Description
Technical field
The present invention relates to winding mould technical field more particularly to a kind of distribution transformer oblong coil adjustable windings
Tool.
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.
Summary of the invention
To solve the problems mentioned above in the background art, the present invention provides a kind of oblongs in coiling different size
Circular arc size and long axis direction adjustable winding mould can be realized when coil.
To achieve the above object, the invention provides the following technical scheme: a kind of distribution transformer oblong coil it is adjustable around
Line mold, including square axle sleeve, the upper and lower surface of the square axle sleeve are symmetrically arranged with multiple long axis adjustment devices, the long axis
The top of regulating device is provided with support plate, is equipped with hydraulic cylinder in the support plate, along the hydraulic cylinder axial direction semicircle
Shape 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 present invention are:
The present invention realizes oblong coil long axis side by using the mating connection of adjusting nut and two counterscrews
To adjusting；Semicircle hydraulic cylinder is repacked by using hydraulic lifting principle, it is several in the axial direction arrangement of semicircle hydraulic cylinder
A telescopic hydraulic pressure support bar realizes the adjusting of oblong coil circular arc size.Structure of the invention is ingenious in design, simple real
With, it is easily operated, production raw material and parking space are saved, production cost is reduced, improves work efficiency.
Detailed description of the invention
Fig. 1 is oblong coil adjustable winding lamps structure schematic diagram provided by the invention.
Fig. 2 is that oblong coil adjustable winding provided by the invention 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
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig.1 shown in -2, a kind of distribution transformer oblong coil adjustable winding tool provided by the invention, including side
Shape axle sleeve 1, the upper and lower surface of square axle sleeve 1 are symmetrically arranged with multiple long axis adjustment devices 2, and the top of long axis adjustment device 2 is set
It is equipped with support plate 3, hydraulic cylinder 4 is installed in support plate 3, the 4 axial direction semicircle of hydraulic cylinder is provided with several liquid
Press support rod 5.
By using above-mentioned technical proposal, the present invention is adjusted 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 device 2；Hydraulic pressure support bar 5 is controlled by hydraulic cylinder 4
It is flexible, the adjusting of oblong coil circular arc size may be implemented.The present invention can produce difference according to the difference of transformer specification
Oblong wire gauge, 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 present invention includes two counterscrews 21 and adjusting nut 22, is adjusted
The setting of nut 22 links together among two counterscrews 21 and by two counterscrews 21.Due to using counterscrew
Special construction, when rotating clockwise adjusting nut 22, the distance of two counterscrews 21 is gradually distance from, and makes both mold ends
Linear distance is elongated；When rotating counterclockwise adjusting nut 22, the distance of two counterscrews 21 is moved closer to, and makes both mold ends
Linear distance shorten；Therefore the straight length tune of its long axis direction can be easily realized in the winding process of oblong coil
Section.
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.
