Description
Technical field
The utility model is related to field transformer, especially a kind of three dimensional wound core inside transformer pulling plate mounting structure.
Background technology
Currently, the safe operation of transformer is the important leverage of electric power netting safe running, and transformer anti-short circuit capability is it
One of most important guarantee of safe operation, traditional three dimensional wound core product, since design feature is mostly to draw screw rod or drawing screw rod
With pulling plate mixing tightening structure, the tightening force of these structures is limited, with the continuous increase of transformer capacity, the short circuit of transformer
Power is bigger, and traditional tightening structure can not meet the requirement of mechanical force, constrains the development of product for a long time, preferably to solve this
A little problems make the advantage of product further be promoted, the three dimensional wound core transformer pulling plate installation knot for requiring study novel
Structure.
Utility model content
The utility model is intended to solve one of above-mentioned technical problem in the related technology at least to a certain extent.For this purpose,
The utility model proposes a kind of saving material and transformer anti-short circuit capability can be improved, while three dimensional wound core simple in structure becomes
Depressor pulling plate mounting structure.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of three dimensional wound core transformer pulling plate mounting structure, including three dimensional wound core, upper and lower frame and it is set to institute
State the pulling plate between upper and lower frame；Be provided with centre bore on the stem of the three dimensional wound core, the pulling plate be plugged in it is described in
In heart hole, the upper and lower frame is connected and fixed with pulling plate upper and lower ends portion respectively；In above structure, by pulling plate insulating bag
It wraps up in and is mounted on iron core column center, around the coil uniform force on stem；Meanwhile without considering insulation of the coil to pulling plate
Distance, it is cost-effective to reduce device body product；In addition, relative to traditional drawing screw rod being arranged outside iron core column or
It draws screw rod and pulling plate mixing tightening structure, lead to lack many point of discharges over the ground, greatly simplifies lead arrangement, passed with using
The identical structure transformer of system structural upright rewinding material, which compares, can shorten wire length 10-30%, while reduce because lead passes through
And the insulating space retained, it further decreases transformer overall dimension and reduces transformer cost.
As an improvement of the above technical solution, the positioning for three dimensional wound core placement positioning is provided on the lower frame
Portion, the positioning region correspond to the central hole location and are provided with locating slot for pulling plate installation positioning.
As a further improvement of the above technical scheme, there are many dimensions settings of the pulling plate, pulling plate length is set
Set it is different to generate pressing force to coil also different, meanwhile, analysis pulling plate stress determines its sectional dimension specification, on the stem in
The size corresponding matching of heart pore size and the pulling plate.
Further, the pulling plate outer surface is provided with insulating layer.
Further, pulling plate upper and lower ends portion is both provided with connecting hole, and the upper and lower frame corresponding position is provided with peace
Hole is filled, is connected and fixed pulling plate and the upper and lower frame by axis pin.
The utility model has the beneficial effects that：A kind of three dimensional wound core transformer pulling plate mounting structure of the utility model,
Including three dimensional wound core, upper and lower frame and the pulling plate being set between the upper and lower frame；The stem of the three dimensional wound core
On be provided with centre bore, the pulling plate is plugged in the centre bore, the upper and lower frame respectively with the pulling plate upper and lower ends
Portion is connected and fixed；In above structure, pulling plate is at iron core column center, around the coil uniform force on stem；Meanwhile it being not necessarily to
Consider that coil to the insulation distance of pulling plate, accumulates to reduce device body, it is cost-effective；In addition, relative to traditional in the iron core heart
The drawing screw rod or drawing screw rod and pulling plate mixing tightening structure being arranged outside column, lead have lacked many point of discharges over the ground, greatly letter
Change lead arrangement, can shorten wire length 10- compared with using the identical structure transformer of traditional structure three dimensional wound core
30%, at the same reduce because lead by by the insulating space that retains, further decrease transformer overall dimension and reduce and become
Depressor cost.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model mounting structure schematic diagram；
Fig. 2 is pulling plate installation sectional view.
Specific implementation mode
Referring to figs. 1 to Fig. 2, a kind of three dimensional wound core transformer pulling plate mounting structure of the utility model, including three-dimensional winding
