
The bottom of folder is penetrated to the top of wood clamp part, can either block the peripheral passage that can also turn into transformer oil with iron core, beneficial to change
Depressor oil circulation cooling.
Preferably, the bottom surface of the wood clamp part is provided with least one horizontal groove II, the groove II from wood clamp part
Penetrated against the side of iron core to another side, be easy to transformer oil circulation cooling.
Preferably, the left and right ends of the wood clamp part are provided with the neck for being used for connecting other pressing plate.
A kind of distribution transformer using 10kV distribution transformers wood clamp part described above, the distribution transformer,
Including the coil wound on housing, iron core, iron core, the upper surface of coil has covered wood clamp part, and wood clamp part is separately positioned on iron core
Front and rear sides, against iron core.
Preferably, the distribution transformer housing, which is provided with, draws screw rod, for wood clamp part and lower case to be fastened.
Preferably, the left and right ends of the wood clamp part are connected with other pressing plate, for covering outermost lateral coil.
Preferably, the bottom surface of the other pressing plate is provided with least one groove III, the groove III abuts from other pressing plate
The side of iron core is penetrated to another side, is easy to transformer oil circulation cooling.
Preferably, the wood clamp part of the iron core front and rear sides is connected using the steel drawstring of 2.0 steel plate bendings, to realize
Iron core top tenses.
Compared with prior art, it is the advantages of the utility model with beneficial effect：
By setting the wood clamp part against iron core on coil, wood clamp part directly bears against coil upper end face, saves device body pressure
Plate, it is more preferable to compress effect compared to device body pressing plate；Wood clamp part abuts iron core, saves traditional iron core clamp insulation；Wooden folder comes
Instead of irony folder, stray loss of transformer is reduced；The fluting of insertion wood clamp part is set on wood clamp part, makes low-voltage copper bar need not
Bending, directly expose from fluting, save process.
