At present; voltage stabilizer is widely used in all needs the stable place of voltage; the compensation electric power voltage stabilizer of full-automatic high-power; have that capacity is big, efficient is high, voltage stabilized range is wide, the precision of voltage regulation is high, defencive function is strong, have no waveform distortion, the incomparable advantage of many other types voltage stabilizers such as reliable, easy maintenance, be the leading products of voltage stabilizer industry for many years always.
Be subjected to compensated voltage regulator mainly to make the restriction of starting material fibre glass cover wire and technique for coiling thereof, compensated voltage regulator single-stage tracking peak power is 1200KVA (voltage compensation scope ± 20%, a voltage stabilizing output accuracy 3%), can't satisfy the more requirement of large-capacity user.Once there was producer to adopt the two-stage series connection compensation, i.e. two compensated voltage regulators series connection, the mode of every each compensation ± 10% increases high capacity, because of the complicated degree of restricted work, cost and safeguard the restriction of aspect factor, finally can't be accepted by market success.
Now all producers all divide the mode of transferring to come increase capacity (as Chinese patent ZL200820055280.6) with parallel three phase, this serial voltage stabilizer is mainly overlapped corresponding carbon brush group with three comprehensive compensation transformers and three and is formed by three control circuits, three cover motor transmission mechanisms, three comprehensive adjustable transformers, in the three-phase which differs mutually, motor drives that phase carbon brush group action devious, to reach the effect of voltage stabilizing, its complex structure, cost height, branch transfer effect bad.
The utility model content
The purpose of this utility model is to provide a kind of output voltage balance, volume is little, consumable quantity is few parallel three phase tracking voltage stabilizer.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of parallel three phase tracking voltage stabilizer, and it mainly is made up of comprehensive adjustable transformer, three-phase compensator transformer, contactor control circuit, voltage detection unit, control system and holding circuit; The voltage detection unit outer end connects the civil power input and output side, and inner connection control system is transferred to control system with detection signal; The output terminal one tunnel of control system connects the input end of contactor control circuit, the output terminal of contactor control circuit connects the input end of three-phase compensator transformer, the output terminal of three-phase compensator transformer connects comprehensive adjustable transformer by the inductor holding circuit, and another road connects comprehensive adjustable transformer; Described holding circuit connection control system.Comprehensive adjustable transformer is three-phase transformer or single transformer or is composed in parallel by two or more unit adjustable transformer.Control system is electrically connected servomotor, and electromechanics connects gear train and moves together by the three-phase carbon brush group that gear train drives in Liang Tai and the comprehensive adjustable transformer more than two, reaches the output voltage unanimity.
After adopting such scheme, the utility model is to be based upon original three-phase system to divide on the accent voltage stabilizer basis, original three relative each be separate compensation mutually, drive the voltage stabilizing of cover three-phase carbon brush group by control system control servomotor, to satisfy the requirement of high capacity voltage stabilizer.Because the utility model is sampled by voltage detection unit, detect the also rotation of output signal control servomotor, drive carbon brush group on the comprehensive adjustable transformer slides and regulates the secondary voltage of adjustable transformer through reducing gear and by chain, to change the polarity and the size of bucking voltage, realize that output voltage autostable is in the scope that precision allows is adjusted in voltage stabilizing.So advantage such as the utlity model has the output voltage balance, volume is little, consumable quantity is few.
