Description
Technical field
The utility model relates to winding mould technical field more particularly to a kind of distribution transformer oblong coil it is adjustable around
Line mold.
Background technique
Coil is the heart of transformer, and transformer is at runtime when line failure or lightening strikes generation atmosphere are excessively electric
When the movement of breaker generates switching impulse wave in pressure and route, coil will withstand greater than many instantaneous mistakes of rated operational voltage
Voltage.Oblong coil also known as racetrack-type rotor coil are exactly as its name suggests by circular coil dimidiation, centre increases one section
Straight line portion, similar to run-track shaped in sports ground, so gain the name.Compared to traditional circular coil transformer, using length
After circular coil, away from can accordingly reduce, the window width of iron core narrows at the center of transformer, high in identical core section product, iron core window
In the case where, the size of transformer in the longitudinal direction is more compact, and it is less using silicon steel sheet, it is identical in silicon steel sheet iron-loss per unit weight
In the case where, the no-load loss of transformer entirety is also minimized.Therefore, every electrical meeting in a certain sense
Under the premise of runnability, distribution transformer had not only saved material but also energy saving using oblong coil, thus had obtained numerous transformer systems
Make the favor and popularization of producer.
Currently, the coiling of oblong coil is mainly carried out on coil winding machine using fixed mold, due to transformation in the market
Type number is more, and oblong wire gauge is not of uniform size, needs to prepare the more winding mould being adapted with transformer model
To meet production requirement.Disadvantage is: raw material resources waste is big, and parking space occupancy is more, and production cost is higher, and use is not square
Just, working efficiency is lower.
Utility model content
To solve the problems mentioned above in the background art, the utility model provides a kind of length in coiling different size
Circular arc size and long axis direction adjustable winding mould can be realized when circular coil.
To achieve the above object, the utility model provides the following technical solutions: a kind of distribution transformer oblong coil can
Winding mould, including square axle sleeve are adjusted, the upper and lower surface of the square axle sleeve is symmetrically arranged with multiple long axis adjustment devices, described
The top of long axis adjustment device is provided with support plate, is equipped with hydraulic cylinder in the support plate, along the hydraulic cylinder axial direction
Semicircle is provided with several hydraulic pressure support bars.
Preferably, the long axis adjustment device includes two counterscrews and adjusting nut, and the adjusting nut setting exists
It links together among two counterscrews and by two counterscrews.
Preferably, the hydraulic cylinder is the semicircle hydraulic cylinder converted using hydraulic lifting principle.
Preferably, the hydraulic pressure support bar is T-shape telescopic rod, and the upper surface of " T-type " telescopic rod is equipped with radian, and
And it is remained on same arc surface in several hydraulic pressure support bar telescopic process.
The beneficial effects of the utility model are:
It is long to realize oblong coil by using the mating connection of adjusting nut and two counterscrews for the utility model
The adjusting of axis direction；Semicircle hydraulic cylinder is repacked by using hydraulic lifting principle, in the axial direction arrangement of semicircle hydraulic cylinder
Several telescopic hydraulic pressure support bars realize the adjusting of oblong coil circular arc size.The design of the utility model structure is skilful
It is wonderful, it is simple and practical, it is easily operated, production raw material and parking space are saved, production cost is reduced, improves work effect
Rate.
Detailed description of the invention
Fig. 1 is oblong coil adjustable winding lamps structure schematic diagram provided by the utility model.
Fig. 2 is that oblong coil adjustable winding provided by the utility model has side structure schematic diagram.
In figure: 1, square axle sleeve；2, long axis adjustment device；3, support plate；4, hydraulic cylinder；5, hydraulic pressure support bar；21, reversed
Screw rod；22, adjusting nut.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig.1 shown in -2, a kind of distribution transformer oblong coil adjustable winding tool provided by the utility model, packet
Square axle sleeve 1 is included, the upper and lower surface of square axle sleeve 1 is symmetrically arranged with multiple long axis adjustment devices 2, the top of long axis adjustment device 2
End is provided with support plate 3, and hydraulic cylinder 4 is equipped in support plate 3, is provided with along the 4 axial direction semicircle of hydraulic cylinder several
A hydraulic pressure support bar 5.
By using above-mentioned technical proposal, the utility model is by adjusting the long axis that 1 upper and lower surface of square axle sleeve is arranged in
The adjusting of straight length on oblong coil long axis direction may be implemented in regulating device 2；Hydraulic pressure support is controlled by hydraulic cylinder 4
Stretching for bar 5, may be implemented the adjusting of oblong coil circular arc size.The utility model can be raw according to the difference of transformer specification
The different oblong wire gauge of output, it is adaptable wide, it is easy to operate, the characteristics of high production efficiency.
Based on the above embodiment, the long axis adjustment device of the utility model includes two counterscrews 21 and adjusting nut 22,
The setting of adjusting nut 22 links together among two counterscrews 21 and by two counterscrews 21.It is reversed due to using
The special construction of screw rod, when rotating clockwise adjusting nut 22, the distance of two counterscrews 21 is gradually distance from, and makes mold two
The linear distance at end is elongated；When rotating counterclockwise adjusting nut 22, the distance of two counterscrews 21 is moved closer to, and makes mold
The linear distance at both ends shortens；Therefore the length of its long axis direction can be easily realized in the winding process of oblong coil
Degree is adjusted.
Based on the above embodiment, according to the technique for coiling feature of oblong coil, using hydraulic lifting principle by hydraulic cylinder 4
It is designed as semicircular structure.
Based on the above embodiment, hydraulic pressure support bar 5 is designed as T-shape telescopic rod, and the upper surface of " T-type " telescopic rod is equipped with arc
Degree, and remained on same arc surface in several 5 telescopic process of hydraulic pressure support bar.This structure can guarantee to grow
The circular arc degree of circular coil, to improve coiling quality.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
