The structure of a reactor is relatively simple, usually consisting of a coil and an iron core. The coil is the main component of the reactor, which regulates the current in the circuit by winding and changing its position. The function of the iron core is to increase the inductance in the circuit, further adjusting the efficiency and power factor of the circuit.
The working principle of a reactor is based on the principle of inductance. Inductance refers to the ability to obstruct changes in current. In a circuit, inductance prevents instantaneous changes in current and maintains a steady flow of current for a long time. By introducing appropriate inductance, the current in the circuit can be stabilized, avoiding excessive or insufficient current that may affect the normal operation of the circuit.
Reactors also include the function of capacitors. By introducing appropriate capacitors, the power factor of the circuit can be improved. Capacitors can store and release electrical energy in AC circuits, effectively balancing power fluctuations and peaks in the circuit and improving its efficiency.
