Abstract
A simulated voltage transformer suitable for scientific research and testing comprises a housing, a main iron core and windings, and is characterized in that the main iron core is in the shape of a ring; the windings are continuously wound around the main iron core; a gap is reserved between the adjacent windings; strip-shaped moveable iron cores radially distributed are additionally arranged outside the radial surface of the main iron core; and all the strip-shaped moveable iron cores can move forwards and backwards relative to the gaps between the windings respectively. The main iron core is in the shape of the ring without seams, so that the no-load loss, the no-load current and the magnetic flux density are greatly reduced, and the impedance angle is high; and the movable iron cores are additionally arranged, and the magnetic flux leakage between the windings is changed by moving the movable iron cores, so that the uninterrupted adjustment to impedance and voltage can be realized conveniently.
Description
Technical field
The utility model relates to a kind of special transformer, particularly a kind of analogue transformer that is applicable to scientific research and testing.
Background technology
Analogue transformer is the special transformer of simulating huge power transformer physical parameter with miniature transformer, is the operation of research electric power system and the visual plant of ultra high voltage product testing.At present, analogue transformer mostly is dry type, " mouth " font twin columns laminated core, " cake formula " winding construction, because of its iron core knot seam is many, causes leakage reactance big, the loss height, and no-load current is big, and impedance angle is low, and the impedance adjustment inconvenience can not satisfy test and use.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, and provide that a kind of loss is low, no-load current is little, impedance angle is high, impedance adjustment novel analog transformer easily.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is: analogue transformer comprises shell, main iron core, winding, it is characterized in that its main iron core is an annular, winding is wound on the main iron core continuously, leave the space between the adjacent winding, have additional the moving iron core of radially-arranged bar shaped outside the main iron core diametric plane, the space that every moving iron core of bar shaped corresponds respectively between the winding can move forward and backward.
The utility model is owing to adopt above design, and main iron core is an annular, and no seam greatly reduces zero load fall from the sky or outer space consumption, no-load current and magnetic flux density, impedance angle height, no-load loss P
0%＜1.0%, no-load current I
0%＜1.5%, short-circuit impedance angle are not less than 88 degree.Set up moving iron core, by moving the leakage flux between the moving iron core position change winding, that can conveniently realize impedance, voltage does not regulate impedance drop adjustable range U at interval
k%=10%～30% is adjustable continuously.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left pseudosection of Fig. 1;
Fig. 3 is the panel schematic diagram.
Embodiment
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
As shown in the figure, be example with single-phase double winding product, analogue transformer comprises shell 1, main iron core 2, winding 3.That main iron core 2 adopts is cold rolling, orientation, low-loss laser sheet are made into annular.Winding 3 is wound on continuously on the main iron core 2 by the stranded lead of outsourcing insulation afterwards of even transposition by many polyester paint envelope curves and constitutes, and leaves space 4 between the adjacent winding, and the main iron core 2 behind the coiling winding 3 is fixed on shell 1 inner bottom plating by device body clamping plate 5.Outside main iron core 2 diametric planes, have additional the moving iron core 6 of radially-arranged bar shaped, the moving iron core 6 of bar shaped is by fastening the forming of silicon steel sheet stack, the moving iron core 6 of every bar shaped corresponds respectively to the space 4 between the winding 3, the moving iron core 6 of bar shaped by bracing frame 7 be fixed in the shell 1, by be connected gag lever post between bracing frame 7 two ends 8 spacing, can manually it be moved forward and backward by drive screw 9 by its center.Each lead leading-out terminal leads on the panel, easy-to-connect, and thread-changing is easy.
