What Is The Function Of Ac Reactor?

The main functions of AC Reactors are to limit current, provide reactive power, control voltage, improve power system efficiency, and have anti-interference and equipment protection characteristics. Specifically:

‌Limit current‌: AC reactors can limit current overcurrent and short circuit, and protect power equipment from safe operation.

‌Provide reactive power‌: In the power system, AC reactors can provide reactive power and balance the active power in the power system.

‌Control voltage‌: By adjusting the combination of capacitors and inductors, AC reactors can control voltage to ensure voltage stability in the power grid.

‌Improve power system efficiency‌: The use of AC reactors can reduce current loss in the power grid and improve the overall efficiency of the power system.

‌Anti-interference and equipment protection‌: AC reactors can prevent the high-order harmonics formed by electrical equipment from "polluting" the power grid, protect the power electronic components of the drive mechanism, prevent tripping caused by voltage spikes of the main power supply, and protect the power switching devices inside the inverter, etc.

‌Smoothing and noise reduction‌: AC reactors can also be used for smoothing, reducing transient voltages, extending motor life, and reducing motor noise and eddy current losses‌.

In summary, AC reactors play a vital role in power systems and are important electronic components to ensure safe and stable operation of power grids.
