Technical field
The utility model relates to a kind of transformer, especially a kind of three-phase voltage stabilizing transformer loop construction exporting compensate function with counter voltage.
Background technology
Three-phase transformer, as the equipment realizing voltage transitions, is widely applied in power industry, and its structure composition can be realized by the input and output end-coil that coiling on three core limbs is corresponding.At present; the structure of the main flow three-phase transformer product on market is stable not; be unfavorable for that manufacturer carries out large-scale production to obtain cost advantage, especially in the high accuracy of stable output facet from market demands, three-phase voltage stabilizing transformer certain gap in addition of high reliability of control voltage.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of efficient energy-saving, the band counter voltage that stable and cost performance is high to export the three-phase voltage stabilizing transformer loop construction of compensate function.
The technical solution of the utility model is: counter voltage exports the three-phase voltage stabilizing transformer loop construction compensated, comprise main iron core, first secondary iron core, second secondary iron core and several coil windings, it is characterized in that: described main iron core fixedly forms by some layers of lamination is superimposed, every layer of lamination is by one piece of rectangular iron chip I, rectangular iron chip II and the two piece same shape of three pieces of same shapes and size and the rectangular iron chip III of size are put together, first secondary iron core and the second secondary iron core fixedly form by some pieces of E shape lamination IV are superimposed, first secondary iron core to be positioned at above main iron core and to be arranged with three input offset coils, three parallel columns core tops of main iron core are arranged with and three input offset coils, three input coils one to one, described input coil connects with corresponding input offset coils connected in series, three parallel columns core bottoms of main iron core are arranged with and three input coils, three output windings one to one, second secondary iron core to be positioned at below main iron core and be arranged with three output windings one to one three export bucking coil, described output bucking coil is connected in series with corresponding output winding.
Preferably, described main iron core is fixedly formed slotting superimposed through multilayer by rectangular iron chip; Described rectangular iron chip I is provided with a fixing hole, and rectangular iron chip II is provided with two fixing holes, and rectangular iron chip II is provided with five fixing holes; Described E shape lamination IV is provided with five fixing holes.
Operation principle of the present utility model is: due to the output voltage U of three-phase transformer
export=U
c-U
d, wherein U
cfor output end voltage, U
dfor reference-junction compensation voltage.The utility model exports bucking coil winding Wd by setting up at output, carries out reverse voltage U on this winding by changing both positive and negative polarity mode simultaneously
dcompensate, and along with output winding winding W
coutput voltage U
cincrease Synchronization Control increase reverse output voltage U
d, thus the reverse voltage realizing transformer exports compensate function.
The beneficial effects of the utility model are: 1, be easy to install, Stability Analysis of Structures, production cost is low, efficient energy-saving, and work is more stable, and long service life, cost performance is high.2, when input voltage (line voltage) distortion, U is made
cvoltage deducts U
dcounter voltage, the distortion factor is little, and the precision of voltage regulation is high.3, when input voltage is larger, the U deducted
dcounter voltage is larger, makes output voltage step-down, thus can not produce overvoltage output.
