The three-phase AC voltage regulator manufacturer introduces the classification of voltage regulators. The AC voltage stabilized power supply has a wide range of uses and types, which can be roughly divided into the following five types:
① Ferromagnetic resonance AC voltage stabilizer: it is an AC voltage stabilizer made of the combination of saturated choke and corresponding capacitor with constant voltage volt ampere characteristics Magnetic saturation type is the early typical structure of this regulator. It has the advantages of simple structure, convenient manufacture, wide allowable variation range of input voltage, reliable operation and strong overload capacity However, the waveform distortion is large and the stability is not high The voltage stabilizing transformer developed in recent years is also a power supply device that realizes the voltage stabilizing function with the help of the nonlinearity of electromagnetic components The difference between it and magnetic saturation regulator lies in the different structure of magnetic circuit and the same basic working principle It has dual functions of voltage stabilization and transformation on one core, so it is superior to ordinary power transformer and magnetic saturation regulator
② Magnetic amplifier AC voltage regulator: a device that connects a magnetic amplifier and an autotransformer in series and uses electronic circuits to change the impedance of the magnetic amplifier to stabilize the output voltage The circuit can be linear amplification or pulse width modulation This kind of regulator has a closed-loop system with feedback control, so it has high stability and good output waveform However, due to the use of magnetic amplifier with large inertia, the recovery time is longer
③ Sliding AC voltage regulator: a device that changes the position of the sliding contact of the transformer to stabilize the output voltage, that is, an automatic voltage regulating AC voltage regulator driven by a servo motor This kind of regulator has high efficiency, good output voltage waveform and no special requirements for load properties But the stability is low and the recovery time is long
④ Induction AC voltage regulator: a device that stabilizes the output AC voltage by changing the phase difference between the secondary voltage and the primary voltage of the transformer It is similar to wire wound asynchronous motor in structure and induction voltage regulator in principle Its stable voltage range is wide, the output voltage waveform is good, and the power can reach hundreds of kilowatts Because the rotor of the regulator is often locked, the power consumption is large and the efficiency is low In addition, copper and iron are less produced due to their large amount of materials
⑤ Thyristor AC voltage regulator: AC voltage regulator using thyristor as power adjusting element It has the advantages of high stability, fast response and no noise However, it may cause interference to communication equipment and electronic equipment due to damage to the city's radio wave shape.
High power AC stabilized voltage power supply has been widely used in industrial automation, complete sets of equipment, CNC machine tools, textile, medical treatment, hotels, radio and television, communication equipment and other occasions requiring voltage stability For some equipment components and applications and systems, voltage fluctuations are dangerous and must be controlled For example, high-precision printing equipment (such as offset press, flexographic press, large gravure press, etc.) needs a stable voltage environment, and the more sensitive components need power protection. The control part can work normally within 3% of the small voltage fluctuation, but the fluctuation exceeds the normal range value, which will cause direct or indirect losses, make the equipment unable to operate normally, even burn the circuit board, and shorten the service life of the equipment
