The Main Function Of Ac Reactor

AC Reactors plays multiple important roles in the power system, and its main functions include:

Harmonic suppression: AC reactors can effectively suppress the harmonic components in the current, reduce the interference and harm of harmonics to the power system, and protect the safe operation of the electromechanical system.

Improve voltage distribution: When the power equipment is heavily loaded or the system is short-circuited, AC reactors can improve voltage distribution, reduce the voltage burden of equipment such as transformers, and prevent equipment from overload operation.

Reduce power frequency transient overvoltage: When the system has a short circuit fault or a transition process, AC reactors can reduce power frequency transient overvoltage and protect power equipment from overvoltage damage.

Improve the stability of the power system: AC reactors can reduce voltage fluctuations and oscillations caused by load changes or power system failures, thereby avoiding power system collapse and power outages.

Extend the service life of power equipment: By protecting power equipment from high temperature and overvoltage damage, AC reactors help extend the service life of equipment, while improving the efficiency of transformers and reducing energy waste.

Limit short-circuit current: AC reactors can effectively limit short-circuit current and protect electrical equipment from excessive current shock.

Improve power factor: AC reactors can be used to compensate for reactive power and improve the power factor of the system, thereby improving the efficiency of the power system.

Filtering and voltage stabilization: In power electronic equipment, AC reactors are often used in filtering circuits to smooth output voltage and current and reduce ripple, and in voltage stabilization circuits to stabilize output voltage and prevent voltage fluctuations from affecting the load.

In summary, AC reactors play an important role in power systems, protecting power equipment from interference and damage such as overvoltage and harmonics, improving the stability and reliability of power systems, and extending the service life of equipment.
